1. air for scientific experiments, can not only rely on robots and the use of ground remote control methods to complete, many experiments are to be astronauts personally as subjects or operators to complete, astronauts in space experiments need some experimental equipment, which is the most widely used, the most important is the glove box.
2. The glove box is not an unfamiliar piece of equipment to those conducting scientific research on the ground; it is a sealed aluminum box in which both hands can be operated. Originally, this device was used in medical research, and was used by medical researchers to prevent viruses from infecting themselves while conducting experiments. After that, it became more and more varied and versatile, and was widely used in military, aviation, nuclear, medical and other fields.
3. Why do you need a glove box to conduct experiments in space? This is because the astronauts of the space experiment is in a microgravity environment, this environment brings a lot of problems. Imagine, if the liquid experiments in space, these liquids will never be as honest as on the ground to stay in the experimental containers, a little touch them, they will be from the container "escape" out of the air running around, so full of droplets, affecting the astronauts breathing, the more terrible thing is that if these droplets contain Worse still, if these droplets contain bacteria or microorganisms that jeopardize the human body, the first victims will be the astronauts. At the same time, some liquids will also hide in the equipment and slowly corrode the equipment, which is like burying a time bomb, not knowing when it will "explode". Another example, in the gas or smoke-producing experiments, astronauts can not be like on the ground as casually open the window near them, so that fresh air flow in. Spacecraft cockpit is a closed system, if you open the hatch, destroying the cockpit of the airtight, astronauts immediately exposed to the vacuum of space, the consequences are unimaginable. In short, floating contaminants from space experiments can endanger the crew and the spacecraft itself, and the scientists' first priority is to solve these problems, not to get the astronauts off the station, so the scientists came up with the idea of moving the glove compartment into the sky.
4. There's another reason for gloveboxes to conduct space experiments. Many experiments in space need to be carried out in a confined environment, if each experiment to develop their own required confinement system, you can imagine how much it would cost to develop and launch the equipment cost ah! Even if they were developed, they would not fit on the space shuttle or space station. Glove box is very wide range of uses, the use of a glove box can carry out a variety of medical, biological, physical, materials science and other experiments. In this way, scientists in the design of different space experiments, they do not have to develop their own experiments in the confinement system and power system, using the spacecraft in the *** with the glove box can be. At the same time, the resulting experimental data can be downlinked through the spacecraft data system connected to the glove box. This would make a space experiment much less expensive.
5. In the field of scientific research, the space station's glove box is like a freshly baked "hot meat and potatoes", favored by scientists from all countries, many countries and institutes of scientists have applied, want to carry out experiments on it. At present, the glove box of the International Space Station will carry out research in five microgravity areas: biotechnology, combustion science, fluid physics, basic physics and materials science. The future application of the glove box is bright, for example, it can carry out research on ferromagnetic fluids, which can be used as surgeon's "nano-mercenary" to destroy tumors by heating in the human body; it can carry out research on various material sciences to provide new materials for the Mars expedition; and it can carry out experiments on precise crystal solidification process to pave the way for the creation of a new generation of high-performance semiconductors. High-performance semiconductors to pave the way for the creation of a new generation. In short, space experiments will solve many unknown problems, the results of which are also attributed to the glove box.
