Lunar directions · Live
Plan a route anywhere on the Moon.
Terrain-aware directions on foot, by rover, or with VIPER's profile. Distance, travel time, slopes, and sunlight along the way, built on NASA's open terrain data.
Night at Apollo 15 until Nov 17. Leaving at sunrise: 13.5 km by Apollo rover, 2 h 26 min, 32 min in terrain shadow.
Example route

Demo route, terrain mode
Apollo 15 to Mons Hadley Delta
Solid: the terrain route for the Apollo rover. Dashed: the direct line.
- Terrain route, Apollo rover
- 13.5 km

- 12.6 km
| Vehicle | Route | Time, est. | Max slope |
|---|---|---|---|
| Apollo rover | 13.5 km | 2 h 26 min | 20.1° |
| On foot | 14.1 km | 6 h 48 min | 19.1° |
| VIPER | 24.8 km | 2 d 20 h | 11.9° |
It is night at Apollo 15. Sunrise in about 14 days, at 2026-11-17 10:31 UTC. See the horizon from Apollo 15. Leaving at that sunrise by Apollo rover, you would pass into terrain shadow after about 3 min, at 0.4 km, and back into sunlight after about 35 min, at 4.5 km. As of 2026-11-03 10:51 UTC.
Terrain resolution: about 474 m, the LOLA terrain tier around the Apollo landing sites; the model does not include boulders or other surface hazards. How the routing works
Open this route on the map →Horizon view
See the skyline from anywhere on the Moon.
Pick any point and NavLunar traces the terrain in every direction to draw the horizon you would see standing there, with named peaks, how far away they are, and where the Sun sits.
The Sun is below the horizon: 17.1° under it at azimuth 277°. At 2026-11-03 10:51:41 UTC.
Terrain resolution: about 474 m here, about 1.9 km at the farthest samples; no boulders or other surface hazards. How the horizon is computed
Light and time
Move the clock and watch the day and night line cross the Moon. At the poles, see which rims catch sunlight most often and where permanently shadowed regions sit, mapped from published LRO data.
The picture: the south polar region, 360 km across, with the Illumination layer (the share of 2026 each point is lit) and the PSR outlines, as the south pole view draws them. Polar mosaic: NASA Trek, LRO LROC WAC (NASA/GSFC/ASU). Illumination: computed from NASA LRO LOLA terrain by the horizon method of Mazarico et al. (2011). PSR outlines: the LROC PDS release (Brown et al. 2022), permanently shadowed regions of 5 square km and more.

Lunar Grid Reference System
Every place on the Moon,
one address away.
The Lunar Grid Reference System is the official NASA and USGS grid for the Moon: 25 km cells over the whole surface, down to 1 m references. NavLunar draws it on an interactive map and gives every cell, all 9,086 IAU-named features and 57 mission sites a permanent link, with the engine tested against the USGS reference implementation.
