Time-lapse video: The Falcon Heavy goes vertical again

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.

This will be the eighth flight of the X-37B and the third time that it will be launched by SpaceX. The Falcon 9 rocket is scheduled to liftoff from Launch Complex 39A at 11:50 p.m. EDT (0350 UTC).

Boeing Co. and SpaceX, selected by NASA last month to carry astronauts to the International Space Station, can resume development of their human-rated spacecraft after officials ordered a work stoppage prompted by a protest by Sierra Nevada Corp., the company left out of the contracts.
