Clearing a path to space
KENNEDY SPACE CENTER, Fla. -- An HH-60G Pave Hawk helicopter patrols the sky over NASA's Kennedy Space Center in preparation for launch of Space Shuttle Discover March 15. At exactly 7:43 p.m., the shuttle's massive engines erupted in a tower of flame, sending the shuttle on its way to the International Space Station, where it will deliver a final pair of power-generating, solar-array wings and a truss segment. The 920th Rescue Wing provides first-response emergency medical and search-and-rescue support for every NASA shuttle and rocket launch. (Courtesy photo NASA/Jeff Wolfe)
