Curiosity’s View Into Marias Pass
The image above shows Curiosity’s view southwest into “Marias Pass,” a low valley in Gale Crater where the rover was on May 22, 2015 – mission Sol 992. At the left (east) edge is the western slope of a rise called Akipuni Mountain, and Mount Shields rises off to the right (west).

The site is a bit of a backtrack from its previous location at Logan Pass, since the rover has been experiencing some slipping on the loose surface material in the area.
“Mars can be very deceptive,” said Chris Roumeliotis, Curiosity’s lead rover driver at NASA’s Jet Propulsion Laboratory, Pasadena, California. “We knew that polygonal sand ripples have caused Curiosity a lot of drive slip in the past, but there appeared to be terrain with rockier, more consolidated characteristics directly adjacent to these ripples. So we drove around the sand ripples onto what we expected to be firmer terrain that would give Curiosity better traction. Unfortunately, this terrain turned out to be unconsolidated material too, which definitely surprised us and Curiosity.”
