Live coverage: Fresh crew docks at space station

A Russian military spacecraft designed to map variations in Earth’s gravity field, rotation and tectonic movement reached orbit Sunday after a launch aboard a modified Soviet-era missile that spawned an uproar from Canadian environmentalists over where the rocket would drop a potentially toxic booster stage.

The launch of a commercial Bulgarian television broadcast satellite from NASA’s Kennedy Space Center in Florida is set for Monday after SpaceX ran through a mock countdown Thursday and test-fired a previously-flown Falcon 9 rocket’s Merlin main engines.

SpaceX next launch, slated to carry the company’s second set of Starlink broadband satellites into orbit, will be the first to fly with a reused Falcon 9 booster making its fourth flight when it takes off in the coming weeks.
