Debris from an uncontrolled Chinese rocket is expected to come crashing into Earth this weekend. Here’s everything you need to know.
All about the Chinese rocket and its uncontrolled re-entry
Scientists are expecting debris from a Chinese rocket to crash into Earth this weekend. The probability of it landing in a populated area is low. However, it is raising questions about how various nations take responsibility for their space junk. Previously NASA has called for the Chinese space agency to develop their rockets to disintegrate into smaller pieces upon re-entry. However, recent rockets heading to Tiangong, China’s unfinished space station lack the ability of controlled re-entry.
One of the most recent Chinese rocket launches to Tiangong was a Long March 5 rocket carrying a lab module. The government on Wednesday stated their rocket’s reentry poses little risk for those on the ground. This is because they are expecting it to land in the sea. However, there is a chance for some space junk to come down over the populated area. The recent event in May 2020 damaged properties on Ivory Coast. The empty body of the rocket is in an elliptical orbit around the Earth. Here, it is being dragged towards an unruly re-entry. According to The Aerospace Corporation, a California-based non-profit organization, the event will occur at around 00:24 GMT on Sunday.
More on the re-entry and space junk
Unfortunately, it is too early to know the exact location where the 25-tonne of debris will land. The currently known area spans the US, Brazil, Australia, Southeast Asia, and India. “Regarding the Long March 5 launched several days ago, there is no known (re-entry) plan, which equally has been the case for previous launches of this vehicle,” stated Sean Goldsbrough. Goldsbrough is a UK-based space-tracking expert and the director of Northern Space and Security (NORSS). “The lack of communication, coupled with what could be considered unpredictable results for the previous two launches, is primarily what causes concern,” he added.
The Chinese have launched the Long March 5 rocket configuration twice before to the Tiangong station. On both occasions, space junk from the core stage of the rocket landed on Ivory Coast and the Indian Ocean. While the incidents did not cause injury, they garnered a lot of criticism.
“It is clear that China is failing to meet responsible standards regarding their space debris. Spacefaring nations must minimize the risks to people and property on Earth of re-entries of space objects and maximize transparency regarding those operations,” stated Bill Nelson. Nelson is the administrator of NASA.
