What equipment is installed on the second-generation salute space station?

On the second-generation salute space station, many new equipments have been installed, among which the most interesting is the "space stadium" for astronauts to exercise. There are many strange sports equipment in the stadium, such as:

Bicycle dynamic recorder can't move forward without wheels. Instead, there is a lightweight forging plate combined with plastic on the floor roller. When people step on the board, their bodies are fixed by four elastic safety belts. They hold the handlebars and step on the pedals. At the same time, the "power" of the pedal is recorded and displayed by the sensor, and it is stipulated that astronauts "ride" for not less than 4 ~ 4.5 kilometers every day.

Micro runway is a kind of belt runway. As soon as the astronauts run on it, they will be pulled back by the belt tension of about 490 cattle, forcing them to "run forward" continuously, but they are actually in the same place. Run not less than 3 ~ 4 kilometers every day.

Negative pressure pants This is a special spacesuit. Put on this suit, turn on the special pump, pump out the air in the pants, let the blood flow from the head to the lower limbs, increase the load of the human body, overcome the influence of weightlessness and redistribute the blood.

There are "ejection tensioners" and so on. These devices have automatic recording devices and send them to the ground command center in time, so that space doctors can grasp the astronauts' physical condition in time.

The work module is the center of the space station. The cabin is equipped with various instruments and equipment, control center, teletypewriter and astronaut exercise facilities, medical monitoring equipment, sanitary equipment, waste storage containers, two remote-controlled cameras and so on. The transition cabin is equipped with astronomical observation, orientation equipment and photographic control equipment. All biomedical equipment, as well as spectrometers, multispectral cameras, two black-and-white in-station cameras, three off-station cameras and 1 color cameras are installed in the inter-cabin part of the transition cabin and the working cabin. The service cabin is cylindrical. The service cabin is fixed behind the working cabin by bolts. The cabin is equipped with motor-driven orbit-changing engine system, fuel tank, gas cylinder, power supply line equipment, attitude control engine, rendezvous beacon, TV camera, flashing signal lamp of docking device, radio antenna system, solar cell windsurfing and equipment facing the sun. Three large solar panels are installed outside the working cabin of the orbital station. These windsurfers spread out on their own after the men's track and aimed at the sun respectively. The unfolded windsurfing also plays a role in stabilizing balance and preventing the space station from overturning. The photovoltaic cell area of three solar panels is 60 square meters, which can provide 4000 watts of electricity.

Salute 6 not only carried out a series of military reconnaissance activities, but also carried out a series of space science research activities. For example, take photos of central and western Siberia and observe polar ice, ocean, land, floods and forest fires in Africa. In astronomical observation, astronauts use infrared telescopes and small optical telescopes to observe the movements of Jupiter and Sirius, the center of the Milky Way, the Orion Nebula, interstellar hydrogen clouds, the Northern Lights over North America and Canada, and measure the infrared radiation of the upper atmosphere and its weather forecast. Manufacturing of space materials, welding and manufacturing of new synthetic materials and semiconductor materials under weightless conditions in space; The diffusion process of metal melting under weightlessness was studied. Biomedical experiments have studied the reproduction of tadpoles in space environment, made experiments on the growth of algae balls and observed the cardiovascular system of astronauts.
