Possible MSL Landing Site: Survivor No. 6 -- Nili Fossae Trough

Nili Fossae Trough

Nili Fossae Trough is a huge crack in the surface of Mars. The linear trough is about 25 kilometers (16 miles) wide. It formed when a huge meteor slammed into the surface and created the Isidis Basin to the east, one of the four largest impact basins on Mars. The impact caused the Martian surface to deform. The region has one of the largest, most diverse exposures of clay minerals. Clay minerals contain water in their mineral structure and may preserve organic materials. Scientists are excited about studying such deposits to understand past environments that could have supported life. The Mars Science Laboratory rover would land in the center of the trough, amid rocks that splattered outward when the crater formed. Volcanic rocks are also abundant, left behind by cooling lava that filled the trough. Over its mission, the rover would drive westward to a side canyon in the wall of the trough. There, spacecraft have detected a diversity of minerals in the ancient crust.
