I'd be all over it. The Earth that is.
To view our beautiful planet from that perspective is something I've always dreamed of doing.
The closest I've come is the 3-D IMAX movie about the ISS at the Kennedy Space Center and the Mission Space ride at Epcot. Those were pretty good but nowhere close to what I imagine the real experience to be like.
Sure, there's a risk. But sometimes in life you have to take a chance when it comes to doing something truly extraordinary.
