I am reading this article, NASA's WISE Eye on the Universe Begins All-Sky Survey Mission, on NASA's website.
According to this article, NASA's Wide-field Infrared Survey Explorer(WISE) lifted off from Vandenburg Air Force Base on 14 December 2009 at 0909 EST aboard a Delta II rocket.
It is currently in a Polar orbit.
