NASA’s Perseverance Rover Gets the Dirt on Mars

The mission’s first two samples of regolith – broken rock and dust – could help scientists better understand the Red Planet and engineers prepare for future missions there. NASA’s Perseverance rover snagged two new samples from the Martian surface on Dec. 2 and 6. But unlike the 15 rock cores collected to date, these newest samples came from a pile ...

Oxygen is the key substance for life and one of the most abundant elements in the Earth. However, it’s still unknown whether oxygen is present and in which form in the inner core with extreme high pressure and temperature conditions, and almost composed of pure iron. Scientists co-led by Dr. Jin Liu from HPSTAR (the Center for High Pressure Science ...

Edward Stone: 50 Years at NASA ends, but his brainchild Voyager’s Project goes on

Edward Stone

Stone’s remarkable tenure on NASA’s longest-operating mission spans decades of historic discoveries and firsts. Edward Stone has retired as the project scientist for NASA’s Voyager mission a half-century after taking on the role. Stone accepted scientific leadership of the historic mission in 1972, five years before the launch of its two spacecraft, Voyager 1 and Voyager 2. Under his guidance, the Voyagers explored the four ...

NASA’s Swift, Fermi missions detect exceptional cosmic blast

NASA

Astronomers around the world are captivated by an unusually bright and long-lasting pulse of high-energy radiation that swept over Earth Sunday, Oct. 9. The emission came from a gamma-ray burst (GRB) – the most powerful class of explosions in the universe – that ranks among the most luminous events known. On Sunday morning Eastern time, a wave of X-rays and ...

NASA: Are you in an area of Lucy then take a photograph, post it to social media

Lucy Spacecraft

On Oct. 16, at 7:04 a.m. EDT, NASA’s Lucy spacecraft, the first mission to the Jupiter Trojan asteroids, will skim the Earth’s atmosphere, passing a mere 220 miles (350 kilometers) above the surface. By sling-shotting past Earth on the first anniversary of its launch, Lucy will gain some of the orbital energy it needs to travel to this never-before-visited population ...

No Picnic in the Clouds! It’s JPL aerobot

JPL’s Venus Aerial Robotic Balloon Prototype Aces Test Flights A scaled-down version of the aerobot that could one day take to the Venusian skies successfully completed two Nevada test flights, marking a milestone for the project. The intense pressure, heat, and corrosive gases of Venus’ surface are enough to disable even the most robust spacecraft in a matter of hours. ...

After 70 years, Jupiter moves closest to Earth on Sept 26

Jupiter is set to make its closest approach to Earth in the last 70 years and on September 26, stargazers can expect an excellent view when the giant planet reaches opposition. From the viewpoint of Earth’s surface, opposition happens when an astronomical object rises in the east as the Sun sets in the west, placing the object and the Sun ...

Where do high-energy particles that endanger satellites, astronauts, airplanes come from?

For decades, scientists have been trying to solve a vexing problem about the weather in outer space: At unpredictable times, high-energy particles bombard the earth and objects outside the earth’s atmosphere with radiation that can endanger the lives of astronauts and destroy satellites’ electronic equipment. These flare-ups can even trigger showers of radiation strong enough to reach passengers in airplanes ...
