The China National Space Administration (CNSA) has released new data from its Tianwen 1 rover and Zhurong rover, state media network CGTN reported.
Launched on July 23, 2020. Tianwen 1 and Zhurong, along with the lander, reached Martian orbit on February 10, 2021; the orbiter works for almost 800 days. The rover and lander reached the surface Mars three months later, on May 14, the rover had so far traveled 6,302 feet (1,921 meters).
now This is reported by CGTN that CNSA announced that the orbiter and rover sent back 1,480 gigabytes of raw data – some of which supports the hypothesis that an ancient ocean once existed on Utopia Planitia, the vast Martian plain that Jurong is exploring.
Scientists analyzing the data discovered the existence of hydrated minerals in “duricrust”, a hard mineral layer on the soil that usually forms due to the evaporation of groundwater. Scientists say the find proves there has been “significant liquid water activity” in the region over the past billion years. They also determined “that Martian soil has high bearing strength and low friction parameters,” indicating erosion by wind, water, or both.
The hypothesis that there was once a liquid water ocean on Mars is not new – recent climate simulations also pointed to the existence of such an ocean. And, in fact, scientists even discovered a massive an underground ice deposit under the Utopia plateau years before Zhurong’s arrival.
Both Tianwen 1 and Zhurong will continue to explore Mars for evidence related to water, but the two robots will also carry out other investigations. CNSA said its scientists are studying “the relationship between the density of rocks on the surface of Mars and the degree of surface erosion, the distribution of ions and neutral particles in the space environment near Mars, and the gravitational field of Mars.” to CGTN.
