I think the average orbital height of the ISS is something like 350KM. The suit won't stay in orbit long without an external boost to overcome atmospheric drag. Maybe we can plot its eventual demise and watch for it burning up in the atmosphere.
I'm glad some think it's cool. I just roll my eyes back and shake my head.
Running only on internal batteries within the spacesuit, SuitSat will have a limited, but interesting lifetime beaming down special messages and an SSTV image as it floats in space. Having no external thrust to adjust its orbit after it is hand-deployed during the EVA, SuitSat will be in a free-floating, but decaying orbit around Earth. It is expected to remain in orbit up to 6 weeks after being deployed.
