The NASA-funded Subsurface Water Ice Mapping (SWIM) project released its fourth and most recent map of where on Mars.
This map will help mission planners decide where on Mars to actually send the first humans to traverse the planet.
The recently released fourth set of maps is the most detailed and accurate since the project started in 2017.
The new map includes sightings of so-called “polygon terrain.”
There are the seasonal expansion and contraction of subsurface ice causes the ground to form polygonal cracks, indicating more ice hidden beneath the surface.
