Both Dynetics and Blue Origin have filled a bid protest with the U.S. Government Accountability Office.

NASA has selected SpaceX’s Starship spaceship to be the first company to put astronauts back on the moon under the Artemis program.

This week, a team led by Blue Origin developing a human lunar lander dropped off its mockup, under development at NASAs Johnson Space Center, giving the astronaut corps a chance train with the mooncraft for the six months or more. The National Team, which includes Blue Origin, Lockheed Martin, Northrop Grumman and Draper, was selected by the U.S. space agency in April to design a human-rated moon lander. SpaceX and Dynetics were also awarded contracts to build human moon landing spacecraft. Blue Origin said in a news release Thursday the National Team delivered an engineering mockup to the Space Vehicle Mockup Facility at Johnson Space Center. All the missions will liftoff from either NASAs Kennedy Space Center or Cape Canaveral Air Force Station.
