Why did a mirror thrown by astronauts in space cause concern to scientists?

Because the mirror has become space junk, there is a high probability that it will crash into the artificial satellite and cause damage to the artificial satellite.

Because it will become space junk, and if it is affected by force, it may also cause damage to artificial satellites, which is a great loss.

Losing a mirror, although it becomes space junk, has a great impact on astronauts and spacecraft, because a small mirror can help astronauts increase the accuracy of battery replacement.

Naturally, it can't, such an idea is completely whimsical. Because the distance between space and the earth can only be detected with the most scientific and advanced telescopes. With the current observation ability of human eyes, it is impossible to see things in space, because the distance between the earth and space is very far.

At present, mankind's exploration and research of space and the research results obtained so far rely on the most advanced scientific research machines, and it is impossible to explore space if it only relies on manpower. Similarly, in the current state of human health, the farthest distance that the eye can see into the world is only a few hundred meters. Telescopes are needed to make observations at longer distances, otherwise the human field of vision is very small.

Not to mention whether human beings have the level of production technology to make such a large area of mirrors to be placed in the sky above the earth, even if the reverse mirror can be placed in the sky above the earth, human eyes cannot see themselves in the mirror at present. <>

The distance between Earth and space needs to be calculated in light years, and it is difficult for even a spacecraft to fully traverse such a distance. In the middle of the earth and space, there are many substances unknown to mankind. The existence of these substances will largely hinder human observation of space.

Moreover, the current level of science and technology of mankind has made a certain degree of progress in the study of space. But for space, human beings are still very small. The distance that can be observed by the naked eye is only a few hundred meters, while the distance between space and Earth is hundreds of millions of light years.

With such a gap, it is simply impossible for human beings to see themselves in the mirror above the earth. In life, when a few meters away from the mirror, human beings can no longer see themselves in the mirror, let alone in the mirror above the earth. <>

Just so that they have enough safety when they land.

Astronauts go to space with guns just to be able to facilitate their work

No, it's just for work

yes, they're afraid of encountering something strange.

No, it should be for self-preservation.

Yes, what is there to prevent in case.

It's not counting, it's just a guarantee.

I think that's part of the reason.

No, it's to work better in space.

What if you come across something you don't know?

Would you believe me if I said that mirrors are standard for spacesuits?

Spacewalks are a risky affair for astronauts, and even in spacesuits, the zero-gravity vacuum environment can still expose astronauts to higher blood pressure. During a field mission today, Chris Cassidy and Robert Behnken had an accident while they were walking together when they lost a small mirror to make a liquid play.

Due to the helmet's poor field of view, astronauts need to use small mirrors to see difficult angles. However, CNN reported that shortly after the hatch opened, the utility gadget, which Cassidy was wearing on her left wrist, began to come loose.

Thankfully, the accident didn't have much of an impact on the mission. Through a series of spacewalks, the two will replace aging nickel-metal hydride batteries with new high-capacity lithium-ion batteries.

As for the escaped mirror, its ultimate fate may be to disappear when it falls into the Earth's atmosphere.
