Tianwen 1 successfully landed on Mars, what did it do on Mars?

Tianwen No. 1. Successfully landed on Mars, which is China's first exploration mission to Mars. After more than 2,000 seconds of flight, the probe was successfully sent into the predetermined orbit, starting the first Mars exploration.

The trip is also a big step forward for China's extraterrestrial exploration. In fact, we are all curious about what it can do on Mars. Let's find out:

1. Resend signals to Earth and maintain communication with the rover.

There is a directional antenna, which can make the signal as far as possible towards the earth, maintain communication with the earth, and at the same time, it can also transmit the real-time situation of Mars to the earth with cameras, sensors, shooting and feeling, leaving valuable image records about Mars.

2. The study of the landform and characteristics of Mars is called "payload" on the hard work of the rover. There are five main tasks: first, to study the geomorphological and geological structure characteristics of Mars; 2. To study the soil characteristics and water ice distribution on the surface of Mars; 3. Study the material composition of the Martian surface; 4. Study the ionosphere of the Martian atmosphere.

and surface climate and environmental characteristics; 5. Study the physics and internal structure of Mars.

3. In addition to the above five aspects of research, the Martian surface exploration also needs to detect the magnetic field on the surface of Mars to detect whether there is a magnetic field on the surface of Mars, the strength and direction of the magnetic field, in fact, Mars can be further detected through the analysis of the magnetic field.

local structure of the interior; Mars meteorological probes to detect the temperature, air pressure, wind direction and strength of its surface. There will also be a recording of the surface of Mars, which is also very curious, and maybe the Martian recording will be made public in the future, and we can hear the sound from Mars on Earth. This is also the magic and charm of scientific research!

In fact, a variety of instruments on the Mars rover are designed to allow us to better explore and understand the Martian environment, and the scientific research on Mars is also very rich. At the same time, we also wish "Zhu Rong."

"No. " was able to successfully complete the mission and return successfully as soon as possible.

After arriving on Mars, he first slowly opened his protective airbag, as well as various explorers and monitoring screens, just to transmit information to the monitoring personnel on Earth, and then walked slowly on it.

The main purpose is to study the geological structure of the land and active surface on the surface of Mars, as well as the distribution of the soil and waterside of Mars, as well as the material structure of the surface of Mars, as well as the climate and environmental characteristics of the line of fire, and to study the physical field and internal structure of Mars.

It should be to survey the terrain, because Mars may have life, so be sure to survey the terrain to detect accurately.

Tianwen-1 Mars roverThe date of the successful landing on Mars is May 15, 2021. At about 1 o'clock in the morning, the Tianwen-1 probe.

Orbit demotion in the parking orbit and maneuver to Mars into orbit.

At about 4 o'clock, the landing rover separated from the orbiter, and after about 3 hours of flight, it entered the Martian atmosphere, and after about 9 minutes of deceleration, hovering obstacle avoidance and buffering, it successfully made a soft landing in the pre-selected landing area. About 30 minutes after the separation of the two vehicles, the orbiter ascends and returns to the parking orbit to provide relay communication for the landing rover. Subsequently, the "Zhurong" Mars rover.

The global imaging of the landing site, self-inspection, departure from the landing platform, and patrol detection will be carried out sequentially.

The difficulty of Mars exploration.

Mars exploration is risky and difficult, and the exploration mission faces the interplanetary space environment, the thin atmosphere of Mars, and the terrain and landform of the fire surface.

At the same time, due to the influence of long distance and long delay, there are difficulties in the landing stage, such as uncertain environment, complex landing procedures, and inability to intervene on the ground. The Tianwen-1 mission broke through the second cosmic velocity.

Key technologies such as launch, interplanetary flight, TT&C communication, and soft landing on an extraterrestrial planet have achieved China's first extraterrestrial planet landing, which is China's aerospace industry.

Another milestone of great significance in development.

Tianwen-1 is the crystallization of China's wisdom and strength. The successful landing on Mars shows that China's aerospace technology development has reached a new level. Wang Chuang, the chief engineer of Tianwen-1, said that Tianwen-1's successful landing on Mars is completely in line with the plan that has been fully prepared.

