Mission Reports

A threatening layer of clouds stayed away from SpaceX’s launch pad at Vandenberg Air Force Base in California on Tuesday, allowing for clear viewing of a spectacular Falcon 9 launch carrying commercial and scientific satellites into polar orbit.

A SpaceX Falcon 9 rocket powered by a reused first stage climbed into orbit Tuesday from California’s Central Coast, carrying five satellites to upgrade Iridium’s global messaging service and two research craft to study Earth’s water cycle.

A pair of European-built, NASA-backed research satellites set for launch Tuesday from California will extend 15 years of global gravity field measurements collected by the GRACE mission before it ended last year, supplying scientists with data to help track the melting of Earth’s ice sheets and chart the impacts of floods and droughts.

SpaceX’s Falcon 9 rocket rolled out to its launch pad at Vandenberg Air Force Base, California, on Monday, one day before its scheduled liftoff carrying seven satellites into orbit on commercial communications and climate research missions.
