I have a space station orbiting Kerbin at around1.5 mil kilometers. the station had 5 peoples onboard but one day they all disappeared from the station and just appeared in the space center. is there a way to put them back without docking a new ship to the station? (i tried many times but I'm not able to properly aline with the station, I'm new to the game). Thanks for any help, Karlos.
