Live coverage: Ariane 5 soars into space from Kourou

SpaceX has delayed the launch of the SES 12 communications satellite until shortly after midnight Friday at Cape Canaveral, allowing teams additional time to complete pre-launch vehicle checks and wait for improved weather conditions. The launch, which was previously set for Thursday, is expected around 12:29 a.m. EDT (0429 GMT) Friday.

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.

The third spacecraft to join India’s growing regional navigation system blasted off and flew into orbit aboard a Polar Satellite Launch Vehicle.
