Lack of SLS rockets limit NASA Artemis manifest

Published by NASASpaceflight on 09/26/2023

NASA and its advisory bodies remain concerned about the low flight rate planned for its crewed Orion spacecraft and Space Launch System (SLS) rocket, but the space agency doesn’t have enough vehicles to fly more often this decade. Hardware to launch only two more SLS vehicles is available until development of the Exploration Upper Stage (EUS) upgrade is completed, which isn’t expected to be ready to launch on Artemis IV until late 2028 at the earliest.
