STS-135: The final space shuttle landing

SpaceX’s Falcon Heavy rocket rolled out of its hangar and up the ramp to pad 39A at NASA’s Kennedy Space Center in Florida, then was raised vertical at the seaside launch complex early Monday in preparation for a late-night liftoff with two dozen weather observation and technology demonstration satellites.

Watch as NASA holds a briefing at the Kennedy Space Center on the four agency technology payloads that are part of the STP-2 mission flying into orbit aboard a SpaceX Falcon Heavy rocket.

The mobile platform intended to carry NASA’s Space Launch System will trek to the mega-rocket’s launch pad at the Kennedy Space Center in Florida as soon as Thursday, before heading inside the spaceport’s huge Vehicle Assembly Building for the first time next month.
