A mysterious Chinese government satellite, believed to be a military-operated early warning station, successfully launched into orbit Feb. 4 on top of a Long March 3B rocket.

SpaceX scrubbed a Falcon 9 launch attempt Thursday to evaluate a “slightly high” pressure reading in the rocket’s upper stage liquid oxygen tank, and officials have rescheduled the company’s final mission of the year for Saturday morning.
