China blasts off on mission that could provide 1st samples of far side of the moon

In 2020, China became 1st country in nearly 5 decades to study samples from moon's more traversed side
China on Friday 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 centre 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.
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.
Hope to send crewed mission in 2030
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.
WATCH | China takes another step in ambitious moon plans:
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 co-operation between the U.S. and Chinese space programs without explicit congressional approval.
The latest mission carries scientific instruments from France, Italy and the European Space Agency in cooperation with Sweden. A small Pakistani satellite is also on board.
China's ambitious space program aims to put astronauts on the moon by 2030, as well as bring back samples from Mars around the same year and launch three lunar probe missions over the next four years. The next is scheduled for 2027.
Longer-term plans call for a permanent crewed base on the lunar surface, although those appear to remain in the conceptual phase.
China conducted its first crewed space mission in 2003, becoming the third country, after the former Soviet Union and the U.S., to put a person into space using its own resources.
The three-module Tiangong, much smaller than the ISS, was launched in 2021 and completed 18 months later. It can accommodate up to six astronauts at a time and is mainly dedicated to scientific research. The crew will also install space debris protection equipment, carry out payload experiments and beam science classes to students on Earth.
China has also said that it eventually plans to offer access to its space station to foreign astronauts and space tourists. With the ISS nearing the end of its useful life, China could eventually be the only country or corporation to maintain a crewed station in orbit.
The U.S. aims to put a crew back on the lunar surface by 2026 as part of a renewed commitment to crewed missions, aided by private sector players such as SpaceX and Blue Origin. They plan to land on the moon's south pole, where permanently shadowed craters are believed to be packed with frozen water.
