  1. The launch of the first Falcon 9 Block 5 booster is scheduled for May 10, 2018 from SpaceX's refurbished Pad 39A at the Kennedy Space Center in Florida.  The window opens at 4:12 pm EDT and closes at 6:22 pm EDT.  The launch will put up the first communication satellite above the nation of Bangladesh in geosynchronous orbit.  SpaceX will place the comsat in a geosync transfer orbit that allows the satallite to raise its own orbit to 22,500 miles in altitude.

  2. When the S1/S2 separation occurs, within a couple of seconds the cold gas (pressurized nitrogen) RCS fires up to rotate the booster ~180°, orienting the engines into the direction of travel for the boostback burn.  On exceptionally clear days you can see the nitrogen plume (it's quite extensive and fleeting as it warms up in the sunlight) from the RCS.  While there could be a nitrogen gas contamination issue because of the proximity of the separated vehicles, I wonder if that is the case because the payload is still in its fairing and environmentally isolated.

    The United Launch Alliance, a 50/50 business relationship by defense contractors Boeing and Lockheed, successfully launched the AFSPC-11 classified communication satellite for the Air Force.  The Atlas 5-551 is the most powerful Atlas variant with a sea level thrust off the pad of 2.4 million pounds.  The Atlas 5-551 vehicle consists of a 5-meter diameter fairing, five AJ-60A solid-fueled boosters and a single engined Centaur upper stage.

    Here's a site with almost every launch, landing, test, clean room views, probes and manned vehicles that was launched or processed through Kennedy Space Center or the Cape Canaveral Air Force Station from 2000 on.
