Fourth time is a charm for SpaceX as they finally launch six Orbcomm OG2 satellites to orbit. This morning’s launch which was delayed slightly to resolve a ground system issue lifted off at 11:15 am EDT when the nine Merlin 1D engine’s on the first stage roared to life. Ten minutes later the second stage completed it’s planned burn leaving the craft in it’s intended orbit.
SpaceX webcast the launch up to the point where the second stage finished firing, separation of the satellites will occur later once the spacecraft reaches the desired drop off locations.
Update 12:04 pm EDT – Marc Eisenberg CEO of Orbcomm tweeted that all six satellites were successfully deployed.
Update 1:27 pm EDT – Elon Musk tweeted updates on re-entry of first stage
The planned launch of six commercial communications satellites for Orbcomm has been delayed. The planned static fire test on Thursday was called off after SpaceX ran into technical trouble during the countdown. The static fire test was rescheduled for Friday but was stopped while the rocket was being fueled. SpaceX announced that the OG2 satellites and rocket was in a safe condition and would be rolled back to the integration facility.
At present a new launch date/time is not available.
