Space Exploration Technologies (SpaceX) has successfully completed its first geostationary transfer mission, delivering an SES-8 satellite to its targeted 295 x 80,000 km orbit.  Falcon 9 executed a picture-perfect flight, meeting 100% of mission objectives.

Falcon 9 lifted off from Space Launch Complex 40 (SLC-40) at 5:41 PM Eastern Time on December 3.  Approximately 185 seconds into flight, Falcon 9’s second stage’s single Merlin vacuum engine ignited to begin a five minute, 20 second burn that delivered the SES-8 satellite into its parking orbit. Eighteen minutes after injection into the parking orbit, the second stage engine relit for just over one minute to carry the SES-8 satellite to its final geostationary transfer orbit.  The restart of the Falcon 9 second stage is a requirement for all geostationary transfer missions.

“The successful insertion of the SES-8 satellite confirms the upgraded Falcon 9 launch vehicle delivers to the industry’s highest performance standards,” said Elon Musk, CEO and Chief Designer of SpaceX.   “As always, SpaceX remains committed to delivering the safest, most reliable launch vehicles on the market today.  We appreciate SES’s early confidence in SpaceX and look forward to launching additional SES satellites in the years to come.”

The mission marked SpaceX’s first commercial launch from its central Florida launch pad and the first commercial flight from the Cape Canaveral Air Force Station in over four years.  SpaceX has nearly 50 launches on manifest, of which over 60% are for commercial customers.

This launch also marks the second of three certification flights needed to certify the Falcon 9 to fly missions for the U.S. Air Force under the Evolved Expendable Launch Vehicle (EELV) program. When Falcon 9 is certified, SpaceX will be eligible to compete for all National Security Space missions.
