At 2:53 p.m. EDT, the Orion spacecraft ignited its thrusters for 8 seconds, producing a change in velocity of 4.2 feet-per-second and pushing Artemis II toward Earth. NASA astronauts Reid Wiseman, Victor Glover, Christina Koch and CSA (Canadian Space Agency) astronaut Jeremy Hansen reviewed procedures and monitored the spacecraft’s configuration and navigation data.
The crew continues to wrap up cabin configuration for re-entry and move into their entry checklist.
Splashdown is targeted for 8:07 p.m. EDT (5:07 p.m. PDT) off the coast of San Diego, where NASA’s recovery team will be standing by to welcome the Artemis II crew home.

Coverage will continue until NASA and Department of War personnel safely assist the crew out of Orion and transport them to the USS John P. Murtha.
At 10:53 p.m. EDT, the Orion spacecraft executed a brief nine-second thruster burn, increasing its velocity by 5.3 feet per second and nudging the Artemis II crew further along their return path to Earth.
With the maneuver complete, the crew has now crossed the halfway mark on their journey home.
Temporary Signal Loss Resolved
Roughly two hours before the burn, mission teams encountered an unexpected return link loss of signal during a data rate transition, briefly disrupting the flow of communications and telemetry from the spacecraft.
Two-way contact was subsequently restored, allowing flight controllers and crew to resume preparations for the scheduled maneuver without further delay.

Re-Entry Briefings And Next Steps
Earlier in the day, officials from NASA provided additional details on re-entry and splashdown procedures during a mission status briefing.
The next key milestone—a third return trajectory correction burn—is planned for April 10 at approximately 1:53 p.m., ahead of final re-entry operations.
Splashdown Target Remains On Track
NASA continues to target splashdown at 8:07 p.m. (5:07 p.m. PDT) on Friday, April 10, off the coast of San Diego, as the Artemis II mission enters its final phase of return.
Dan Florez is one of the NASA test directors for the Exploration Ground Systems Program. The test directors are a group of 20 engineers at the agency’s Kennedy Space Center in Florida who plan and execute integrated testing for Artemis missions. Their work includes developing timelines and procedures for launch countdown, propellant loading, emergency egress, pad and launch abort scenarios, recovery operations, and more. They help lead the ground systems team in all areas of testing.
At the time of Artemis I launch, Florez and his fellow test directors had already developed the launch countdown timelines for Artemis II.
“We were really focused on loading that spacecraft with cryogenic propellants and successfully launching it. With Artemis II, we’re going to have to do all that again, but in the middle of that, we’re going to have to embed the crew timeline to get the crew safely inside the spacecraft, get all the systems checked out, and launch them into space,” Florez said. “And we have to do the same thing on the tail end through recovery. So, there’s a lot of complexities when you have the human element thrown into the operation.”
Since Artemis I, Florez has focused his work even more heavily on the human element, taking on rescue and recovery operations.
“We have to have a plan to go get to the crew if we have an abort, if we land anywhere in the world within 24 hours,” said Florez. “My role right now is to do a lot of that coordination to make sure we have all the assets and all the resources in place to get to the crew.”
When the Artemis II crew returns to Earth aboard the Orion spacecraft, Florez will be there, prepared and ready with NASA’s Landing and Recovery Team and the U.S. military.
“We have a great partnership with the military. We have the Human Spaceflight Support Office within the Air Force that support us directly for not just for recovery operations, but also for any of the rescue operations”.
Dan Florez, NASA Test Director, Exploration Ground Systems Program
Recovery operations are routinely verified and validated in what is called an underway recovery test. NASA and Navy teams board a U.S. Navy ship and travel off the coast of San Diego to test retrieving the capsule and getting the crew safely on the ship. In late February 2024, the Artemis II crew joined the recovery team’s eleventh iteration of testing called, URT-11.
“It was really great to have that perspective of having astronauts in the loop during our test operations,” said Florez. “Everywhere along the way, we got feedback from them.”
Artemis II launched at 6:35 p.m. EDT April 1, from Launch Complex 39B, sending NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, on their approximately 10-day mission around the Moon.

Florez and his colleagues are prepared and ready to apply everything they tested to recover the crew.
“Watching them launch is going to be great. I’m going to be happier when they land”.

