KENNEDY SPACE CENTER, FLA. - Inside the mobile service tower on Launch Pad 17-B on Cape Canaveral Air Force Station, workers help guide the Boeing Delta II second stage for the STEREO launch onto the first stage for mating. STEREO stands for Solar Terrestrial Relations Observatory and comprises two spacecraft. The STEREO mission is the first to take measurements of the sun and solar wind in 3-dimension. This new view will improve our understanding of space weather and its impact on the Earth. STEREO is expected to lift off in August 2006. Photo credit: NASA/George Shelton
