Information about spacecraft; Knowledge about spaceships.

1. space craft is a kind of spacecraft that transports astronauts and cargo into space and returns safely. Spacecraft can be divided into two types: disposable and reusable. The spacecraft was put into the orbit of the Earth satellite by a launch vehicle, and then re-entered the atmosphere. In addition to the basic systems and equipment of general satellites, spacecraft also has life support system, reentry system for returning to Earth and recovery landing system.

2. The first manned spacecraft in the world was the former Soviet Oriental Spaceship/KOOC-0/,which was launched in April/KOOC-0/96/KOOC-0/. It consists of two cabins, the top of which is a sealed manned cabin, also known as the astronaut cockpit. This is a sphere with a diameter of 2.3 meters. The cabin is equipped with a life support system to ensure the life of astronauts, as well as an attitude control system to control the attitude of the spacecraft, a beacon system to measure the flight orbit of the spacecraft, a parachute recovery system for landing and an ejection seat system for emergency rescue [2]. The other cabin is the equipment cabin, which is 3. 1 m long and 2.58 m in diameter. There are braking rocket systems, batteries for supplying electric energy, gas cylinders for storing gas, nozzles and other systems in the equipment cabin to make the manned cabin leave the flight track and return to the ground. The "Oriental" spacecraft 1 has a total mass of about 4700 kg. Both it and the launch vehicle are disposable and can only perform one mission.

3.1966 On March 17, Gemini 8 astronauts made the first space docking. Soon after, because the damage system of the spacecraft suddenly failed, the astronauts had to crash and land. Astronauts Neil -A- Armstrong and David -R- Scott successfully docked with the Argonne spacecraft by manipulating their Gemini capsule on the fifth lap of the three-day mission. Half an hour later, the Gemini capsule began to spin and lose control. Then, one of the 12 small booster rockets on the spacecraft caught fire for unknown reasons. The astronauts immediately separated their plane from the argon and landed successfully in the Pacific Ocean. The mass is about 4700 kilograms.