Our top leaders gave sincere congratulations and greetings. The outside world also congratulated and praised China's Mars exploration mission as a great and important achievement of mankind.

You know, landing on Mars is not an easy task, countries have carried out a total of 44 times before, and the Mars exploration program has only succeeded 19 times. Landing is very risky, and there are only 9 probes that have successfully landed on Mars. Tianwen-1 was on Mars, and the landing was successful, leaving a mark of China on Mars.

The process of landing is very complicated, from separation to landing, it only takes 9 minutes, and there are many links in between, which complement each other. There are many influencing factors, such as a thin atmosphere on the surface of Mars, occasional sandstorms, windstorms, etc., which are very unstable. When landing, the lander rubs against the atmosphere, which will produce high temperatures, so with the design of heat insulation, the engine is limited, the volume becomes smaller, and the engine must be stronger to achieve the thrust standard.

In addition, the entire process of landing is controlled by the probe autonomously, and human intervention cannot be made. Our space development has been full of ups and downs and is full of hope.

The successful landing of Tianwen-1 on Mars represents a major progress in China's space technology, which is also a great progress in human space exploration, marking that China has become the second country in the world to land on Mars, and has achieved a great breakthrough from the Earth-Moon system to the solar system.

On May 15, 2021, the Tianwen-1 landing rover successfully landed in the pre-selected landing area in the southern part of the Martian Utopia Plain, marking the complete success of China's first Mars exploration mission on Mars. This will achieve a technological leap forward for China in the field of deep space exploration. Deep space exploration will promote the comprehensive development of space science, space technology and space applications, and make greater contributions to serving the overall development of the country and enhancing the well-being of mankind.

The great significance behind the successful landing of Tianwen-1 on Mars is that Tianwen-1 is the crystallization of China's wisdom and strength, and its successful landing on Mars shows that China's aerospace technology development has reached a new level; It is also the true embodiment of the spirit of "independence and self-reliance" carried forward by China's astronauts, and has become a new milestone in China's aerospace science and technology, which is of great significance to China, a symbol of China's scientific and technological progress, and also boosts the self-confidence and public pride of the Chinese.

Behind Tianwen-1 means that China has become a member of the first phalanx alongside the United States in the field of aerospace technology, which will greatly enhance China's international influence and is an important symbol of China's real strength. Zhurong symbolizes igniting the fire of China's interstellar exploration and guiding astronauts to constantly surpass themselves and pursue their dreams and stars.

The successful landing of Tianwen-1 has made China the second country to land on Mars, which shows that China's aerospace technology has reached a higher level and demonstrated China's strong national strength

Recently, the news that "Tianwen-1 successfully landed on Mars" has aroused heated discussions among the majority of netizens, and there has been a lot of uproar on the Internet. So, what is the significance of Tianwen-1's successful landing on Mars? First, this landing broke the situation of the United States being the only one on Mars, and became the second country to be able to run a Mars rover on it.

Second, this is a milestone step for China's space flight, because this is the first time that China has landed on Mars, and it has been a successful landing. Third, it has raised human awareness, made people know more about the secrets of Mars, and can improve technology. So what's going on?

Let me share my thoughts with you.

One. First of all, the landing of China's Tianwen-1 on Mars is to break the situation of the United States' dominance, and it has always been the only United States running the Mars rover on it, and now it is not only the United States, China has also joined the Mars exploration team, and in the future, you will be able to have more secrets about Mars to learn by yourself. <>

Two. This is a milestone step for China's aerospace Then, this is a milestone step for China's aerospace, before that, China has never sent a Mars probe to Mars, and this time is the first time, and it is also the most difficult one, with this experience, it will be better in the future, send more Mars probes to explore more efficiently. <>

Three. Finally, this also improves human cognition, and the understanding of Mars will become more, and through such activities, we can improve technology, cultivate talents, and strengthen our country's space technology. <

For our country, this proves that our country has its own independent technology, so it can land on Mars, and with our national status, it will be respected by other countries in society.

