It was conceived before me; it was kicking around the halls of Stanford back when I went to school there; and it will be launched on a Delta II from Vandenburg AFB - the kind of mission I worked on in my youth. Enough about me, though. It hopes to answer the question, does space twist as well as bend? Or to put in scientific terms, does the earth drag space time with it as it spins -- what's known as frame dragging, and a still unproven prediction of General Relativity.
