Curiosity rover team maps route up Mount Sharp
Since landing on the Red Planet in August of 2012, NASA’s Curiosity rover has been collecting data about the geology and chemistry of the Martian surface, finding mineral evidence of past habitable environments on Mars.
Curiosity has been climbing Mount Sharp—a feature that is of interest to the mission’s science team because of its geologically distinct regions—since 2014. Each region represents a different period in the history of the mountain, which rises about 3 miles (5 kilometers) above the floor of Gale Crater.
The rover spent nearly a year exploring Vera Rubin Ridge and is currently in an area called the “clay unit” where it recently started analyzing rock samples.
Among the targets of interest for the science team are the “sulfate-bearing unit,” where sulfate minerals may indicate the area was drying up or becoming more acidic in ancient times; and Gedis Vallis, a feature where a river may have carved a path through the sulfate unit.
