China's first Mars exploration mission successfully landed on Mars. what do you think?

Earlier, The Paper reporter learned from the National Space Administration that the scientific research elite team confirmed according to the telemetry signal sent back by the "Zhu Rong" rover that on May 15, Tianwen No.1 landing patrol successfully landed in the landing area of the selected number plate in the southern part of the Martian utopia plain, and the first daily mission of Mars exploration in China was successfully completed.

At 1 am, Tianwen-1 probe lowered its orbit in parking orbit and maneuvered freely before Mars entered orbit. At about 4 o'clock, the landing patrol left the enclosure. After about three hours of sailing, it entered the Martian air. After about 9 minutes of deceleration, hovering to avoid obstacles and buffering, it successfully landed in the landing area of the selected number plate. After the two devices were separated for about 30 minutes, the track around the device rose and returned to the parking track to provide wireless relay communication for the landing patrol device. After that, the "Zhou Tai" rover will conduct overall imaging, self-inspection, driving out of the landing site and conducting patrol detection.

In 20 16, China announced the first daily mission of Mars exploration, and the project was approved. According to the once-a-day mission, the project completed the flying around, landing and patrol of Mars, carried out international and comprehensive flying around exploration of Mars, and conducted regional patrol exploration on the surface of Mars. Tianwen-1 detector consists of a shell and a landing patrol, which includes Zhou Tai fire engine and its entry cabin. Since the probe was successfully sent on July 23, 2020, it has completed 1 space maneuver and adjusted four times in the middle of ground fire transfer. On February 65, 438+00, Mars was successfully captured and entered the elliptical ring fire orbit, becoming the first synthetic Mars communication satellite in China.

On February 24th, 20021year, Tianwen No.1 probe successfully implemented the third near fire braking system. After entering the Mars docking orbit with a cycle time of two Mars days, it made a worldwide remote sensing exploration of Mars, made a detailed investigation of the landing area with the selected number plate, and detected and analyzed the geological structure, dust weather and so on. Prepare for landing on Mars. In the whole process of daily mission implementation, China National Space Administration has carried out relevant cooperation projects with ESA, Argentine, French, Austrian and other international space agencies and China Space Organization. At present, the distance between the detector and the earth is about 320 million kilometers.

According to NASA, Mars exploration is risky and difficult. The daily task of exploration has encountered challenges such as the natural environment in interplanetary space, the thin air on Mars, the geological structure on the surface of the fire, and the harm of long distance and long delay. There are some problems in the landing process, such as the uncertainty of natural environment, complicated landing procedures and the inability to interfere with the road surface. Tian Wen-1' s daily mission has improved the core technologies such as the speed sending of the second universe, the communication between interstellar flight and measurement and control technology, and the soft landing of extraterrestrial planets, and completed the first landing of extraterrestrial planets in China, which is another milestone with positive significance in the development trend of China's space engineering.
