Tian Wen 1 successfully circled Mars. How was it perfectly captured by Mars?

First,? Tian Wen No.1? The scientific goal of:? Tian Wen No.1? Task * * * has a payload of 13. The seven instruments on the orbiter include two cameras, Mars underground detection radar, Mars mineralogy spectrometer, Mars magnetometer, Mars ion and neutral particle analyzer and Mars high-energy particle analyzer. The six instruments on the Mars vehicle include a multi-spectral camera, a terrain camera, a Mars underground detection radar, a Mars surface composition detector, a Mars magnetic field detector and a Mars meteorological monitor.

These payloads should achieve the following scientific objectives:

(1) Map the morphology and geological structure of Mars;

(2) Investigate the soil characteristics and water-ice distribution on the surface of Mars;

(3) analyzing the material composition on the surface of Mars;

(4) Measuring the climate and environmental characteristics of the ionosphere and the surface of Mars;

(5) Explore the physical field (electromagnetic field, gravitational field) and internal structure of Mars.

Second,? Tian Wen No.1? The success of the detector and its influence on the world;

In the longer term, the earth is likely to be destroyed by the impact of extraterrestrial planets in the future. Therefore, some scientists think that we can first transform Mars into a second home suitable for human habitation, and then immigrate to Mars. To this end, it is necessary to gradually understand Mars in an all-round and in-depth way, so as to lay a good foundation and make preparations for transforming Mars and building a Mars base. Therefore, exploring the significance of Mars is of great significance to the world and all mankind.

Third, it was perfectly captured by Mars:

Since the successful launch on July 23, 2020, Tian Wen-1? The probe has flown for 202 days and completed 65,438+0 deep space maneuvers and 4 mid-course corrections. When reaching Mars, the flight mileage is about 475 million kilometers, about10.92 million kilometers away from the earth, and the one-way communication between the instrument and the ground is delayed by about 10.7 minutes. All systems are in good condition. Follow up? Tian Wen No.1? After several orbital adjustments, it will enter the parking orbit of Mars and conduct pre-selected landing zone exploration. It is planned to land on Mars in May-June, 20021,and carry out patrol exploration. When this Mars exploration mission was captured, the target orbit of the probe was only 400km away from the nearest place of Mars. Now? Tian Wen No.1? It only takes seven minutes to land on Mars.

2021February 5 at 20: 00, Tian Wen-1? The ignition work of the probe engine successfully completed the fourth mid-course correction of the ground fire transfer section to ensure that the Mars capture was carried out as planned. Nasa announced simultaneously? Tian Wen No.1? The first image of Mars was obtained about 2.2 million kilometers away from Mars.

2021February 10/9: 52, China's first Mars exploration mission? Tian Wen No.1? The detector implements near fire capture braking, and the orbiter ignites at 3000N for about 15 minutes. The probe successfully entered the near fire point, with an altitude of about 400 kilometers, a period of about 10 earth days and an inclination of about 10? The Great Ellipse Ring Fire Orbit became China's first artificial Mars satellite, realizing? Round and round? Step one? Around? A successful goal around mars. After the first Mars exploration mission entered the Mars capture stage from the ground fire transfer stage, Tian Wen No.1? The medium-resolution camera, high-resolution camera, magnetometer, mineral spectrum analyzer, ion and neutral particle and energy particle detectors carried by the circulator will begin to work one after another to carry out multi-dimensional exploration of Mars.
