More than a dozen photographers line up to photograph the Genesis-Delta launch vehicle after rollback of the Mobile Service Tower (right) on Launch Complex 17-A, Cape Canaveral Air Force Station. The Genesis launch is scheduled for Aug. 1, 2001, from CCAFS.; however, a gray overcast sky forecasts a questionable launch effort due to weather conditions. Genesis will be on a robotic NASA space mission to collect just 10 to 20 micrograms -- or the weight of a few grains of salt -- of solar wind, invisible charged particles that flow outward from the Sun -- and return them to Earth. This treasured smidgen of the Sun will be preserved in a special laboratory for study by scientists over the next century in search of answers to fundamental questions about the exact composition of our star and the birth of our solar system
