What is the power of a spacecraft in space?
There were many sources of power for a spaceship in space. - [Rocket engine: This is a type of jet engine. Its basic principle is to expel matter backward and use the recoil generated by the ejected matter as a driving force to move forward in space.] The rocket engine itself carried fuel (such as liquid hydrogen) and oxidiser (such as liquid oxygen). The two mixed together to produce powerful kinetic energy. The product of combustion was water, which could work even in space without air. During flight, it would gradually separate from the empty fuel chamber to reduce its weight and maintain its endurance. - ** Electric propulsion system **: For example, the ion thruster first ionizes the working medium into charged particles, and then through the Lorentz force generated by the strong electric field, the charged particles are ejected at an extremely high speed to obtain recoil. - Solar sail: It can be considered a "working-free engine". The basic principle is to use the "light pressure" of sunlight as a driving force. - ** The gravity of the planet **: For example, the Voyager used the gravity of the planet to provide power for spacecraft flying in the universe, especially spacecraft flying on Earth. This method combined with the power obtained when leaving Earth could provide enough power for the satellite. - Isotope battery: For example, the Voyager also carried an helium battery, which mainly provided long-term power for the electronic system in the spacecraft. However, this battery would run out of power. For example, the helium battery of the Voyager would end its power supply around 2025. - Solar Power System: It can convert the abundant solar energy in the universe into kinetic energy, which can drive the spacecraft to accelerate. However, the further the spacecraft is from the sun, the less solar energy it can obtain. - Nuclear Power System: Nuclear power is a powerful energy source. With the development of space exploration, it is expected to be applied to spacecraft. Humans now have next-powered aircraft carriers, next-powered submarines, and other next-powered equipment. - [Curvature Drive System: Currently still in the theoretical stage. The theory is to use the curved space structure to accelerate the spacecraft, using the characteristic of shortening the distance at the curved space to allow the spacecraft to cross the galaxy in a short time.] - [Antimatter Power System: Currently only available in theoretical physics. Antimatter has more powerful energy than nuclear energy. The energy released by a small amount of antimatter can supply the energy needs of a large city for decades. If it can be applied to the spacecraft power system, it will provide powerful power.] The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
China space spacecraft
China's spacecraft was the Shenzhou spacecraft, also known as the Shenzhou manned spacecraft. It was a manned spacecraft developed by China to transport people and materials to and from the world. The spacecraft consisted of an orbital module, a return module, a propulsion module, and an additional section. The orbital module was where the astronauts lived and worked; the return module was the command and control center of the spacecraft, and the astronauts took it to the sky and return to the ground; the propulsion module provided energy and power for the spacecraft to fly in orbit and return to the ground; the additional section was now used as the installation part of the rendezvous and docking mechanism. The development of the Shenzhou spacecraft reflected the continuous progress of China's aerospace technology. In September 1992, the central government decided to implement the manned spaceflight project and determined the "three-step" development strategy. In the same year, China Aerospace Science and Technology Corporation began to develop the Shenzhou spacecraft. Its first flight mission, Shenzhou I, was successfully launched on November 20, 1999. Its first manned flight mission, Shenzhou V, was successfully launched on October 15, 2003. As of 2024, many Shenzhou spaceships had successfully carried out their missions. For example, at 20:59 on April 25,2024, the Shenzhou 18 manned spacecraft was launched, and at 23:12 on October 16,2024, the Shenzhou 19 manned spacecraft was launched. These spaceships played a vital role in promoting the development of China's aerospace industry, conducting space application experiments, and building space stations.

The spacecraft is forced in space
The universe ship was forced in space. On the one hand, it would be affected by the gravity of various celestial bodies, such as the Earth's gravity. Although the gravitational force of the surrounding celestial bodies on the spaceship might be zero in some cases, gravity still existed. On the other hand, the propulsion of the spacecraft's own engine would also have a force effect on the spacecraft. According to Newton's law, if the spacecraft was moving in a uniform straight line, then the spacecraft might not be affected by any force (the external force was zero). However, if the spacecraft was not moving in a uniform straight line, for example, when it was moving in a circular motion around the Earth, the spacecraft would be affected by the gravitational force provided by the Earth.

The speed of the spacecraft in space
The speed of the spaceship in space varied according to the type of mission. Usually, the speed of spacecraft orbiting the Earth was between 7.9 - 11.2 km/s, such as Shenzhou 1 - 9, Tiangong, etc.; the speed of spacecraft flying to the Moon, Mars, or other planets in the solar system was between 11.2 - 16.7 km/s, such as Chang'e 1 and 2, the Mars probe launched by the United States, Apollo 1, etc.; the speed of spacecraft flying away from the solar system was greater than 16.7 km/s. In addition, the United States 'Juno Jupiter probe could reach a speed of 73.6 km/s, which was the maximum speed humans could travel in space. Usually, the spacecraft's speed was about 28,000 kilometers per hour. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
Shenzhou spacecraft and space shuttle
The Shenzhou spacecraft was a manned spacecraft developed by China to transport personnel and materials between heaven and earth. It was composed of an orbital module, a return module, a propulsion module, and an additional segment. The orbital module was where the astronauts lived and worked. The return module was the command and control center. The astronauts traveled back and forth in it. The propulsion module provided energy and power. The additional section was once used to install special equipment and was now used to install the rendezvous and docking mechanism. The first mission of the Shenzhou spacecraft, Shenzhou I, was successfully launched on November 20, 1999. The first manned mission, Shenzhou V, was successfully launched on October 15, 2003. The space shuttle was a vehicle that could be reused to transport people and cargo between the Earth's surface and low-Earth orbit. The system was composed of an orbiter, a propeller, and an external tank. It was propelled into orbit by a rocket. When it returned to the ground, it slid down like a glider and landed. When it was in orbit, it could complete tasks such as releasing satellites, recovering and repairing satellites, and microgravity experiments. The United States and the Soviet Union had built and experimented with complete space shuttles. The United States was the only country that had successfully carried out a manned mission with a space shuttle. In the early days of China's manned space project, the Shenzhou spacecraft and the Great Wall I space shuttle were proposed at the same time. In the end, the Shenzhou spacecraft was given a chance to develop due to its " small investment, small risk, and large grasp." China's choice to develop the Shenzhou spacecraft was correct. From the subsequent experience of the US space shuttle, even if the space shuttle did not explode, its " re-use " advantage was not obvious and the price was high.

How long did the American spacecraft fly into space?
The reference only mentioned that it took 28 hours for the Dragon spacecraft to dock with the space station, but it did not specify the flight time from launch to space. The time taken for different spacecraft to fly to space was also different. For example, SpaceX's Dragon spacecraft was launched on September 28 local time from California to the International Space Station, but it did not mention the specific flight time to reach space. The Mercury spacecraft made its first sub-orbital manned flight on May 5,1961. It flew at an altitude of 186 kilometers and a flight distance of about 480 kilometers. The flight time was 15 minutes and 22 seconds, but this was a sub-orbital flight and did not clearly indicate the concept time to space. Virgin Galactic's VS Unity spaceplane took off from New Mexico's spaceport on June 8th at 10:31 a.m. Eastern Time. After an hour of climbing to an altitude of 13582 meters, it separated and ignited the rocket engine to send the crew into space. However, this was a sub-orbital space flight and the exact concept time to space was not clear. Therefore, it was impossible to accurately answer how long the American spacecraft flew into space.
