NASA is making major changes to its Artemis Moon program. On Friday, Administrator Jared Isaacman announced the space agency would carry out an additional flight in 2027 to test commercial lunar landers from SpaceX and/or Blue Origin. The new mission will take the place of Artemis 3, which previously would have seen NASA attempt to land on the Moon for the first time since 1972. The flight will also see the agency test a new spacesuit made by Axiom Space.
