99TheCreator Posted August 22, 2012 Share Posted August 22, 2012 What is the most fuel efficient way to get into an orbit around the sun? When i do it i keep burning straight up and dont stop until im on an escape trajectory. Link to comment Share on other sites More sharing options...
Kosmo-not Posted August 22, 2012 Share Posted August 22, 2012 The most efficient way would be via a slingshot around the Mun. Link to comment Share on other sites More sharing options...
Guest butt head Posted August 22, 2012 Share Posted August 22, 2012 The most efficient way would be via a slingshot around the Mun.and minmus but thats a hard shot its better to go for the mun if you can only hit 1 Link to comment Share on other sites More sharing options...
ggPeti Posted August 22, 2012 Share Posted August 22, 2012 The most efficient way is to never lift off. You're already orbiting the Sun Link to comment Share on other sites More sharing options...

DonLorenzo Posted August 22, 2012 Share Posted August 22, 2012 Most efficient way to get into a solar orbit (as a free-flying spacecraft..) is to first establish a kerbin orbit so as not to waste fuel due to gravity drag. Also, the lower your altitude when burning for escape, the more efficient it is (an intuitive way to think about it is that the fuel you're burning hasn't been lifted as high, thus having had less previous fuel 'wasted on it'. This adds up when doing long 'straight up' burns).Then from LKO, burn for kerbin escape, if possible incorporating a mun slingshot, however be sure to have the mun slingshot happen AFTER all your fuel is expended. If you burn a little, wait untill you're out at munar orbit, get the slingshot and then complete the burn to escape it might well be less efficient than just burning till escape directly from LKO. Same goes for minmus, but it's going to be a teensy tiny little slingshot which might not be worth the effort. As for getting a specific (higher or lower than kerbins, for instance) sun orbit, do as you normally do and aim pro/retro. Keep in mind that even though you're doing orbital maneuvers you'll be going fast (relative to kerbin), so on the scale of kerbin your kerbol inject trajectory will more resemble a straight line than an ellipse. Keep this in mind when aiming for pro/retro grade.Good luck! Link to comment Share on other sites More sharing options...
