the space people

In space, people were in a state of microgravity or weightlessness. The concept of "flying" in this environment was different from on Earth. In the microgravity environment of space, people could move in some ways, such as using the handrails, foot pegs, and other facilities inside the spacecraft to push, so that they could float inside the spacecraft. In a sense, it could be seen as "flying." If the astronauts wore special spacesuits for extraterrestrial activities (EVA), they could use jetpacks to control their direction and speed, which was similar to flying. Therefore, people in space could achieve something similar to "flying" through specific means. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!

In space, people were in a state of weightlessness and would not " fall " like on Earth. There was almost no gravity in space. The spacecraft moved in a circular motion around the Earth and other celestial bodies. The centrifugal force generated was balanced with the gravitational force of the celestial body on the spacecraft and the people inside, so that the astronauts were in a state of weightlessness. For example, in the International Space Station or China's space station, astronauts could float freely in the cabin without worrying about falling to the ground from a high place like on Earth.

People in space could survive under certain conditions. From the practical experience of space exploration and related research, many countries have carried out extraterrestrial survival experiments to explore the possibility of human survival in space. For example, the Bios - 3 system proposed by the former Soviet Union in 1972 completed a 180-day survival experiment for 23 people in 1973. There were two biological chains in this system, humans and plants. Plants were responsible for producing oxygen and a portion of food, while water and most nutrients were provided outside the cabin. The Controlled Biological Life Support System (CELSS) established by the United States had completed a four-person, 90-day closed experiment. The European Space Agency's Microecological Life Support System Research Program introduced a variety of microorganisms to decompose human excrement to provide carbon dioxide, nitrogen rich medium, oxygen, water, and other substances for plants. The Japanese plan introduced goats, whose milk provided protein for humans, and goats consumed dead leaves and straw produced by crops. In the space station, astronauts survived through a series of measures. For example, in the scene described in the movie "The Mars Rescue," astronauts used Martian soil and human excrement to grow potatoes in the cabin during their 40-day extreme survival period. They also burned helium to produce water to maintain the water and air circulation in the station. Moreover, all waste on the International Space Station had to be processed and reused. Astronauts 'urine would be collected and processed until it reached safe drinking standards. Growing crops in space also required the use of human-generated waste as nutrients. In addition, scientists also discovered that fish could be an important resource for future space survival. For example, the remaining parts of the carp (bones, scales, internal organs, etc.) could be converted into complete plant nutrients for plant growth. An envisioned aquarium could provide fertilizer for space station crops and provide a source of protein for astronauts. At the same time, there were also many space survival games, such as "Generation Exile," which constructed a space survival scene from the perspective of the game, which indirectly reflected the exploration and thinking of human beings on space survival.

In space, a person could be in a floating state and look like they were flying. This was because space was a microgravity or weightless environment. There was no gravity like the Earth's surface that bound people in a fixed position or caused them to fall. For example, when astronauts walked in space outside the space station, they would move in this microgravity environment, as if they were "flying" in space. However, this kind of "flight" was different from the concept of flight on Earth, which relied on one's own strength to overcome gravity. It relied more on external forces (such as jet propulsion devices) or the initial launch force to move and float in space. The novel "Hundred Years of Spaceship" is equally exciting.

Since the first manned space flight in 2003, China had completed 11 manned space flights from Shenzhou V to Shenzhou 15, sending a total of 24 astronauts into space. From Shenzhou V to Shenzhou 18, a total of 22 astronauts were sent to space, a total of 35 people. The first batch of astronauts had nine people, and they went to space 17 times in total. The second batch of astronauts had seven people, and they went to space 12 times. The third batch of astronauts had six people, and they went to space six times. If we only count the astronauts who have actually carried out manned space missions and gone to space, so far, a total of 14 astronauts have been to space. As of 2024, there were 44 active China astronauts, but not all of them had performed space missions. The novel " Hundred Years of Spaceship " is equally exciting.
