NASA has cleared its Apollo moon rocket for an April launch with four astronauts, marking the first human trip to the moon in over 50 years. The rocket will be returned to the pad at Florida's Kennedy Space Center and could launch as early as April 1. Fuel leaks and other issues with the Space Launch System have prevented the launch. The new Artemis III and subsequent moon landings have been shifted to the new Artemis IV. The Office of Inspector General has warned that NASA needs to develop a rescue plan for its lunar crews.