Soon after the mission’s launch on April 1, 2026, at 6:35 p.m. EDT, NASA’s Near Space Network led communications with the Orion capsule. Then, communications were handed off to the DSN, marking the first time in over 50 years that the network would be communicating with a crewed spacecraft traveling through deep space.
The Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory in Southern California (where this photo was taken) operates the DSN, which comprises three complexes in Goldstone, California; Madrid, Spain; and Canberra, Australia. Each complex consists of several radio frequency antennas that communicate with dozens of robotic spacecraft exploring the solar system in addition to the Artemis II mission.
A graphical representation of the Deep Space Network’s radio frequency antennas indicate signal acquisition from NASA’s Artemis II mission to the Moon on April 1, 2026, inside the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory in Southern California. Two antennas at the Madrid Deep Space Communications Complex, Deep Space Station 54 and 56, can be seen communicating with Artemis II (the signals are labelled “EM2”, short for “Exploration Mission 2”; elsewhere they are labelled “ART2” for “Artemis II”).
A similar visualization can be found at DSN Now, which details all the missions that the network is communicating with 24 hours a day, seven days a week.
NASA
The DSN is managed by JPL for the agency’s Space Communications and Navigation program, which is located at NASA Headquarters within the Space Operations Mission Directorate. The DSN allows missions to track, send commands to, and receive scientific data from faraway spacecraft. JPL is managed by Caltech in Pasadena, California, for NASA.
NASA’s Artemis II mission is drawing support from a pair of nearly identical control rooms in Alabama, each playing a distinct role in keeping astronauts safe and operations on track as the crew heads back to Earth, Friday, April 10.
At the National Aeronautics and Space Administration’s Marshall Space Flight Center in Huntsville, two facilities, the Lunar Utilization Control Area (LUCA) and the Lander Engineering Support Area (LESA), are working in tandem during the mission. Both are housed within the Huntsville Operations Support Center, a hub designed to provide real-time technical and scientific support.
Though similar in appearance, the two rooms serve different purposes. LUCA focuses on science operations linked to Artemis, while LESA is geared toward engineering support, particularly for future missions that will land astronauts on the Moon.
LUCA (Lunar Utilization Control Area) at NASA Marshall is specially designed to support a wide variety of science operations on and around the Moon – and beyond. Engineers in the LUCA monitored operations for the Lunar Node-1 experiment, an autonomous navigation payload that was part of the first NASA Commercial Lunar Payload Services (CLPS) launch on Intuitive Machines’ Nova-C lunar lander in 2024. NASA Marshall flight controllers will use the LUCA again for Artemis II to monitor science operations. NASA/Charles Beason
Officials say the flexibility of the Huntsville center allows it to adapt to evolving mission needs. The facility has previously supported programs including the Commercial Crew Program, the Space Launch System rocket and research aboard the International Space Station.
Teams operating from LUCA are currently supporting science experiments tied to deep space conditions. These include studies examining how microgravity and radiation affect the human body, including immune response and overall performance. Data gathered during Artemis II is expected to shape planning for future crewed missions beyond Earth orbit.
Support engineers will use the LESA (Lander Engineering Support Area) at NASA Marshall to monitor human landing system (HLS) for the first crewed Artemis missions. NASA/Charles Beason
In parallel, LESA teams are monitoring Artemis II operations in real time, using the mission as a live test case to refine procedures ahead of future lunar landings. Engineers, safety specialists and flight operations experts form part of the Human Landing System Mission Insight Support Team, which will eventually play a central role in supporting lander systems during Moon missions.
The Huntsville Operations Support Center also provides a range of technical services, including spacecraft command and telemetry management, global voice communications, and live and recorded video support. It also deploys specialized software tools that enable seamless data exchange between systems located far apart, allowing teams across different locations to work in sync.
By integrating these capabilities into both LUCA and LESA, NASA enables continuous coordination between engineers, scientists and mission operators worldwide.
Artemis II, which recently carried astronauts around the Moon, is part of NASA’s broader Artemis program aimed at returning humans to the lunar surface. The program is also intended to lay the groundwork for future missions to Mars, with lessons from current flights feeding directly into long-term exploration plans.
Artemis II moved into another critical phase of its return journey as the crew began Flight Day 8 with a focus on testing systems and preparing for reentry.
Aboard the Orion spacecraft, named Integrity, the four astronauts woke to music and a message from the Canadian Space Agency. At the start of the day, they were about 200,278 miles from Earth and 83,549 miles from the Moon, steadily closing the distance after their lunar flyby.
The crew, NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, along with CSA astronaut Jeremy Hansen, began the day with their routine exercise session. Using a flywheel device, they performed a mix of aerobic and resistance workouts designed to counter the physical effects of microgravity. The system relies on a cable-based mechanism that enables movements such as rowing, squats and deadlifts.
Moon Joy art002e013367 (April 7, 2026) – The Artemis II crew – (clockwise from left) Mission Specialist Christina Koch, Mission Specialist Jeremy Hansen, Commander Reid Wiseman, and Pilot Victor Glover – take time out for a group hug inside the Orion spacecraft on their way home. Following a swing around the far side of the Moon on April 6, 2026, the crew exited the lunar sphere of influence (the point at which the Moon’s gravity has a stronger pull on Orion than the Earth’s) on April 7, and are headed back to Earth for a splashdown in the Pacific Ocean on April 10. The crew was selected in April 2023, and have been training together for their mission for the past three years. Image Credit: NASA
Attention then shifted to a key physiological test.
Each astronaut is scheduled to evaluate an orthostatic intolerance garment worn beneath the Orion Crew Survival System suit. The garment is designed to help regulate blood pressure and circulation as the body readjusts to gravity. After extended periods in space, some astronauts experience dizziness or fainting when standing, a condition linked to reduced cardiovascular adaptation. The compression provided by the garment aims to reduce that risk and support a smoother transition during landing and recovery.
Later in the day, the crew is expected to speak with media following their recent journey around the Moon. NASA said journalists must confirm participation in advance to join the scheduled call. To join the call virtually, media must RSVP no later than 1 p.m.
(April 7, 2026) – The Artemis II crew – (clockwise from left) Mission Specialist Christina Koch, Mission Specialist Jeremy Hansen, Commander Reid Wiseman, and Pilot Victor Glover – pause for a group photo with their zero gravity indicator “Rise,” inside the Orion spacecraft on their way home. Following a swing around the far side of the Moon on April 6, 2026, the crew exited the lunar sphere of influence (the point at which the Moon’s gravity has a stronger pull on Orion than the Earth’s) on April 7, and are headed back to Earth for a splashdown in the Pacific Ocean on April 10.
Operational testing will continue into the evening.
After their midday meal, the astronauts will take manual control of Orion for another piloting demonstration. Using the spacecraft’s forward viewing window, they will align with a designated target and guide the capsule into a tail-to-Sun orientation. The exercise is intended to gather additional data on Orion’s handling characteristics and its guidance, navigation and control systems.
Maintaining that orientation also helps regulate thermal conditions and supports efficient power generation through solar exposure. Similar piloting exercises were carried out earlier in the mission, including during proximity operations testing.
Preparation for the final phase of the mission is already underway.
Crew members and flight controllers are expected to begin configuring the cabin for reentry, securing equipment and installing seats ahead of splashdown. NASA said teams decided to skip a previously planned shielding deployment demonstration in order to prioritize entry readiness.
The National Aeronautics and Space Administration is targeting splashdown at 8:07 p.m. Eastern Time on Friday, April 10, in the Pacific Ocean off the coast of San Diego. Officials said updates on weather and recovery operations will continue through daily mission briefings broadcast on the agency’s official channels.
Astronauts aboard the International Space Station spoke with the Artemis II crew on April 8 following their lunar flyby, marking a rare ship-to-ship exchange between deep space and low Earth orbit. The Artemis II crew is returning to Earth after circling the Moon, while Expedition 74 astronauts continued biomedical research and mission training aboard the station. The interaction highlighted how ongoing ISS science supports future lunar missions under NASA’s Artemis program.
For a few minutes on Tuesday, two crews separated by hundreds of thousands of miles shared the same conversation.
Astronauts aboard the International Space Station (ISS) connected with their counterparts on NASA’s Artemis II mission, offering a rare moment of overlap between low Earth orbit operations and deep space travel. The call came just a day after Artemis II astronauts completed a historic lunar flyby and began their journey home.
On one side were Expedition 74 crew members Chris Williams, Jack Hathaway and Jessica Meir of NASA, along with Sophie Adenot of the European Space Agency (ESA). On the other were Artemis II astronauts Reid Wiseman, Victor Glover and Christina Koch, joined by Jeremy Hansen of the Canadian Space Agency (CSA).
The Artemis II crew is traveling aboard Orion, returning to Earth after looping around the Moon in NASA’s first crewed lunar mission in decades.
ISS and Artemis II crew exchange experiences after lunar flyby
The conversation turned quickly to comparison.
Station astronauts asked about differences between spacecraft, while Artemis II crew members described the experience of seeing the Moon up close. Christina Koch, drawing on her own time aboard the ISS, linked the two missions directly.
“Every single thing that we learned on ISS is up here,” Koch said, referring to how station-based training translates to deep space operations.
The exchange underscored a key role of the ISS within the Artemis program. The orbiting laboratory functions as a proving ground where astronauts refine procedures, test systems and adapt to long-duration spaceflight before venturing farther from Earth.
For NASA and its partners, that continuity is central. The Artemis II mission builds on lessons accumulated over years of station operations.
The Artemis II crew – (clockwise from left) Mission Specialist Christina Koch, Mission Specialist Jeremy Hansen, Commander Reid Wiseman, and Pilot Victor Glover – pause for a group photo with their zero gravity indicator “Rise,” inside the Orion spacecraft on their way home. Following a swing around the far side of the Moon on April 6, 2026, the crew exited the lunar sphere of influence (the point at which the Moon’s gravity has a stronger pull on Orion than the Earth’s) on April 7, and are headed back to Earth for a splashdown in the Pacific Ocean on April 10.
Space station biomedical research supports Artemis and future missions
While the call captured public attention, the station’s daily schedule remained anchored in research.
Crew members conducted a series of biomedical scans using the Ultrasound 3 device, focusing on how spaceflight affects the human body. Doctors on the ground monitored the scans in real time, looking for signs of blood clots that can form in leg veins and travel to the lungs.
Such risks have become a growing area of study as missions extend beyond short orbital stays. Data collected aboard the ISS feeds directly into planning for longer journeys, including missions to the Moon and eventually Mars.
Jessica Meir also contributed to the RelaxPro investigation, an ESA-sponsored study examining stress and immune responses in space. She collected saliva and hair samples that researchers will analyze on Earth for hormonal and immune markers.
The study explores whether mindfulness and meditation techniques can improve sleep quality and reduce stress during long-duration missions.
Cargo mission training and robotic systems testing on ISS
Operational training continued alongside scientific work.
Williams and Hathaway simulated the capture of the Cygnus XL cargo spacecraft using the Canadarm2 robotic system. Mission planners are targeting April 10 for the launch of the resupply mission aboard a **SpaceX Falcon 9 rocket, which will deliver supplies and experiments to the station.
Elsewhere, Sophie Adenot worked inside the Japanese Kibo laboratory module, setting up a compact experimental robotic arm known as TUSK. The system is being tested for precise movements at sub-millimeter levels in microgravity, a capability that could support delicate operations in future missions.
Adenot later joined fellow astronauts for emergency response simulations, rehearsing procedures designed to prepare crews for unexpected situations in orbit.
Roscosmos crew studies teamwork and fitness in orbit
Russian crew members also focused on research tied to long-duration missions.
Station commander Sergey Kud-Sverchkov and flight engineer Sergei Mikaev, both representing Roscosmos, participated in experiments examining team dynamics and physical conditioning in space. One study involved progressively complex computer tasks requiring cooperation, allowing researchers to observe how crews adapt to working together in confined environments.
The findings may influence crew training for future missions beyond Earth orbit.
Kud-Sverchkov later completed a monitored exercise session using an onboard cycle, while Mikaev assisted with health data collection.
Meanwhile, Andrey Fedyaev continued training with the European robotic arm inside the Nauka module, practicing both primary and backup control modes to ensure operational readiness.
The day’s activities reflected a layered mission environment.
On one level, astronauts pushed the boundaries of human spaceflight, exchanging insights between deep space and orbit. On another, they maintained a steady cadence of experiments and training that will shape future exploration.
The Artemis II crew moves farther from the Moon with each passing hour. The ISS crew remains in orbit, continuing work that helps make those journeys possible.
NASA’s Artemis II crew began their return journey to Earth on April 7 after completing a historic lunar flyby a day earlier. The crew, traveling aboard the Orion spacecraft about 236,000 miles from Earth, exited the Moon’s gravitational influence and initiated return procedures. The mission includes a call with International Space Station astronauts, scientific debriefs, and a planned trajectory correction burn to refine their path home.
The Artemis II crew woke to music and a long journey ahead.
Less than 24 hours after looping around the Moon, four astronauts aboard NASA’s Orion spacecraft began the slow pivot back toward Earth. They started Flight Day 7 roughly 236,000 miles from home, still carrying the momentum of a mission that marked humanity’s first crewed lunar flyby since Apollo-era flights more than five decades ago.
The crew of National Aeronautics and Space Administration (NASA) astronauts Reid Wiseman, Victor Glover and Christina Koch, along with Canadian Space Agency (CSA) astronaut Jeremy Hansen, crossed a key threshold early in the day. At 1:23 p.m. Eastern Time, Orion exited the Moon’s sphere of influence, the region where lunar gravity dominates spacecraft motion.
That transition marked a turning point. From that moment, Earth’s gravity again became the primary force shaping Orion’s path.
A quiet shift. But a decisive one.

