The European Space Agency's Mars Express orbiter has recently snapped a new series of photos of the planet's surface, revealing scarred terrain stretching for large distances, as well as several impact craters, most likely caused by asteroids that struck the planet in the past.
An area roughly the size of Manhattan was photographed, stretching between the Kasei Valles and Sacra Fossae regions of Mars.
The images were taken with the High Resolution Stereo Camera (HRSC) instrument aboard Mars Express, Space reports.
Kasei Valles is one of the largest outflow channels that have been photographed on Mars thus far.
It spans a distance of about 1,900 miles (3,000 km), connecting the northern Chryse Planitia basin to the southern Echus Chasma.
The new images cover a region on the eastern margin of Kasei, and also include the western margin of the Lunae Planum plateau, and the neighboring Sacra Fossae.
The latter structure is also very large, spanning more than 600 miles (1,000 km).
Planetary scientists believe it may be a fault system that is several hundred meters deep.
To the top of the image, a huge impact crater is clearly visible.
The formation is estimated to be about 22 miles (35 kilometers) in diameter, and shows massive signs of erosion, hinting at the fact that it was formed many years ago.
