Two space shuttle solid rocket boosters — reusable space hardware that launched on 81 missions — are being gifted to the California Science Center to become part of the museum’s launch pad display of Endeavour.
Passing a major pre-flight milestone ahead of a launch and landing planned early Sunday, a SpaceX Falcon 9 rocket ignited its main engines Wednesday for a hold-down firing at Cape Canaveral.
Watch a view of the Falcon 9 rocket’s liftoff Wednesday from the Kennedy Space Center as seen from the press site around three miles from the launch pad.