Artemis II crew ISS call with Expedition 74 astronauts
Even as the spacecraft moved farther from the Moon, the crew maintained contact with colleagues in orbit closer to Earth.
At 2:40 p.m., Artemis II astronauts connected with crew members aboard the International Space Station (ISS) for a scheduled 15-minute audio call. On the station were NASA astronauts Jessica Meir, Jack Hathaway and Chris Williams, along with European astronaut Sophie Adenot of the European Space Agency (ESA).
The exchange, broadcast via NASA’s official channels, offered a rare ship-to-ship moment between astronauts operating at vastly different distances from Earth.
Such interactions serve both technical and symbolic purposes. They allow crews to compare conditions, share observations, and reinforce coordination across missions that together define current human spaceflight.
Lunar flyby data and science debrief after close Moon pass
Attention quickly shifted from conversation to analysis.
At 3 p.m., the Artemis II crew joined science teams on the ground for a detailed debrief. The timing was deliberate. Mission planners wanted to capture observations while impressions from the lunar flyby remained fresh.
The April 6 flyby carried Orion around the far side of the Moon, a region not visible from Earth. During that pass, astronauts documented surface features, lighting conditions and spacecraft performance, data expected to support planning for future Artemis missions.
NASA has positioned Artemis II as a test flight. Its purpose extends beyond demonstration to refinement. Every observation feeds into subsequent missions, including planned crewed landings under the Artemis program.
Engineers and scientists are expected to analyze crew feedback alongside telemetry data in the coming weeks.
(April 6, 2026) – Captured by the Artemis II crew during their lunar flyby on April 6, 2026, this image shows the Moon fully eclipsing the Sun. From the crew’s perspective, the Moon appears large enough to completely block the Sun, creating nearly 54 minutes of totality and extending the view far beyond what is possible from Earth. The corona forms a glowing halo around the dark lunar disk, revealing details of the Sun’s outer atmosphere typically hidden by its brightness. Also visible are stars, typically too faint to see when imaging the Moon, but with the Moon in darkness stars are readily imaged. This unique vantage point provides both a striking visual and a valuable opportunity for astronauts to document and describe the corona during humanity’s return to deep space. The faint glow of the nearside of the Moon is visible in this image, having been illuminated by light reflected off the Earth. NASA
Orion return trajectory correction burn details and timing
The most critical maneuver of the day was scheduled for later.
At 9:03 p.m., Orion’s thrusters were set to ignite for the first of three planned return trajectory correction burns. These burns are designed to fine-tune the spacecraft’s path toward Earth, ensuring precise reentry conditions.
Christina Koch and Jeremy Hansen were assigned to monitor spacecraft systems and oversee procedures during the maneuver. Such burns require exact timing and calibration, as even small deviations at this distance can translate into large trajectory changes closer to Earth.
NASA officials have described the return phase as a series of incremental adjustments rather than a single decisive action. Each burn builds on the last, gradually aligning Orion with its targeted splashdown corridor.
Between scheduled tasks, the crew was given staggered off-duty periods.
The downtime serves operational needs as much as personal ones. Rest cycles help maintain cognitive performance, particularly as the mission enters phases requiring sustained attention and procedural accuracy.
NASA scheduled a mission status briefing later in the day to provide updates on spacecraft systems, crew health and trajectory progress.
The Artemis II mission, part of NASA’s broader Artemis program, aims to reestablish human presence beyond low Earth orbit. Unlike earlier missions confined to orbital paths around Earth, Artemis II pushes into deep space, testing systems required for sustained lunar exploration.
Flight Day 7 marked a transition from exploration to return.
The Moon receded behind them. Earth, still distant, became the destination again.
The four astronauts aboard NASA’s Artemis II mission woke up to a milestone few humans have experienced. Less than 19,000 miles from the Moon, they began final preparations for a lunar flyby that will mark humanity’s return to deep space after more than five decades.
Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen are expected to guide the Orion spacecraft through a carefully timed trajectory past the Moon later in the day. The moment carries symbolic weight. The last time humans ventured this far was during Apollo 17 in December 1972.
The crew’s wake-up call came with music. “Good Morning,” by Mandisa and TobyMac played through the spacecraft, followed by a recorded message from Apollo-era astronaut Jim Lovell, who died in 2025. Lovell commanded Apollo 13, the mission that previously held the record for the farthest distance traveled by humans from Earth.
That record is expected to fall at approximately 1:56 p.m. Eastern Time. Orion will surpass Apollo 13’s maximum distance of 248,655 miles, eventually reaching about 252,760 miles from Earth later in the evening.
“Hello, Artemis II! This is Apollo astronaut Jim Lovell. Welcome to my old neighborhood! When Frank Borman, Bill Anders, and I orbited the Moon on Apollo 8, we got humanity’s first up-close look at the Moon and got a view of the home planet that inspired and united people around the world. I’m proud to pass that torch on to you — as you swing around the Moon and lay the groundwork for missions to Mars … for the benefit of all. It’s a historic day, and I know how busy you’ll be. But don’t forget to enjoy the view. So, Reid, Victor, Christina, and Jeremy, and all the great teams supporting you – good luck and Godspeed from all of us here on the good Earth.”
Lovell,Gemini VII, Gemini XII, Apollo 8, and Apollo 13 Astronaut
Lunar Flyby Timeline And Observation Plans
The flyby itself is scheduled to begin around 2:45 p.m. Eastern Time and will span roughly seven hours. During this window, Orion will pass close enough to the lunar surface to allow astronauts to observe geological features in detail.
NASA has indicated that cameras mounted on Orion’s solar arrays will transmit live views of the Moon back to Earth. The agency plans to stream coverage across multiple platforms, including NASA+, YouTube, and major streaming services.
Engineers have cautioned that image quality may fluctuate. The distance from Earth, along with bandwidth constraints across NASA’s Deep Space Network, could affect transmission clarity during portions of the flyby.
The spacecraft’s closest approach is expected shortly after a planned communications blackout. At about 6:44 p.m., Orion will pass behind the Moon, temporarily losing contact with Earth as lunar mass blocks radio signals. The blackout is expected to last around 40 minutes.
Within that window, at approximately 7:02 p.m., Orion will reach its nearest point to the lunar surface, about 4,070 miles above it. This maneuver is critical for setting up the spacecraft’s trajectory for its return journey.
Final Flyby Preparations art002e009294 (April 6, 2026) – Artemis II Pilot Victor Glover, Commander Reid Wiseman, and Mission Specialist Jeremy Hansen prepare for their journey around the far side of the Moon by configuring their camera equipment shortly before beginning their lunar flyby observations.

