Hey, im very new to kerbal and have made a satilite and got it into orbit, the problem is i cant start a maneuver because my radioactive engine wont work even with fuel or power. it works in earth but not strong enough to lift itself so its only use is space. All appropriate answers are greatly appreciated. And could someone tell me how to add my file on here so people can see what the problem is if needed. :P here is a screenshot through Gyazo https://gyazo.com/58cf80a2b1bafab174f68586ae021b80 https://gyazo.com/8fa7c6e87c9da8ce07a6730c1cd6f170 https://gyazo.com/1e35aa6076f20607f974b011a97f4105
