Video and audio clips tell about the mission to Mars


China released several video clips captured by the country’s Tianwen March 1 mission to the public on Sunday, including one with an audio recording that is the first to come out of the historic interplanetary expedition.

The clips, released by the National Space Administration of China, recorded the processes of the landing on Mars by the Tianwen 1 landing capsule, the departure of the Zhurong rover from the capsule and its movement across the planet’s soil. red. They also provide the first opportunity for people around the world to see a moving rover on the surface of Mars.

The ambient sound during Zhurong’s rolling process on the Martian surface has also been recorded and released, allowing people to hear the first sounds transmitted by the Chinese robot, which is now about 360 million kilometers from Earth.

The administration also released two photos taken by Zhurong that show the surroundings and the tracks left by his wheels.

Pang Zhihao, a retired space flight researcher at the Chinese Academy of Space Technology, said the sounds of Mars have considerable scientific value.

“Through their analyzes, scientists will be able to study environmental factors on Mars at this time, such as weather and wind speed, thus advancing their understanding of the planet,” he said, adding that all Previous sounds of Mars had been recorded by Landers and rovers from the United States.

“Returning videos and photos to Earth is never an easy task as it challenges the technology and capabilities of a mission to Mars,” Pang said.

Sunday morning, Zhurong, named after the Chinese god of fire in ancient mythology, had operated 43 days on Mars and traveled 236 meters to survey the barren planet. Meanwhile, the mission’s orbiter continued to travel around the Red Planet for orbital exploration, according to an administration statement.

With an expected lifespan of three months, the 240-kilogram Zhurong is responsible for studying landforms, geological structures, soil characteristics, potential locations of water and ice, and atmospheric characteristics. and environmental, as well as magnetic and gravitational fields and other physical properties.

The 1.85-meter-tall rover is the centerpiece of the Tianwen 1 mission, the country’s first interplanetary adventure, and is also the sixth rover on the Red Planet, after five from the United States.

The rover’s six wheels, powered by four solar panels, allow it to move at a maximum speed of 200 meters per hour on the Martian surface. But the robot will not travel as fast, as it has to detect and avoid obstacles along the route and will stop for scientific operations.

Tianwen 1, named after an ancient Chinese poem, was launched on July 23 by a heavy Long March 5 carrier rocket from the Wenchang Space Launch Center in Hainan Province, starting the country’s first mission to another planet. .

The spacecraft traveled more than 470 million km and performed several trajectory maneuvers before entering orbit of Mars on February 10. Zhurong landed on Mars on May 15.
