Today I rescued Jeb for Mun (bet that this is a classic!). It's been a while since I kinda crashed against mun but Jeb managed to survive. It was my first time in Mun and I left him stranded for a long time. But I don't forget about him not a single moment. I built an orbital station in mun , prepared a lander, transferred fresh fuel and went to the rescue. I managed to get at 17 km from Jeb's landing. Using his EVA's jetpack he managed to get to 3.2 Km from the rescue ship. He had to save his last 0.40 propergol for reaching the hatch of the lander (some stupid kerbal back in KSC forgot about ladders). We barely managed to land back again in Kerbin doing an extra orbit to aerobrake from 3122 m/s.
Wow. I love this game.
