I'm planning a mission to Moho, with this ship >[http://imgur.com/NOOhvvF] The problem lies in the fact that the TWR is so low that it has a 27 minute burn. When I split the node, I end up just burning straight into the atmosphere of Kerbin. Is there some way to perform this burn, or should I modify the ship to have a higher TWR?
