The Chinese space station Tiangong-1 is now hurtling toward the Planet Earth and it is expected that the uncontrolled and falling space station will enter into Earth’s atmosphere near around 20th March to 2nd April. Now, scientists observing the space station to predict where it will crash. German scientists at the Fraunhofer Institute for High-Frequency Physics and Radar Techniques (Fraunhofer FHR) are observing its route through a tracking and imaging radar system. The scientists stated that that radar is one of the most powerful radar systems. The powerful radar is currently being used by the German Space Situational Awareness Center and European Space Agency (ESA).

When the scientists took the radar image of the spacecraft, that time it was moving at around 18,000 mph/h and the distance from the earth was 270 kilometers. They also examined the rotational speed of Tiangong-1. As per the scientists, the rotation will help them to know when the space station will collide with Earth. Previously it was informed that the space station may fall between 43 degrees north and 43 degrees south latitudes, which is covered with water and some of its parts may hit the ground.

Stating more into it Fraunhofer FHR stated, “A more accurate point of impact can only be estimated a few days previous to the actual event.”  There is a number of factors that can affect the space stations impact. Those factors include the rotation speed, the manner in which it will break into several parts and weather conditions of space.” The radar system used the Ku-band and i-band radio frequencies to track the position of Taingong-1.  The scientists are now doing regular checks to verify whether it is still fully intact or not.

It may be noted that the first Chinese space station was launched in 2011 and hosted Shenzhou 8 and two crews of Chinese astronauts on the Shenzhou 9 and Shenzhou 10 missions.
