BEIJING — China’s space agency says a core segment of its rocket has re-entered Earth’s atmosphere over the Indian Ocean near the Maldive Islands early Sunday.
Officials say the upper stage of its Long March 5B rocket that launched the core module of its space station will mostly burn up on re-entry, posing little threat to people and property on the ground.
Th agency didn’t say if any debris had fallen on any of the 1,192 islands that make up the Maldives.

The 23-ton (21 metric tons) core stage likely will fall into an uninhabited area, given that 70% of Earth’s surface is covered by ocean, according to space.com. Entities around the world are keeping an eye out just in case — and providing regular updates online.
As of Saturday evening, the falling rocket booster was forecast to reenter Earth’s atmosphere over the Pacific Ocean about 8:30 p.m. PDT (0330 GMT), according to a Twitter update from Aerospace Corp., which is tracking the object.
Foreign Ministry spokesperson Wang Wenbing said Chinese authorities will release information about the re-entry of the rocket, expected over the weekend, in a “timely manner.”
Wang said China “pays great attention to the re-entry of the upper stage of the rocket into the atmosphere.”
“As far as I understand, this type of rocket adopts a special technical design, and the vast majority of the devices will be burnt up and destructed during the re-entry process, which has a very low probability of causing harm to aviation activities and the ground,” Wang said at a regularly scheduled briefing.
Usually, discarded rocket stages re-enter the atmosphere soon after liftoff, normally over water, and don’t go into orbit.
Earlier, China’s space agency had not said whether the main stage of the rocket is being controlled or will make an out-of-control descent. Last May, another Chinese rocket fell uncontrolled into the Atlantic Ocean off West Africa.
The Communist Party newspaper Global Times said the stage’s “thin-skinned” aluminum-alloy exterior will easily burn up in the atmosphere, posing an extremely remote risk to people.
Where won’t be known until shortly before re-entry
Where it will hit “cannot be pinpointed until within hours of its reentry,” the Pentagon said in a statement Tuesday.
White House press secretary Jen Psaki said at a Wednesday briefing that the U.S. Space Command was “aware of and tracking the location” of the Chinese rocket.
The nonprofit Aerospace Corp. expects the debris to hit the Pacific near the Equator after passing over eastern U.S. cities. Its orbit covers a swath of the planet from New Zealand to Newfoundland.
The Long March 5B rocket carried the main module of Tianhe, or Heavenly Harmony, into orbit on April 29. China plans 10 more launches to carry additional parts of the space station into orbit.
The roughly 30-meter (100-foot) -long stage would be among the biggest space debris to fall to Earth.
The 18-ton rocket that fell last May was the heaviest debris to fall uncontrolled since the former Soviet space station Salyut 7 in 1991.
China’s first space station, Tiangong-1, crashed into the Pacific Ocean in 2016 after Beijing confirmed it had lost control. In 2019, the space agency controlled the demolition of its second station, Tiangong-2, in the atmosphere.
In March, debris from a Falcon 9 rocket launched by U.S. aeronautics company SpaceX fell to Earth in Washington and on the Oregon coast.
