Watch a replay of the Falcon 9 launch with Dragon

Northrop Grumman says it will not continue development of the OmegA rocket after the U.S. Space Force last month picked United Launch Alliance and SpaceX as the military’s two top launch contractors over the next seven years.

Holding up a photo taken by China’s new Mars lander, NASA Administrator Bill Nelson warned Congress Wednesday that his agency faces increasingly stiff competition on the high frontier and that sustained funding for a new moon lander, infrastructure upgrades and other critical programs is vital for America’s space program.

Confronted with pesky problems in the Falcon 9 rocket’s helium pressurization system, SpaceX has shuffled the order of the next two launches, choosing to go ahead with the liftoff of a Dragon supply ship on a cargo delivery flight to the International Space Station around April 10.
