Space laboratory falls from orbit and incinerates in Earth's atmosphere in an awesome movie | Science | News


Most of the space laboratory incinerated in the Earth's atmosphere upon re-entry. And a small amount of space debris fell in a designated area in the South Pacific. Tiangong-2 has been in orbit for more than 1,000 days, much longer than the expected life of two years, after launch from the Jiuquan Satellite Launch Center in September 2016.

During that time, he has hosted two astronauts for 30 days and has conducted several cutting-edge scientific experiments.

Zhu Zongpeng, chief designer of the space laboratory of the China Space Technology Academy, Tiangong-2 was in good condition and could have remained in orbit for several more years.

However, the decision was made to deorbit the space laboratory "responsibly", before it became too old.

Zhu told reporters: "The voluntary retirement of Tiangong-2 is designed to eliminate all risks.

"Otherwise, the orbit reliability of the space laboratory will decrease as the extended service extends more than originally intended.

"Once some anomalies occur, Tiangong-2 will uncontrollably return to the atmosphere, and some parts may not be completely burned, with its debris falling to the ground, which poses a threat to people."

Tiangong-2 used a two-step strategy for its controlled de-orbit, ensuring that the descent took place at a designated time and place.

First, the space laboratory was reduced to an elliptical orbit of 200 km.

And then it descended to an elliptical orbit of 43 miles (70 km) before its ardent reentry through the atmosphere.

The planning of the Tiangong-2 orbit occurs after its predecessor, Tiangong-1, lost power in April 2018 and made an uncontrolled forced landing.

Tiangong-1 was supposed to be removed from service in 2013, but its mission was repeatedly extended until China lost communication with the ship.

Fortunately, the debris from the doomed spacecraft, which was traveling at 17,000 mph, fell into the ocean, avoiding casualties.

China is preparing to launch its third temporary orbital laboratory, Tiangong-3, which will be used to test key technologies.

The country's ultimate goal is to launch a "real" space station by 2020, which will allow China to play a more important role in space exploration by satellite, manned space flight and space control.
