We measured the wind speed, which was two to eight meters per second, something we call a breeze. The maximum speed on record was 10 meters a second, so basically a breeze."

Storyline


China's Tianwen 1 Mars mission has achieved a great deal of engineering and scientific data with its "Zhurong" rover extensively advancing research about the planet for the benefit of future exploration, said a mission leader in Beijing on Tuesday.

Liu Jianjun, chief designer of the Tianwen 1 mission's ground system, said that the 13 scientific devices mounted on Tianwen 1's orbiter and Zhurong rover have generated more than 420 gigabytes of primary data since the mission was launched on July 23, 2020, from the Wenchang Space Launch Center in the southern island province of Hainan.

As of Aug. 15, 2021, Zhurong has worked on the surface of the Red Planet for 90 Martian days, or about 92 days on Earth (a Martian day is approximately 40 minutes longer than a day on Earth).

The solar-powered rover equipped with six scientific instruments has garnered considerable amount of data on the shallow structure of the Martian surface, surface elements, magnetic field environment and meteorological environment.

"For example, our magnetic environment meter mainly measures what the magnetic environment is like on Mars. While the surface composition detector basically measures what elements are in the rocks, soil, and dunes on Mars," said Liu.

According to Liu, the returned data suggest the equipment on Zhurong are functioning well. After processing, the data will be released to the scientific community for further researches.

"Hopefully, by providing these data to our scientists, we can get a deeper understanding of the geology of Mars, and then even see if we can find evidence of the existence of an ancient ocean in the Utopia Planitia, a question that interests many people," said Liu.

The scientist also gave an introduction to Zhurong's findings about the atmospheric pressure and wind velocity on the Red Planet.

"According to our measurement, the Martian atmosphere has a pressure of around 800 pascals. What does 800 pascals suggest? We used to believe that the pressure on Mars was about 1 percent of that on Earth, but our measurement this time says it's 1/120," said Liu.

"Around noon, the temperature was between minus 20 to minus 10 degrees Celsius. Another question people might be interested in is that if there is wind on Mars and how hard it blows. We measured the wind speed, which was two to eight meters per second, something we call a breeze. The maximum speed on record was 10 meters a second, so basically a breeze," said Liu.

The scientist added that Mars, with 687 Earth days in a Martian year, also has four seasons. The current season at the end of spring and the beginning of summer is characterized by relatively moderate temperature and wind speed, which provide a suitable environment for the rover's exploration.