Solar Eclipse Viewed From Deep Space
As the flyby concludes, the crew will witness a rare celestial alignment. Beginning around 8:35 p.m., the astronauts are expected to see a solar eclipse from their vantage point in space.
From Orion, the Moon will move directly between the spacecraft and the Sun, blocking sunlight for nearly an hour. The crew will observe the solar corona, the outermost layer of the Sun’s atmosphere, which becomes visible during such eclipses.
NASA officials have said this phase of the mission offers both scientific and experiential value. Observing the corona from deep space provides a unique opportunity to study solar activity without atmospheric interference.
The Artemis II mission is designed as a test flight, evaluating systems that will support future lunar landings under NASA’s Artemis program. Unlike later missions, Artemis II does not include a landing. Its focus remains on validating life support systems, navigation, and crew operations in deep space.
Still, Tuesday’s flyby represents a turning point. For the first time in more than 50 years, humans are returning to the Moon’s vicinity, setting the stage for a sustained presence in lunar orbit and, eventually, on its surface.
The spacecraft will continue its journey following the flyby, looping back toward Earth in the coming days.
Key moments for the lunar flyby include this following. All times are Eastern and may be adjusted based on real-time operations:
NASA
Monday, April 6
1:30 p.m.: The science officer in the Mission Control Center at NASA’s Johnson Space Center in Houston will brief the crew on their science goals for the upcoming flyby.
1:56 p.m.: The Artemis II crew is expected to surpass the record previously set by the Apollo 13 crew in 1970 for the farthest humans have ever traveled from Earth.
2:45 p.m.: Lunar observations begin.
6:44 p.m.: Mission control expects to temporarily lose communication with the crew as the Orion spacecraft passes behind the Moon.
6:45 p.m.: During “Earthset,” Earth will glide behind the Moon from Orion’s perspective.
7:02 p.m.: Orion reaches its closest approach to the Moon at 4,070 miles above the surface.
7:07 p.m.: Crew reach their maximum distance from Earth during the mission (252,706 miles).
7:25 p.m.: “Earthrise” marks Earth coming back into view on the opposite edge of the Moon.
7:25 p.m.: Mission control will re-acquire communication with the astronauts.
8:35-9:32 p.m.: During a solar eclipse, the Sun will pass behind the Moon from the crew’s perspective.
9:20 p.m.: Lunar observations conclude.
Tuesday, April 7
1:25 p.m.: Orion exits the lunar sphere of influence at 41,072 miles from the Moon.
Astronauts aboard Artemis II completed a 41-minute manual piloting test of the Orion spacecraft on Flight Day 4, taking turns controlling the vehicle in deep space. The demonstration, carried out tested thruster modes and maneuvering capabilities as the crew also reviewed targets for an upcoming lunar flyby. The mission continues on a stable trajectory toward the Moon, with further piloting tests planned later in the flight.
The astronauts aboard Orion spent part of their fourth day in space doing something few humans have ever done: manually steering a spacecraft far beyond Earth orbit.
Late in the day, Christina Koch and Jeremy Hansen took control of the capsule, guiding it through a series of controlled maneuvers designed to test how the spacecraft responds to human input in deep space.
The exercise began at 9:09 p.m. Eastern Daylight Time and lasted 41 minutes, giving engineers a detailed look at Orion’s handling under different conditions.
Orion manual piloting test evaluates deep space handling
During the demonstration, the astronauts tested two distinct thruster configurations. One allowed full six degrees of freedom, enabling movement and rotation across all axes. The other restricted motion to three degrees of freedom, simplifying control inputs and simulating different operational scenarios.
The goal is data. NASA engineers are studying how Orion behaves when astronauts take direct control, measuring responsiveness, stability, and precision. These findings will inform how future crews operate spacecraft during longer missions, where autonomy becomes essential.
Commander Reid Wiseman and pilot Victor Glover are scheduled to repeat the test on Flight Day 8, allowing ground teams to compare performance across different crew members.
Manual control remains a backup capability in modern spacecraft, but NASA continues to treat it as a core skill. In deep space, where delays in communication can limit ground intervention, astronauts must be able to operate independently if needed.
Lunar flyby imaging plan finalized ahead of observation window
While piloting tests drew focus late in the day, earlier hours were spent preparing for the mission’s next major milestone: the lunar flyby.
The crew reviewed a list of imaging targets prepared by NASA’s science team, outlining specific features on the Moon that astronauts will photograph and analyze during a six-hour observation period.
That window begins at approximately 2:45 p.m. on April 6, when Orion’s main cabin windows will be oriented toward the lunar surface.
The targets include impact craters, volcanic plains formed by ancient lava flows, and structural features such as ridges and fractures. By documenting variations in brightness, texture, and color, astronauts will contribute data that helps scientists interpret the Moon’s geological history.
Unlike earlier missions that passed close to the surface, Orion will observe the Moon from thousands of miles away. That distance allows the crew to capture a broader view, including polar regions that are difficult to study from low-altitude trajectories.
The planning session ensures that each crew member understands their role during the flyby. Timing, camera positioning, and observational priorities must align precisely during the limited window available.
Crew life aboard Orion blends routine with milestone moments
Even as the mission advances toward the Moon, daily life aboard Orion continues to follow a structured routine.
Earlier in the day, the astronauts used one of the spacecraft’s external solar array cameras to capture selfies, offering a glimpse of the crew inside the capsule as Earth recedes in the distance. The images are expected to be transmitted to mission control in the coming days.
Such moments, while informal, serve a broader purpose. NASA often shares these images to document the human experience of spaceflight, providing visual context for missions that otherwise unfold far from public view.
The crew is scheduled to begin their sleep period at 3:15 a.m., with mission control at the NASA Johnson Space Center set to wake them at noon Central Daylight Time to begin Flight Day 5.
Structured sleep cycles remain essential. Maintaining physical and cognitive performance is critical as the mission approaches its most observation-intensive phase.
Precision trajectory allows focus on operations
Artemis II continues along a stable trajectory toward the Moon, allowing astronauts to dedicate more time to operational tasks rather than propulsion adjustments.
NASA flight controllers have already canceled multiple planned trajectory correction burns, citing the spacecraft’s accurate path. That precision reduces workload on both the crew and ground teams while conserving fuel for later mission phases.
Inside Orion, that translates into a shift in focus. The early days of the mission emphasized propulsion and navigation. Now, attention has turned to piloting validation, scientific preparation, and system monitoring.
The manual piloting demonstration is part of that transition. It marks a point where the spacecraft is no longer just being guided by automated systems but is also being tested as a vehicle that astronauts can control directly in deep space.
As the Moon draws closer, the crew’s preparations inside the capsule are becoming more deliberate. Every maneuver, checklist review, and system test feeds into the upcoming flyby.
For now, the spacecraft continues forward on a steady path, with astronauts alternating between routine tasks and moments that underscore the scale of the mission.
NASA’s Artemis II crew began Flight Day 3 on April 4 after departing Earth’s orbit earlier in the mission, preparing for their first trajectory correction burn as Orion heads toward the Moon. The four astronauts, currently nearly 100,000 miles from Earth, are also training for lunar observations scheduled during a flyby on April 6. The day’s schedule includes spacecraft operations, medical drills, and communication system tests as the mission advances deeper into space.
The four astronauts aboard NASA’s Artemis II mission woke to music drifting through the Orion capsule, nearly 100,000 miles from Earth. Hours earlier, they had been asleep inside a spacecraft racing toward the Moon, farther from home than any crew in more than half a century.
Commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen are now settling into the cadence of deep-space flight. Their journey marks the first time humans have traveled beyond low Earth orbit since NASA’s Apollo program ended in 1972.
Mission controllers at NASA Johnson Space Center in Houston signaled the start of the day at 1 p.m. EDT, playing “…In a Daydream,” by the Freddy Jones Band. By then, Orion was roughly 99,900 miles from Earth, closing in on the Moon, which lay about 161,750 miles ahead.

