Claude codes turn-by-turn directions for the Moon

Claude built a working navigation app for the Moon from scratch. It plans drives over real NASA terrain, steering around craters too steep to enter, cutting across ones shallow enough to drive, and explaining every turn, all on a hand-built 3D globe in the browser with no libraries.

Every number on screen comes from public, freely available data:
- Terrain and crater depths: NASA's LOLA laser altimeter aboard the Lunar Reconnaissance Orbiter (NASA PDS)
- Imagery: the LROC camera's global mosaic, via NASA's Scientific Visualization Studio (NASA/GSFC/Arizona State University)
- Place names: the Gazetteer of Planetary Nomenclature (IAU/USGS)
- Landing sites: published NASA mission coordinates

All US-government public domain. Thanks to the LRO, LOLA, and LROC teams and the USGS Astrogeology Science Center for making this data open to everyone.
