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
