A new NASA GIF of a north-pole crater illustrates some surprising images of Mars, which revealed the Red Planet is quite a dynamic planet.
The Mars Reconnaissance Orbiter tracked the crater which has been through transformation for more than 10 years, with their HiRise (High Resolution Imaging Science Experiment) camera team at the University of Arizona.
“These inter-crater ice deposits shrink and expand or change shape or surface texture from year to year,” said University of Arizona planetary geologist Alfred McEwen, principal investigator for HiRise.
From early 2008, 2010, 2012, 2016, 2018 and up to the end of 2019, NASA’s MRO compiled images that led to the gif, images from over six Mars Years.
The most interesting part to watch is definitely the north pole, from where the HiRise surprised an avalanche in 2019.
