    TransX Question about course correction dv after flying by Jupiter

    This question confused me for a long time. I made a journey from Earth to Neptune,using voyager 2 flight plan, departure time is Aug. 20th,1977. After flying by Jupiter ,I found that the mid-course correction dv is at least 60m/s.But when I fly by Uranus,the dv is less than 20m/s,this made...

    I notice that if the the Nonspherical Gravity is set to on,the orbit changes slightly,I had to use a little more fuel to adjust it, so is there any way to predict the orbit in advance so that we can reduce the mid-course correction? I find this in this site...

    Question TransX auto burn

    I have learn TransX for a while.I think TransX is a good tool for space flight.But I have a question:why TransX doesn't have auto burn feature? Sometimes I think auto burn is useful,such as the voyager flight.It can help me reduce trajectory error when I do the eject burn. So I think we can add...
