Space The agency had worked to test the system that powers liquid hydrogen on September 17, but the date for that cryogenic test has now been pushed back to September 21, NASA noted on its Artemis blog.
“The updated dates represent careful consideration of several logistical topics, including the added value of having more time to prepare for the cryogenic demonstration test, and subsequently more time to prepare for launch. also allow managers to ensure teams have enough rest and to replenish cryogenic propellant supplies,” NASA explained in the blog post.
The Sept. 21 test will include an engine purge test, according to the agency. The mission team canceled the first launch attempt of Artemis I on August 29, largely due to a problem with the engine purge, which cools the engines for launch, which officials say , was due to a faulty sensor.
The September 27 launch window is 70 minutes long – shorter than the 120 minute window available on September 23.
The officials at NASA said the space agency continues to provide information to the Eastern Range, which must grant a waiver to allow the rocket to remain on the launch pad.
“NASA continues to follow the Eastern Range review process of the agency’s request for an extension of the current testing requirement for the Flight Shutdown System and provides additional information and data as needed. In parallel, the agency is continuing preparations for the cryogenic demonstration test and potential launch opportunities, if the application is approved,” the blog said.
