NASA has approved its Moon rocket for a potential April launch with four astronauts after completing repairs. The Artemis II mission aims for humanity's first lunar trip in over 50 years, following previous delays due to fuel leaks. NASA has a six-day launch window starting April 1, with risks acknowledged by officials. New administrator Jared Isaacman has proposed changes to accelerate the Artemis program, including an extra practice flight and shifting lunar landing timelines. An audit highlighted the need for a clear rescue strategy for lunar crews, especially given the challenges of landing near the Moon's south pole.
