Monday, April 19, 2021 will commemorate the first day in the atmosphere of a planet other than ours, the day of the invention of a motor-fitted and controlled mechanical ingenuity. Tuesday. And this video, taken by the rover of diligence, was posted about 65 meters away, erasing this moment.

The Chinese space agency (CNSA) has released the first two images of the Jurong rover purchased from Mars. Animated GIF It shows Separation Thayvem-1 lander and study. The definition of images is lower than we are accustomed to NASA With its Mars missions, but the most powerful camera has yet to deliver its images. Meanwhile, the Chinese are discovering Mars with their own tools!

A dull and dilapidated landing site

The first shot, taken in black and white, was taken by one of the obstacle avoidance cameras installed on the front of the rover. This photo shows the sorted curve that Jurang uses to land on Mars soil. Surprisingly, the view given to the Chinese rover is flat terrain, almost tireless. A dull and dilapidated floor. Suitable for smooth landing. In the second picture Color Obtained by the navigation camera mounted on the back of the rover. This shows that the solar panels and rover antenna are expanding and in very good condition. Mars dust has not yet settled in it. Pebbles of all sizes are clearly visible in the picture.

Then நிலா, China is the second country to land on Mars and successfully land a rover on the Red Planet. What a formidable technical achievement and a performance first!

For the first autonomous mission to Mars, China has achieved a formidable technological achievement. That night, with the successful landing of Jurong, it became the second country after the United States to successfully land a rover on Mars. The former Soviet Union succeeded in landing a lander on March 3, 1971, but communications were cut off 20 seconds after it landed.

In the named wide plain, the rover landed at the destination Utopia Planitia

The rover landed smoothly at a distance of 40 km from the target point Utopia Planitia, A vast plain locatedNorthern Hemisphere In March. Landing integrations in the Utopia Planetia region: 109.9 m and 25.1 n.

Landing on Mars is easy. Since the beginning of the study of this planet, many European, Soviet and American missions have ended in failure. FailureSchiaparelli Lander In 2016, the first European test Thing, Underscores this difficulty in landing on the Red Planet. In March 2011, China attempted to shipChinese Orbit Yingguo-1 During a joint trip with Russia. But sonde Russian Popos-Grund, The ship that was Yingluck-1, boarded in the Pacific Ocean and crashed again several months later.

A trip to Mars should last 90 days

Weighs about 240 Kilograms, Jurong has to work for about 90 days. Equipped with six motorized wheels that allow it to move like a crab, the Jurong can travel up to 200 meters per hour. It has six tools, including a camera Laser Very similarTool Chemcom American Rover Curiosity. It includes optical cameras, a radar to study the soil, a spectrometer, a Magnetometer And a meteorological station (temperature, pressure and measurements Vent Especially). Will produce its four solar panelsEnergy Necessary for its operation. Data can also be transmitted by the Tianwen-1 orbiter or by probe Mars Express From the European Space Agency if China so requested.

Chinese rover Jurang will land on Mars tonight!

Will China become the third country to land safely on the surface of Mars after the former Soviet Union and the United States? The answer tonight with the arrival of the Red Planet of the rover of the Tianwen-1 mission.

If all goes according to plan, Jurong Rover is expected to enterAtmosphere Start landing on Mars 23 hours 11 minutes (UTC) Friday evening. More precisely in the southern partUtopia Planitia, The Chinese space agency has not yet released the coordinates. This part of the Northern Hemisphere is one of the most difficult places to land on Mars. For registration, inquire Viking2 NASA landed in the northern hemisphere in 1976Utopia Planitia.

Less difficult is not easier

The Jurong Rover will face the famous seven-minute ordeal needed to land on Mars. By selecting part ofUtopia Planitia, The people in charge of the task were given every opportunity to succeed in getting down to safety. This area is low in altitude, which gives enough time to brake for inspection, and this southern partUtopia Planitia The largest areas are very flat and the lowest hills are only a few hills sable And large rocks. The destination landing ellipse is about 100 km long and about 20 km wide.

To land on Mars, Jurong will use a thermal shield, a Parachute More than 15 meters in diameter and retro-rockets. Before landing, the lander will use its navigation system to find the most suitable location. A Sensor The laser will film the ground in three dimensions and a camera will compare it with the images obtained from the study to avoid the most dangerous obstacles and to find a clear place for landing. The technologies implemented in the Mars lander are based on tradition Chang Lunar Journeys, For engine and navigation area and drone program Shenzhou, For heat shield and parachute system.

FailureSchiaparelli Lander In 2016, the first European test in this regard underscored all the difficulties of landing on Mars. Currently, only Americans have successfully landed on Mars. The former Soviet Union succeeded in landing a lander on March 3, 1971, but communications were cut off 20 seconds after it landed.

Who was the first Chinese rover to land on Mars?

Article by Remy DeCourt published on 05/04/2021

If on the Red Planet, NASA occupies the front of the media scene with its exploits Helicopter, China should steal the show soon. In two or three weeks, or a few days, the Jurong rover is expected to land on Mars. He is currently under investigation for Tianwen-1, which is engaged in the task of finding the best place to land.

If all eyes are on the task Diligence And thisIngenious helicopter From NASA, let’s not forget that China is preparing to land on the Red Planet. In Around the circular path Orbiting the planet from February 10, the Chinese Study Tianwen-1 The Jurong Rover is set to land on a date not yet announced, but it is expected to be from mid-May to early June. If all goes according to plan, China will become the second country after the United States to land a rover on Mars. Note that the former Soviet Union succeeded in landing a rover on the Red Planet in 1971, but the latter only ran for a few ten seconds (March 3).

For a safe landing in the southern part of Jurong RoverUtopia Planitia, Requires a detailed analysis of its landing site. In fact, you need to know whether the Chinese space agency, like NASA or notThat, No high card Resolution Of Mars. And so onOrbit Able to provide very detailed maps of NASA’s MRO (and its Hiris camera) site, with a resolution of some ten centimetersDiligent landing Before its launch. The Tianwen-1 study is currently mapping the region to draw the most detailed maps. The goal is to find the most suitable place to land the rover safely in a flat environment where there are not too many large rocks and as much as possible.

An ambitious rover

At about 250 kilograms this rover is bigger than the rovers Spirit And Opportunity NASA is but a quarter of curiosity and perseverance. Equipped with six motorized wheels that allow it to move like a crab, the Jurong can travel up to 200 meters per hour. It has six instruments, including a laser cameraTool Chemcom American Rover Curiosity. In addition, there are optical cameras, a radar to examine the soil, a spectrometer, a magnetometer and a meteorological station (especially temperature, pressure and air gauges). Its four solar panels will generate the energy needed for its operation, which is expected to last more or less 90 days. If requested by China, the data could also be released from the Tianwen-1 orbit or the European Space Agency’s Mars Express probe.
