long story short, Jeb is stranded between kerbin and Duna orbiting around the sun. I have tried a few attempts to intercept with him for a rescue mission but this has proven difficult since he does not have a gravity well. I am not the best pilot but I was wondering. is it even possible? he has been floating out there for about 2 years now and I imagine he is running out of ways to pass the time.
