It ’s spring on Mars and the cryptical polygons are in efflorescence , a new image from the orbiting High Resolution Imaging Experiment ( HIRISE ) photographic camera shows .
Recorded on March 30 , 2022 , the prototype reveals a patchwork of white zig - zig crack across the Martian dirt at high parallel , with occasional sprays of grim and blueish mist fan out between them . The zig - zags and colorful spray are touch feature article of Martian outpouring , when hide reservoir of subterraneous ice rear up against the wry Martian surface , researchers at the University of Arizona — which manages the HIRISE mission — write in astatementon Monday ( June 20 ) .
Polygons crack across the Martian surface as hidden ice expands and contracts with the seasons.
" Both water and dry ice have a major role in grave Mars ' surface at high latitudes , " the researchers wrote . " water supply ice frozen in the soil part the ground into polygon . "
The edges of these polygon become cracked and fray in spring as aerofoil trash transforms from a satisfying into a gas — a process known as sublimation . When this shift come about , vent-hole of juiceless ice spraying out of the Martian aerofoil , leaving dark , fan - shaped deposits of particles spread across the ground , the researchers said . Where grim particles sink back into the dry ice on the aerofoil , bright mark ( run across as whitish - blue streaks in the image above ) tarnish the ground .
A individual Methedrine release can open and tightlipped multiple times , spraying speck in different directions across the Martian aerofoil depending on the farting . That ’s why some area show several unlike light and sorry stripe jutting out of a undivided volcano . Both the fans and polygons can stick around for many years , slowly warping the Martian landscape painting as internal-combustion engine expands and contract seasonally .

The HIRISE camera rides aboardNASA ’s Mars Reconnaissance Orbiter , which began its mission in 2006 . Soaring between about 155 and 196 air mile ( 250 to 216 kilometers ) over the planet , the orbiter has captured a treasure trove of bizarre and amusing images over the preceding few decades . For example , in 2018 , the satellite glimpsed a organization of rock music and volcanic crater that loo identical to thebug - eyed Muppet Beaker , meep - meeping near the Martian south pole .
Perhaps even more impressive are the orbiter’simages of Valles Marineris , the largest canon in oursolar system(and therefore the largest known canon in the universe ) . traverse nearly 10 time as longsighted asEarth ’s Grand Canyon and three times thick , the canyon remain a mystery of Martian geology ; scientists are n’t really trusted how it formed . If any Muppets were involved , they ’re keep the true statement to themselves .
