[extropy-chat] Soyuz Hubble Repair Mission

[Mike Lorrey]

My recommendation is instead is for the USAF to orbit the Orbital
Transfer Vehicle they developed several years ago at Phillips Lab and
never launched, hook that up to Hubble, and use it to move Hubble to
the ISS for servicing. It could then be used to put Hubble into a much
higher orbit as well and enable it to return to ISS in the future for
servicing, refuelling, etc.

The Phillips OTV uses passive solar thermal power to run a plasma
engine.
