Original title: Tianwen-1 completed the established scientific exploration mission, and recently released images of Mars

The reporter learned from the National Space Administration that as of today (June 29), both the “Tianwen-1” mission orbiter and the Mars rover have completed the established scientific exploration tasks. The “Tianwen-1” mission orbiter flew normally for 706 days, and acquired medium-resolution image data covering the entire world of Mars. All scientific payloads have achieved global exploration of Mars.

The camera in the center of the orbiter captured the image of Mount Askela, with a diameter of 456km and a height of 18km. The image shows the characteristics of the crater on the top of Mount Askela, and there are multiple crater collapse events.

The “Tianwen-1” probe was successfully launched on July 23, 2020. After 202 days of deep space flight of 475 million kilometers, it rendezvoused with Mars on February 10, 2021, and successfully implemented the capture and braking to enter the orbit around Mars . After three months of detailed inspection of the pre-selected landing area, the “Tianwen-1” probe successfully landed on Mars on May 15. On May 22, the “Zhurong” rover successfully landed on the surface of Mars and began to patrol and explore.

The orbiter’s central camera took images of the Antarctic ice sheet. The image shows the Martian South Pole cap. The study believes that the long-term and permanent polar cap at the Martian poles is mainly composed of dry ice (solid carbon dioxide) and water ice.

On August 15, 2021, the “Zhurong” rover successfully completed the 90 Martian scientific exploration missions, and continued to carry out extended exploration missions. It has traveled 1,921.5 meters on the surface of Mars. 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 camera in the center of the surround takes pictures of the western landforms of the Sailors Grand Canyon. The Sailors Grand Canyon extends over 4000km from east to west, 150-700km wide from north to south, and the deepest can reach 7km.

The orbiter circles Mars 1,344 times, achieving 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 configured by the rover and orbiter have obtained a total of about 1040GB of original scientific data. After receiving and processing on the ground, the standard scientific data products formed are submitted to the team of scientists on a monthly basis for analysis and interpretation. The 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 appropriate time. Scientists from all over the world are welcome to actively apply for research and jointly promote the cause of human exploration of the universe.

The orbiter’s midpoint camera captured images of the Arabian Highlands impact crater, showing the geomorphological features of dozens of impact craters scattered across the region.

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, and shares the orbital data of its Mars orbiter with the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) to carry out collision warning. Cooperation; the “Zhurong” Mars rover and the European Space Agency’s “Mars Express” orbiter carry out data relay communication experiments to realize China-Europe Mars scientific data relay cooperation; Observatory stations in other countries use the “Tianwen-1” orbiter and the “Mars Express” orbiter to jointly carry out occultation observations of the sun and conduct scientific research such as solar wind. These cooperations have achieved good results, enriched human knowledge, and made positive contributions to the construction of a community with a shared future for mankind in the scientific field.

The orbiter’s high-resolution camera captured the image of the edge of the Mond ring crater with a spatial resolution of about 0.5m. The diameter of the ring crater is about 91km. The image shows the geomorphological features of the crater edge of the Mond ring crater. It can be seen that the phenomenon of collapse into the pit is obvious.

“Zhurong” took images of the inspection area. The image was taken before the rover entered the winter dormancy state, showing the local characteristics of a dune landform in the inspection area.
