NASA's twin STEREO (Solar TErrestrial RElations Observatory) spacecraft, designed and built by APL, arrived by truck at the Astrotech Spacecraft Processing Facility just outside NASA's Kennedy Space Center in Florida. Once unpacked and placed inside a clean room, the observatories will undergo final pre-launch checks. They're scheduled for launch this summer aboard a Delta II rocket from Cape Canaveral Air Force Station's Launch Complex 17-B.
