What is the ultimate fate of the astronaut s wrist mirror floating away in space?

The astronaut in space, Wan Jing, will continue to reduce his altitude under the action of slight resistance in space, because there is no attitude adjustment and power propulsion system on it, it can only gradually accelerate into the atmosphere, and in the friction with the atmosphere to produce high heat and burn up.

Reference News Network reported on June 28 that a spacewalking astronaut added new garbage revolving around the earth on the 26th local time, and he just walked out of the International Space Station and planned to replace the battery when he threw away a small mirror, according to the Associated Press on June 26**, Commander Cassidy said that the mirror floated away at a speed of one foot per second, and the U.S. Space Flight Ground Command Center said that the mirror somehow fell off Cassidy's spacesuit, The mirrors that the NASA had lost posed no danger to either the spacewalk or the space station.

The astronauts who carry out the spacewalk wear a wrist mirror on each sleeve in order to get a better view while working, this mirror is only 5 inches, and with the addition of the strap, the mass is less, this is the fate of the small mirror that is discarded, and how it ultimately depends on its quality. The ISS operates in a vacuum environment 420 kilometers above the Earth's surface, and its orbit slowly descends due to its vacuum microgravity and atmospheric drag. But no matter how small it is, there is resistance, and this resistance can allow the space station to land at a height of about tens of meters every day, so that the space station can overcome the resistance, maintain its orbital altitude, and stand firmly at an altitude of 400 kilometers, for which scientists have designed a small thruster.

Thrust is generated by the magnetic field that accelerates the ionized air, and a small force in space can allow a satellite of several hundred kilograms to fly a long distance.

The role of tiny power thrusters is huge, and in the field of space exploration, it can make spacecraft dock with the space station, operate stably in space, and can also propel Mars probes or other vehicles to fly to other planets to explore unknown space.

The ultimate fate of the astronaut's wrist mirror that floated away in space was to burn up, and under the slight resistance of space, it continued to descend to the atmosphere, generating heat in the friction with the atmosphere, and then burning and destroying.

The astronaut's wrist mirror floating away in space will be affected by the action of the small force in space, constantly reducing the altitude, because there is no adjustment system on it, it can only gradually accelerate into the atmosphere, and rub against the atmosphere and burn up.

The final fate must be destroyed, a small mirror cannot withstand the pressure of space, because it keeps falling, and finally can only reach the atmosphere and be destroyed.

In weightlessness, the astronaut's wrist mirror should quickly drift towards the depths of the universe, and in the process, it may be attracted by the gravitational pull of other planets, which will accelerate the fall on this planet.

There is a vacuum in space, there is no oxygen, and the astronaut will eventually run out of oxygen in the spacesuit and die.

The wristscope eventually descends gradually, enters the Earth's atmosphere, and eventually burns out.

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