Artemis I, is a planned uncrewed Moon-orbiting mission, the first spaceflight in NASA's Artemis program.
Artemis I is the first spaceflight in NASA's Artemis program, and the first flight of the agency's Space Launch System (SLS) rocket and the complete Orion spacecraft.
The Artemis program is a robotic and human Moon exploration program led by the United States space agency NASA, and involving three other partner agencies: ESA, JAXA and CSA.
The Artemis program will reestablish a human presence on the Moon for the first time since the Apollo 17 mission in 1972.
The major components of the program are the Space Launch System (SLS), Orion spacecraft, Lunar Gateway space station and the commercial Human Landing Systems, including Starship HLS.
The Artemis program is a collaboration of space agencies and companies around the world, bound together via the Artemis Accords and supporting contracts.
Twenty one countries have signed the accords, including US Space Agency and agencies from Canada, Japan, and the United Kingdom and emerging space powers such as Brazil, South Korea, and the United Arab Emirates.
It is formerly known as Exploration Mission-1 (EM-1), the mission was renamed following the creation of the Artemis program.
On 29 August 2022, the first launch attempt was made, but cancelled due to a faulty reading on a redundant sensor. The problems forcing a halt to the countdown and postponement of the uncrewed flight.
NASA announced that it would scheduled to launch the next attempt on 3 September 2022 for a second try, hoping to have remedied engineering problems that foiled the initial countdown five days earlier.
The Orion spacecraft will spend approximately three weeks in space, including six days in a distant retrograde orbit around the Moon. If 2nd attempt successfully launch, then the mission will last 37 days.
