China Pushes for Primacy in Space

In a first for any country, the Chang'e-4 probe is set to touch down on the "dark side" of the moon on or around Jan. 3, according to state media, and dispatch a rover in a vast crater to explore the moon's interior. While impressive in itself, the mission is a step toward bolder objectives: China plans to operate a manned lunar base by 2030 and lead the world into a new age of space exploration.
For its part, the U.S. is reviving its manned space program after letting it languish in favor of unmanned exploration...
Already rivals on Earth, the U.S. and China are now the main contenders in a race to determine "who will be in a position to obtain the vast resources in space, secure the routes of trade and write the rules of space commerce," said Namrata Goswami, an expert on China's space program at Auburn University Futures Lab in Alabama.
China, she added, "is best placed to win," thanks to a methodical program that has mapped out clearly defined objectives decades into the future...
A late entrant to the space race, China conducted its first manned space flight in 2003, 42 years after the Soviet Union and the U.S. first achieved the feat.
Since then, Chinese leaders have portrayed the conquest of space as an essential marker in the nation's rise and backed that ambition with ready financing. China National Space Administration is the world's best-funded space agency after NASA, and its development of military capabilities such as antisatellite weapons and its busy schedule of missions have jolted the U.S.
While space matters again to American policy makers, the U.S. effort has lost its focus, having been underfunded since the Reagan era, according to Mr. Cheng,an expert on China's space capabilities.The U.S. has had to rely on other countries to send American astronauts into space since the end of the Space Shuttle program in 2011. Timetables to put astronauts on the moon by 2023 and on Mars by 2033 look difficult to achieve, some analysts said, and could easily fall victim to shifting political priorities.
...Chinese spending has been better targeted over a long period, with clear goals, achievable timelines and unwavering top-level backing, the analysts said. The U.S., by contrast, earlier funded a program to return astronauts to the moon and then canceled it in 2010.
"China sets long-term goals and meets them," said Auburn's Ms. Goswami. "They see the moon as a vast energy resource for sustainable development. Their plan is to industrialize the moon."
In 2018, China sent more rockets into orbit than any other country for the first time: 36, compared with the U.S.'s 30. Beyond the current moon mission, China is scheduled to deploy a space station by 2022 and set up mankind's first permanent lunar base eight years later.
The Beidou satellite navigation system, comprising 35 location satellites, is due to go fully online in 2020, becoming a genuine rival to the U.S. Global Positioning System, which currently has 31 operational satellites.
President Xi Jinping, in a nationally broadcast call to Chinese astronauts aboard the country's first orbital space lab in 2013, portrayed space exploration as "part of the dream to make China stronger."
Since then, senior officials at China's space agency have likened the race for space to China's tussle to claim disputed islands in the East and South China Seas.
"The universe is like the ocean: the moon is like the Diaoyu Islands and Mars is like Scarborough Shoal," Ye Peijian, head of China's moon missions, said in a 2017 interview with state TV, using China's names for contested territories in the South China Sea. "We will be blamed by our descendants if we don't go there…and others get there before us."
An early harvest of China's long-range planning should be evident in coming weeks with the lunar mission. Operating on the moon's far side is a feat in itself since direct communications with Earth aren't possible. In June, China placed a relay satellite 50,000 miles beyond the moon to enable communication with the lunar rover.
The rover will comb the lunar surface's far side, scraping up samples. In a year's time, another mission, Chang'e-5, will retrieve samples and return them to Earth.
Some Chinese scientists see the moon's abundant supplies of helium-3, a nonradioactive isotope, as a potential source of nuclear-fusion energy.
By its timetable, the Chinese space agency will have a fully operational space station in orbit in 2022...

 The mission aims for a world first: to land on and study the far side of the moon (pictured). The 20 manned and unmanned lunar landings that have predated it (11 American, eight Soviet and one Chinese) all explored more accessible regions of the moon's surface that are visible from Earth.

A spacecraft on the far side of the moon cannot communicate directly with the Earth. To solve this problem, China in June positioned a relay satellite called Magpie Bridge roughly 50,000 miles beyond the moon, where it will bounce transmissions between the Chang'e-4 and ground stations.

The Chang'e-4 blasted off from the Xichang Satellite Launch Center in southwest China on Dec. 8, loaded onto a Long March 3B rocket. The craft completed the 238,855-mile journey to the moon in roughly 4½ days. Flight controllers have been running tests and refining the Chang'e-4's orbit, before deploying the lander in early January.

The Chang'e-4's target is the Von Karman Crater, a lunar impact crater roughly 115 miles across and 8 miles deep. By exploring the crater's surface, the mission aims to gain insights into the moon's internal composition.

After touchdown the Chang'e-4 lander, which weighs around 2,400 pounds, will deploy the 300-pound rover to start exploring the Von Karman Crater. The lander and rover carry instruments including cameras, radar and a system for studying the lunar wind. An onboard experiment will also test the ability of seeds and silkworm eggs, stored within a climate-controlled biosphere, to survive on the moon. The six-wheel rover is expected to function for three months.
