Artemis I, the first integrated test of NASA’s Space Launch System (SLS) rocket, Orion spacecraft, and the ground equipment, is scheduled for liftoff from Kennedy Space Center in Florida at 2:17 p.m. EDT on Saturday, September 3. For the following attempt, a window of two hours has been allotted for liftoff.


To prepare for a crewed flight test and eventual human lunar exploration, Artemis I is conducting an uncrewed voyage around the Moon.

NASA’s website, mobile app, and television will all provide live coverage of the events:

After a scheduled 2.5 hour built-in pause begins at 4:37 a.m. on Saturday, September 3, the launch countdown will restart.

Officials called off the initial launch attempt on August 29 after controllers had trouble cooling down all four of the RS-25 engines. One engine in particular was running hotter than the others. To fix the problems, teams are currently collecting data, reviewing current processes, and testing available hardware.

On-site media who have been accredited will have access to a limited number of seats in the Kennedy auditorium on a first-come, first-served basis. Accreditation for on-site press coverage of this launch has closed.

RSVP to no later than two hours before the start of each briefing if you’re a member of the media and would like to participate via telephone.

Those in the media and the general public can tweet their inquiries using the hashtag #Artemis. The NASA “V” circuits (accessible via the numbers 321-867-1220, -1240, -1260, or 7135) will broadcast the press conferences in audio-only form.
