Live coverage: SpaceX launches first upgraded Falcon 9 Block 5 rocket

NASA has selected Maxar Technologies for a $375 million contract to design, build and launch the core element of a mini-space station in orbit around the moon that will double as a deep space research outpost and a staging point for future human expeditions to the lunar surface.

Ground crews took steps this week to prepare for the next Falcon 9 launch, set for no earlier than Jan. 30 with a telecom satellite for SES and the Luxembourg government, as SpaceX officials stressed their rocket was not to blame for the rumored loss of a mysterious U.S. government payload after liftoff Sunday.

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.
