Atlas of Spacefree▲770Hello HN! Sharing a recent side project of mine, the Atlas of Space, that I built out to explore the Solar System. As a long-time space nerd, I realized recently that I didn't have a good intuition on the scale, speed, and relative orientation of the celestial bodies around us. So over the break I built out a kind of spatial Wikipedia to click around and learn about planets, moons, asteroids, and other bodies orbiting the Sun. The physics is all simulated in the browser using simple Newtonian mechanics. There's a lot left to do from here, including modeling objects in non-Keplerian orbits…

Hey HN! I made Orbit, an iOS app that allows you to see the satellites, planets, and constellations above you in AR, on a 2D map, and on a 3D globe. The app includes more than 15,000 objects tracked by CelesTrack, together with their pass predictions, descriptions, and detailed orbital data. A searchable catalog of all objects is also available, as well as a built-in chatbot designed to answer any space-related questions you might have. This is my first published iOS app, so any feedback is greatly appreciated! App Store: https://apps.apple.com/app/id6772174570

This is a little hobby project that I hope you enjoy. You can see where the International Space Station is now, with live HD video from NASA, on a realistic 3D globe. The positions of the sun and moon are also accurate, though distances aren't to scale. The clouds are also near-realtime; I span that out into a separate project at https://clouds.matteason.co.uk, where the cloud images I create from EUMETSAT data are freely available. I've got more features almost ready to go, like the ability to turn off all UI, toggleable clouds and turning off the day/night cycle I'd love for…

Made a little Artemis II tracker for anyone else who is unnecessarily invested in this mission: https://artemis-ii-tracker.com/ For those of us who apparently need a dedicated place to monitor this mission instead of behaving like well-adjusted people.

Just for fun and self education, I've built this over a weekend to teach myself why orbits exist, not just show planets going around. Something that was never clearly explain to me in school. It opens with a guided tour that builds the idea up step by step: two bodies and the equal/opposite force, inertia (the Sun is removed and Earth just drifts straight), then "an orbit is falling and continuously missing," cosmic velocities with a little rocket, Voyager 1 & 2's real gravity assists (the clock runs the actual 1977–1989 dates so the planets orbit into their grand-tour alignment and the…
