Live coverage: SpaceX launches another batch of Starlink satellites

A month after an X-37B mini-space shuttle glided to a landing on Kennedy Space Center’s runway in Florida, the U.S. Air Force announced Tuesday that the spaceplane’s next mission will launch in August aboard a SpaceX Falcon 9 rocket for the first time.

The Falcon 9 first stage booster assigned to launch as soon as March on SpaceX’s first mission with a previously-flown rocket has been test-fired at the company’s development facility in Central Texas.

A European-built satellite with the unusual shape of a house launched into orbit Saturday aboard a SpaceX Falcon 9 rocket from California’s Central Coast, carrying a sophisticated radar altimeter to measure rising sea levels on our home planet.