Trajectory correction burn Artemis II timing and purpose
The crew’s primary task later Friday is preparing for the first outbound trajectory correction burn, scheduled for 6:49 p.m. The maneuver will last about eight seconds and slightly adjust Orion’s speed by 0.7 feet per second.
That small change carries weight in deep space navigation. Engineers design these burns to fine-tune the spacecraft’s path after major propulsion events, such as the translunar injection burn completed on April 2. Using Orion’s onboard thrusters, the adjustment ensures the capsule remains precisely aligned for upcoming lunar operations.
Inside the spacecraft, the preparation involves verifying propulsion systems, monitoring navigation data, and coordinating closely with mission control. Even minor deviations can compound over hundreds of thousands of miles, making these early corrections essential.
The Artemis II crew is experiencing this process in real time, managing both the technical and human demands of deep-space travel. It is the kind of operational rhythm that defined earlier lunar missions but has not been practiced by a human crew in decades.
Lunar flyby science targets and far side observations
While engineers refine Orion’s trajectory, scientists are focusing on what the crew will see once they reach the Moon.
Teams on the ground are selecting geological targets that will be visible during a six-hour observation window on April 6, when Orion loops around the lunar surface. The alignment of the Sun, Moon, and spacecraft is expected to illuminate about 20 percent of the Moon’s far side, a region never visible from Earth.
Among the features expected to come into view are the Orientale basin, a massive impact structure, along with Pierazzo crater and Ohm crater. Some of these formations have rarely been seen directly by human eyes without optical aid.
Inside Orion, the astronauts are rehearsing for that moment. The cabin, roughly the size of two minivans, requires careful choreography in microgravity. Equipment must be secured, camera positions planned, and movement coordinated to avoid disrupting observations.
The crew will use handheld cameras equipped with 80-400 millimeter and 14-24 millimeter lenses. These tools are expected to capture high-resolution imagery of the lunar surface, contributing to scientific analysis and public engagement with the mission.

The image features two auroras (top right and bottom left) and zodiacal light (bottom right) is visible as the Earth eclipses the Sun.
Orion spacecraft health tests and deep space communications
Beyond navigation and science, Flight Day 3 also includes routine but critical health and safety exercises.
The astronauts are scheduled to conduct demonstrations of cardiopulmonary resuscitation and choking response procedures. These drills aim to evaluate how emergency medical protocols function in microgravity, where movement and physical coordination differ significantly from Earth.
Physical fitness remains another priority. Each crew member continues daily exercise using Orion’s flywheel device, designed to maintain cardiovascular health during extended missions.
Later in the day, Christina Koch will test Orion’s emergency communication systems using NASA Deep Space Network, a worldwide array of antennas that supports spacecraft far beyond Earth orbit. The test will assess how effectively Orion can transmit data as it moves deeper into space.
The spacecraft’s optical communications system has already demonstrated its ability to send high-definition video and mission data back to Earth through U.S.-based ground stations. That information is relayed directly to mission control in Houston, allowing engineers to monitor the spacecraft’s performance in near real time.
As Artemis II advances toward its lunar flyby, the crew’s day-to-day work blends precision engineering with human adaptability. Each scheduled task, from an eight-second burn to a medical drill, contributes to a mission that is reestablishing a path last traveled more than five decades ago.
For the astronauts aboard Orion, the distance from Earth continues to grow. So does the scope of what lies ahead.
NASA approved the translunar injection burn for Artemis II on April 2, clearing the Orion spacecraft to leave Earth orbit at 7:49 p.m. EDT. The burn will send astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen toward the Moon for the first time since 1972. The decision follows a mission management review confirming spacecraft readiness and system performance.
The call came from Houston after a day of checks and calculations. The answer was simple. Go.
With that, NASA cleared Artemis II to attempt the maneuver that will send its crew beyond Earth orbit. If executed as planned, the burn will place humans on a path toward the Moon for the first time in more than five decades.
The mission marks a major step for the National Aeronautics and Space Administration and its Artemis program, which aims to return astronauts to deep space operations.
Translunar injection burn timing and Orion engine performance
The translunar injection burn is scheduled to begin at 7:49 p.m. Eastern Time. Orion’s main engine will fire for five minutes and 49 seconds, providing the acceleration needed to break free from Earth’s orbit.
The engine, located on the spacecraft’s service module, produces up to 6,000 pounds of thrust. NASA compares that output to accelerating a car from zero to 60 miles per hour in about 2.7 seconds.
The burn must be executed with precise timing and orientation. Even minor deviations can alter the spacecraft’s path over the hundreds of thousands of miles between Earth and the Moon.
Flight controllers will track engine performance, guidance systems, and navigation data in real time to ensure Orion remains aligned with its intended trajectory.

Crew activities and first full day operations in space
Earlier in the day, the Artemis II crew began their first full schedule of in-space operations. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch were joined by Jeremy Hansen of the Canadian Space Agency.
Mission control woke the crew at 2:35 p.m. Eastern Time with the song “Green Light” by John Legend and Andre 3000, continuing a long-standing NASA tradition of musical wake-up calls.
The astronauts moved into preparations for the burn, reviewing procedures and monitoring spacecraft systems. They also conducted their first exercise session using Orion’s flywheel-based device, designed to help maintain muscle and bone health in microgravity.
Exercise equipment is a standard feature for crewed missions, particularly those that extend beyond low Earth orbit. Maintaining physical conditioning becomes critical as mission duration increases.
The hours leading up to the burn are structured around system checks, communication with ground teams, and final readiness confirmations.
The Artemis II mission is designed as a test flight. Yet the stakes of this maneuver are clear. Once the engine fires, the crew will begin a journey that carries them away from Earth and toward the Moon, retracing a path last taken during the Apollo era.
NASA confirmed the Artemis II crew completed the perigee raise burn on April 2, firing Orion’s engine for 43 seconds to refine its orbit around Earth. The maneuver placed the spacecraft into a stable high Earth orbit ahead of a planned translunar injection later the same day. Mission managers will review system performance before approving the burn that would send astronauts toward the Moon for the first time since 1972.
The Artemis II crew woke to music and a tightly timed task. Minutes later, they were watching their spacecraft reshape its path around Earth.
Inside Orion, the capsule named Integrity, astronauts monitored systems as the engine fired for just over 40 seconds. The burn was brief. Its impact on the mission trajectory was not.
The maneuver marked another step in a sequence designed by the National Aeronautics and Space Administration to prepare astronauts for a return to deep space operations.
Perigee raise burn details and Orion orbit adjustment
The perigee raise burn began after a scheduled wake-up at 7:06 a.m. Eastern Time, when mission control in Houston signaled the crew with the song “Sleepyhead” by Young and Sick.
Shortly after, Orion’s service module main engine ignited. It burned for 43 seconds, increasing the spacecraft’s perigee, the lowest point in its orbit around Earth.
This adjustment refined Orion’s trajectory, placing it into a stable high Earth orbit. The new orbit aligns with the spacecraft’s planned path for departure toward the Moon.
Engineers design these burns to test propulsion precision under real mission conditions. Small timing or thrust variations can significantly alter a spacecraft’s trajectory over long distances.
Following the maneuver, astronauts returned to a rest cycle lasting about four and a half hours, part of a schedule structured to balance workload and recovery during the mission’s early phase.

