Image: Curiosity Rover Surveys Boxwork Region of Mars

Curiosity’s analysis of fractures, nodules, and minerals supports evidence of prolonged groundwater on Mount Sharp, hinting at extended habitable conditions on ancient Mars.

Summary by Phys.org
NASA's Curiosity Mars rover captured this panorama of boxwork formations—the low ridges seen here with hollows in between them—using its Mastcam on Sept. 26, 2025, the 4,671st Martian day (sol) of the mission. These boxwork formations were created billions of years ago when water leaked through rock cracks. Minerals carried into the cracks later hardened; after eons of windblown sand eroding away the softer rock, the hardened ridges were left ex…

NASA reported that Rover Curiosity identified on Mars a system of intersecting mineral ridges that points to groundwater circulation in stages that are later than the scientific community estimates.Structures, known as boxwork, form networks that from space look like cobwebs.They are located on Mount Sharp, a five-kilometre-high mountain that the vehicle has been exploring for years.The finding is relevant because it suggests that the planet's g…
