SES 9 @ 108.2°E Satellite Launched successfully !!
Upgraded Falcon 9 successfully lifts SES-9 in first Mission to GTO, 1st Stage Landing fails

A SpaceX Falcon 9 rocket took to the skies on Friday, lifting off from Florida’s Space Coast to boost the SES-9 commercial communications satellite to Geostationary Transfer Orbit. Coming after multiple delays, this flight to a high-energy Supersynchronous Transfer Orbit with a heavy payload demanded the entire performance of the Full Thrust version of the Falcon 9 in a flight with very tight fuel margins. The Falcon 9 carrying the 5,300-Kilogram satellite leapt off its launch pad at Cape Canaveral Air Force Station at 23:35 UTC, thundering into the twilight sky with a thrust of nearly 700 metric-ton-force and guzzling down 2,500 Kilograms of supercold propellants every second. The first stage fired for just over two and a half minutes before handing over to the MVac engine of the second stage that completed two burns – first placing the stack into a Low Earth Parking Orbit followed by a second burn that was programmed to use up the entire propellant reserve of the second stage to boost the satellite into as high an orbit as possible. SES-9 was sent on its way 32 minutes after liftoff into its target orbit. After sending the second stage on its way, the Falcon 9 booster went through the motions to fly itself to the Autonomous Spaceport Drone Ship, stationed 660 Kilometers from the SLC-40 launch pad. Sending a satellite to a high-energy trajectory created a particularly extreme re-entry environment for the first stage since not enough propellant was left to slow the stage down, let alone flying it back to the Space Coast. The booster was successful in surviving the re-entry and maneuvered to the Drone Ship, firing its engines for its landing burn, but appeared to come in off-center before video from the drone ship was lost. SpaceX CEO Elon Musk confirmed that the first stage made a hard landing on the Drone Ship in another close call of achieving SpaceX’s first landing at sea. For SES-9, Friday’s liftoff came after a very long road to the launch pad, slowed down by last June’s Falcon 9 launch failure, leading to a half-year stand down at SpaceX. Initially, SES-9 was first on the SpaceX manifest, set to ride the return to flight mission coinciding with the debut of the Falcon 9 Full Thrust variant, however, plans were changed and Orbcomm became first on the firing line to allow for an opportunity of an in-space re-start test of the modified MVac second stage engine before relying on a clean re-ignition to deliver a satellite to orbit. SES initially aimed for launch in the fourth quarter of 2015 and the company’s 2016 revenue forecast included substantial revenue generated from the commercial operation of SES-9. Some pressure was added when the launch of Falcon 9 slipped from a January target into February with additional days of delay from last into this week when Falcon 9 encountered launch scrubs due to trouble with the intricacies of its sub-cooled Liquid Oxygen propellant. This week, the vehicle was kept on the ground by strong upper level winds over Cape Canaveral, also threatening Friday’s launch opportunity. In order to keep the original in-service schedule for the satellite, SpaceX accommodated a request by SES to change the mission profile in order to boost the satellite closer to its operational orbit. The SES-9 satellite hosts an all Ku-Band payload comprised of 57 high-power transponders, equivalent to 81 standard 36MHz transponders. Reaching Geostationary Orbit, the satellite will be located at 108.2°E to deliver a variety of services to up to 23 million households in the Asia-Pacific Region, serving rapidly expanding TV markets and delivering data, video and mobile communications services. SES-9 also provides mobile communications services with seamless coverage across frequented aeronautical and maritime traffic routes across the Indian Ocean. http://spaceflight101.com/ses-9-launch-success/ |
