Monkey is a common name for primates. With the development of space technology, the country will use monkeys for space exploration missions, including the United States and France. The first monkey sent to participate in space exploration is Albert II, which joined the V2 rocket launched by the United States on June 14, 1949.
Although people have gained long-term experience in manned spaceflight, there are still many problems that are not completely clear. In order to ensure astronauts to live and work healthily in the air, many countries have formulated life science flight experiment plans. The biosatellite used for this research is equivalent to a space biology laboratory, which can study the effects of weightlessness, overweight and other space environments on biological growth, development, metabolism and genetics and their protective measures, and can reveal biological problems that cannot be found under ground conditions. People have experimented with insects, frogs, white mice, rabbits and dogs. During the in-depth stage of manned spaceflight, scientists found that the physiological and anatomical characteristics of monkeys, in addition to cardiovascular data, can be inferred from humans. In this way, people generally focus on monkeys. In 1985, when the US space shuttle Challenger was launched, it carried two monkeys and a group of mice for further biological experiments in space.
In 1987, the Soviet Union launched a satellite and decided to use two monkeys to study cardiovascular, semicircular canal function, advanced neural activity, skeletal muscle and biological rhythm. They put each monkey in a cylindrical cockpit. In flight, oxygen supply and carbon dioxide removal are realized by the combined air regeneration system. There are certain requirements for environmental parameters in the cabin to maintain a certain temperature, humidity, oxygen and carbon dioxide in the cabin. Food is a semi-liquid paste, which is supplied twice a day. The ingredients include casein, butter, vegetable oil and large oil
Rice, barley flour, potato starch, sugar, apples, raisins, eggs, tea, salt and vitamin mixture. In the whole process, various instruments were used to measure the monkey's body temperature, heart rate and leg muscle electromyography
The amount of food and juice consumed and operation activities were monitored, and very valuable data were obtained. It can be predicted that monkeys will make important contributions to human spaceflight
