China sends a probe to get samples from the less-explored far side of the moon

A Long March-5 rocket, carrying the Chang’e-6 spacecraft, blasts off from its launchpad at the Wenchang Space Launch Site in Wenchang, south China’s Hainan Province, last week

China last week launched a lunar probe to land on the far side of the moon and return with samples that could provide insights into differences between the less-explored region and the better-known near side.

It is the latest advance in China’s increasingly sophisticated space exploration program, which is now competing with the U.S., still the leader in space.

China also has a three-member crew on its own orbiting space station and aims to put astronauts on the moon by 2030. Three Chinese lunar probe missions are planned over the next four years.

Free from exposure to Earth and other interference, the moon’s somewhat mysterious far side is ideal for radio astronomy and other scientific work. Because the far side never faces Earth, a relay satellite is needed to maintain communications.

The rocket carrying the Chang’e-6 lunar probe — named after the Chinese mythical moon goddess — lifted off Friday at 5:27 p.m. as planned from the Wenchang launch center on the island province of Hainan. About 35 minutes later it separated entirely from the massive Long March-5 rocket — China’s largest — that had slung it into space, as technicians monitoring the launch from ground control smiled and applauded.

Shortly afterward, launch mission commander Zhang Zuosheng took to a podium at the front of the room and said the launch had gone off exactly as planned and the spacecraft was on its set trajectory. “I declare this launch mission a complete success,” Zhang said to further applause.

The Philippine Space Agency issued a statement saying expected debris from the rocket launch was “projected to have fallen within the identified drop zones.”

China in 2021 was forced to defend its handling of a rocket booster that burned up over the Indian Ocean after the administrator of the American space agency and others accused Beijing of acting recklessly by allowing its rocket to fall to Earth seemingly uncontrolled after the mission.

Huge numbers of people crowded Hainan’s beaches to view the launch, which comes in the middle of China’s five-day May Day holiday. As with previous recent launches, the event was televised live by state broadcaster CCTV.

After orbiting the moon to reduce speed, the lander will separate from the spacecraft and within 48 hours of setting down it will begin drilling into the lunar surface and scooping up samples with its robotic arm. With the samples sealed in a container, it will then reconnect with the returner for the trip back to Earth. The entire mission is set to last 53 days.

China in 2020 returned samples from the moon’s near side, the first time anyone had done so since the former Soviet Union in 1976. Analysis of the samples found they contained water in tiny beads embedded in lunar dirt.

Also in the past week, three Chinese astronauts returned home from a six-month mission on the country’s orbiting space station after the arrival of its replacement crew.

China built its own space station after being excluded from the International Space Station, largely because of U.S. concerns over the Chinese military’s total control of the space program amid a sharpening competition in technology between the two geopolitical rivals. U.S. law bars almost all cooperation between the U.S. and Chinese space programs without explicit congressional approval. CHRISTOPHER BODEEN, TAIPEI, MDT/AP
