The upper stage for NASA’s SLS (Space Launch System) rocket that will power the agency’s Artemis III mission and send astronauts on to the Moon for a lunar landing arrived at the Cape Canaveral Space Force Station Poseidon Wharf in Florida on Aug. 9, 2023. Known as the SLS ICPS (interim cryogenic propulsion stage), it will undergo final checkouts by contractors Boeing and ULA (United Launch Alliance) at ULA’s facilities before it is delivered to NASA’s nearby Kennedy Space Center.
