The Apollo Program delivered 12 American astronauts to the surface of the Moon. But that program ended in 1972, and since then, no human beings have visited. But Artemis will change that. And instead of just visiting the Moon, Artemis’ aim is to establish a longer-term presence on the Moon. That requires more complexity than Apollo did. Astronauts will need to transfer between vehicles.
All of that activity requires a reliable spacecraft docking system.
SpaceX and NASA recently performed full-scale qualification testing of the docking system that will connect SpaceX’s Starship Human Landing System (HLS) with Orion and later Gateway in lunar orbit during future crewed Artemis missions. Based on the flight-proven Dragon 2 active docking system, the Starship HLS docking system will be able to act as an active or passive system during docking.
