CAPE CANAVERAL, Fla — The Mobile Service Tower (MST) at Cape Canaveral Air Force Station’s Space Launch Complex 37 (SLC-37) was rolled back the length of a football field revealing the United Launch Alliance (ULA) Delta IV Medium rocket within. This impressive display is just one step in preparation for the launch of the rocket’s payload, the Wideband Global Satcom 6 spacecraft. The tower began its journey at 10:27 a.m. EDT. Forty-one minutes later, at 11:08 a.m. EDT, the MST’s movement was complete and the Delta IV Medium launch vehicle was exposed in preparation for this evening’s launch.

“This is my first opportunity to be here to witness a Delta IV launch,” said Jason Meredith with ATK, the company that provides the Gem-60 Solid Rocket Motors that help to boost the rocket to orbit. “This is an exciting event, and I’m extremely happy to be here for the rollback this morning, to witness the launch vehicle being prepared and ready to go. I’m looking forward to launch this evening. This is an amazing part of U.S. history, and we get to be a part of that—just very humbling and amazing.”

Jason Rhian gained Bachelor’s Degrees in journalism and public relations from the University of South Florida and spent countless hours volunteering with NASA and other space groups to gain experience. He has interned with NASA twice. Once at the Kennedy Space Center (KSC) press site in 2007 and with NASA's Exploration Systems Mission Directorate (ESMD) in 2009.

Jason has worked with a number of space-related groups and events - including Google Lunar X-PRIZE team Omega Envoy, the 2009 International Space Development Conference and NASA's KSC press site. Jason has covered over 30 launches. His work has been published in Aviation Week & Space Technology, The Spaceport News and online with,,,, Universe Today and other websites.

Whereas some journalists are comfortable repurposing a press release and using imagery provided to them by the public relations arm of that organization – Jason has made a habit of getting behind the pre-approved announcements to cover the events first hand. He covered President Obama’s remarks live from Kennedy Space Center in April 2010. Jason also flew out to Utah to cover the test fire of Alliant Techsystems second test of the company’s Development Motor-2 (DM-2). More recently, he sat in the backseat of history, flying on NASA’s Shuttle Training Aircraft with STS-135 Commander Chris Ferguson as he trained for the last mission of the space shuttle era during the Terminal Countdown Demonstration Test (TCDT).
