All systems of the probe are in good condition. previously, tianwen-1 acquired its first image of Mars at a distance of about 2.2 million kilometers. in the picture, the landmarks of Mars, such as the asidalia plain, the kreiser plain, the meridian plateau, the skiaparelli pit, and the longest Canyon, sailor's Valley, are clearly visible.

The reporter learned from the National Space Administration yesterday that the total flight distance of the "tianwen-1" probe is more than 450 million kilometers, about 170 million kilometers away from the earth. It is expected that around February 10, the "tianwen-1" probe will stop near fire and start its journey around Mars. Mars is the fourth closest planet to the sun, which is close to the earth and has the most similar environment, so it has become the preferred target for human exploration. On July 23, 2020, China successfully launched the "tianwen-1" probe with the long March-5 yao-4 carrier rocket at Wenchang space launch site, taking the first step of independent interplanetary exploration. According to the plan, the Mars exploration mission will realize the "around, around, and on tour" of Mars_ blank" href=" https://news.163.com/news/search?keyword=%E7%9D%80%E9%99%86 "> landing < / a >, Mars surface inspection. The total mass of the 5-ton tianwen-1 spacecraft is composed of a orbiter and a landing rover, including an entry module and a Mars rover. since the start of the journey to Mars, the "tianwen-1" probe has successfully completed the Earth Moon group photo, the probe's "self photo", three midway corrections, deep space maneuver, and payload self-test. At present, the attitude of the probe is stable, and all systems are working normally. The reporter learned that the "tianwen-1" probe will stop near fire around February 10, and then start a two-and-a-half month tour around Mars to make a preliminary exploration of the land area. It will land when the weather conditions are good. The landing area is chosen in the utopian plain of the northern hemisphere of Mars. experts from the Fifth Academy of China Aerospace Science and technology group told reporters that the Mars exploration mission is extremely difficult, because the farthest distance from the earth to Mars is about 400 million kilometers, the communication delay is more than 20 minutes, and the Mars atmosphere is thin and the terrain is complex, so there are risk points in the near fire braking, buffer landing and other links of the probe. Many countries have carried out Mars exploration missions before, and the success rate is only about half. "tianwen-1" is also equipped with China's first Mars rover. There are ten shortlisted names for the Rover: Hongyi, Qilin, Nezha, Chitu, zhurong, qiusuo, fenghuolun, zhumeng, Tianxing and Xinghuo. The final name of China's first Mars rover will be announced on the occasion of tianwen-1's landing on Mars. tianwen-1 Mars probe is expected to implement near fire braking around February 10 source: China News Network China News Agency, Beijing, January 6 (Guo Chaokai) according to China Aerospace Science and Technology Group on the 6th, the tianwen-1 probe will implement the near fire brake and enter the annular fire orbit after it approaches Mars in more than a month (around February 10, 2021). By 6:00 on January 3, China's first Mars exploration mission, tianwen-1 Mars probe, had been in orbit for about 163 days, with a flight distance of more than 400 million kilometers, a distance of nearly 130 million kilometers from earth and 8.3 million kilometers from Mars. the tianwen-1 mission is the first step of China's independent interplanetary exploration, which will realize "circling, landing and patrolling" to Mars through a single launch, namely Mars circling, Mars landing and fire surface inspection. The total weight of tianwen-1 is about 5 tons. It is composed of a orbiter and a landing Rover. The landing Rover mainly includes an entry module and a Mars rover. At present, the orbiter has completed the third on orbit self-test, and each system works normally. the distance between Mars and the earth changes periodically, about 50 million km at the latest and more than 400 million km at the farthest. When WEN-1 arrived near Mars on the same day, it was about 190 million kilometers away from the earth, with a total flight distance of 470 million kilometers. According to the plan, the tianwen-1 probe will implement the near fire braking, commonly known as "braking", after it approaches Mars in more than a month (around February 10 this year), and then it will be captured by Mars and enter the annular fire orbit to become a satellite of Mars and prepare for landing on Mars.
