Spacecraft: to overcome gravity

spaceship, perhaps - the most significant inventions in the history of mankind.This is a true scientific and technological breakthrough, allowing us to touch the mysteries of the universe and to understand the world outside our home planet.Human civilization throughout its history had to undergo a long and thorny path, full of mistakes and failures, the crown of which was to overcome the Earth's gravity and reaching the near-Earth space.The spacecraft has become the symbol and the top of the technological genius of earthlings.

In addition, these aircraft are a kind of "Vanity Fair" the most advanced and developed nations of the world.When creating any spacecraft used the best achievements of humanity - the most advanced design, technology and materials.Onboard equipment such devices are always the most contemporary.Often the spacecraft is a testing ground for the latest discoveries and inventions.

Not so long ago, during the "Cold War", space research has been the scene of fierce competition, intense competition, and even military-political confrontation between the two world superpowers - the United States and the Soviet Union.And it is very symbolic that the Russian people was the first conqueror of hostile human space.The significance of this event for the general history of humanity can not be overstated.

a very small period of time we are separated from the gold date marked the beginning of a new era of human development - 12 April 1961, when the legendary spacecraft "Vostok", piloted by Yuri Gagarin, stormed the near-Earth space.And though since then have visited dozens of manned space vehicles, but it was the first flight was the harbinger of a new era for mankind.

spaceship in modern interpretation - a device which is designed to deliver astronauts into space and then return them back to Earth.Therefore, the technical requirements for the spacecraft imposed much more stringent than for unmanned research aids.The main task of the designers here is to create conditions for the flight to be safe for humans.

The device, which is to a few hours or days to become the home of the astronauts must have not only a perfect system of navigation and control, and life support.All this was fully characterized by "East", which is in orbit launch vehicle of the same name.Full-launch mass of the complex is 287 tons.

constructional this device consists of two modules - descent capsule and instrument compartment.The first had a ball-faired significantly reduced congestion in passing the dense layers of the atmosphere.Sealed hull was made of high-strength aluminum alloy.Inside the descent capsule where the astronauts were to spend the entire flight, the designers have placed only the most essential life support systems and management.Everything else was in the instrument compartment.The internal volume of the descent module was 1.6 m3.Also, there was a system of thermoregulation, which contained liquid-air heat exchanger."East" was the most advanced technology of its time.It became all the advanced Soviet engineering design idea was to use an array of secret developments.

spacecraft "Soyuz", which replaced the legendary "East" and the first multi-unit - "Sunrise", was even more perfect technically.It is in all respects much superior to similar aircraft "potential enemy" (and actually quite concrete).

The ships of this type were first carried out such complex technical operations such as maneuvering in open space, manual docking, testing of new system controlled descent, was first tested the technology exchange between ships and astronauts are many other equally challenging activities.

«Soyuz», there were already three autonomous unit - device-service module, the orbital part of the traditional and the landing capsule, has made a huge contribution to space exploration and conquest of space.With all the variety and perfection of modern space technology should not forget that humanity is only the beginning of a long journey to the stars.
