So to return from anywhere, as well as get there, you add all the numbers to get there plus all the numbers again to get back (except the 4500m/s launch from Kerbin) and add an extra 1000m/s for safety. Also adding a 1000m/s like this gives me my margin for error because just going by the numbers on this map I was running out of fuel on the Mun and not able to take off again. But I also assume around 1000m/s is required to get back into a stable orbit around Kerbin that isnt shown on the map (unless you aerobrake in which case returning to Kerbins ground is free). I usually assume the same to take off and orbit is the same required to land - so 640m/s to take off and get back into a stable orbit around the Mun.
#Kerbal space program delta v map how to
Pretty cool map! How do you calculate the d-v required to take off from a planet? I have all these great resources telling me how to get there, but I usually take off by the seat of my pants and hope I have enough to get into orbit.
So all up, if you do it exactly as it says on table (there are other, more efficient ways), you'll need a ship capable of having 8735 m/s Delta V in order to land on Gilly. Another 210 m/s to get into orbit and 35 m/s if you want to land. To get to Gilly, for example, you'll need 4500 m/s to get into orbit, 950 m/s to escape Kerbin's SOI and intercept Kerbol (the Sun), 80 m/s to intercept Eve, (depending how you do the next part) 1310 m/s to orbit Eve and then 1650 m/s to intercept Gilly. From there, you need 860 m/s Delta V to intercept the Mun and you'll need a further 210 m/s Delta V to turn your intercept into an orbit (otherwise you'll just fling off the other side). This 4500 means that you'll need 4500 m/s Delta V (change in velocity) to get into orbit around Kerbin.
If you look at the number in the middle of Kerbin, you'll see that it says 4500.
This map is used to plan your trip to other planets. I'm going to make the assumption you understand Delta V, if not, let us know. Forgive me for sounding like a N00B, but how exactly does one use this map? Thanks in advance.
