On the months of March 2022 the week of 20^th March 2022 天问一号飞運騎遊達达3亿CNSA – China National Space Administration – ESA – European Space agency Belt and road initiative mars mission…first Mars exploration mission, Tianwen- Martian Probe One sent back stunning images of the Half Earth Mass size of the Rustic Planet Mars in which show stunning Martian landscape with its iconic polar caps of either southern or northern .. With its timeless Stunning Mars Photography. Tianwen-1″ returned high-resolution images of the Mars inspection area

Figure 1 The image of the inspection area of ”Zhurong” taken by a high-resolution camera

A few days ago, the “Tianwen No. 1” orbiter passed over the inspection area of the Mars rover again, and took a 0.5-meter resolution image of the “Zhurong” inspection area. As of March 24, 2022, the “Zhurong” rover has been working on the surface of Mars for 306 Martian days and has traveled 1,784 meters in total. The “Tianwen-1” orbiter has been in orbit for 609 days and is 277 million kilometers away from the earth. Both are operating normally.

The “Zhurong” rover also sent back selfies from the surface of Mars. Compared with the photos taken just after landing, it can be seen that a thin layer of dust has accumulated on the surface of the rover. At the same time, according to the telemetry information of the rover, the power generation efficiency of the solar wing is affected to a certain extent, but the energy is still sufficient. In order to cope with the dust coverage, the solar wing of the Mars rover has been specially designed, and various measures can be taken to deal with the problem of the reduction of power generation efficiency caused by the sand and dust.

The Martian dust storm will directly affect the energy acquisition of the Mars rover, which has always attracted much attention. The engineering team continued to monitor the Martian sand and dust weather through images obtained by the medium-resolution camera of the “Tianwen-1” orbiter, and found that from late January this year, obvious wind and sand activities began to appear in the area north of 60 ° N latitude on Mars. It can be seen from the figure below that a local sandstorm occurred in this area in February this year, and typical features were covered by a large amount of sand and dust, making it difficult to distinguish.

At present, the northern hemisphere of Mars has begun to enter autumn. According to the analysis of previous detection data, autumn is the season of frequent occurrence of dusty weather on Mars, but no obvious dusty weather has been observed in the inspection area of ”Zhurong”.

The “Tianwen-1” orbiter continues to carry out global remote sensing exploration of Mars, and focuses on typical landforms and geological units such as craters, volcanoes, canyons, and dry riverbeds, and obtains high-resolution images. On March 7 this year, the American “Perseverance” rover was photographed while imaging the “Jezero” crater, which is currently located about 200 meters southeast of its landing site.

Also on the 4th February 2022 Sunday the Winter Olympics begin! A blessing “falls from the sky” across 320 million kilometers! Previously, the mascots of the Beijing Winter Olympics and the Winter Paralympics, Bing DunDun and Xue RongRong, landed on Mars on Tianwen-1, and took a group photo with the Zhurong Mars rover, which was a dream ..

Also that Day the Tianwen-1 probe, the five-star red flag and the emblems of the Beijing Winter Olympics and Paralympic Games took a selfie in the same frame.

Beijing is the first city with both summer and winter Olympics, and Tianwen-1 is China’s first interplanetary exploration mission, sending the mascots and logos of the Winter Olympics and Paralympics to Mars. The Chinese expression is the Chinese nation’s advocacy and pursuit of faster, higher, stronger and more united.

This set of “cosmic-level” photos returned from Mars orbit was taken by the “selfie” camera carried by the Tianwen-1 probe. This group of photos is not only a “highest” Winter Olympics gift to friends on the ground, but also a highlight witness to the world’s shared Olympic moments!

As of February 4^th2022, Tianwen-1 has been in orbit for 561 days, and the Zhurong rover has worked for 259 Martian days, traveling a total of 1,537 meters. Both the orbiter and the rover are in good condition and operating normally.

On the eve on 31^st January 2022 in which on the 1^st February 2022 of the Chinese Lunar New year Spring Festival in the Year of the Tiger, the Tianwen-1 probe sent back a set of selfie videos from Mars orbit to extend New Year wishes to the people of the whole country- China – People’s Republic of China and the Chinese Communities . On the 29th of the twelfth lunar month last year (February 10, 2021), Tianwen-1 arrived on Mars and successfully implemented capture and braking. It became my country’s first artificial Mars satellite, and started a scientific exploration journey to the red planet. a lunar year.

The video is a video of the Mars group photo taken by the probe.

The video was shot by the “selfie” camera carried by the Tianwen-1 surround. The camera is installed at the end of the “selfie stick”. This selfie tool is designed to monitor and evaluate the status of key components outside the surround. In the video The orbiter’s 3000N engine, propellant storage tank, attitude control engine and other components are in good condition. The five-star red flag shining in the Mars orbit is particularly bright. During the attitude adjustment process, the angle of the sun’s illumination changes significantly. When flying over the north pole of Mars, the ice cap below was photographed.
The “selfie stick” uses a special shape memory composite material, which is folded and folded before launch. After entering the orbit of Mars, the folded part is heated to a certain temperature, and the “selfie stick” gradually returns to a straight state. The “selfie stick” weighs only 0.8 kilograms and is 1.6 meters long when unfolded. The camera installed at the end can effectively complete various monitoring tasks.

