China's defunct Tiangong-1 space lab mostly broke up on re-entering the Earth's atmosphere above the South Pacific, the BBC reported today quoting Chinese and US reports.
It had re-entered the atmosphere around 00:15 GMT on Monday, China's Manned Space Engineering Office said.
Tiangong-1 was launched in 2011 to carry out docking and orbit experiments.
It was part of China's efforts to build a manned space station by 2022, but stopped working in March 2016.
The rather vague "above the South Pacific" is the line from space officials.
US specialists at the Joint Force Space Component Command said they had used orbit analysis technology to confirm Tiangong-1's re-entry.
Astronomer Jonathan McDowell, from the Harvard-Smithsonian Center for Astrophysics, tweeted that it appeared to have come down north-west of Tahiti.
Experts had struggled to predict exactly where the lab would make its re-entry - and China's space agency wrongly suggested it would be off Sao Paulo, Brazil, shortly before the moment came.
The European Space Agency said in advance that Tiangong-1 would probably break up over water.
It stressed that the chances of anyone being hit by debris from the module were "10 million times smaller than the yearly chance of being hit by lightning".
It's not clear how much of the debris reached the Earth's surface intact.
