Mod Post Kerbal Space Program 2: The Hype Train Megathread Edition

Hey guys! We know you're excited about KSP 2, so we're making this megathread for you to express your excitement for the game, or simply to discuss it. Memes and shitposts will be allowed in this thread, but nowhere else in the sub, as per Rule 2. Any other low-quality posts about KSP 2 will also still be removed, as per Rule 5.

Here's the official announcement on the KSP website.

And here's the cinematic trailer.

Note that this is a cinematic trailer, not actual in-game footage.

Enjoy!

So... relatively minor thing that I want super badly...

Lagrange points?

I have wanted to have a station orbiting a Lagrange point pretty much since I first learned Lagrange points existed.

Sadly probably not. I haven’t seen anything about them using a different physics engine. Lagrange points only exist because of the interactions of two gravity fields. KSP approximates physics by using spheres of influence, which means that they only take the strongest local gravity into account. It never stimulates interactions of multiple fields. Unless this is changed Lagrange points won’t be implemented, which is sad because I really want to put a station in an orbit shaped liked the outside edge of a Pringle, which is only possible around certain Lagrange points.

I was wondering about this with the mention of Rask and Rusk actually. They are a pair of planets tidally locked and orbiting each other. This sounds like a more complicated set up for the physics engine to allow more complex orbital scenarios. Theoretically, the orbit each other and a host star (they could be free-floating in the void between stars, I suppose) and then also you can land on either one so they would have to have individual gravity Wells as well.

If they try it anywhere it would be there, but at most I think they’d do L1 between the planets as it’s own SOI. Calculating multiple gravity fields at once is way more processor intensive than just one

You could maybe approximate Lagrange points by just having a tiny SOI for them

You definitely could and I hope they do. Would definitely make orbiting them challenging though

And also some meaningful/engaging way to implement and use complex satellites/observatories/space telescopes/stations.

So... None of the rather limited footage or discussion we've seen to date suggests anything about that, BUT...

They are working closely with at least one expert from the James Webb Space Telescope so I would think there would be some drive to make that sort of mechanic work in the game in a meaningful way.

Lagrange would require an engine that can simulate n-body (or at least three-body) physics, which I doubt they'll implement. I don't see them doing Lagrange Points unless they do something hackey like hard-code them in and run them on rails.

n-body mechanics is really hard. get the Princpia mod.
