    Launch Date: June 4, Monday
    Launch Window: 0429-0829 GMT (12:29-4:29 a.m. EDT)
    Launch site: SLC-40, Cape Canaveral Air Force Station, Florida
    Booster Recovery: None expected - 2nd launch of a Block 4
    Booster Type: B1040 - Block 4
    Orbit: GTO 5,300 kg (11,700 lb)

    A SpaceX Falcon 9 rocket will launch the SES 12 communications satellite for SES of Luxembourg. The SES 12 satellite will provide direct-to-home broadcast and other high-throughput communications services in the Middle East and the Asia-Pacific region, including rapidly growing markets such as India and Indonesia. The satellite was built by Airbus Defense and Space. The SES-12 spacecraft has arrived safely at the Cape Canaveral Air Force Station, Florida, on April 12th in preparation for launch. The B1040 booster was originally used to launch the OTV-5 X-37B spaceplane for the Air Force. The booster did a RTLS for that mission.

    This will be a very early launch.

    No recovery? why bother launching if you are not interested in landing?

    Block 4 only gets reused once.

    I am crossing my fingers that a Block 4 gets a third reuse with the In Flight Abort test for Commercial Crew. The TESS booster (B1045) landed on OSCILY in spectacular shape. It's next launch for CRS-15 will also be an easy RTLS recovery with minimal wear and tear as well. So I'm hoping that booster gets a third reuse with the In Flight Abort test.

    The ongoing rumor is that they will reuse the KoreaSat 5A (B1043) booster for the In Flight Abort though.

    Weather for Friday early morning is terrible. Only 40% chance of a launch opportunity. It does improve toward the tail end of the window though.

    First post modified to reflect new launch date of June 4th.

    Heads up to the West Coast people that the launch will happen on Sunday night for you: 9:29 PM.

    I will stay up if there is a landing. But there isn’t one this time.

    Question about the time gap between the end of second stage burn two and when they release the satellite. After the second burn is over, why hold onto the satellite for so long if the second stage is done at that point? Why not release it shortly after the burn is over once everything checks out? If there aren’t any additional burns planned what’s the point of holding onto it for so long after?

    Yay! Went great.
    I love the way the altitude climbs and velocity falls even after SECO2- remarkable to think about that elegant silent HIGH-altitude trajectory....

    Successful launch. Some drama over a lens flare after liftoff. Nothing fell off. Everything else went successful except some mylar shielding came loose on the second stage and flapped around. It didn't prevent the successful deployment of the satellite in the desired position.

    They are waiting for a specific pre-arranged point in space to release. It may take a while to reach that point. Maybe there are some satellite checks that SES needs to do.

    It's a good question and I am just speculating.
