Live coverage: PSLV successfully launches from India

Gearing up for the third Falcon 9 launch in less than two-and-a-half weeks, SpaceX fired up a rocket booster at Cape Canaveral on Thursday ahead of an early morning launch Tuesday with an Indonesian communications satellite.

SpaceX’s next launch with a European-built communications satellite has been delayed to no earlier than March 28 to study a problem with a helium pressurization system on the Falcon 9 rocket, officials said Tuesday.

SpaceX’s fired the engines of its Falcon Heavy rocket at launch pad 39A at 12:30 p.m. EST (1730 GMT) on Wednesday. The crucial pre-launch engine test has been repeatedly delayed since the rocket returned to the launch pad earlier this month.
