NASA's canceled Artemis hardware contracts reached $5.9 billion, audit finds
NASA announced a major shakeup to its Artemis plans earlier this year at its "Ignition Day" event, restructuring its mission goals in order to streamline the return of astronauts to the lunar surface and simplify the architecture needed to get them there. Most notably, the program's first crewed moon landing was shifted from Artemis 3 to Artemis 4, and upgraded variations of NASA's Space Launch System (SLS) rocket were abandoned for a single uniform design. The Gateway space station planned for lunar orbit was also canceled in favor of a stronger focus on establishing a base on the moon's surface.
