What it does
SpaceTrekk is a scientifically accurate, real-time 3D solar system simulator. It uses NASA JPL data, Keplerian mechanics, and Newton–Raphson solvers to render elliptical planetary orbits with sub-kilometer precision. Explore all 8 planets, dwarf planets, major moons, constellations, and spacecraft in an interactive WebGL environment. Travel through time from 1900–2100 to visualize past, present, and future celestial motion
Explore all 8 planets, dwarf planets & real NASA spacecraft in stunning 3D. Live orbital mechanics, Voyager tracker, James Webb — free in your browser.
SpaceTrekk is an interactive 3D solar system simulator that requires JavaScript and WebGL 2.0 to run. Please enable JavaScript in your browser settings, then refresh this page. Supported browsers: Chrome 90+, Firefox 88+, Safari 14+, Edgefrom spacetrekk.com

Atlas of Space2025 · atlasof.space · ▲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…

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…

Beautiful 3D ISS tracker with live video and near-realtime clouds2024 · iss.matteason.co.uk · ▲139This 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…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
