    Is there nothing similar to gradle-wrapper for cmake, where you have a script in the repository that will install the correct version of the binary of the build tool in the project root? That would certainly help avoid hassle like that...

    Is there an analytical solution for time to intercept?

    Oh, I'm very well aware of that. It can however regurgitate well-known solutions to problems in different forms, which served me quite well when I needed newtons method to solve eccentric anomaly in code. The problem is, of course, that if there isn't a well-known solution, it just makes stuff...

    Is there an analytical solution for time to intercept?

    Not entirely cleanly. You can using the eccentric anomaly, and that requires a few iterations, that's true. But they're pretty lightweight.

    Is there an analytical solution for time to intercept?

    Imagine you have two objects. One on a circular orbit, one on an eccentric orbit that intercepts the circular one. The properties of both orbits, the positions, as well as the true anomaly of the intersection point in both orbits are all known. What I need to calculate is if the two objects ever...

    If I got that right, he's saying that starship might be twice as heavy as Musk wants us to believe. That would definitely cut into the payload...

    Trying to name items of an enum used to track actions that were taken in a workflow in the DB. Naming them after the actions performed... not good, because the actions performed at a certain point in the workflow might change in the future. Naming them after the conditions that triggered the...

    I mean, those boxes are very popular to pack up any kind of thing, especially when moving house. Are we sure there's bananas in there?

    Yes, exactly! Knew there had to be a name for it! Thanks! :cheers:

    I'm looking for a word... It's got to do with orbital mechanics, but I can't seem to find the right one, but I'm pretty sure it must exist. Imagine two circular orbits of two satelites around the same central body in the same inclination. They have a frequency between each other that describes...

    Oh, for crying out loud, of course they have a github repo of the thing when you go looking for it! :ROFLMAO: https://github.com/NanowarOfSteel/HelloWorld Complete with chatGPT generated readme! And... a dockerfile? What happened to portability? 😂

    Oh bloody hell, now the madlads did it. They destroyed me. I can barely breathe. Also, can I have an intellij plugin that plays the last 3 seconds whenever I get a nullpointer exception?

    Equations for calculating infalling orbit intercept?

    Thank you very much! I have not implemented the whole DV thing yet, but I've gone through my code with your equations at hand and managed to correct it so I now get valid target intercepts when running it against orekit, so the hard part is done. All in all, the equations I was using were...

    Equations for calculating infalling orbit intercept?

    Not just the the burn, I also need the true anomaly of the spacecraft when it intersects the inner orbit (or the time it needs to get there from apoapsis... one can be used to calculate the other). I need that to calculate the time of the transfer burn so I actually hit the target at the...

    Equations for calculating infalling orbit intercept?

    So, I'm currently devising a very simple trajectory solver for my game. The difficulty is that the game should actually calculate trajectories and maneuvers based on the character's skill, which is a bit more tough than just giving the a player a couple of sliders to fiddle with their DV...
