Finally, on 19 July, China completed a controlled re-entry of the 8.6-ton Tiangong-2 space station over the Southern Pacific Ocean.
Efforts are being made to step up preparations for constructing China's space station, CMSA said. A small amount of the spacecraft's debris fell into the predetermined safe sea area in the South Pacific, it said.
Xinhua said the space lab has worked in orbit for over 1,000 days, much longer than its 2-year designed lifespan.
Tiangong-2, an improved version of Tiangong-1, is considered China's first space lab. After its solar panels are unfolded, its wingspan reaches 18.4 meters.More news: Boeing to spend $50 million to support 737 Max crash victim families
Following this, in 2017 the docking and refueling capabilities of the Tiangong-2 were tested and measured by having a cargo spacecraft dock on the space station three times.
As Tiangong-2's mission was never meant to last forever, and now that it has served its goal, even though nothing is wrong with the space station, China will bring it back down to Earth. "China will timely report the information about the spacecraft after it re-enters the atmosphere to fulfil its worldwide obligations", the CMSEO said.
Despite still being operational, the CSNA may have chose to retire the Tiangong-2 since it has already exceeded its mission period.
"To let Tiangong-2 "retire" by choice is to ensure the absolute safety of its departure", Zhu said. It's understood that Chinese authorities will make sure they have much more control over Tiangong-2's descent. Some materials with a high melting point might not be burnt out completely, and a small amount of debris would be possibly left hitting the ground and endangering the people in the vicinity, he explained.More news: It Chapter Two's New Trailer Will Give You Nightmares
All of the space lab's assigned tasks have been finished. China is planning to launch Tiangong-3 in 2020.
The spacecraft was in a stable condition at that time, state-run China Daily quoted the CMSEO as saying.
A space lab dubbed Tiangong-1 disintegrated as it plunged back to Earth in April 2018, two years after it ceased functioning. Two astronauts (called taikonauts in China) traveled to Tiangong-2 in October 2016.More news: New video confirms the final design of the upcoming iPhone
