Live coverage: China launches three-man crew to Tiangong space station

China added a fourth craft Tuesday to a network of geostationary data relay satellites tasked with keeping mission control in steady contact with Shenzhou crew capsules and a planned space station.

SpaceX and United Launch Alliance have split up to $645 million in new contracts to deploy U.S. Air Force navigation and surveillance satellites into orbit from 2019 through 2021.

The predawn launch from NASA’s Kennedy Space Center of a Falcon Heavy rocket June 25 was the first nighttime liftoff of SpaceX’s heavy-lifter, the most powerful launcher currently operational anywhere in the world. The Falcon Heavy’s two side boosters returned to Cape Canaveral less than nine minutes later.
