HIRISE Spots Martian Crater Build up

The northern flatlands of Arabia Terra upon Mars

This image taken by the  Mars Reconnaissance Orbiter   spacecraft’s  HIRISE   instrument on Oct. 23, 2022, of the northern flatlands of Arabia Terra shows craters that contain  curious deposits  with mysterious forms and distribution.

For instance, the particular deposits are located on the southern sides of the craters, although not usually in the north, and are also found only in craters larger than 600 meters within diameter.

Scientists suspect that these functions formed by sublimation of ice-rich material.
