KENNEDY SPACE CENTER, FLA. - The first stage of the Boeing Delta II rocket, slated to launch NASA's Solar Terrestrial Relations Observatory (STEREO), is lifted into a vertical position for installation into the mobile service tower at Pad 17B on Cape Canaveral Air Force Station. Preparations are under way for a liftoff no earlier than July 22. STEREO consists of two spacecraft whose mission is the first to take measurements of the sun and solar wind in 3-D. This new view will improve our understanding of space weather and its impact on the Earth. Photo credit: NASA/Jim Grossmann
