Your support makes all the difference.China has finally broken its silence over the mysterious disappearance of its Mars rover, Zhurong.
The equipment has been struck in hibernation for almost a year, after disappearing in May 2022. It has probably been covered by an excessive accumulation of sand and dust, its mission designer said.
The statement breaks a long-standing silence over the fate of the mission. China tends to conduct its work in space with more secrecy than other countries’ space agencies, suchas Nasa.
The motorised rover Zhurong, named after a mythical Chinese god of fire, was expected to have woken up in December after entering a planned sleep mode in May 2022 as falling solar radiation with the advent of winter cut its power generation.
“We have not had any communication from the rover since it entered hibernation,” said Zhang Rongqiao, chief designer of China‘s Mars exploration programme. “We are monitoring it every day and believe it has not woken up because the sunlight has not yet reached the minimum level for power generation.”
An unforeseen pile-up of dust most likely affected power generation and Zhurong’s ability to wake up, Chinese state television reported on Tuesday, quoting Zhang.
A camera on board a NASA probe orbiting Mars showed the Chinese rover had not moved since at least September, according to official images.
The 240-kg (530-pound) Zhurong, which has six scientific instruments including a high-resolution topography camera, was tasked with studying the planet’s surface soil and atmosphere after landing with no mishap in May 2021.
Powered by solar energy, Zhurong also looked for signs of ancient life, including any subsurface water and ice, using a ground-penetrating radar.
The rover had explored the Martian surface for 358 days and travelled for 1,921 metres (2,100 yards), Zhang said, far exceeding its original mission time-span of three months.
Aside from Zhurong, two other robotic rovers have been operating on Mars - NASA’s Perseverance and Curiosity, with the former roaming the planet’s surface for more than two years and the latter for over a decade.
