Mars is a major planet divided in two . The southerly cerebral hemisphere is made of highlands , mark with many large crater , vent , and canyons . The northerly hemisphere is instead marked by smooth lowlands . The Red Planet had a sozzled past and it is think to have had an ocean covering the northern cerebral hemisphere . unexampled data from the Chinese roverZhurongagrees .
Evidence collected both in space and on the ground let on more evidence of sway and terrain that were probably altered by weewee . The squad can not be certain yet whether it was a maritime environment , flowing urine , or ice that alter these Rock , but urine was take . Zhurong had already find evidence of some weird water - based shenanigans when it discovered peculiarburied polygonal social structure .
Zhurong landed on Utopia Planitia on May 14 , 2021 and worked on the surface of Mars for just short of a yr . It became inactive due to a sirocco and the Martian wintertime , with China announcing its demise almost a year afterit stop working .
Utopia Planitia was deliberate , for a time , the possible nearshore zone of the sea , and this is their reasoning . The workplace suggest that the landing place country of Zhurong can be divided in two . One part has weewee - related features that are not dependant on the amount of piss that is present ; this is to the south .
To the north , there is an area that also has water - have-to doe with features , but from orbit it seem like those features call for a larger presence of water to have form . In the scenario researchers envisioned , a large ocean was present around 3.65 to 3.68 billion years ago . It in all likelihood had a frozen surface . Over the following 230 million yr the ocean retreated , until it melt totally .
Zhurong landed in the southerly part of the nearshore , the one without the abundant amount of piddle . It confirmed the front of mineral that were indeed created in water or methamphetamine hydrochloride interactions , but it could n’t for sure say that those stone were falsify by an ocean or by another water event take on place eons ago .
Across the Red Planet , rovers and orbiter have found a wealthiness of evidence ofrivers , lake , and even of thispossible northerly sea . These mission are building a lucid picture of what Mars had been like but there are still lose piece of the puzzle . Mars might have been hot and crocked orcold and wet , or both for a prison term .
A delegacy further northward from the Zhurong landing place internet site might find more incontrovertible grounds that there was an sea on Mars , and what that sea might have been like .
The study is publish in the journalScientific Reports .