Translunar injection burn timing and mission approval process
Attention now shifts to the next and more consequential maneuver, the translunar injection burn.
Mission management teams are scheduled to meet later in the day to assess spacecraft health, propulsion data, and navigation accuracy. Their approval is required before proceeding.
If cleared, the translunar injection burn is set for 7:49 p.m. Eastern Time. The maneuver will last five minutes and 49 seconds and is expected to increase Orion’s velocity by 1,274 feet per second.
That acceleration would push the spacecraft out of Earth orbit and onto a trajectory toward the Moon. It would mark the first time humans leave low Earth orbit since the Apollo era, which concluded with the final Moon mission in 1972.
Flight controllers will monitor engine performance and guidance systems throughout the burn. Navigation data must remain within tight tolerances to ensure Orion stays aligned with its intended path.
The Artemis II mission is designed as a test flight, but each milestone carries operational weight. With the perigee burn complete, the next decision point will determine whether the crew begins its journey beyond Earth orbit.
NASA confirmed the Artemis II crew resolved a toilet system fault aboard the Orion spacecraft on April 2 while in Earth orbit. The issue, first detected as a blinking fault light on April 1, was addressed through coordinated troubleshooting with mission control in Houston. The fix comes ahead of a scheduled perigee raise burn, a maneuver that will adjust Orion’s orbit for future deep space operations.
A minor but essential system aboard NASA’s Artemis II spacecraft briefly drew attention this week. It was not propulsion or navigation. It was the toilet.
Astronauts aboard Orion, the capsule named Integrity, reported a blinking fault light tied to the waste management system on April 1. Within hours, engineers on the ground and the crew in orbit worked through the problem together. By the next mission update, the system was back to normal operation.
The episode highlights how even routine spacecraft functions demand precision during crewed missions led by the National Aeronautics and Space Administration.
Orion spacecraft toilet issue and in-flight troubleshooting
The issue first surfaced ahead of a planned apogee raise burn, when the crew noticed a blinking fault indicator linked to Orion’s toilet system. Such warning signals are designed to flag irregularities early, even when the system continues functioning.
NASA’s mission control team at the Johnson Space Center in Houston began reviewing telemetry immediately. Engineers assessed system data while communicating directly with the astronauts to isolate the cause.
The troubleshooting process involved both software diagnostics and procedural checks inside the spacecraft. The agency did not report any hardware damage or safety risk tied to the issue.
By April 2, NASA confirmed that normal functionality had been restored. The resolution ensured that one of the spacecraft’s life-support subsystems remained fully operational as the mission continued.
Waste management systems in microgravity rely on airflow, pressure control, and precise mechanical components. Even minor anomalies require immediate attention, as they can affect crew comfort and long-duration mission readiness.

NASA
Perigee raise burn timing and mission trajectory planning
With the issue resolved, the Artemis II crew is preparing for the next major step in the mission timeline. The perigee raise burn is scheduled after a planned rest period.
Perigee refers to the lowest point of a spacecraft’s orbit around Earth. Raising it changes the orbital shape, making it more stable and better suited for future maneuvers.
This burn follows an earlier apogee raise maneuver, which increased Orion’s highest orbital point. Together, the two burns define the spacecraft’s initial orbit and test its propulsion system under operational conditions.
NASA scheduled a four-hour rest period for the crew before the maneuver. Astronauts are set to wake at 7 a.m. Eastern Time on April 2 to begin preparations. After completing post-burn procedures, they will return to a second sleep cycle later in the morning.
The sequence reflects the structured rhythm of human spaceflight, where operational tasks alternate with carefully timed rest to maintain performance.
The Artemis II mission continues to build toward its broader objective: validating systems for future missions that will carry astronauts beyond Earth orbit and toward the Moon.
NASA’s Artemis II crew completed a proximity operations test on April 2, maneuvering the Orion spacecraft near a detached rocket stage in Earth orbit. The demonstration, lasting about 70 minutes, tested manual control systems and gathered data critical for future lunar missions. The crew now prepares for a perigee raise burn, while engineers continue troubleshooting a minor onboard toilet system issue.
The astronauts aboard NASA’s Artemis II mission spent part of April 2 guiding their spacecraft through a tightly choreographed exercise hundreds of miles above Earth.
Inside Orion, the capsule named Integrity, the crew manually steered within close range of a discarded rocket stage, testing how precisely humans can control the spacecraft in space. The task lasted just over an hour. It marked one of the first hands-on demonstrations of Orion’s maneuverability under crew control.
The exercise is part of a broader effort by the National Aeronautics and Space Administration (NASA) to validate systems before sending astronauts farther into deep space, including eventual missions to the Moon under the Artemis program.
The proximity operations demonstration centered on Orion’s ability to approach and move away from another object in orbit. For this test, the crew used the detached interim cryogenic propulsion stage, or ICPS, as a reference target.
The ICPS, a temporary upper stage used during launch, had already separated from the spacecraft. It remained nearby long enough for the astronauts to conduct controlled approach and retreat maneuvers.
During the roughly 70-minute session, the crew adjusted Orion’s position repeatedly, testing navigation, thruster response, and onboard guidance systems. These maneuvers simulate conditions required for future missions that may involve docking or operating near other spacecraft.
At the end of the exercise, Orion executed an automated departure burn, increasing its distance from the ICPS. The stage is scheduled to perform a disposal burn, sending it into Earth’s atmosphere over a remote Pacific region, according to NASA mission updates.
The demonstration provides engineers with real-time data on how Orion performs under manual control, a capability considered essential for complex operations during lunar missions.
Alongside the crewed mission, four small satellites known as CubeSats launched as secondary payloads aboard the Space Launch System (SLS).
CubeSats are compact, shoebox-sized spacecraft designed for targeted scientific experiments. They will deploy after the Orion stage adapter separates from the main spacecraft.
Each satellite carries a distinct research objective:
ATENEA, developed by Argentina’s national space agency, focuses on radiation shielding and communication systems in high Earth orbit.
Space Weather CubeSat-1, built by the Saudi Space Agency, will measure solar radiation, X-rays, and magnetic field activity.
TACHELES, from the German Aerospace Center, is testing electrical systems for future lunar logistics vehicles.
K-Rad Cube, developed by the Korea AeroSpace Administration, will study radiation effects across the Van Allen belts, regions of charged particles surrounding Earth.
The CubeSat deployments expand the mission’s scientific output, offering data on space weather and radiation environments that astronauts may encounter during longer missions.

