Workers in the Payload Hazardous Servicing Facility check closely the solar arrays on the Genesis spacecraft. Genesis is designed to collect samples of solar wind particles and return them to Earth so that scientists can study the exact composition of the Sun and probe the solar system’s origin. The white object on the end in front of the arrays is the Sample Return Canister backshell, inside of which are the collector arrays. Genesis is scheduled to be launched on a Delta II Lite launch vehicle from Complex 17-A, Cape Canaveral Air Force Station, July 30, at 12:36 p.m. EDT
