nasa space shuttle

Space shuttles and spaceships were both used in the aerospace field, but they had many differences. ** I. Concepts and Basic Principles ** 1. ** Space Shuttle ** - The space shuttle was a re-usable aircraft that transported people and cargo between the Earth's surface and low-Earth orbit. It was composed of an orbiter, a propeller, and an external tank. It was propelled into orbit by a rocket, and when it returned to the ground, it glided down like a glider. 2. ** Spaceship ** - A spacecraft (also known as a manned spacecraft) was a large spacecraft that ensured that astronauts could live, work, and perform space missions in outer space and safely return to the ground. It was generally composed of a return capsule, a service module (propulsion module), an orbital module, an emergency rescue device, and other components. It needed to be launched by a rocket, and after it was in orbit, it would be braked. It would pass through the atmosphere along a ballistic or semi-ballistic trajectory to achieve a soft landing with a parachute and landing buffer system. ** 2. Comparing the characteristics ** 1. ** Reusable ** - [Space Shuttle: Reusable. This is a major advantage.] For example, the space shuttle in the United States, after completing the mission, could perform the mission again after inspection, maintenance, and testing. In theory, it could reduce the cost of space transportation. However, every time it completed a mission, it had to be completely overhauled, which extended the mission period. - ** Universe ship **: Usually for one-time use. For example, China's Shenzhou spacecraft and Russia's Soyuz spacecraft were disposable, but the difficulty of manufacturing and maintenance was relatively low. 2. ** Function Diverse ** - [Space Shuttle: Various functions.] When in orbit, it could complete a variety of tasks such as releasing satellites, recovering and repairing satellites, and microgravity experiments. It could also transport large equipment into space. For example, in April 1990, the United States Space Shuttle "discovery" sent the Hubble Space telescope into orbit. Moreover, the mission was flexible and could perform more complex tasks such as repairing and recovering satellites. - Spaceship: Its function is relatively simple, mainly to ensure that astronauts live, work, and perform space missions in outer space and safely return to the ground. It is difficult to complete complex missions in orbit and it is difficult to stay in space for a long time. 3. ** Security ** - Space Shuttle: Judging from the accidents of the Challenger and Colombia, the safety of the space shuttle was a larger and more detailed system engineering. The system was highly complex, and the operation was also more complicated. It required more in-depth and comprehensive training for astronauts. - ** Spaceship **: Spaceships are easier to design and install escape towers and other escape equipment to increase the survival probability of astronauts. 4. ** Type of goods transported ** - Space Shuttle: Not only can it transport people, but it can also transport large equipment into space. - ** Spaceship **: It can transport a wide variety of goods, but it may not be as convenient as a space shuttle in transporting large equipment. ** 3. Development of each country ** 1. ** Space Shuttle ** - So far, only the United States and the Soviet Union had built and tested a complete space shuttle, and the United States was the only country that had successfully carried out a manned mission with a space shuttle. China was currently exploring space shuttle technology, such as the Haolong cargo space shuttle program. 2. ** Spaceship ** - The world's major spacecraft projects included the United States 'Orion spacecraft, Russia's Soyuz spacecraft, and China's Shenzhou spacecraft. China's Shenzhou spacecraft had successfully carried out many manned space missions and made important contributions to the development of China's space industry.

Hao Long No. 1 was a type of commercial spacecraft that could be reused. It was independently developed by the Chengdu Institute of the China Aerospace Industry Corporation. It adopted a large wingspan, high lift-to-drag ratio, and a re-usable aircraft technology. The launch method was to launch it into orbit through a launch vehicle, rendezvous and dock with the space station, then leave the space station for de-orbit braking and re-entry flight. Finally, it could land horizontally on the airport runway like an airplane. After inspection and maintenance, it could perform the mission again. The Hao Long-1 cargo space shuttle was positioned as a low-cost, re-usable space station cargo transport aircraft, taking into account the characteristics of both spacecraft and aircraft. It would work with Tianzhou, canoes, and cargo spaceships to build a flexible, efficient, diverse, and low-cost space station cargo transportation system. The space shuttle had a warehouse inside, but the space inside was small, only 20 cubic meters. China was still conducting follow-up research and development work on it. Its appearance was expected to solve the problems of high launch costs and long cycle of cargo spacecraft such as Tianzhou-1, and its downstream load capacity was relatively strong (although the specific data had not been released, the chief designer said it was excellent). It could help reduce space transportation costs, improve space efficiency, and bring back equipment and experimental results that needed maintenance on the space station.

The sci-fi space shuttle concept contained many elements of imagination. From the available information, one aspect was about the re-usable aircraft. It could take off from the runway like an ordinary plane. For example, China's Haolong cargo space shuttle concept had such a feature. This kind of space shuttle could fly into the sky and dock with the space station. Then, it would land like a glider to transport cargo for the space station. On the other hand, the concept of a next-powered space plane was also proposed. Using controllable nuclear fusion technology, it was envisioned as a future space bus for interstellar travel, but at present, it existed more in virtual screens such as UE5 animations for entertainment. There was also the concept of the "Mystic Fairy" space shuttle. It was envisioned to change the form of future air combat and was part of the Southern Heavenly Gate project. Although it was currently a sci-fi deduction, it also reflected the sci-fi imagination of the space shuttle concept in military operations, including the construction of combat systems with motherships. In short, the sci-fi space shuttle concept combined the ideal state of aerospace technology, future space exploration, and combat needs. The novel "Hundred Years of Spaceship" is equally exciting.

The space environment had a profound and complex impact on the health of astronauts. NASA had astronauts in space, such as Sunita Williams and Barry Wilmore, who had stayed for 153 days as of November 6 and at least until February 2025 (the original plan was eight days). Studies have shown that the microgravity environment in space can cause astronauts to lose body fat, muscle, and bone density, and they are exposed to high doses of radiation, which may cause a series of health problems, such as being more susceptible to infection. In order to maintain muscle mass and bone density, astronauts exercised for at least two hours a day, which consumed more calories. Therefore, the daily intake of calories was at least twice that of Earth to maintain weight. Williams 'weight loss might be related to insufficient calories. She was a keen runner and had run marathons in space. Also, NASA research showed that space travel had a more serious physiological impact on women. Female astronauts lost muscle faster than men. However, a photo of Williams on September 24th showed her sunken cheeks. Some doctors thought she might have been seriously lacking calories for some time, but NASA insisted that the astronauts on the space station were in good health, saying that the astronauts were undergoing routine medical assessments and were monitored by specialized flight surgeons. However, public concerns were not groundless. NASA's statement was clearly trying to calm public concerns. The novel "Hundred Years of Spaceship" is equally exciting.
