MarsGPS

Real directions for getting around on Mars. Pick two points, and MarsGPS finds a route across the actual Martian terrain, the way a map app does on Earth. Every route comes with the data behind it: the terrain, the slopes and grades, the climb and descent, the path around craters and canyons, a side view of the ground in 3D, turn-by-turn steps, and your travel time at the speed of a rover, a crew rover, a bike, or a walk in a suit. Then explore. Every landing site is on the map with its history, the paths the rovers drove, and the photos they took. Open a ground view and look around from the surface where Perseverance, Curiosity, Spirit, Opportunity, Pathfinder, Viking, Phoenix, InSight, and Zhurong stood. It is a way to see the planet that has not really been done before, and it is as easy as a map. It is also engineered to be accurate. Every elevation, grade, and travel time is computed from real mission data, not drawn: NASA's MOLA elevation grid, the Viking and Context Camera imagery, the rovers' own driven paths, and their panoramas. The routes, elevations, and photos ship inside the app, so it works without a connection. The methods and limits are spelled out under About, along with the credits.
