I've got a Kerbal in orbit around Kerbin right now with no fuel or power left. Ran out of fuel during my final retrograde burn after a visit to the Mun. I just finished constructing a unmanned rescue ship that has a "net" built from structural girders and struts (I don't have any docking ports yet in career mode). I plan to send this ship up, sync orbits, then capture the capsule in the net and perform a retrograde burn with the rescue ship.
