Chinese rocket is expected to plunge back to earth late Saturday or early Sunday, impact location unknown

Remnants of China’s largest rocket launched last week are expected to plunge back through the atmosphere late Saturday or early Sunday, European and U.S. tracking centres said on Saturday.

China’s foreign ministry said on Friday that most debris from the rocket will burn on re-entry and is highly unlikely to cause any harm, after the U.S. military said that what it called an uncontrolled re-entry was being tracked by U.S. Space Command.

EU Space Surveillance and Tracking (EU SST) said its latest prediction for the timing of the re-entry of the Long March 5B rocket body was 190 minutes either side of 0211 GMT on Sunday.

The Center for Orbital Reentry and Debris Studies (CORDS) at Aerospace Corporation, a U.S. federally funded space-focused research and development centre, updated its prediction for re-entry to four hours on either side of 0330 GMT on Sunday.

EU SST said on its website that the statistical probability of a ground impact in populated areas is «low», but noted that the uncontrolled nature of the object made any predictions uncertain.

The Long March 5B – comprising one core stage and four boosters – lifted off from China’s Hainan island on April 29 with the unmanned Tianhe module, which contains what will become living quarters on a permanent Chinese space station. The rocket is set to be followed by 10 more missions to complete the station.

Long March 5 rockets have been integral to China’s near-term space ambitions – from the delivery of modules and crew of its planned space station to launches of exploratory probes to the Moon and even Mars.

The Long March launched last week was the second deployment of the 5B variant since its maiden flight in May last year.

Harvard-based astrophysicist Jonathan McDowell previously told Reuters there is a chance that pieces of the rocket could come down over land, perhaps in a populated area, as in May 2020, when pieces from the first Long March 5B rained down on the Ivory Coast, damaging several buildings, though no injuries were reported.
