The Artemis program is a human and robotic Moon exploration program led by NASA. If successful, the Artemis program will reestablish human presence on the Moon. The last presence there was the Apollo 17 mission in 1972. The major components of the program are the Space Launch System, 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. The long-term vision of the Artemis program is to establish a permanent base camp on the Moon and facilitate human missions to Mars.
The Artemis program was formally established in 2017 during the Trump administration; however, many of its components such as the Orion spacecraft were developed during the previous Constellation program (2005–2010) and after its cancellation. The Space Launch System and Orion's first launch was originally set in 2016, but it has been renamed the Artemis 1 mission and scheduled to launch in 2022 with robots and dummies aboard. According to plan, the crewed Artemis 2 launch will take place in 2024, Artemis 3 crewed lunar landing in 2025, Artemis 4 docking with the Lunar Gateway in 2027 and future yearly landing on the Moon. However, the program's cost and timeline are likely to be overran and delayed, due to NASA's improper management of contractors.
