At a major milestone, China succeeded in landing a congratulatory rover on Mars

China’s Jurong Mars rover, mounted on a rocket-powered lander, left the orbiting Tianwen-1 mothership on Friday and descended to land on the red planet, official news outlets confirm. did. ..

The China National Space Administration, named after the Chinese mythological god of fire, landed on a vast plain known as the Utopia Planitia at 7:18 pm on Friday (7:18 am on Saturday Eastern Standard Time). I confirmed that I did. The atmosphere of Mars.

Thomas Zurbuchen, NASA’s Director of Space Sciences at NASA Headquarters, congratulated China on the successful landing. Tweet“We look forward to this mission, together with the world’s scientific community, making an important contribution to the understanding of humanity’s red planet.”

Like the earlier NASA Perseverance Rover, Congratulations relied on heat shields and protective aeroshells to protect it from the extreme temperatures that occur after hitting the atmosphere near 3 miles per second. .. After passing through the plasma heating zone, a large parachute was probably deployed as planned, dramatically decelerating the aircraft to subsonic speeds.

Finally, about seven minutes after the collision with the atmosphere, the lander was programmed to fall from the parachute, launching a small rocket engine and powering it down to the surface.

After extensive testing and checkout (China has not revealed the rover’s schedule), two ramps unfold, a six-wheeled rover rolls off the lander’s upper deck, and robot exploration for at least three months. You can get down to the surface for.

“Tianwen-1 will put all the rover in orbit, land and release it in the first attempt,” the mission manager wrote in the journal Nature Astronomy before launch. “No planetary missions have been carried out this way. If successful, that would mean significant technological progress.”

Tianwen-1 Orbiter and Congratulatory Lander Arrived in orbit around Mars February 10th, seven months after the launch from the Wenchang Spacecraft Launch Site on Hainan Island in the South China Sea. Eight days later, NASA’s $ 2.4 billion Perseverance Rover Successful landing At the Jezero Crater on the edge of the Utopia Plain.

Nuclear patience is NASA’s ninth and most technologically advanced Mars lander, a series of sophisticated cameras, spectrometers, and others designed to look for signs of microbial life in the past. The equipment is installed.

We have also deployed a small helicopter, Ingenuity, which has successfully completed five test flights so far, equipped with a complex sample cache mechanism for collecting rock and soil samples to eventually return to Earth.

Tianwen-1 is the first all-China mission to the Red Planet and the most sophisticated interplanetary probe to date. Not in the same league as Perseverance, but the combination of a powerful orbiter and surface rover for China’s first attempt on Mars is a precursor to a more ambitious mission to come.

Only two countries, the United States and the Soviet Union, have landed spacecraft on Mars. The NASA record shows that 9 landings were successful in 10 trials, while Russia survived 8 landing failures and was only a partial success.

“Mars certainly has life! We are the life of the party!” The Chinese space agency tweeted.

The Tianwen-1 mothership has been orbiting the poles of Mars for two years and is equipped with seven devices, including high- and medium-resolution cameras. Ground penetrating radar; Minerals spectrometer; Magnetometer; and two charged particle detectors.

Approximately the same size as NASA’s Spirit and Opportunity Rover, which landed on Mars in 2004, the 530-pound rover is equipped with six devices, including a multispectral camera, terrain camera, ground penetrating radar, magnetic field detector, and meteorology. I am. Sensor etc.

Like Perseverance, Chinese flight controllers cannot operate Zhurong Rover in real time. Mars and Earth are now 198 million miles apart, and a radio signal traveling at 186,000 miles per second takes nearly 18 minutes to cross the bay.

Instead, the flight controller uplinks the rover’s command, waits for the result, and relays it to Earth via the Tianwen-1 orbiter.

China has successfully sent two rover to the moon, including one that has landed on the other side, which it has never visited. Attempts to send an orbiter to Mars on a Russian rocket in 2011 failed when Zenit’s booster broke down.
