A SpaceX Falcon 9 rocket lifted off from SLC-4E at California’s Vandenberg Air Force Base at 1:27:34 UTC on December 23, 2017 with the fourth group of ten Iridium-NEXT communications satellites. Using flight-proven first stage B1036, Falcon 9 provided a spectacular sight in the twilight skies over California as it departed to the south with the first stage going through post-separation testing before being expended via ocean impact while the second stage was tasked with a pair of burns to inject the ten satellites into a 625-Kilometer orbit to check off SpaceX’s 18th successful mission in 2017, the fifth with a re-used first stage.
