Watch the Falcon Heavy fire up its engines

A wide-angle view of the Space X Falcon 9 rocket test firing at Kennedy Space Center’s launch pad 39A during final preparations for it scheduled blastoff with the EchoStar 23 communications satellite.

SpaceX teams at Cape Canaveral raised a Falcon 9 rocket vertical at the Complex 40 launch pad and performed a static fire test Friday. The Falcon 9 will be used to launch a commercial geostationary communications satellite no earlier than Monday at 7:10 p.m. EST (0010 GMT Tuesday).

Built for hauling rockets aloft to launch satellites, the world’s biggest airplane landed Saturday after a widely-anticipated test flight over California’s Mojave Desert, six months after the death of billionaire benefactor Paul Allen clouded the future of the project.
