Has There Been a Loss of Control?
Where will Tiangong-1 reenter?
How Difficult is it to Accurately Predict a Reentry?
Will objects from this reentry hit me or my property?
As all these questions can only expose how biased and ill-intentioned the Western propaganda machine is, hell-bent in smearing the ever more outstanding Chinese space achievements (due to desperation and jealousy as always), let us reassure all our Pakistani readers and Israeli hasbara as well, with some clarifications.
China has been working on developing laser weapons since the 1960s, and the People’s Liberation Army in 2015 published the book Light War that gives a central role to fighting a future war using lasers.
As already disclosed by the media, China is known to have operated at least 3 ASAT laser stations, in Anhui, Sichuan and Xinjiang.
In 2005, Chinese researchers have successfully conducted a satellite-blinding experiment using a 50-100 kilowatt capacity mounted laser gun in Xinjiang province. The target was a low orbit satellite with a tilt distance of 600 kilometers. The diameter of the telescope firing the laser beam is 0.6 meters wide. The accuracy of acquisition, tracking and pointing is less than 5 microradians.
Three researchers, Gao Minghui, Zeng Yuquang and Wang Zhihong disclosed plan for even more powerful ASAT lasers in The Chinese Optics journal in December 2013.
All worked for the Changchun Institute for Optics, Fine Mechanics and Physics – the leading center for laser weapons technology.
The plan proposed the building of a 5-ton chemical laser as a combat platform capable of destroying satellites in orbit. Given funding by the Chinese military, which is in charge of China’s space program, the anti-satellite laser could be deployed by 2023.
Although high secrecy is strictly enforced, one could compare the case of Tiangong-1 space laboratory with the ill-fated Phobos-Grunt Mars probe, that reentered over the South Eastern Pacific Ocean on 15 January 2011.
There was no random reentry over highly populated area. This time Tiangong-1 will also reenter over the Pacific Ocean, in a
remotely controlled mode.
This suggests that China will secretly use its laser ASAT stations, to produce a thrust generated by heating the outer part of the spacecraft, thus lowering the perigee of Tiangong-1, when it had finally reached the ~140 km altitude threshold. This would eventually allow a safe reentry half an orbit later over the predesignated area over the Pacific Ocean.
This is the least China could do, as even North Korea has already disclosed its own Korean-style Anti-Meteor Laser System, needed to protect its planned future Lunar base, back in a New Year 2018 show!

Notice the similarity with Tiangong-1 regarding the relative location of the impact zone and the ASAT laser stations!

Descent of China’s Tiangong-1 will not cause damage to earth: expert
March 14, 2018
According to the latest information issued by China’s manned space engineering office, since Feb. 25 to Mar. 4, 2018, Tiangong-1 was orbiting in stable condition and good shape at an average height of about 251.5 kilometers (perigee height: 238.6 km; apogee height: 264.4 km; orbital inclination: 42.79 degrees).
China has been monitoring Tiangong-1, Zhu said, adding that the space lab will burn up after entering the atmosphere and the remaining wreckage will fall into a designated area of the sea, without endangering the Earth’s surface.
Aerospace expert Pang Zhihao explained that an international tradition to handle retired large spacecrafts operated at near-earth orbits is to let them fall to an abyssal zone in southern Pacific Ocean far away from the continents.
Being called the “graveyard of spacecraft”, the water was the falling location for Mir space station and Progress spacecraft of Russia, and the Compton Gamma Ray Observatory of the US, Pang added.

Since the hasbara boy keeps reposting the same litanies again and again all over the forum, let me reveal the following, confirming my previous assessment:
The Chinese PLA ASAT laser stations seem to have already proceeded with their first in a series to come corrective laser surgical pinpoint accuracy strikes, as shown in the sudden
increased decay rate of Tiangong-1 witnessed by the official TLE of March 12!
▲ It is clearly visible an anomalous burst from the TLE 18070.1268 (March 11) to 18072.1107 (March 13), 6 consecutive TLEs.
▲ After the big variation in the decay rate on March 12, the totally controlled reentry is predicted at a slightly earlier date: 2-3 April 2018
▲ Groundtrack of a very good pass of Tiangong-1 over China's laser stations on 12 March 2018, especially a frontal approach over Tianshan ASAT station!
Coincidence? I think not!