As of January 31, 2022, Tianwen-1 has been in orbit for 557 days, about 325 million kilometers away from the earth, and the light travel time is about 18 minutes. The Zhurong rover has worked for 255 Martian days and travelled a total of 1524 meters. At present, the Tianwen-1 mission has returned a total of about 600GB of original scientific data, and the two devices are in good condition and operating normally

Orbiter and Mars photo

This set of images includes a photo of the orbiter and Mars, a close-up of the orbiter, the North Pole ice cap of Mars, and the “Zhurong” rover shooting fire landforms, etc., showing the operating status of the orbiter, the “Zhurong” rover, and the acquired surface of Mars form.

In Figure 1, the orbiter is flying over the north pole of Mars. The orbiter body is golden, the directional antenna for high-speed data communication with the ground is silver (under the orbiter body), and the solar wing is in good condition. The white area on Mars is the “ice” sheet covering the North Pole. Unlike the ice at the two poles of the Earth, the “ice” of Mars is composed of dry ice (solid carbon dioxide) and water ice. The dark area below Mars is the Olympia Shabo of Mars, the bright circular crater in the upper left corner is named Korolev Pit, and the remaining red and dark areas are bare ground.

In Figure 2, the solar wing on the side of the orbiter is fully deployed and the attitude is stable. An unfolded subsurface detection radar antenna is parallel to the solar wing, and the magnetometer extension rod extends to the upper left of the surround.

Mars Arctic Ice Sheet

Figure 3 shows the Martian North Pole ice cap, the bedding is clearly visible. After years of deposition and ablation, it presents a spiral landform composed of a white ice layer centered on the pole and bare ground.

Figure 4 is a mosaic of 3 images acquired by the “Zhurong” Mars rover recently using a navigation terrain camera. In the figure, we can see typical Martian topography such as ring craters and rocks. As of December 31, 2021, the Tianwen-1 orbiter has been in orbit for 526 days, and is currently about 350 million kilometers away from the Earth. The communication delay is about 19.5 minutes. 1400 meters. At present, the Tianwen No. 1 mission is carrying out detection and related tests as planned, and a total of about 560GB of raw scientific data has been returned. The two devices are in good condition and operating normally.

On the months of December 2021 天问一号飞運騎遊達达3亿CNSA – China National Space Administration – ESA – European Space agency Belt and road initiative mars mission…first Mars exploration mission, Tianwen- Martian Probe One …….祝融号Zhu Rong” Zhang Rongqiao, chief designer of China’s first Mars exploration mission, was selected as one of the ten greatest figures of the year in Nature

At 0:00 on December 16^th 2021 Thursday, Hong Kong SAR- Beijing time, the international authoritative scientific magazine “Nature” published the top ten figures of 2021, and Zhang Rongqiao, the chief designer of my country’s first Mars exploration mission, was selected. On May 15, 2021, China’s Mars rover “Tianwen One” successfully landed on the pre-selected landing zone on the surface of Mars. China became the second country in the world to successfully land on Mars and deploy a Mars rover. After the “Zhurong” Mars rover sent back telemetry signals, the flight control center in Beijing lit up a festive red screen, and the engineer excitedly shouted “Hello, Mars!” Zhang Rongqiao took off his glasses silently at this time, tears in his eyes.

The character of the year in “Nature” describes Zhang Rongqiao as “Mars explorer”. Mars is a space nightmare for many countries. So far, the overall success rate is only about 50%, and the success rate for landing missions is only a little over 40%. China’s first Mars exploration mission completed the three major goals of Mars orbiting, landing and patrolling. It is even more difficult and risky. Behind the steadily accomplishing the three goals is the effort to “grind a sword in ten years.” “In order to win today’s first battle, we started planning 10 years ago. We have worked hard for 6 years, held at the launch site for 110 days, and held at the Beijing Aerospace Flight Control Center for 202 days. The first victory was to orbit Mars. After that, I held on for another 93 days to this day. What is the purpose? It is for today’s final victory!” Zhang Rongqiao said excitedly at the flight control center on May 15th.

At a press conference held by the National Space Administration in Beijing on June 12, Zhang Rongqiao said, “Achieving a circumnavigation in one step means that the development is more difficult. To put it more plainly, the possibility of failure increases. For our developers, we can bear it. Zhang Rongqiao said. Fortunately, there is the correct leadership of the Party Central Committee, and there are government organizations at all levels, especially the powerful organization of the National Space Administration, including the Aerospace Science and Technology Corporation, the Chinese Academy of Sciences, and the launch site and measurement and control The competent departments have vigorously coordinated, and the fire detection research and development personnel have worked hard and overcome difficulties. “To put it more bluntly, it is the fire-detector’s vigor. We succeeded today. Looking back, the choice of this technical route is very correct.” Zhang Rongqiao said that overall it is more cost-effective, especially in terms of technology. It can achieve leapfrog development and make my country enter the world’s advanced ranks in the field of planetary exploration in a relatively short period of time. “Therefore, we said that the first Mars exploration mission was based on China’s national conditions and embarked on a path of aerospace development with Chinese characteristics.”

In the future, China will implement deep space exploration missions such as Mars sampling and return missions, near-Earth asteroid sampling and return and main belt comet orbiting missions, Jupiter system orbiting and planetary crossing missions. “Looking up at the stars and keeping your feet on the ground” are two words that Zhang Rongqiao likes very much. He said: “This is precisely what society needs for each of us, and it is a way for us to settle down in society. We need to stand on the present and look to the future.” Zhang Rongqiao Said: “Our knowledge and understanding of the universe is still very superficial. We should see that the world beyond the cradle is infinitely vast. Innovation never ends.”

The Top Ten People of the Year in Nature are records of important scientific developments and events this year, as well as some of the key figures and their colleagues. The top ten figures were selected by the editors of Nature and gathered individuals who influenced some of the most important scientific events in 2021.
