Artemis III is planned to be the first crewed Moon landing mission of the Artemis program and the first crewed flight of the Starship HLS lander. Artemis III is planned to be the second crewed Artemis mission and the first crewed lunar landing since Apollo 17 in December 1972. As of December 2024[update], NASA officially expects Artemis III to launch no earlier than mid-2027 due to heat shield issues on Orion and valve problems in the spacecraft's life support system.
In August 2023, due to delays in the development of Starship, NASA officials expressed an openness to flying Artemis III without a crewed landing. In this case, the mission may become a crewed visit to the Lunar Gateway. In April 2024, it was reported that alternative mission options being internally evaluated by NASA include a test of docking between Orion and Starship HLS in low Earth orbit.
