At Astrotech Space Operations in Titusville, Fla., one of the probes of the THEMIS spacecraft is revealed after the crate and cover were removed. THEMIS, which stands for Time History of Events and Macroscale Interactions during Substorms, comprises five identical probes that will study the dynamic and colorful eruptions of auroras. THEMIS is scheduled to launch Feb. 15 from Cape Canaveral Air Force Station. Photo credit: NASA/George Shelton
