On February 17th, a Delta II rocket made an mind-blowing history as it lifted off from Cape Canaveral, Florida, carrying the five satellites of NASA's THEMIS (Time, History of Events and as well as Macro scale Interactions in Sub storms) satellite constellation. It marked in the first time NASA has orbited as many satellites in just one launch. The goal of the THEMIS mission is to find what triggers magnetic sub storms, that could sometimes cause power grids and satellites to fail; it is this occurrence, which makes the colorful Aurora Borealis observed in the night sky.
