Moving THEMIS to a spin table for testing at Astrotech

In the Hazardous Processing Facility at Astrotech Space Operations, workers attach an overhead crane to the integrated THEMIS spacecraft. The carrier is being moved to a spin table for spin-balance testing. THEMIS consists of five identical probes, the largest number of scientific satellites ever launched into orbit aboard a single rocket. This unique constellation of satellites will resolve the tantalizing mystery of what causes the spectacular sudden brightening of the aurora borealis and aurora australis - the fiery skies over the Earth's northern and southern polar regions. THEMIS is scheduled to launch Feb. 15 from Cape Canaveral Air Force Station.
