Oh, hi! Project creator here.

I am very happy that you folks are showing interest but I am also terrified because this thing is definitely not ready for primetime, yet. The discerning astrodynamicist and/or rustacean will surely find things which are less than optimal or plain wrong.

I am also preparing for a trip so I won't be able to monitor this thread closely but I'll try to answer question wherever I can.

Can I build a solar system simulator with this? Looking for calculating the absolute positions of planets and moons with the sun at 0,0,0 given a datetime. Kepler calculations for planets, moons etc would be fine, as long as I can insert arbitrary objects and calculate their trajectory using gravity. Can this project do that?

Hey, this is really impressive stuff, talk about a dream job! Two quick questions if you find the time+interest:

1. What does "safe" imply? Type safety, maybe? Or just a general synonym for "few bugs/well tested"?

2. What kind of industry is this primarily envisioned for use in...? I have experience in the satellite industry (GRE and TT&C) but I was surprised to not see the usual buzzwords on this page, namely "TLEs". I get that it clearly does way more than terrestrial orbital work, but AFAIK that's, say, 99.9% of the current space industry.

In other words: is this library for ESA missions??? That would be rad as hell, if so.

also P.S. I love AI art compared to most, but I would def recommend carving out that cool crab and putting on a background of real stars. As you may or not be aware, many scientists have been a tad radicalized about AI, and AI art in particular -- would be a shame if that slowed adoption of a cool project!
