China wants to build a power station in space
Unhappy with the US’s dominance in space, and with an $8bn annual budget, China plans to space’s first solar power station
Beijing — China’s space ambitions are shifting into a higher orbit.
Following its successful and world-beating trip to the far side of the moon, China is preparing to build a solar power station in space, as the world’s number two economy strives to burnish its superpower credentials. With an $8bn annual budget for its space programme, second only to the US, China is seeking to compete with its rival for economic, military and technological dominance.
Scientists have already started construction of an experimental base in the western Chinese city Chongqing. Initially, they plan to develop a smaller power station in the stratosphere between 2021 and 2025, a 1MW-level solar facility in space by 2030, and eventually larger generators, according to the state-backed Science and Technology Daily.
Here’s what China’s been doing in space:
The nation’s space scientists successfully landed a lunar probe on the far side of the moon on January 3, capping a series of missions and giving a boost to China’s ambitions. Landing on the unexplored region will enable Chang’e-4, the rover named after the mythical Moon Goddess, to better study the moon because of the lack of electromagnetic interference from Earth. The vehicle is equipped with a low-frequency radio spectrometer to help scientists understand “how the earliest stars were ignited and how our cosmos emerged from darkness after the Big Bang,” according to China’s official Xinhua News Agency.
Reminiscent of the 2015 science fiction film The Martian starring Matt Damon, China’s lunar mission is also testing if the barren moon can support life. Pictures sent back from Chang’e-4 last month showed the first green leaf from cotton seeds nine days after the experiment was initiated, according to Chongqing University, which led the biological project. The test load on the mission carried cotton, canola, potato, yeast and fruit fly.
China has more such missions in the pipeline. Four more versions of the Chang’e-4 probe are in the offing, with at least two of them planned for a landing on the moon’s south pole, according to Wu Yanhua, vice-administrator of the China National Space Administration. The agency will also explore setting up a research base on the moon. A Mars probe is likely by the end of this decade.
China aims to build its own space station about 2022. Dubbed Tiangong, or Heavenly Palace, it will have a core module and two other modules for experiments, altogether weighing 66 tonnes and able to carry three people, with a designed lifecycle of at least 10 years. The facility would be used for scientific research in a dozen areas including biology, physics and material sciences.
President Xi Jinping has loosened the government’s monopoly on space launches, fueling the formation of small domestic companies with dreams of challenging companies such as Elon Musk’s SpaceX, Jeff Bezos’s Blue Origin and Richard Branson’s Virgin Galactic. The start-ups are receiving funding from China-based venture capitalists and private equity investors and can also rely on the expertise of rocket scientists from China’s space programme.
Taking its rivalry with the US to the heavens, China is spending at least $9bn to build a navigation system and cut its dependence on the American-owned GPS — whose satellites beam location data used by smartphones, car navigation systems, the microchip in your dog’s neck and guided missiles. And, all those satellites are controlled by the US Air Force, making the Chinese government uncomfortable. So, it has developed an alternative called the BeiDou Navigation System, which will eventually provide positioning accuracies of 1m or less with use of a ground support system.
The Asian power is developing sophisticated space capabilities such as “satellite inspection and repair” and clearing up orbiting junk — “at least some of which could also function” as weapons against US satellites, the US Defence Intelligence Agency said this month. China’s foreign ministry has said the US allegations were “groundless”.
