If you fill up your eye and throw off a dart at a spinning globe , odds are you ’ll strike the Pacific Ocean . And that ’s just where the doom Chinese satellite Tiangong-1 land last night .
The infinite station reentered Earth ’s atmosphere over the Pacific Ocean , northwest of Tahiti , at 8:16 p.m. ET Sunday , the U.S. Strategic Command ’s ( USSTRATCOM ) Joint Force Space Component Command corroborate in a jam press release . This draw the planet ’s tenacious saga to a close , and highlights just how difficult it is to track where on Earth fall space debris might bring .
Many space fan and astronomers drop much of yesterday tracking the spacecraft through the USSTRATCOM ’s space-track.org , marvel where it might land . It end up pretty much exactly where many expected it to end up : the middle of the ocean .
China launched the school bus - size satellite in 2011 , but in 2016 inform the United Nations that it was n’t functioning . A European Space Agency - run consortium took to cut across the satellite , but was unable to bid a firm forecasting of where and when it would barge in back to Earth until just days before . Chinesedisputesthat the re - entry was “ uncontrolled , ” the words used by the rest of the world , report Space.com .
“ With our current understanding of the dynamics of the upper atmosphere and Europe ’s limited sensors , we are not capable to make very precise predictions , ” Holger Krag , head of ESA ’s Space Debris Office , said ina program line . “The eminent speeding of come back satellite have in mind they can go thousands of kilometres during that prison term window , and that hold it very hard to prognosticate a precise positioning of reentry . ”
As predicted , the spacecraft strike an uninhabited region of Earth , thoughthe blast ball possibly could have been visibleto some people in Korea or Japan prior to reentry .
This was a lot of hype for a relatively small object . Some previous uncontrolled reentries have involved much larger spacecraft , such as the 152,000 - pound sterling Skylab , parts of which hit Australia n 1979 . The Mir outer space place was also larger , but its reentry was command and it hit the Pacific Ocean .
Despite the loss of Tiangong-1 , China ’s space program remain apace — Tiangong-2 is still orbiting the Earth , and the country hopes to establish apermanent space stationby 2022 .
We ’re glad this is fuss finally over — now perhaps we can concentre on affair that , you know , will actually hurt people .
