Artemis II Moon Mission Simulator in the Browser
I built a browser-based simulator of NASA's Artemis II mission — the first crewed lunar flight since Apollo 17. You fly the actual mission profile: launch to parking orbit, raise to High Earth Orbit, fire Trans-Lunar Injection when the Moon is in position, swing behind the Moon, and return to Earth. The physics uses RK4 integration with real Earth and Moon gravity. Have fun experimenting with what happens if you don't time it right!
Artemis II Moon Mission Simulator in the Browser launched on April 5, 2026 with 5 votes, #1,846 of 21,248 launches that month and more than 75% of that year's launches.
What it does
Plan an SLS-inspired ascent, time a translunar injection burn, and try to earn a safe free-return around the Moon.

Rocket Launch and Orbit SimulatorJan 2026 · donutthejedi.com · ▲166I (17y/o) have been developing a rocket launch simulation that allows the user to explore what it's like launching a rocket from earth and putting it into orbit. This idea originally started as an educational simulation but as i've gone more down the rabbit hole the more i've wanted to make it realistic. The problem is that I've never had a formal orbital mechanics class or anything like that so I don't know what I'm missing, what I currently have implemented is: Variable gravity Variable Atmospheric drag (US Standard Atmosphere 1976) Multi-stage rockets Closed-loop guidance /…

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.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
