NASA has outlined revised operations for the crewed lunar landers being developed by SpaceX and Blue Origin. Artemis III is now intended to demonstrate rendezvous and docking between Orion and test versions of both systems in low Earth orbit. For subsequent lunar missions, each provider must complete an uncrewed demonstration of its crewed lander before NASA certification. The agency is targeting a 2028 return of astronauts to the lunar surface, but has not selected the provider for the first landing. [S1]
