KENNEDY SPACE CENTER, FL – Amidst the frenzy of ‘Sunshine State’ preparations for Cat 5 monster Hurricane Irma and quite dismal weather favorability odds, the skies surrounding the Florida Space Coast suddenly parted just in the nick of time enabling the Air Force’s secret military X-37B spaceplane to blast off this morning (Sept. 7) on a SpaceX Falcon 9 as the booster nailed another thrilling ground landing back at the Cape.

The SpaceX Falcon 9 roared to life at 10 a.m. EDT (1400 UTC) Thursday morning and soared aloft from seaside Launch Complex 39A on NASA’s Kennedy Space Center into nearly clear blue skies after the classified launch time was kept guarded until just 10 minutes before liftoff.

The Falcon 9 launch was absolutely gorgeous taking place under near perfect weather conditions at launch time and putting on a long sky show as the rocket accelerated to orbit with precious cargo.

After successfully delivering the secret USAF mini-shuttle to orbit, SpaceX engineers completed the 2nd half of the double headed space spectacular when the Falcon 9 first stage booster successfully made a guided soft landing back at Cape Canaveral Air Force Station (CCAFS).

The boosters high speed descent generated multiple shockingly loud sonic booms as the 156-foot-tall first stage approached SpaceX’s dedicated Landing Zone-1 (LZ-1) on CCAFS that reverberated for dozens and dozens of miles across and beyond the Space coast region.

Meanwhile, Hurricane Irma continues barreling towards Florida packing winds of 185 mph as one of the strongest Atlantic storms ever. It is being closely tracked in incredibly high resolution by the new NASA/NOAA GOES-16 (GOES-R) satellite launched late last year on a ULA Atlas V.

The X-37B reusable mini-shuttle is a secretive technology testing spaceplane flying on its fifth mission overall.

The 11,000 pound (4990 kg) state-of -the art reusable OTV space plane is about a quarter the size of a NASA space shuttle. The vehicle measures 29 ft 3 in (8.9 m) in length with a wingspan of 14 ft 11 in (4.5 m).

The X-37B was originally developed by NASA but was transferred to the Defense Advanced Research Projects Agency (DARPA) in 2004.

Since then most but not all of the spaceplane’s goals have been shrouded in secrecy.
