Kerbal Space Program was once afflicted by a bug the fans dubbed the "Deep Space Kraken", whereby if you travelled far enough from the origin of the game's coordinate system, floating point rounding errors would cause your spacecraft's components to become misaligned and/or clip into each other, resulting in the craft falling apart or exploding for no obvious reason.
The bug was later fixed by defining the active spacecraft itself as the origin of the game's coordinate system. In effect, the spacecraft no longer moves; instead, the spacecraft remains stationary and the entire universe moves around it. Owing to how relativity works, to the player this is indistinguishable from the spacecraft moving about within a fixed coordinate system, and it ensures that the body of the craft and its components will always be modelled with maximal precision.
While elegant, this solution introduced a new problem: it was now possible, by doing certain stupid tricks with relativistic velocities, to introduce floating point rounding errors to everything except the active spacecraft. In extreme cases, this could result in the destruction of the entire observable universe.
Some might call this one of those situations where the solution proves to be worse than the problem. I call it a perfect expression of what Kerbal Space Program is truly about.
My brother plays Kerbal Space Program which means I get constant conversations that are like
And then he'll call me to come look at his rover and be like "yeah the wheels don't work right so this happens" as his vehicle careens into the surface of the planet and is then yeeted out the other side by gravity
I found a tool for KSP that supposedly brute-force iterates through rocket designs in order to find the most optimal one for given launch parameters and delta-v. Let's give it a spin
There are a lot of temporary traffic lights around where I live at the moment, and my new favourite driving game when I'm waiting at one is to read out loud the last 3 letters on the numberplates of the cars coming towards me. (UK numberplate format is AB12 ABC for those across the pond). And as I was doing this I realised that I just sounded like Book Crowley.
after a few hours of coding a many hours of rendering I got something cool in kerbal space program.
ksp has an rpc mod (krpc) which lets you connect to a craft to build your own autopilot and other things. I found a way to give unique id’s to engines, letting me build an array and display images.
First bad apple visualization i’ve made. Suprised I haven’t made one earlier. There’s a good change I make a new one again soon if I can figure out another unique visualizer.
Hey you made that one KSP mod with the egg planet! Also what do you think about Neptune not being aqua blue?
Mesbin in Whirligig World is more of a hamburger bun than an egg--the planet is oblate rather than prolate--it's circular around the entire equator and the pole-to-pole distance is smaller than the equatorial diameter.
anyway
I already knew about Neptune! I guess I knew it wasn't common knowledge exactly but I thought it was well known in the space nerd fandom. Maybe only in the tiny little hyperfocused circles I'm in. The reprocessed images are cool, but I've seen Uranus & Neptune in a 24" telescope and they're exactly the color shown in the new oxford study.
But this is why I already knew:
Hubble Space Telescope has been imaging Uranus & Neptune in visible light for decades and yeah, when processed similarly, they're about the same color. The difference is somewhat exaggerated in the first hubble images, but not in the top row on the second.
Notice that there is a difference, it's just subtle. The primary reason being the white polar cap of Uranus, which is really that pale blue-cyan color. It's a photochemical haze that is produced only on parts of Uranus that are in permanent sunlight--it is destroyed in the night side and the regions of day/night cycle. Under the haze layer it looks almost exactly like Neptune. When Voyager 2 flew by Uranus, the pole pointed at the Sun, so almost the entire sunlit hemisphere of Uranus was in permanent light.
In the second set of images, from Hubble, we see Uranus when it has tilted its pole a little away from the Sun. There's still a polar permanent day, but now there's a larger temperate band with a day/night cycle, and so there's no haze there, only cloud banding and methane absorption. Beneath that haze, Uranus & Neptune would be extremely similar. On the night side of Uranus in the voyager 2 days, had voyager an incredibly bright flashlight, it would likely have seen something more like Neptune on Uranus' back end.
Artistically I still like to exaggerate the color differences between ice giants--real and fictional--so in Whirligig World, Mandrake (a saturn-mass ice giant) is a noticeably darker, richer blue than Rutherford (a super-earth-mass ice giant), despite getting the same instellation from Gememma and Kaywell.
