![]() ![]() The treaty has only been invoked once before ( for the Cosmos 954 incident) and therefore may not be regarded as a powerful disincentive. In the case of the Long March 5B, this would impose potential liability on China. The 1972 Liability Convention, a UN treaty, imposes liability on “launching states” for damage caused by their space objects, which includes an absolute liability regime when they crash to Earth as debris. International law sets out a compensation regime that would apply in many circumstances of damage on Earth, as well as when satellites collide in space. As we send more objects into space, the chances of a calamitous crash-landing will only increase. In 2007, pieces of debris from a Russian satellite narrowly missed a Chilean passenger planeflying between Santiago and Auckland. It was just a quirk of fate that Cosmos 954 did not land on Toronto or Quebec City, where the radioactive fallout would have necessitated a large-scale evacuation. But for anyone falling foul of the extremely long odds, the consequences would be truly disastrous. Of course, more than 70% of Earth is covered by oceans, and only a minuscule fraction of the remaining 30% is covered by your house. Since the late 1970s, pieces of space debris have fallen to Earth regularly and are viewed with increasing concern. Canada billed the Soviet Union more than C$6 million, having spent millions more, but was ultimately paid only C$3 million. The clean-up operation took months but located only a portion of the debris. With the Cold War at its height, the sensitivity of the nuclear technology onboard Cosmos 954 led to an unfortunate delay in locating and cleaning up the wreckage, because of the distrust between the Soviet Union and the Canadian/US recovery effort. Just one year before SkyLab’s demise, a Soviet remote sensing (spy) satellite, Cosmos 954, plummeted into a barren region of Canada’s Northwest Territories, spreading radioactive debris over several hundred square kilometres. More debris may fall to Earth later this year, when China will be launching another Long March rocket to the space station, McDowell said.Also read: China begins building three person space station, first launch to take place soonĪlthough there have been no recorded deaths or serious injuries from people being hit by space debris, that’s no reason to think it’s not dangerous. “The Chinese are right that the best bet is that it will fall in the ocean,” he said, although “there are plenty of populated areas” within the rocket booster’s range. That booster is now “dead” and beyond the control of the Chinese space agency, said Jonathan McDowell, an astrophysicist at the Center for Astrophysics, which is operated by Harvard University and the Smithsonian Institution. “It is critical that China and all space faring nations and commercial entities act responsibly and transparently in space to ensure the safety, stability, security, and long-term sustainability of outer space activities.”Īlso read: Can space junk actually kill you? Scientists explainĬhina’s most recent launch, which sent a module to the nation’s space station, included a booster to put the spacecraft into orbit. “It is clear that China is failing to meet responsible standards regarding their space debris,” NASA Administrator Bill Nelson said that month. In May 2021, pieces of another Long March rocket landed in the Indian Ocean, prompting concern that the Chinese space agency had lost control of it. “Due to the uncontrolled nature of its descent, there is a non-zero probability of the surviving debris landing in a populated area - over 88% of the world’s population lives under the reentry’s potential debris footprint,” Aerospace said Tuesday. The descent of the booster, which weighs 23 metric tons (25.4 tons), would be part of what critics say is a series of uncontrolled crashes that highlights the risks of China’s escalating space race with the US. “The US and Western media deliberately exaggerate and exaggerate the ‘loss-of-control’ of the Chinese rocket debris and the probability of personal injury caused by the rocket debris, obviously with bad intentions,” Shanghai-based news site Guancha.cn said Tuesday. “The US is running out of ways to stop China’s development in the aerospace sector, so smears and defamation became the only things left for it,” the Global Times newspaper reported, citing Song Zhongping, a television commentator who closely follows China’s space program. The possible debris field includes much of the US, as well as Africa, Australia, Brazil, India and Southeast Asia, according to Aerospace’s predictions.Īlso read: Indian-origin prof is 1st Canadian to win global award for pathbreaking researchĬoncern over the reentry and the impact it could have is being dismissed by China, however, with state-backed media saying the warnings are just “sour grapes” from people resentful of the country’s development as a space power.
