Space technologies: how unique devices and materials help people on Earth

Scientists have created many unique devices and materials that are needed to work in orbit. But many of them have found their application in life on Earth. MIR 24 correspondent Maxim Krasotkin studied space technologies.

In a special suit, rescuer Andrei Himalov is always the first in the place of severe fires. The material from which it is sewn was used even in the first space suits for outer space. Only there, under the rays of the sun, the temperature is 200 degrees, and the firefighter's clothes are designed for all 400.

“Of course, you can't work in it for too long. Because we can get heatstroke. We need to work for some time and exchange with other guys, ”said firefighter Andrei Himalov.

The birthplace of this suit is also space. With its help, children with cerebral palsy form the correct gait. Due to the tension of the flagella, the necessary force is created on the legs and back. Its prototype was the “Penguin” suit, which the cosmonauts wore in zero gravity for the same purpose – to keep the muscles in good shape.

“We develop a gait stereotype. That is, if the leg is in the inward position, then due to the strips we bring it out, the work of the lower leg muscles increases, “said Olga Pobuta, deputy director of the Moscow City Rehabilitation Center. And this bath is called” dry immersion “. Here, a person literally hangs in the water column, as in weightlessness, separated from it only by material. The astronauts spent several weeks in these so that doctors could understand how the body reacts to the absence of gravity. It turned out that under conditions of dry immersion, the work of the heart improves. And now technology is helping those who have suffered a stroke.

Edible packaging: environmentally friendly cling film was created in the Urals. The film can be used for packaging meat, sliced fruits and vegetables.

A Soyuz rocket with a portrait of Gagarin was installed at the Baikonur site. The launch is scheduled for April 9th. It is timed to coincide with the 60th anniversary of the first manned flight into space.

“Tension is relieved, blood supply improves. And the blood supply is improved due to the fact that the mass of water that is displaced by the patient's body presses evenly on the entire surface of the body, ”added Olga Pobuta.

At first, until experiments in zero gravity became a system, observations from orbit were of value on Earth. For example, cosmonauts advised fishing vessels about the movement of huge schools of fish.

“Once they suggested a good fish spot, they said in plain text. While our fishermen got to this place, the Americans are already catching fish with might and main. They also eavesdropped on us. And ours have already come to an analysis. They classified it, began to encode the information, ”said the cosmonaut, twice Hero of the USSR, Boris Volynov.

Sometimes space experiments lead to unexpected results. Observing the behavior of dust particles in a plasma cloud, the astronauts saw that they repeat the structure of our galaxy, and if the plasma is cooled, the dust particles are arranged in a copy of a DNA molecule. The experiment was named “Plasma Crystal”. You can't repeat it on earth – attraction interferes.

“Partially there are some ideas on how to use the effects that were obtained as a result of this experiment. For example, a plasma crystal can be used for medicine, producing plasma that can be used to treat burns, oddly enough, ”noted cosmonaut, Hero of the USSR, Hero of Russia Sergei Krikalev.

It often takes years for the results of space experiments to be applied on Earth. Until recently, flat-panel monitors and tablet computers were fantastic; their creation was also pushed by flights into orbit, when bulky equipment in a cramped ship only interfered. Space is closer than it seems.