Perigee raise burn planned as engineers monitor onboard issue
Attention now shifts to the next key maneuver, the perigee raise burn, scheduled after the crew’s rest period.
Perigee refers to the lowest point in a spacecraft’s orbit around Earth. Raising it adjusts the shape of the orbit and prepares Orion for later phases of the mission, including potential translunar trajectories.
The maneuver follows an earlier apogee raise burn, which increased the spacecraft’s highest orbital point. Together, these burns define Orion’s initial orbital path and test propulsion performance under operational conditions.
Before the next burn, the crew completed routine spacecraft checks. During a systems review, they reported a blinking fault light in the onboard toilet system.
NASA ground teams are analyzing the data and working with the crew to diagnose the issue. No broader system impacts have been reported in official updates.
After a scheduled four-hour rest period, the astronauts are set to wake at 7 a.m. Eastern Time on April 2 to prepare for the maneuver. The timeline includes post-burn activities followed by another sleep cycle later in the morning.
The sequence of tests, adjustments, and troubleshooting reflects the mission’s dual purpose: demonstrating Orion’s readiness for deep space while gathering operational data from a live crewed environment.
A new study published on April 2026 finds that Saturn has an asymmetrical magnetic field unlike Earth, based on six years of data from the Cassini–Huygens mission. Researchers led by institutions including University College London found that Saturn’s magnetic cusp shifts due to its rapid rotation and plasma from its moon Enceladus. The findings offer new insight into how magnetospheres behave on fast-spinning gas giants and could shape future missions to Saturn.
A region of space where charged particles slip into a planet’s atmosphere has revealed a key difference between Earth and Saturn.
Researchers studying Saturn’s magnetic field found that its protective bubble, known as the magnetosphere, is not evenly shaped. Instead, it appears skewed to one side, a departure from the more symmetrical magnetic structure observed around Earth.
The findings come from a study published in Nature Communications, based on data gathered by the Cassini spacecraft over six years between 2004 and 2010.
Cassini Data Maps Saturn’s Shifted Magnetic Entry Point
The study focused on Saturn’s “cusp,” the region where magnetic field lines bend and allow solar wind particles to funnel into the planet’s atmosphere.
Using measurements from Cassini’s Magnetometer and Plasma Spectrometer instruments, researchers identified 67 instances where the spacecraft passed through this cusp region.
On Earth, the cusp typically aligns around noon when viewed relative to the Sun. On Saturn, the team found it most frequently appeared between 13:00 and 15:00, indicating a consistent shift to one side.
This displacement suggests that Saturn’s magnetosphere is being pulled in a particular direction rather than remaining evenly balanced.
Fast Rotation And Plasma Drive The Asymmetry
Scientists attribute this asymmetry to two main factors: Saturn’s rapid rotation and the dense plasma environment surrounding the planet.
A day on Saturn lasts about 10.7 hours, significantly faster than Earth’s 24-hour cycle. This rapid spin generates strong rotational forces that influence the planet’s magnetic field.
At the same time, Saturn is surrounded by a cloud of ionised gas, or plasma, much of which originates from its moon Enceladus. The moon releases water vapor through icy plumes, which becomes ionised and contributes to the magnetospheric environment.
Together, the fast rotation and heavy plasma appear to drag the magnetic field lines in one direction, creating the observed lopsided structure. Researchers noted that further simulations are required to confirm this mechanism.
Professor Andrew Coates of University College London’s Mullard Space Science Laboratory said the cusp plays a central role in understanding the system.
“The cusp is the place where the solar wind can slip directly into the magnetosphere. Knowing the location of Saturn’s cusp can help us better understand and map the whole magnetic bubble,” he said.
Implications For Future Missions And Search For Life
The findings come at a time when scientific interest in Saturn and its moons is growing, particularly due to Enceladus.
The icy moon contains a subsurface ocean and emits plumes that have drawn attention as a potential environment for microbial life. It is also a proposed destination for a future mission by the European Space Agency planned for the 2040s.
“A better understanding of Saturn’s environment is especially urgent now as plans for our return to Saturn and its moon Enceladus start to be developed,” Coates said.
“This time we will look for evidence of habitability and for potential signs of life.”
The study also supports a broader theory about how magnetospheres behave on large, fast-spinning planets.
Professor Zhonghua Yao of the University of Hong Kong said differences between Earth and Saturn point to a shared underlying process governing interactions with solar wind across planets.
Lead author Yan Xu of the Southern University of Science and Technology added that combining spacecraft data with simulations helped reveal how rotation and plasma shape the global magnetic structure.
A Broader Pattern Across Gas Giants
The research suggests that Saturn’s magnetosphere may resemble that of Jupiter more closely than Earth’s, despite all three planets being exposed to the same solar wind.
This indicates that internal planetary dynamics, such as rotation speed and plasma sources, can outweigh solar wind in shaping magnetic environments on gas giants.
The results provide a framework for studying other planetary systems, including exoplanets, where similar forces may be at play.
As researchers continue to analyze Cassini’s legacy data, Saturn’s magnetic field is offering a deeper view into how planetary systems function beyond Earth.
NASA confirmed the Artemis II crew completed the apogee raise burn on April 2, increasing Orion’s orbital high point. The mission now transitions toward a proximity operations demonstration that will test manual spacecraft control near another object. Engineers continue to monitor a minor onboard system issue as the crew prepares for the next phase.
The spacecraft climbed higher. The mission grew more precise.
The National Aeronautics and Space Administration confirmed that Artemis II successfully executed its apogee raise maneuver, a key step in refining the Orion spacecraft’s orbit around Earth. The burn, powered by the interim cryogenic propulsion stage’s RL10 engine, increased the spacecraft’s highest orbital point and aligned it for upcoming tests.
The maneuver follows earlier orbital adjustments and forms part of a carefully sequenced plan to prepare Orion for operations beyond low Earth orbit. NASA officials said the spacecraft remains in stable condition, with power generation and thermal systems operating within expected limits.
Artemis II apogee raise burn and orbit shaping
The apogee raise burn works in tandem with the previously completed perigee adjustment. Together, these maneuvers define the shape and altitude of Orion’s orbit, ensuring the spacecraft is positioned correctly for subsequent demonstrations and trajectory changes.
Mission controllers at Johnson Space Center continue to track performance data, confirming that propulsion and navigation systems responded as expected.
Ahead of the burn, astronauts also began configuring the spacecraft for sustained operations in orbit. That included routine system checks such as evaluating the onboard toilet system. During that procedure, the crew reported a blinking fault light, which engineers are now analyzing.
NASA has not indicated that the issue affects mission safety, but teams are working with the crew to identify its cause and resolve it.

Proximity operations demonstration and manual control testing
The next phase of Artemis II will focus on proximity operations, a critical test of Orion’s ability to maneuver near another spacecraft.
The demonstration will use the detached upper stage of the Space Launch System as a reference target. Astronauts will guide Orion, named Integrity, through a series of controlled movements to evaluate how the spacecraft performs under manual control.
Before the maneuver begins, communications will transition from NASA’s Near Space Network to the Deep Space Network, systems that support spacecraft from launch through deep-space operations.
During the approximately 70-minute exercise, Orion will approach the upper stage to within about 300 feet before pausing. The crew will then take manual control, using onboard hand controllers to make precise adjustments and assess responsiveness.
At a closer range of roughly 30 feet, astronauts will evaluate the spacecraft’s fine handling capabilities. These maneuvers will rely on the reaction control system thrusters located on Orion’s European-built service module.
NASA said the demonstration also includes an automated backflip maneuver, allowing Orion to reorient and face the target stage. The test will generate detailed data on navigation and control systems, including measurements from the spacecraft’s docking camera.
These data points are expected to inform future missions that require rendezvous and docking in lunar orbit, where traditional GPS systems are not available.
Preparing for future lunar operations
At the conclusion of the demonstration, Orion will execute an automated departure burn to safely distance itself from the upper stage. The stage will then perform a disposal maneuver, re-entering Earth’s atmosphere over a remote region of the Pacific Ocean.
NASA said the spacecraft’s systems remain stable as the crew transitions into this next phase. Solar arrays continue to generate power, and environmental conditions inside Orion remain within predicted ranges.
Public interest in the mission’s technical milestones remains high. “This is the kind of test that proves whether astronauts can really control the vehicle in deep space,” wrote Reddit user LunarOpsWatcher in a post with more than 1,100 upvotes, highlighting the importance of manual maneuvering capabilities.
Artemis II is designed as a test mission, but each milestone carries implications for future exploration. The proximity operations demonstration, in particular, addresses a key requirement for sustained human activity beyond Earth orbit.
With the apogee burn complete, Orion now moves into one of its most intricate tests yet.
NASA confirmed the Artemis II crew completed a perigee raise maneuver on April 2, refining Orion’s orbit around Earth. A brief communications loss occurred shortly after the burn but was quickly resolved with no reported impact on crew safety. The agency will hold a press conference from Kennedy Space Center as the mission prepares for its next orbital milestone.
A routine engine burn sharpened Artemis II’s orbit. Minutes later, mission control lost contact. Then the signal came back.
The National Aeronautics and Space Administration said the Orion spacecraft successfully completed its perigee raise maneuver, one of the key early steps in shaping its path around Earth. The burn used the interim cryogenic propulsion stage’s RL10 engine to lift the spacecraft’s lowest orbital point, refining its trajectory for later mission phases.
The maneuver followed earlier orbital adjustments and forms part of a sequence designed to prepare Orion for operations beyond low Earth orbit. NASA officials said the burn occurred as planned, with precise timing required to achieve the desired orbital change.
Artemis II perigee raise burn and orbital adjustments
The perigee raise maneuver increases the spacecraft’s minimum altitude during its orbit. Along with a separate apogee raise burn, which affects the highest orbital point, these adjustments create a stable and elongated orbit suitable for further testing.
NASA said these burns are critical in preparing Orion for a planned high Earth orbit phase lasting about 23.5 hours. During that period, astronauts and ground teams will conduct system checkouts before committing to the next stage of the mission.
The work is coordinated through mission control at Johnson Space Center, where engineers track propulsion performance, navigation data, and onboard systems in real time.

