The Chinese space station Tiangong-1 was launched in 2011. It stopped communicating with ground control back in March 2016. With no way to bring it down into a controlled descent, it is now slowly falling closer to Earth’s atmosphere. Scientists have only been able to wait for its orbit to decay and now it’s expected to tumble to the ground or ocean in the next few days.
Both amateurs and government agencies are trying to figure out where and when it will arrive. Some sites like SatView are running live streams of Tiangong-1’s current location and predict where it might fall to Earth.
The most current prediction at the time of this writing is Monday April 2 at 01:05 UTC. Check it out!
