Clearly I watched a different stream, or I live in a world of reason. Unsure which.

That was also early 1970, though. What he is wearing is also something he'd probably be seen just wearing around his house. You aren't better at watching a computer screen because you have nice slacks on instead of blue jeans. I mean, by all means, argue you prefer them dress nice or something...

This is one of the more nickpick-y things I have ever seen. They aren't at a business meeting. Possible customers are gonna be watching if the rocket blows up, not if some guy at a computer has a tie on. Like, "oh did you see those SpaceX slobs? I'd rather spend a whole bunch more and fly with...

Excuse me while I dust off this old O-F account. Oh. My. God.

Wow, that was quite the post. Hopefully I'll have time to play with the maths in practice tomorrow. I'll let you know if I get hung up on anything, but your descriptions made a lot of logical sense, and used some maths I have played with before. Thanks so much!

That was how I was going to end up doing it, if there wasnt a better (or mathier, I guess) way. Actually working this out as the last part in the calculations to do a moon landing thing with a pilot in a different room and mission control in another for KSP. So your help is convenient.

Oh, probably should have mentioned that in the OP. I am doing pen and paper calculations for this. So I am looking for calculations to perform the maneuvers.

I am trying to figure out how to calculate how to return from a moon to the parent planet. How do I know where on the orbit around the moon to burn, and how much delta-v is required?

Only ever seen blue and black. When first exposed to the image I heard it was white and gold before I viewed it, and didn't know anything about the controversy, and I still saw blue and black. It is interesting how our brains account for the low amount of color information in either direction...

So I decided to play around a bit with the vehicle I had around Duna for funsies, and I noticed my burntimes were still way off for even small orbit changes, which wasn't ever a problem. It so happens I started to mistake my fuel mass as my vehicle mass right as I started tackling the hyperbola...

Okay, so it was indeed my misunderstanding of what the equations calculate. Those two velocities would be the correct ones then. (same goes for dgatsoulis' work) The burn time is 100 seconds for 846 m/s. In practice it takes 147s to circularize. 76s calculated for capture, 114s actual. (31% and...

So I am having some difficulty calculating this. Not sure where I am going wrong. Probably misunderstanding one of the variables. my orbit stats and such: planets gravitational parameter: 301.36321 km^3/s^2 planet radius = 320 km (The planet is Duna from KSP, so that is where those values come...

Awesome, thanks a bunch! I'm surprised I didn't find either of those links while doing my own research. Look like an awesome resource.

So I am trying to find out how to calculate the delta-v required to get into an orbit with a desired periapsis around a planet when coming from a hyperbolic orbit, and my googlin' has failed me thusfar. Does anyone know how to do that?

Someone texted me this happened and I totally didn't believe it initially. Very unfortunate.
