Epic Field Recording: NASA SMAP ULA Delta II Rocket Launch by Boyfriend Academy published on 2015-02-28T07:20:40Z At 6:22am in the cold and pitch black morning of January 31, 2015, NASA was set to launch a Delta II rocket carrying the SMAP spacecraft from Vandenberg Air Force Base after a suspenseful 48-hour delay due to inclement weather. A small group of spectators anxiously awaited at the viewing site about 5 miles east of Space Launch Complex 2 (SLC-2). The audio you are hearing is from my field recording at the viewing site.
