NASA Television will provide live coverage of the upcoming Artemis I cryogenic demonstration test on NASA TV beginning at 7:15 a.m. EDT or 4.30 pm IST on Wednesday, Sept. 21.
The demonstration test will allow teams to confirm the repair to a hydrogen leak seen during an early September Artemis I launch attempt, evaluate updated propellant loading procedures, and conduct additional evaluations. The demonstration will conclude when the objectives for the test have been met.
NASA remains on track for an Artemis I cryogenic demonstration test.In the days since the previous launch attempt, teams have analyzed the seals that were replaced on an interface for the liquid hydrogen fuel line between the Space Launch System (SLS) rocket and the mobile launcher and adjusted procedures for loading cryogenic, or supercold, propellants into the rocket. Engineers identified a small indentation found on the eight-inch-diameter liquid hydrogen seal that may have been a contributing factor to the leak on the previous launch attempt.

During the test, teams will load propellants into both the core stage and upper stage tanks, and Orion and the SLS boosters will remain unpowered. Meteorologists currently predict favorable weather for the test with a 15% chance of lightning within 5 nautical miles of the area, which meets criteria required for the test, and will continue to monitor expected conditions.
