    Back in time in the SFS Forums

    Well, I decided to have a look at the SFS forums on Wayback machine. Pretty interesting, and I ended up nostalgic for something I never experienced. Anyway, the earliest snapshot was back on May 18th, 2019. Mooncrasher was editing save files and exploring the universe And that abruptly...

    N-body physics

    I was recently researching Principia, and I was wondering how difficult it would be to make a Principia style mod that added N-body physics to SFS. Would the 2D nature of the game impede it? Obviously I would have to somehow gut the current physics engine and make a new one, but is it...

    AEP

    AEP (Advanced Engines Pack) This pack contains some engines well suited for interplanetary and interstellar journeys. All engines are based off of real designs and concepts, so take it up with NASA if they seem OP. All the information about the engines and installation is in the README.md file...

    Rotation

    I've noticed even in a vacuum with torque disabled and no SAS, a spinning object will slow down. Is this unavoidable or a setting? Or is something going on with my specific game?

    Deja vu challenge

    No one seems to do this one... For mine, I ruled out replaceable parachutes instantly (too much work), as well as propulsive landing (needs too much fuel, not enough time for the second stage to get to orbit), and went with airbrakes: Near the top of each stage are grid fin looking solar...

    Orbital mechanics

    Can anyone recommend some orbital mechanics textbooks, preferably not too heavy on the calculus? I hear I may need them for KSP.

    Planet editing

    First: I can't find anything on how to make planet packs in 1.5. Is it the same as 1.4? Second: Are there any other levels of planet editing besides the team totan one? If so, what do they require?

    Buying KSP

    Should I get KSP 1 or 2? KSP 1 is on sale right now, but KSP 2 looks like it adds quite a bit.

    Interstellar custom pack dev. thread

    I'm brand new to modding, but I'm going to make a custom.engines pack with a vast assortment of interplanetary/interstellar engines. I'll be using this thread to post updates and take SOME requests, not all (who knows, though). So far, I have this list of engines: (N2O4's electricity pack will...

    Custom Parts

    I want to make some custom engines that haven't really been explored yet, but I need the tools first. I downloaded unity and made an account, but I can't figure out how to mesh it with the modding toolkit. I am dreadfully new to this (everything) so can anyone help me?

    Any tips for getting into orbit in realistic?

    I recently started playing realistic and wondered if there was anything I should know about getting into orbit (LEO of course)

    CSAT Mission Developments

    Throughout the course of this thread, I will be reporting on the activities of STAR, Space Technologies and Research, as they launch missions to LEO, the Moon, and beyond. I will also be asking for votes on what missions should be kept or thrown away (simulating budget cuts), and mission proposals.

    Loaded the quicksave: Did a not very efficient transfer burn to Venus: I redid the Venus GA to lower my periapsis to almost exactly mercury level, but I forgot to screenshot it, so here's the first Venus encounter: My first mercury encounter/GA: Aaannnd a bunch more: For this one, I...

    Juno: My swingin' on a star submission

    Let's start with my spacecraft and my Europa lander: My spacecraft is similar to my mars mission, but with bigger fuel tanks. I made it as realistic as possible, designed to support 6 astronauts on an 8 year journey. It includes the reentry and LEO Insertion module, at the front, which will slow...
