SpaceX third try a success
Following two delays because of technical issues during countdown SpaceX successfully launched the SES-8 spacecraft on Tuesday.  This was a critical mission for SpaceX as it was there first to GTO and also the first to require a re-light of the second stage engine to ensure the spacecraft arrived at the proper orbit.

Unlike the previous two attempts the countdown went smoothly and the spacecraft lifted off on time for approximate 9 minute climb to the initial orbit.  Once in orbit the second stage and spacecraft cruised for another 18 minutes before the second stage fired its engine for 71 seconds to place it in the correct position to release the spacecraft into it’s designated orbit.

While the final stages of the flight were not broadcast live Elon Musk sent out several tweets advising of the progress of the mission and confirmation that the spacecraft had been delivered as expected.

Next up SpaceX will be flying another mission from the Cape, this time for Thaicom this was original scheduled to fly at the end of December, however this may change because of the delays in the SES-8 flight.
