Jul 30, 2:14 PM NASA comments on uncontrolled reentry Latest Tracking and Impact Prediction (TIP) as of 17:25:00Z for CZ-5B (Long March 5B) (53240 / 2022-085B) shows projected re-entry at 16:51:00 (UTC) +/- 1 minutes at approximate latitude 3.4, longitude 113. The rocket will deliver the third and final lab module, Mengtian, to China's Tiangong Space Station. "We'll go through this again in October with Chang Zheng 5B Y4, which is scheduled to launch the next Chinese space station module." "Well, that's a wrap on the Chang Zheng 5B Y3 reentry," astronomer Jonathan McDowell said on Twitter Saturday. Jul 30, 5:18 PM Next Long March 5B rocket to launch in OctoberĪ second Long March 5B rocket is scheduled to be launched later this year, with experts preparing for another uncontrolled entry. The two previous launches of the Long March 5B rocket both had uncontrolled reentries, with rocket debris landing near the west coast of Africa in 2020 and in the Indian Ocean in 2021. And that's the big challenge with all this," he said. "If you're an hour off in predicting when that's going to happen, because it's going at 17,000 miles an hour, you're 17,000 miles off in where it's going to come down.

The exact point where the rocket booster would reenter the Earth's atmosphere couldn't be determined until within hours of reentry, experts said. The Chinese space station was started after the US barred Beijing from participating in the International Space Station.PHOTO: The rocket carrying China's second module for its Tiangong space station lifts off from Wenchang spaceport in southern China, on July 24, 2022. The Long March 5B rocket took off July 24 carrying one of the heaviest payloads in recent years, a module for China’s under-construction Tiangong space station. “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. SpaceX rocket boosters, for example, make vertical landings and are then captured, refurbished and reused in subsequent launches.Ĭhina has dismissed Western concerns over the debris, calling it a smear effort as the US-China space race escalates. 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.Įxperts have stressed that uncontrolled re-entries are avoidable. This is the third uncontrolled entry by a Chinese rocket booster in as many years. The Aerospace Corporation July 30, 2022 We are watching and for confirmation of #CZ5B reentry.
