I'm currently doing the contract to rescue a Kerbal from orbit. I have a ship that can get into orbit and I've been able to get it so that the intersects match up, but the speeds of the ship and Kerbal always end up so different that even when I get close enough they just fly by each other and there's no chance for the Kerbal to board. How can I make it so that the speeds are not that different and the Kerbal can enter the empty pod on the ship? I've watched a few videos on how to do this but, they didn't seem to mention this problem.
