This is a much better version, so I'm deleting the old smudgy looking one.

The Time History of Events and Macroscale Interactions during Substorms (THEMIS) mission was a constellation of five NASA satellites (THEMIS A through THEMIS E) that studied energy releases from Earth's magnetosphere, magnetic phenomena that intensify auroras.
The THEMIS satellites were launched February 17, 2007 from Cape Canaveral Air Force Station Space Launch Complex 17 aboard a Delta II rocket. Each satellite carries identical instrumentation, including a fluxgate magnetometer (FGM), an electrostatic analyzer (ESA), a solid state telescope (SST), a search-coil magnetometer (SCM) and an electric field instrument (EFI).

The five THEMIS satellites are still up there, and still working.
