The U.S. Space Force announced Tuesday that it awarded $384 million in contracts to United Launch Alliance and SpaceX, giving each company two missions to launch military satellites in 2023.

Nine Merlin main engines on a SpaceX Falcon 9 rocket ignited at 12 p.m. EDT (1600 GMT) Friday, April 17, during a hold-down test-firing on launch pad 39A at NASA’s Kennedy Space Center in Florida.

Debris from SpaceX’s Falcon 9 rocket booster returned to shore in Southern California late Monday after it tipped over on touchdown on a landing platform in the Pacific Ocean following liftoff with a ocean study satellite.
