About
At Astrotech Space Operations, technicians guide one of the THEMIS probes into position on the probe carrier. When all five probes are in place, the carrier will undergo 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. — NASA KSC · 2002. ABD devlet eseri: kamu mali, ticari islerde de serbestce kullanilabilir.
