What does spaceship mean and what does spaceship mean to humanity

Spacecraft. A single-use spacecraft where cargo reaches space and returns safely. It can basically ensure that astronauts can live in space for a short time and carry out certain work.

Its operating time is generally from a few days to half a month, and it is generally multiplied by 2 or 3 astronauts. The world's first manned spacecraft.

It is the Vostok 1 spacecraft. It consists of a two-defeat sliding module, and the top is a sealed manned cabin, also known as the astronaut cockpit. The cabin is equipped with a life support system that can ensure the water supply and gas supply for the astronauts' lives, an attitude control system to control the attitude of the spacecraft, and a beacon to measure the flight trajectory of the spacecraft.

systems, parachute systems** for landing, and ejection seat systems for emergency rescue. The other cabin is the rolling equipment cabin, which has a braking Chala rocket system that makes the manned module get out of the flight trajectory and return to the ground, and a battery for electric energy, a gas cylinder for gas storage, a nozzle and other systems. The total mass of the Vostok 1 spacecraft is about 4700 kg.

The Vostok 1 spacecraft opened the way for humanity to space.

Spacecraft. It is a celestial body, and the main reasons for this are as follows.

1. Because it operates in the universe, it is theoretically affected by many forces, such as the "blowing force" of the solar wind, the electromagnetic force, and so on.

2. The spaceship is prepared in the hall sail space, and the engine may work at different stages, but it may not work, and according to the knowledge of circular motion, when the spacecraft reaches the first cosmic velocity, the engine can be turned off, and it will turn around the earth without falling off the imitation voltan.

3. The spacecraft needs to use engines during the acceleration and deceleration phases, and as for returning to Earth, it only needs to slow down.

4. The gravitational pull of the Earth on the spacecraft.

Greater than the centripetal force required for the spacecraft to revolve around the Earth.

, the spacecraft will make a centripetal motion and gradually approach the Earth to land. Parachutes, thrust reversers, etc., are also used in this process, but the main principle is deceleration.

It is a celestial body, which belongs to the man-made file of the celestial body. Notice.

Encyclopedia definition: Astronomical object, also known as a star, refers to the body in space.

It is an artificial celestial body.

Hope mine is helpful to you and received by yours.

It's not a celestial body, it's an artificially created object.

"Spaceship" and "Electronic Calculator" represent modernization. In the poem "Yan'an, I Pursue You", the author uses the words "space shuttle" and "electronic computer" to represent modernization. Spaceships, electronic computers, these are the products of the development of modern science and technology.

Indicates the progress of our country. "Old cattle broken car" represents the backward production conditions in the past, the efficiency is very low, and the speed is very slow. The "backbone" represents the spirit of Yan'an.

What the author wants to pursue is actually the spirit of Yan'an.

"Yan'an, I'm Chasing You".Like a returning swallow, in pursuit of the spring of the past;

Like a thriving tree, chasing the rain and sun.

Chasing you, the flowing water of the Yanhe River, chasing you, the fragrance of pear blossoms in the jujube garden.

Chasing you, the head of Nanniwan's wasteland, chasing you, Yang Jialing took the spring cover to give a speech.

Rows of high-rise buildings have sprung up like mushrooms after a rain, and household appliances are full of noisy;

We said goodbye to the dilapidated thatched hut forever, but we can't forget the warm earthen kang in the Yan'an cave.

The space shuttle explores the mysteries of the universe, and the electronic computer plays a wonderful symphony;

We did not hesitate to throw away the old cow and broken cart, but we could not lose the backbone of the pagoda on the top of the mountain.

Yan'an, your spirit is brilliant!

If you lose you, it is as if you have no soul, how can you spread your wings and fly towards a better future?

Yes! Yan'an, I will pursue you, pursue faith, and pursue golden ideals;

Pursue warmth, pursue bright spring;

Pursue the light, chase the fiery sun!

A spaceship (Space Ship in English) is a single-use spacecraft that transports astronauts, cargo to space, and returns safely. It can basically ensure that astronauts can live in space for a short time and carry out certain work. Its operation time is generally a few days to half a month, and it is generally multiplied by 2 to 3 astronauts.

So far, mankind has successively researched and produced three types of spacecraft, namely, single-cabin, double-cabin and three-cabin spacecraft. Among them, the single-cabin type is the simplest, only the astronaut's cockpit, and Glenn, the first American astronaut, took the single-cabin "Mercury" spacecraft to the sky; The dual-cabin spacecraft is composed of a cockpit and a service module that provides power, power, oxygen and water, which improves the working and living environment of astronauts, and the world's first male and female astronauts to ride the former Soviet Union's "Vostok" spacecraft, the world's first astronaut to fly the former Soviet Union's "Ascend" spacecraft, and the United States' "Gemini" spacecraft all belong to the dual-cabin type; The most complex is the three-cabin spacecraft, which is based on the two-cabin spacecraft or adds an orbital module (satellite or spaceship) to increase the activity space, scientific experiments, etc., or adds a lunar module (lunar spacecraft) for landing on or off the lunar surface, the former Soviet Union Russia's Soyuz series and the United States "Apollo" spacecraft are typical three-cabin types. The Soyuz series of spacecraft is still in service today.

It is a vehicle that travels between Earth and space.
