In Might 2021, China’s Jurong Mars rover reached Utopia Planesia, a big plateau within the northern hinterland of the planet. Now, preliminary information obtained by the rover reveal that the realm was beforehand topic to intensive wind and probably water environments.
Throughout its first 60 Souls (Mars-Days) mission, Jurong crossed 450.9 meters above the bottom coated with small rocks. On the similar time, the rover is amassing information to be taught extra concerning the planet’s geography and floor ornament, together with acquiring soil and dirt samples and taking photos utilizing a digicam known as NaTeCam.
These primary information had been analyzed by Liang Ding and his colleagues on the Harbin Institute of Expertise in China.
Most of the rocks discovered across the touchdown web site had been carved on one aspect and coated with lengthy grooves, indicating extreme air erosion from the sand. Some rocks have a layered construction, which often arises from interactions with water, the authors mentioned.
“Examples of Jurong’s visits are very brilliant in satellite tv for pc photographs taken from orbit, and the group believes this is because of the truth that the megariples are coated with a wonderful layer of mud,” mentioned Matt Balmey on the Open College within the UK. Didn’t take part within the evaluation. “Which means that these properties are most likely inactive in the meanwhile, as a result of the present removes the sand mud blowing within the air.”
The Rover Martin additionally encountered quite a few megariples on the floor – designed with free precipitation extending as much as a number of meters for air-sculpted options.
Scientists first get a glimpse of the rocks of Utopia Planetia with NASA’s Viking 2 lander in 1976. On the time, they had been broadly interpreted as fragments of basaltic lava, mentioned John Bridges on the College of Leicester within the UK.
“Nonetheless, the touchdown web site rocks right here clearly don’t appear to be the basaltic lava terrain that we affiliate with the crust at Utopia Planetia,” Bridges mentioned. “Jurong represents a way more complicated geographical evolution than was anticipated from Viking 2.”
“From Viking 2, Mars is an instance of a big lump of basalt with some flood paths,” Bridges mentioned. However now the proof from the rover helps a paradigm shift in direction of sedimentary Mars, he mentioned. Soil samples taken on the Jurong web site had been discovered to have an identical composition to these collected by different rovers on Mars.
Total, these early discoveries recommend that the positioning has the potential to offer additional perception into the planet’s floor historical past. Joel Davis on the Pure Historical past Museum in London says, “The actual pleasure is that many scientists imagine that Utopia Planetia as soon as hosted the traditional liquid ocean. “Hopefully, as Jurong continues to discover, we hope it might probably assist reply this query that has plagued scientists for many years.”
