After killing off Jeb a few rockets ago he appeared again in my craft designed for a trip around Kerbol and back to Kerbin so I went round the star as intended, got in line with and encountered Kerbin and immediately after entering Kerbin's SOI found myself travelling, at considerable speed, into the path of Mun. This ship was designed to fly back into the SOI, change the path a little in the case of missing, and then parachute safely back where ever it ended up. Instead I decided to attempt a Mun landing with 1 small engine.
That went suprisingly successfully, except that Jebediah was now (and still is) stranded on the Kerbin-facing side of the Mun, so I sent up a 3-crew rescue rocket. That should have been easier but to cut a long story short I failed to get rid of all the horizontal velocity on landing, flipped the craft and it exploded leaving just the crew pod inconveniently stranded over 140km from the Kerbal I intended to rescue. I then looked around hopelessly because no amount of EVA fuel can go that far, and saw a 'thing' on the horizon. Using up all the EVA fuel I had in a disposable Kerbal (I had Bill, Bob and this random guy in the rescue pod) I flew towards this 'thing' and it turned out to be the arch Munolith :D
Mission success :D Disposable kerbal is now a marker point for a hidden structure and I'll humourously murder him later when I get a rocket there. Anyway, he's 22.7km from the rescue craft with 8% fuel left.
