On August 30, when my country’s first Mars exploration mission, "Zhurong", the rover on the surface of Mars for 100 days, the National Space Administration and the People’s Bank of China held China’s first Mars exploration mission in Beijing and successfully issued gold and silver commemorative coins. The ceremony is to commemorate an important step in our successful interstellar exploration journey, leaving China's mark on Mars for the first time, becoming the world's first country to achieve Mars circumnavigation, landing and patrol on a single mission.
The front and back pictures of China's first successful Mars exploration mission gold and silver commemorative coins (from left to right are 150g gold coins, 8g gold coins, and 30g silver coins)
The commemorative coin is the legal tender of the People’s Republic of China and is issued by the People’s Bank of China. There are 3 commemorative coins, including 2 gold coins and 1 silver coin.
The images on the front are the Chinese planetary exploration logo, and the country name and year number "2021" are published, and the patterns on the back are themed on the first Mars exploration mission "Orbit, Landing, and Patrol", and the publication "China's first Mars exploration mission is successful·Tianwenyi Number" and denomination.
The commemorative coin condenses the vast space in a square inch, allowing the spacecraft to rise above the gold and silver coins. It uses a design method that combines realism and freehand brushwork. It adopts classic coinage techniques such as mirror surface, sandblasting, and multi-level sandblasting. The combination of aesthetics has important commemorative significance and artistic value.
The commemorative coin issued this time is my country’s seventh set of aerospace-themed gold and silver commemorative coins. Prior to this, the 40th anniversary of the establishment of China’s aerospace, the successful first manned space flight, the first lunar exploration flight, the first space walk, and the opening of the Beidou satellite navigation system Important aerospace events such as the operation and the success of the first moon landing have issued precious metal commemorative coins, bearing in mind China's aerospace exploration achievements in climbing the technological peak, expressing the astronauts' scientific dreams and forge ahead attitude, and demonstrating the Chinese people's cultural confidence and romantic feelings.
As of August 30, the rover had traveled a total of 1064 meters south of the landing site.
At present, the rover is in good condition and has sufficient energy. It will continue to follow the high-efficiency detection mode of "seven-day cycle, one-day planning, daily detection", and drive to the ancient sea-land junction in the south to obtain richer scientific exploration. data.
The orbiter has been in orbit for 403 days and is about 392 million kilometers away from the earth. On August 24, a high-resolution camera was used to image the landing area, and a 1-meter resolution image was obtained. The image shows a clear track of the rover.
At present, the distance of the earth fire is gradually approaching the farthest (about 395 million kilometers). In mid-to-late September, the earth and Mars will travel to both sides of the sun, and the three will be almost in a straight line, and the probe will enter the solar transit phase.
During the transit, due to the influence of solar electromagnetic radiation interference, the device-to-ground communication is interrupted, the orbiter and the rover will switch to safe mode and stop the detection work.
After the solar transit, the orbiter will select the opportunity to enter the remote sensing mission orbit to carry out global remote sensing exploration of Mars, while taking into account the relay communication of the Mars rover's expansion mission stage.
