It started as a simple website to show the latest photos from Mars by fetching data from NASA APIs, then progressed into APIs to demonstrate fun space updates (e.g. people in space, space flight table).
It soon evolved into an elementary demonstration of gravity in different celestial bodies (Earth, Moon, Mars, International Space Station for now), which I call 'gravity simulation'. Currently working on more accurate animations to simulate life on different planets. Hope you'll enjoy it!
Tech-stack: React for the web app, the simulator is CSS-only. I used Manim for making explanatory videos.
Disclaimer: just to make it clear, I'm not a physicist or an astronomer, just a space enthusiast. So, I'm sure there might be some inaccuracy in my animations. Would be more than happy if any one of you notice them and let me know.