It is of great significance, which means that our country's science and technology and scientific and technological products have reached a relatively leading position, and it can also better explore Mars.

It is of great significance that we have a new understanding of Mars, and we are learning more and more about outer space.

It can improve China's scientific and technological strength, and it is very meaningful for China, and it can improve China's comprehensive national strength.

For our country, our country will have the first-hand information of Mars, which will improve our country's international visibility and discourse.

Tianwen-1 successfully landed on Mars, and in the process of landing, Tianwen-1 underwent a de-orbit in the parking orbit, maneuvered to Mars into orbit, and then the landing rover was separated from the orbiter, and after about 3 hours of flight, it entered the Martian atmosphere, and after about 9 minutes of deceleration, hovering obstacle avoidance and buffering, it successfully made a soft landing in the pre-selected landing area.

The reporter learned from the China National Space Administration that the scientific research team confirmed according to the telemetry signal sent back by the "Zhu Rong" Mars rover that at 7:18 on May 15, the Tianwen-1 landing patrol team successfully landed in the pre-selected landing area of the Utopia Plain in the south of Mars, and China's first Mars exploration mission successfully landed on Mars. At 1 a.m., the Tianwen-1 probe lowered its orbit in a parking orbit and moved towards Mars into orbit. At around 4 o'clock, the landing patrol broke away from the encirclement and, after about 3 hours of flight, entered the Martian atmosphere.

After about 9 minutes of deceleration, hovering obstacle avoidance and buffering, it successfully landed in the pre-selected landing area. After about 30 minutes of separation, the orbiter lifted the orbit and returned to the parking track to provide relay communications for the landing patrol. Subsequently, the "Zhu Rong" rover will carry out global imaging of the landing site, self-inspection, off-platform and patrol exploration in turn.

China's first Mars exploration mission was officially approved in 2016. It is planned to orbit, land and patrol Mars in a single mission, conduct global and integrated exploration around Mars, and conduct regional patrol exploration on the surface of Mars. The Tianwen-1 probe consists of an orbiting and landing patrol, which includes the Mars rover Zhu Rong and his entry module.

Since its successful launch on July 23, 2020, the probe has completed one deep-space maneuver and four mid-course corrections during the ground-based fire transfer phase. On February 10, it successfully captured Mars and entered the large elliptical ring orbit, becoming China's first artificial Mars satellite. On February 24, 2021, Tianwen-1 successfully implemented the third near-fire braking, and after entering the Martian parking orbit with a cycle of 2 Martian days, it carried out a global remote sensing exploration of Mars, and conducted a detailed investigation of the pre-selected landing area, and carried out detection and analysis of the terrain, sand and dust weather.

Thus preparing for the landing on Mars. During the mission, the China National Space Administration cooperated with ESA, Argentina, France, Austria and other international space organizations and national space agencies on relevant projects. At present, the probe has been flying in space for 295 days, about 100 million kilometers from the Earth.

Expeditions to Mars are risky and difficult. Exploration missions face challenges such as the interstellar space environment, the thin atmosphere of Mars, and the fire-surface terrain. <>

Since its launch, the orbiter has gone through the flight process of the earth-fire transfer section, the braking capture section, and the ring fire flight section, successfully completed the Mars braking capture, and completed the orbiting and exploration targets in the three major goals of "orbiting, landing, and patrolling" On July 27, 2020, the orbiter looked back at the Earth at a distance of about 1.2 million kilometers from the Earth, and used the optical navigation sensor to image the Earth and the Moon, and obtained a clear photo of the Earth and the Moon. In this black-and-white group photo, the Earth and the Moon are both in the shape of a crescent moon, reflecting each other in the vast universe.

China's first Mars exploration mission, the Tianwen-1 probe, landed in the pre-selected landing area in the southern part of the Martian Utopia Plain, leaving a Chinese imprint on Mars for the first time, and taking an important step in China's interstellar exploration journey. Subsequently, the Zhurong Mars rover will carry out global imaging of the landing site, self-test and leave the landing platform and carry out patrol exploration.