NASA
Brief communication dropout under review
Shortly after completing the burn, ground teams experienced a temporary loss of communications with the spacecraft. NASA said controllers were unable to receive data from Orion or the crew for a brief period.
The interruption resolved quickly. Astronauts reported that they continued to hear communications from the ground throughout the event, indicating that onboard systems remained functional.
NASA said engineers are reviewing telemetry to determine the cause of the dropout. The agency has not indicated any impact on mission safety or trajectory.
Such communication gaps, while uncommon, are treated as high-priority review items during test missions. Artemis II, as a crewed test flight, is designed to expose and evaluate system behavior under real operating conditions.
NASA press conference and mission leadership
NASA will hold a post-launch press conference at 8 p.m. EDT from the Kennedy Space Center to provide further updates.
Scheduled participants include NASA Administrator Jared Isaacman, Associate Administrator Amit Kshatriya, Lori Glaze, who serves as acting associate administrator for the Exploration Systems Development Mission Directorate, and Norm Knight, director of the Flight Operations Directorate.
The briefing is expected to address the completed maneuver, the communication anomaly, and upcoming mission steps.
Public attention remains fixed on the mission’s progress. “Even a small signal loss gets people nervous, but that’s why they test,” wrote Reddit user SpaceTrackLive in a post that drew more than 900 upvotes, reflecting cautious optimism among spaceflight observers.
Next milestone: apogee raise burn and system checks
The next major step for Artemis II is the apogee raise maneuver. This burn will increase the highest point of Orion’s orbit, complementing the earlier perigee adjustment.
Together, these orbital changes define the spacecraft’s path before it transitions into high Earth orbit operations. NASA said this phase will allow for extended system verification and crew activity in preparation for the mission’s later trajectory toward the Moon.
Engineers view these incremental milestones as essential. Each burn, test, and anomaly review contributes to a broader goal: confirming that Orion can safely carry astronauts through deep space and back.
For now, Artemis II continues to move step by step. One maneuver completed, one anomaly under review, and another burn on the horizon.
Astronauts aboard NASA’s Artemis II mission completed a key proximity operations test on April 2 while orbiting Earth. The maneuver involved controlled movements around a detached rocket stage to evaluate spacecraft handling. With CubeSat deployments ahead and a minor onboard system issue under review, the crew is now preparing for a perigee raise burn to refine Orion’s orbit.
A shoebox-sized satellite deployment and a blinking fault light now share space in NASA’s latest Moon mission update.
The National Aeronautics and Space Administration confirmed that astronauts aboard Artemis II have completed one of the mission’s earliest and most technical tests. The crew piloted the Orion spacecraft, named Integrity, through a series of close-range maneuvers around a detached rocket stage, simulating scenarios required for future docking and deep-space operations.
The 70-minute exercise marked the mission’s proximity operations demonstration. Using the interim cryogenic propulsion stage, or ICPS, as a reference point, astronauts conducted controlled approach and retreat sequences to assess manual navigation capabilities in orbit.
At the end of the test, Orion executed an automated departure burn to safely distance itself from the stage. NASA said the ICPS will later perform a disposal burn, re-entering Earth’s atmosphere over a remote part of the Pacific Ocean.

NASA
Orion proximity operations test and orbital maneuver plan
The proximity operations test is central to Artemis II’s role as a proving mission. Unlike future lunar landings, this flight focuses on validating systems and crew performance under real spaceflight conditions.
NASA officials said the demonstration provided critical data on how Orion behaves during manual piloting near another object. These conditions are expected to be essential for future missions involving docking, assembly, or logistics operations in lunar orbit.
The crew now turns to the next phase of orbital adjustments. After completing an earlier apogee raise maneuver, mission controllers are preparing for a perigee raise burn. This engine firing will increase the lowest point of Orion’s orbit around Earth, refining its trajectory for eventual translunar injection.
The sequence of burns shapes the spacecraft’s path before it departs Earth’s gravitational influence. These adjustments are necessary to ensure precision as the mission transitions toward its planned lunar flyby.
CubeSat deployments expand international science efforts
Alongside the crewed mission, Artemis II is carrying four CubeSats, compact satellites designed for scientific research and technology demonstrations.
These payloads, housed within the Space Launch System adapter, will deploy after separation from Orion. Each satellite represents an international collaboration and targets a different aspect of space science.
Argentina’s ATENEA CubeSat will study radiation shielding and communication systems. The Saudi Space Agency’s Space Weather CubeSat-1 will measure solar radiation and magnetic fields. Germany’s TACHELES mission will test components for future lunar logistics systems. South Korea’s K-Rad Cube will analyze radiation exposure and its biological effects across the Van Allen belts.
NASA describes CubeSats as small but versatile tools that can extend mission science at relatively low cost. Their deployment during Artemis II adds a layer of experimentation beyond the primary crewed objectives.
Toilet system issue under review during mission operations
Amid the technical milestones, engineers are also tracking a minor onboard issue.
During routine spacecraft configuration checks, the crew reported a blinking fault light in Orion’s toilet system. Mission control teams at Johnson Space Center are analyzing telemetry and working with astronauts to troubleshoot the problem.
NASA has not indicated that the issue poses a risk to crew safety or mission objectives. Such anomalies are not uncommon during test flights, where systems are evaluated under operational conditions for the first time.
The crew’s schedule includes carefully timed rest periods between mission activities. After a four-hour sleep cycle, astronauts are set to wake at 7 a.m. EDT to prepare for the upcoming burn, before returning to rest later in the day.
Public reaction to the update has reflected both enthusiasm and curiosity about the mission’s technical details. “It’s fascinating to see them actually test manual flying like this,” wrote Reddit user OrbitalWatcher, in a post that drew more than 1,200 upvotes, noting that such maneuvers are rarely visible to the public.
Preparing for deeper space operations
Artemis II continues to function as a systems validation mission, bridging the gap between uncrewed tests and future lunar landings.
Each milestone, from proximity operations to orbital burns, contributes to a broader objective. NASA aims to confirm that Orion and its supporting systems can reliably carry astronauts beyond low Earth orbit and back.
The upcoming perigee raise burn represents another step in that process. Once completed, it will help finalize the spacecraft’s orbit before the mission advances toward its lunar trajectory.
For engineers and mission planners, these incremental steps are essential. They provide the data needed to support more complex operations in future Artemis missions, including sustained human presence on the Moon.
Another investigation that forms the structure of massive craters on asteroid 16 Psyche is providing new perspectives on one of the most persistent mysteries of the Solar System, whether the metallic object is the open core of an unsuccessful planet or a complex of debris formed during numerous collisions.
The scientists in the Lunar and Planetary Laboratory of the University of Arizona are the researchers who conducted the study, which was published in JGR Planets, and dedicated to the possibility of unlocking the inner composition of Psyche due to a large impact basin located near the north pole of the asteroid. The results will likely inform the interpretation of the data of the NASA Psyche space probe, which will visit the asteroid in the year 2029.
The largest known metal-rich asteroid is psyche, which is found in the prime asteroid belt separating mars and Jupiter and is one of the heaviest bodies found in the area. Its bizarre structure has been a long-standing puzzle to scientists, and rival theories have proposed that it might be the rocky and metallic inertia of an early planet, or of violent impact that caused the mixing of metals and rock over time.
To experiment with such situations, scientists ran high-speed crashes on a 3-D model of Psyche which was how a crater similar to 30 miles across and three miles deep was formed. The differing impact conditions and internal structures allowed the team to come up with predictions regarding the way various compositions would form the resulting crater and the surrounding debris.
According to the simulations, porosity, which is the empty space in the asteroid, is an important factor that affects the crater formation. This is different to solid planetary bodies, most asteroids are loose or fractured and thus can absorb impact energy in a different manner. Impacts in more porous structures will create deeper and steeper craters and less material ejected on the surface.
Asteroid layered metallic core
There were two main models of the interior of Psyche tested in the study: the asteroid is layered reaching a dense metallic core and thin rocky mantle, and the second one is that the metal and silicate materials are evenly intermingled. Although both scenarios could result in the measured crater sizes, each scenario created a different ejecta pattern and internal compression pattern.
These variations, according to researchers, may turn out to be important suggestions when there would be direct observations. Equipments in the Psyche spacecraft will capture the surface composition of the asteroid, gravity and magnetic field, an assessment of the difference in density that could have occurred due to impact in the past.
Scientists compare the research to the reconstruction of a process that has been abandoned long ago based on its remains. Through surface studies of craters and patterns of debris those studying them hope to be able to determine the internal composition of a body that might be able to tell us about the very earliest phases of planetary formation.
Origin of Psyche
The theory of the origin of Psyche has more far-reaching consequences in the field of planetary science. The discovery of the asteroid as an exposed core would give an opportunity to study processes that formed rocky planets such as Earth processes that are otherwise not reachable since planetary cores are buried deep within thick mantles.
Another theme addressed in the study is the increased importance of advanced simulations in space mission preparation. Predicting tests set in advance before the arrival of the spacecraft, researchers want to speed up the analysis of the information once the real-time stream of information arrives.
Psyche mission, which was initiated by Arizona State University and is supported by NASA Jet Propulsion Laboratory and other organizations belongs to NASA Discovery Program. By the time the spacecraft arrives at its destination towards the end of this decade, scientists are hopeful that it will provide the first close-up view of a metallic world – and possibly end a two hundred plus century long debate.
