STEREO observatories are the focus of attention at a media viewing held at Astrotech Space Operations in Titusville, Fla. The two observatories were mated for launch but will separate into different orbits for their mission.

STEREO stands for Solar TErrestrial RElations Observatory. The STEREO 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.

STEREO is expected to lift off on Aug. 31, from Launch Pad 17-B on Cape Canaveral Air Force Station in Florida.
