China Space station lost control over Tiangong-1



Chinese space station "Tiangong-1" is in the limelight for some days. There are two maps for observing the test space station-one is a wider view of the world with Tiangong-1's larger flight path laid out in dotted lines, and the other is a closer look centered on the space station that shows the land and water below it at any given point. But now, it is making a comeback.

In 2016, the Chinese announced they had lost control of Tiangong-1, which was first launched in 2011, and that it would come falling to Earth sometime "in the latter half" of a year ago. After losing control over the space lab which has been falling towards the Earth researchers across the globe have been trying to pinpoint the exact location of its re-entry.

The date at which it will enter, be that as it may, there are sure requirements on evaluated the reentry date and destinations, for example, its speed with respect to the Earth, its turning and mass, and different parameters. On the flip side, the location where it will crash or plunge is still unknown and not estimated due to many reasons. It is because the space station revolves around the Earth several times per day which means, even a difference of few minutes can take the station to a completely different part. According to the estimates, the station might plunged into the Earth's atmosphere within 45-degree North latitude and 43-degree South latitude which is coincidentally the region with most human population that includes countries not limited to India, Australia, Brazil, United States, Egypt, China, Mexico, etc but the major portion of this region is covered with oceans.

Even if the space station plunges into a populated area, it won't cause much harm since it will burn upon entry.

"The personal probability of being hit by a piece of debris from the Tiangong-1 is actually 10 million times smaller than the yearly chance of being hit by lightning", the ESA said.

Despite the fact that scientists are as yet anxious about the poisonous substance that it may contain, for example, Hydrazine for which, even a follow sum if gets away from the Earth's climate can cause an issue.

Dr. Marco Langbroek has been tracking the fall of the space station for a few weeks now.

However, the drag from Earth's atmosphere that acts on objects at this height is not consistent, so pinpointing exactly when the space station, which is now orbiting at about 250 km above the planet, will begin its descent is very hard. According to the recent data collected and presented by a paleolithic archaeologist Dr. Marco Langbroek who is an avid satellite tracker, the space tab might make its re-entry in the Earth's atmosphere on March 31 give or take 3 days. He pointed out that the space station will start burning up at 100 km from Earth's surface and eventually initiate breaking apart at 70 to 80 km of altitude.
