"Removing tools in space" poses a threat to astronauts

Everyone will lose something such as a pen or eraser. However, in the universe, eliminating such tools is a big threat. Former astronauts talk about what it means to lose things in space.

Vanguard No.1Was launched in 1958, the world's first satellite equipped with a solar panel. I continued to send signals for 7 years from the earth orbit, but communication ceased in 1984, after that there is no purpose and it is drifting on orbit.


That means that "body garbage" with a body diameter of 16.5 cm and a weight of 1.47 kg is drifting through the universe. Besides Vanguard 1, there are millions of cosmic garbage such as parts of rockets, fuel tanks, and batteries. And until then, even things that were functioning with purpose will change to "threats" for astronauts when they become space garbage.


Below isSTS-121Pictures taken during the.


Working astronauts.


I am working onPears SellersMr. Cosmic garbage is made even if the spatula etc. used for such work are lost.


Since the translation is different from losing Hera in outer space because it is different from losing on Earth, "loss of Hera" was announced as a serious matter from NASA.



The place has changed, Chile is the state-of-the-art base of astronomy.


Fabiola Rojas and Carmen Martinez, Director of the Corowalla Female Observatory.


"How did he feel when he lost such a thing, because he knows that hundreds, thousands of similar things are drifting on orbit," Mr. Martinez I will talk.


Hera drifts at 17 thousand miles per hour (about 28,000 kilometers) as well as other space waste and eventually burns by entering the Earth's atmosphere.


Sellers who talks about the time, "We lamented when I realized that I lost the spat."


Space garbage can cause harm to astronauts, so sometimes it is necessary to evacuate and monitor in the shelter to avoid cosmic garbage.


There are things of this size in space rubbish ... ....


There are things that are too small to be seen by the eyes. However, because it moves at a very fast speed of 1 to 2 miles per second (1.6 to 3.2 kilometers), it is very dangerous to collide.


The astronauts evacuated to avoid small pieces ......


Once the green light comes out, I will work outside again.


If the three-dimensional space is much larger than the object, the two objects flying at random do not collideOzora theory, It is extremely unlikely that the unseenly small cosmic garbage will collide with the astronauts. However, the space garbage still seems to be regarded as a caution for the astronauts.


Some space garbage such as former satellites have been destroyed by colliding with active satellites already. However, large cosmic waste creates more cosmic waste by being destroyed. In addition, there is a possibility that possibility of depriving the power of the active satellite by collision is considered.


If you launch a rocket that orbits the Earth, space garbage is certainly born. Of course there are burnout parts in the atmosphere and parts falling on the earth, but of course there are parts that will remain in the universe and continue to drift forever.


When the satellite is separated from the rocket ......


In Bangkok, Thailand, the man is witnessing that the man "burned?"


A ray of light that flows in the sky. It is a beautiful sight from the ground.


Parts that burn fire in the universe ......


It becomes a shooting star on the ground.


And it falls to the sea. There are some things falling into the sea instead of being cosmic garbage.


With space debris of more than 10 cm, as of 2017 there are about 16,300 items floating around the earth.


If it is 5 cm or more, it is 60 thousand pieces ...


When it becomes 1 mm or more, it becomes 200 million pieces.


If it is more than 0.1 mm, it is estimated to be 1 trillion units. These cosmic garbage are thought to be recoverable by using things like harpoon, magnet, net, and in the future it is considered to reduce the threat of the universe. However, as of 2017 it is also true that there is no collection method.


"Vanguard 1 was the first artificial satellite we launched for the first time by the United States, she is still in the universe while rocking a small antenna, turning around in a vacuum space and doing nothing now, but we do not do anything As far as I know, I keep on perfect form, but some day someone will go to space to go to space and catch her, "says Cellers.
