Products that do what Artemis II Moon Mission Simulator in the Browser does
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!

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…

I built this with Claude cause I always wanted to tinker with a simulation economoy and I love space themes. A space-economy sim where nothing is scripted. A few hundred autonomous ships each run their own planner. Some chase the best trade route, take a delivery contract, refuel, retrofit at a shipyard, or dock so the crew can rest before morale tanks. Markets price everything off supply with shortage-urgency multipliers, factions tax and subsidize, populations migrate when they're unhappy, and stations that go broke get abandoned and rot. It started as an Elixir/Phoenix prototype, but…
