Thanks for the short explanation of the manual calculations! If I got more questions, I will look it up:) Such a nice game, you learn so much new while playing it, getting a deeper understanding the more you play. Plus: Nice community, what is going on here? Guess you have to have some passion (and brains) to play this, so manners are more common.

"2.8 tonnes of not- fuel and 2 tonnes of fuel. 4.8/2.8= 1.71 Rwd. That would yield 1,700 m/sec" Is the calculation of dV that simple? If so, I will not rely on MechJeb so much for the future. Thanks for the answers, I will try to get off with the MonoProp left, tho I don't think that will be enough. I will probably try to design a better lander and try to rescue my Kerbonaut! Thanks you very much!

Hello fellow Spacemen, my Kerbonaut finally landed savely on Tylo. Now I hope to get him back home to his family and friends. MechJeb says I have 2970dV left. But I can't get to a 10km orbit where my return ship will pick me up, while the dV-maps claims I just need 2270dV. Am I a bad little spaceguy or has MechJeb made some mistakes? I am afraid it did some wrong calculations and put the dV in the wrong stage. I will add a picuture to make it more clear. Stages viewed by MechJeb (numers as seen in Mechjeb, not the staging sequence at the bottom left side) : 4: Will be left on the ground, just there for the legs (2 of the radial tanks). 3: Two left radial boosters with a little fuel left (612dV), will be dropped soon 2: This is where the most dV should be, but its 0... dV is on the next stage, which is wrong 1. This is where all the dV is located, but this stage already dropped the engine, so no dV at all (only science, command pod, MonoProp and some utility stuff) So is the dV is calculated in stage 1 instead of stage 2, therefore I have less dV left because stage 1 is 3 tons heavier than stage 2? Would be nice if someone could explain me my mistake. Also I would love to know if there is any possibility to save my Kerbonaut:/ Haven't lost one for a long time, except once to the allmighty kraken. Thank you. Edit: Thanks for the answers so far, somehow I failed uploading the picture, here it is now:
