NASA is targeting 2:17 p.m. EDT on Saturday, Sept. 3, for the launch of Artemis I, the first integrated test of NASA’s Space Launch System (SLS) rocket, Orion spacecraft, and the ground systems at the agency’s Kennedy Space Center in Florida. There is a two-hour launch window for the next attempt.
The Artemis I flight test is an uncrewed mission around the Moon that will pave the way for a crewed flight test and future human lunar exploration as part of Artemis.
Live coverage of events will air on NASA Television, the NASA app, and the agency’s website at:
The launch countdown will resume Saturday, Sept. 3, at the opening of a planned 2.5 hour built in hold, which will begin at 4:37 a.m.
Managers waved off the first launch attempt Aug. 29 when launch controllers were unable to chill down the four RS-25 engines, with one engine showing higher temperatures than the other engines. Teams currently are analyzing data, updating procedures, and checking out hardware to address the issues.
A limited number of seats inside the auditorium at Kennedy will be available to on-site journalists previously credentialed on a first-come, first-served basis. The deadline has passed for media accreditation for in-person coverage of this launch.
To participate by telephone, media must RSVP no later than two hours before the start of each briefing to: ksc-newsroom@mail.nasa.gov.
Media and members of the public may also ask questions on social media using #Artemis. Audio only of the news conferences will be carried on the NASA “V” circuits, which may be accessed by dialing 321-867-1220, -1240, -1260 or -7135.
