NASA spots dramatic 'field of ice blocks' collapsing on Mars If a slope falls apart on Mars and no one is around to hear it, does it make a sound? Probably. NASA's Mars Reconnaissance Orbiter spacecraft captured before-and-after images showing part of Mars' north polar cap collapsing. |

The MRO HiRise camera team at the University of Arizona put together a
GIF showing the radical change in the landscape. "This animation shows
where a section of the slope at right has collapsed since three
Mars-years ago and deposited a field of ice blocks," wrote planetary
geologist Alfred McEwen for a HiRise image release on Friday. A Mars-year lasts for 687 Earth days. MRO snapped the second image, the one showing the ice-block remodel, on Dec. 25, 2019. |

The orbiter's longevity and high-resolution camera have made it one of
science's most valuable eyewitnesses to changes on Mars.

The HiRise team has caught Mars in the act of redecorating before. A
dramatic image from 2019 showed a cloud of dust from an avalanche. These
natural processes are something Mars and Earth have in common. Gravity
and the changing of the seasons can leave an impressive mark.
