Martian Map: plan a walk on Mars with real NASA data

Science EVAs

Ready-made Marswalks where NASA's rovers and orbiters have looked closely. Each has a science goal, stations with tasks and kit, and the data layers that matter. Plan this EVA loads one into the planner and checks suits, slopes, sunlight, radiation and space weather.

Your position

No position set. Mars has no GPS — search a place, type coordinates from your lander/rover nav fix, or pick a spot on the map.

Effort per step comes from walking speed, slope, body mass and load (the Pandolf equation), × 0.68 for Mars gravity — the drop measured walking at 0.38 g — and × 1.3 for suit joints. It's then turned into oxygen, CO₂-scrubber, cooling-water and battery use. Work at a stop counts at 250 W (Apollo-like station effort); riding a rover at 150 W. A buddy pair walks home together, so every check uses whichever suit has less of each supply. With a rover, any leg of a route can be driven instead of walked. Sources are in the Science tab.

Landmarks of Mars

Mars' major volcanoes, canyons, craters, basins, polar caps and every landing site. Plan a walk to any of them, see it in 3D, or make a 🖨 3D-printable relief model of it to brief the crew.

Hazards & resources here

Sun, local time and Earth's distance are computed (Mars24 algorithm, JPL orbital elements). The hazard notes come from published mission results — tap a number for its source.

The science behind the numbers

Every figure this app shows comes from a measurement or a published model. Here are the sources, what each one found, and where the app uses it. The small numbers next to a figure link here.

About this project

Built by Rishi (Team Code Huzzlers) for the 2026 NASA Space Apps Challenge, Interplanetary Survival Guide: Martian Map. Source code: GitHub.

AI use: the code was written with help from Claude, an AI coding assistant, working from Rishi's direction; the intro soundtrack is synthesised by that code, and the tour video is a screen recording of this site captioned by AI-assisted scripts. No map, image or number on the site is AI-generated: all of it comes from the NASA, ESA and USGS data and the published studies listed above.
