Photograph of the 8.5 ton Chinese space station about to fall to Earth

The falling image of China's 8.5-ton heavyweights entered radar's view at an observatory in Germany.

The Fraunhofer Institute of High Frequency Physics and Fraunhofer Radar Technology published two radar images of Thien Cung 1, a Chinese space station that is losing control toward Earth, according to Newsweek. Researchers at Fraunhofer FHR took photos in early February, using the Radar Tracking and Photography Observatory (TIRA) in the Wachtberg municipality near Bonn, Germany.

TIRA is one of the world's most powerful radar stations. The European Space Agency (ESA) commissioned the Fraunhofer FHR to use the device to monitor Thien Cung 1. Recent astronomers have narrowed the station's fall time in about two weeks between March and April. , coincides with the upcoming occasion.

On March 22, Aerospace Corporation predicted that Thien Cung 1 station would fall back to Earth around 1/4 with a difference of three days. ESA also predicts the station will fall between March 30 and April 3 . This prediction is updated 1-2 days and still "has large fluctuations" , according to ESA.

The TIRA observatory will help narrow the estimate of the day the station falls back. The Radar of the Fraunhofer FHR will help determine how the Thien Cung 1 station rotates, an important factor affecting the flight path of the station. The Fraunhofer FHR also regularly checks whether Thien Cung 1 station is intact.

The yellow area is the most likely place to fall, the less dangerous the green is, the more blue the sea cannot fall.

Although no one knows exactly where the Thien Cung 1 station falls, experts predict the station will land in about 43 degrees north latitude and 43 degrees south latitude. The area encompasses a number of US mainland locations, cutting through Oregon, Michigan and New York.

Most of the space stations will burn in the process of falling, and the remaining fragments are difficult to hit people. In fact, the chance of a person being shattered by Thien Cung 1 station is a million times smaller than the ability to win a lottery.
