“A North Polar Crater”
htmanelski, m o d
This image of a crater near the North pole (84.335° N, 120.393° E) was taken by HiRISE on August 20th, 2008. What you see here is mostly dry ice (solid CO2) which accumulates at the poles seasonally. This was taken in northern summer, when the seasonal CO2 ice cap is thinning, revealing beautiful red material on this small crater’s slopes.
The width of this image is about 1 km.
