A browser-based orbital mechanics puzzle game inspired by NASA's Artemis program. Launch a capsule from Earth, slingshot around the Moon using real gravitational physics, and return home safely. Every trajectory is governed by Newton's Law of Universal Gravitation using real Earth and Moon masses and distances.

Built entirely with vanilla HTML, CSS, and JavaScript — no frameworks, no build tools, no server required. Created collaboratively by Tyler Black and Anthropic's Claude as an experiment in human-AI game development. The goal: make orbital mechanics intuitive through play.
