China News Agency, Beijing, June 29. The China National Space Administration announced on the 29th that the recent images of Mars taken by the Tianwen-1 probe.
As of June 29, the Tianwen-1 mission orbiter has been flying normally for 706 days, acquiring medium-resolution image data covering the entire world of Mars, and all scientific payloads have achieved global exploration of Mars.
Both the Tianwen-1 mission orbiter and the Mars rover have completed the established scientific exploration missions.
The image of Mount Askra captured by the central camera of the Tianwen-1 probe shows the characteristics of the crater on Mount Askra, and there are multiple crater collapse events; the image of the Antarctic ice sheet shows the polar cap of the South Pole of Mars, and the study believes that Mars The long-term and permanent polar caps of the poles are mainly composed of dry ice (solid carbon dioxide) and water ice; the Arabian Heights crater image shows the geomorphological features of dozens of impact craters distributed in the region.
The Tianwen-1 probe was successfully launched on July 23, 2020, and rendezvoused with Mars on February 10, 2021. It successfully implemented capture braking and entered the orbit around Mars. On May 15 of the same year, the Mars landing was successfully carried out. On May 22, the "Zhurong" rover successfully landed on the surface of Mars and began to patrol and explore.
On August 15, 2021, the "Zhurong" Mars rover successfully completed the 90 Martian scientific exploration missions and continued to implement extended exploration missions.
Affected by the severe winter cold and dusty weather in the landing area, the rover will enter the winter dormancy mode on May 18, 2022 as designed. Around December 2022, the "Zhurong" landing area will enter the early spring season. will resume normal work.
The orbiter circles Mars 1,344 times to achieve global coverage and is currently in normal condition.
In the follow-up, it will continue to carry out global remote sensing detection, and choose an opportunity to carry out expansion technology experiments to carry out preliminary technology verification for related tasks.
After nearly two years of flight and exploration for the Tianwen-1 mission, the 13 scientific payloads deployed by the rover and orbiter have obtained a total of about 1040GB of raw scientific data. After receiving and processing on the ground, the standard scientific data products formed are submitted to the rover on a monthly basis. A team of scientists has conducted analysis and interpretation, and relevant scientific results have been published in well-known academic journals at home and abroad.
These scientific data will be open to scientists around the world at an opportune time.
In the spirit of open and shared cooperation, the National Space Administration actively promotes cooperation with the space agencies and scientific communities of various countries, shares the orbital data of its Mars orbiter with the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA), and conducts collision warning cooperation ; The "Zhurong" Mars rover and the European Space Agency's "Mars Express" orbiter carried out a data relay communication experiment to realize China-Europe Mars scientific data relay cooperation.
At the same time, before and after the Martian solar transit, the National Space Administration and astronomical stations in Russia, Germany, Italy, Australia, South Africa and other countries used the Tianwen-1 orbiter and the "Mars Express" orbiter to jointly carry out occultation observations of the sun. Conduct scientific research such as solar wind.
