![]() If you're anything like me, you'll want to use it again to take back off. Unless you're using mods, the torrus (i think that's what it's called) or one of the mid-range liquid rockets usually has enough 'umph' to do the job, but the hard part is getting all that equipment into orbit in the first place.Īlso, be sure you have landing gear equipped that extends below the base of your descent engine, so you don't break it off or blow it up on touchdown. The trick is to experiment with different numbers, types and configurations of stages so that you can get a craft into orbit that is powerful enough to do what you need it to. The thing with KSP is that because you build your own space craft, yours will have a different weight and power profile than mine. The engine you have looks like one of the more underpowered ones, that doesn't provide a good thrust/fuel consumption ratio. Ideally, you want about 2 in order to decelerate, land and then take off again and make it back to Kerbin. Okay, from looking at your pictures, I see a couple of problems:ġ. Hope this as least helps you save some fuel getting from a to b. I can write more, but I'm tired and afraid i'm not being very clear. Once you reach pe, fire retrograde only to reduce your velocity and be captured by the target. You want as small a pe as possible, but not one that will have you crashing into the planet.Ħ. #Kerbal space program parachute burns trial#The mechanics for which direction you will need to face in order to adjust your approach are beyond my ability to explain, but a little trial and error (and maybe light reading) will usually suffice. At this point you can fire in any direction, not just pg or rg, and will most likely need to do so to optimize your approach. Since there is no atmosphere on the moons, you can shoot for a much lower pe, somewhere around 20k for mun is good, if I remember correctly. The lack of gravitational resistance is why we wait until the mid-point. Somewhere around the middle of your journey from Kerbin to your target, you will want to do a correction burn to put you on a much closer course. Switch to the map view (m) to make sure your orbit is aligned with your target, and to know when to stop firing.ĥ. This is where it takes experience with your individual craft and your acceleration capabilities to know the most efficient time to fire. (up to 1/4 past the opposite side, depending on the above factors). Depending on the orbital speed of the moon you're shooting for, it's distance from you, and how fast you plan on getting there, you will perform a prograde burn just after passing the opposite side of kerbin. The gimbal in KSP has indicators (green circle for prograde, green circle with an x through it for retrograde)Ĥ. Prograde to speed up/increase altitude of orbit, retrograde to slow down/decrease altitude of orbit. This is because with the exception of changing the inclination of your orbit, burning in any other direction is very inefficient and ineffective. That is to say, you want kerbin to be exactly between you and your target.ģ.NOTE: When doing orbital transfers you always want to burn facing either prograde (the direction your ship is already traveling), or retrograde (the exact opposite direction). After you've established a low, circular (even, as in your apoapsis and periapsis are roughly equal) orbit around Kerbin, wait until your craft is on the opposite side of the planet from the moon you want to get to. ![]() (what follows is a very rough description of a hohmann transfer - you can look it up for more details and a better explanation)Ģ. ![]() The rotation of the planet is the same as earth, and heading east gives you a speed boost that helps get you into orbit by burning less fuel. If you get the timing right, you can have a nice, neat circular low kerbin orbit without having to do any adjustments. ![]() You always want to launch straight upward, until at least around 20k ft, then s-l-o-w-l-y turn through the second half of your launch burn to heading 90 degrees (straight east). I carried over a lot of skills and intuition from "Orbiter" (a painfully realistic space flight sim), and might be able to help you a bit:ġ. ![]()
