I have had the game for a couple of days now. My space program has had much success. I have landed and returned a rocket to the Mun and orbited Minimus. However there are a few Kerbanaughts stranded. There is a command module orbiting Kerbin. There are also a few stuck on the Mun (bad landings - rocket blew up but command survived). There are two rockets orbiting the star. Anyway is it possible without mods to rescue these guys. If so what parts do I need to fit? I only have stock parts with the latest paid version.
