Still, the ocean remains the safest bet for where the debris will land, he said, just because it takes up most of the Earth’s surface. And so if you’re an hour out at guessing when it comes down, you’re 18,000 miles out in saying where.” “The thing is traveling at like 18,000 miles an hour. And in that two-day period, it goes around the world 30 times,” McDowell said. “We expect it to reenter sometime between the eighth and 10th of May. That enormous range is, in part, a result of the rocket’s blistering speed – even slight changes in circumstance can drastically change its trajectory. The European Space Agency has predicted a “risk zone” that encompasses “any portion of Earth’s surface between about 41.5N and 41.5S latitude” – which includes virtually all of the Americas south of New York, all of Africa and Australia, parts of Asia south of Japan and Europe’s Spain, Portugal, Italy and Greece.Ĭhinese rocket debris is expected to crash into Earth soon. And so I would not lose one second of sleep over this on a personal threat basis,” Jonathan McDowell, an astrophysicist at the Astrophysics Center at Harvard University, told CNN this week. “The risk that there will be some damage or that it would hit someone is pretty small – not negligible, it could happen – but the risk that it will hit you is incredibly tiny. The good news is that debris plunging toward Earth – while unnerving – generally poses very little threat to personal safety. The rocket’s “exact entry point into the Earth’s atmosphere” can’t be pinpointed until within hours of reentry, Howard said, but the 18th Space Control Squadron is providing daily updates on the rocket’s location through the Space Track website.
The Long March 5B rocket, which is around 100 feet tall and weighs 22 tons, is expected to enter Earth’s atmosphere “around May 8,” according to a statement from Defense Department spokesperson Mike Howard, who said the US Space Command is tracking the rocket’s trajectory. A large Chinese rocket that is out of control is set to reenter Earth’s atmosphere this weekend, bringing a final wave of concern before its debris makes impact somewhere on Earth. "There's not really much to argue with there."įollow Brett on Twitter at. "I mean, really what Aerospace's point here is just to report on what's going on - make sure that people you know are informed they understand they have a realistic view of what the situation is," Sorge added. Muelhaupt said that he is not aware of "any direct comment about Aerospace by the Chinese," although he has "seen general commentary about the West hyping this unnecessarily." Sorge said that the Chinese government "made some comments in the press at one point, but mostly not." "So There isn't really a direct legal way to control what's going on on an international level."įor their part, neither China's national space agencies nor any other official government body has issued a response to The Aerospace Corporation's regular tracking of and communications about falling Long March 5B rocket bodies. "And the reality is there aren't any real laws, treaties, internationally that govern what you're allowed to do in terms of reentry," Sorge said. Marlon Sorge, Executive Director for The Aerospace Corporation's Center for Orbital and Reentry Debris Studies ( CORDS), said during today's briefing that international laws are unclear when it comes to these types of reentries. See China's huge uncontrolled rocket debris fall from space in fiery skywatcher videosĪs more of these uncontrolled Chinese reentries occur, more and more voices are calling for the establishment of international laws or norms to prevent such incidents from happening. 25-ton Chinese rocket debris crashes to Earth over Indian Ocean China launches final module to complete Tiangong space station (video) But the Long March 5B core stage reaches orbit, and China lets it stay up until drag brings it down in an uncontrolled fashion.) (Most rockets are designed such that their core stages ditch into the ocean or over unoccupied land shortly after liftoff, or come back to Earth for safe landings, in the case of SpaceX vehicles. And in 2020, after the rocket's debut launch, pieces of the vehicle's core stage reportedly hit the ground in Ivory Coast. Another Long March 5B fell into the Indian Ocean in April 2021 after China's space agency did not perform a controlled deorbit. In July, between 5.5 tons to 9.9 tons (5 to 9 metric tons) of another Long March 5B crashed into the Indian Ocean after surviving the fall through Earth's atmosphere. This is far from the first of such incidents. (Image credit: The Aerospace Corporation) Areas not under the lines are not exposed to the debris. Possible reentry locations lie anywhere along the blue and yellow ground tracks. A visualization of the possible tracks the falling Long March 5B rocket body could take.
