At Astrotech Space Operations in Titusville, Fla., workers help guide the upper portion of the transportation canister onto the lower portion. The canister encases the STEREO spacecraft for its move to Launch Pad 17-B at Cape Canaveral Air Force Station. 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 Aug. 31. Photo credit: NASA/Kim Shiflett
