Chinese spacecraft Chang’e-5 succeeds in recovering first lunar samples in 40 years | World news

Beijing : China’s Chang’e-5 probe successfully landed on Earth early on Thursday (December 17), bringing home the first samples of the moon for over 40 years.

According to China’s National Space Agency (CNSA), the spacecraft landed at 1:59 a.m. local time in Sizhi Wang Banner, an autonomous region of China’s Inner Mongolia

CNSA Director Zhang Kejian declared the success of the Chang’e-5 mission.

This has successfully completed China’s current three-stage orbital and landing exploration program and brought back samples that began in 2004, Xinhua News Agency reported.

It is China’s first attempt to recover material from aliens. The Chang’e-5 lunar probe was launched on November 24 at the foot of the Wenchang spacecraft.

It was the first attempt to take lunar samples over 40 years after the United States sent astronauts to the moon to collect samples. In the Soviet unmanned moon sampling mission, the spacecraft took off from the moon and returned directly to Earth.

The 8-ton Chang’e-5 spacecraft has four independent but interacting components. This includes one staying in lunar orbit with a docking station, one descending to the lunar surface and drilling a sample, one taking the material back to the dock station, and the other bringing the sample back to Earth.

The Chang’e-5’s return capsule was separated from orbit about 5,000 km above the Atlantic Ocean. The capsule entered the Earth’s atmosphere at an altitude of about 120 km. The parachute opened about 10 km above the ground.

The report said the capsule had landed smoothly in a predetermined area and that the search team recovered it.

The capsules will be airlifted to Beijing for opening, and moon samples will be delivered to the research team for analysis and research, CNSA said.

China will provide some samples to scientists from other countries, said Pei Zhaoyu, deputy director of CNSA’s Center for Lunar Exploration and Space Programs.

The Chang’e-5 is one of the most complex and challenging missions in Chinese aerospace history as it reached north of the Mons Rumker in Oceanus Procellarum.

On December 1st, a storm struck near the moon, the report said.

This place was chosen because it is younger in geological age than sampling areas in the United States and the USSR 40 years ago and has never been sampled. According to Chinese space scientists, about 2 kg of new samples are scientifically very valuable. Although samples of the moon have returned to missions in the United States and the Soviet Union, scientists need samples of more age groups to collect the full history of the moon.

 

Chang’e-5 broke through the lunar surface and caught matter on the surface in search of samples that document evolutionary events. Scientists could use modern analytical techniques to unravel the mystery of volcanic activity and meteorite impacts over the past billion years, the report said.

The probe collected material from multiple sites to ensure sample diversity. After the sample was sealed, the rover’s riser successfully took off from the moon and docked with the orbit-returner combination in the lunar orbit.

Samples were transferred to the returnee before being separated from the orbiter-returner. To avoid becoming space junk, the ascender made a controlled descent to the moon, CNSA said. Then the orbital-returner took home a valuable sample.

Pei said that the Chang’e-5 mission not only marks the end of China’s current lunar exploration program, but also laid the foundation for future manned lunar and deep space exploration.

This groundbreaking mission has some of the first achievements in China, including the first moon sampling, the first take-off from an alien, the first encounter and docking in the lunar orbit, and the first spacecraft to carry samples to re-enter Earth’s atmosphere at high speed. I took it. Said Fay.

 

China is planning to explore the moon in the future, including the construction of a basic version of the scientific research base, he said.
Pei said, “We hope to cooperate with other countries to build an international lunar science research base that can provide a shared platform for lunar scientific exploration and technology experiments.”

Meanwhile, China’s Mars probe, Tianwen-1, is now more than 100 million kilometers from Earth and is operating normally, CNSA said Tuesday (December 15).

CNSA said it will perform several orbital corrections and will slow down to enter Mars orbit in mid-February next year.

 

Except for India, the United States, Russia and the European Union have succeeded in sending missions to Mars, one of the most complex space missions to date.

India became the first Asian country to successfully launch the Mars orbiter Mangalyaan, which entered Mars orbit in 2014. India also became the first country to orbit Mars on its first attempt.

Xinhua News Agency On Thursday (December 17) in a comment on the lunar mission, some major countries are pushing ahead with a controversial agreement that allows signers or businesses to create an exclusive “safe zone” on the moon and to accelerate it. He said it was regrettable that he was adopting the strategy for this. The militarization of space.

The comment added that these self-trading efforts to pursue cosmic hegemony should be flatly rejected.
