More dead than alive: Chinese rover has been motionless for six months

What's going on with China's Zhurong rover?In May 2022, he fell into a planned "hibernation" on the Utopia Plain - a large plain that is located in the northern hemisphere of Mars. However, in December he had to wake up and continue his work. During this period, winter in the northern hemisphere ends, and sunlight becomes sufficient to power the apparatus. However, now there is enough reason to believe that the rover has not woken up, since its service life on Mars has ended. The Chinese space agency has not yet said anything at all about this, but the pictures taken by the Mars Reconnaissance Orbiter have brought clarity to the situation.

China's Zhuzhong rover never came out of hibernation

China's Zhurong rover crashed?

Zhurong is China's first rover.We previously reported that it successfully landed on the Martian Utopia plain on May 15, 2021. This vast plain has a diameter of over 3,000 kilometers. It was formed at the dawn of the formation of Mars as a result of the impact of a powerful meteorite.

Zhurong's six-wheeled vehicle, reminiscent ofAmerican rovers of the 2000s "Spirit" and "Opportunity", the apparatus weighs 240 kg. Like its American counterparts, it is equipped with cameras that take pictures of the planet and are part of the navigation system. It also has on board five separate instruments designed to study the mineral composition of rocks and weather on the surface of the Red Planet.

To determine the chemical composition of the roveruses a powerful laser capable of burning rocks. At the same time, its main difference from American counterparts is the presence of a scanner, or ground penetrating radar, capable of detecting water or ice under the ground surface.

NASA photos show the Chinese rover has been stationary since September 2022. In the photo, it is visible as a blue dot (top left in the first photo, and bottom right in the other two pictures).

Zhurong had high hopes in terms ofsearching for traces of life. According to some assumptions, in the place where he landed, there was once an ocean with living organisms living in it. But, apparently, he was not destined to find traces of life. NASA images released on February 21 show that the rover is stationary from September last year to February this year. That is, the device could not wake up in December, as it was planned.

In addition, in January there was information fromanonymous sources allegedly related to the Tianwen-1 mission. The message said that the mission control center did not receive feedback from the apparatus, as reported by the South China Morning Post.

At the end of December 2022, NASA's InSight rover also stopped communicating.

Why did the Chinese rover break down?

According to some experts, the reasonThe robot's malfunction may lie in the abnormally cold Martian winter. For Zhurong to operate, temperatures must be at least -15 degrees, according to officials in charge of the Tianwen-1 mission.

It is also possible that solar panelsThe device is covered with dust, as a result of which it simply does not have enough energy to start. Similar cases on Mars have already occurred - due to dusty solar panels, NASA's InSight rover died. He spent four years on the Red Planet, and last contacted at the end of December 2022.

But it's too early to bury Zhuzhong.He has not yet been officially declared dead. If the reason for his “hibernation” is the low temperature, then he can still wake up when it gets warmer on Mars. Even if the dusty panels are the cause, theoretically the apparatus can come to life, but for this a powerful storm must blow the dust off its panels.

However, even if the rover neverwakes up, in terms of the duration of the work, he coped with his task. Initially, it was assumed that the device will work only 90 Martian days. But Zhuzhong worked throughout the year, that is, until May 2022. At present, the Tianwen-1 orbiter continues to operate in the orbit of Mars. It collects data on the surface of the planet and its atmosphere, and will work regardless of the future fate of the apparatus.

Finally, we recall that China plans to overtakeUnited States and deliver Martian soil to Earth in 2031, that is, two years earlier. But the Tianwen-2 mission will be launched first, in which Chinese scientists plan to study the Kamoaleva asteroid, which is a quasi-satellite of the Earth.
