Space exploration

Use of astronomers explore the universe as a space exploration and space technologies are defined. Space exploration in manned spaceflight and robotic space Kraft has taken.

Known as astronomical observation of objects in space is reliable history pre-dating the oldest known scientific research. Allow early 20 century development space exploration rocket fuel to spread and become a reality. Space exploration often more political competition, each country's own pace and fast get first, exploration, such as between the "competition" Soviet Union and the United States to try to push and create.

Space exploration of unusual flights has shifted from large can consider reusable hardware. Private interest in space exploration to create a more competitive with large government delegations urge has started.

Orbit insertion was made in 1957. Soviet Union, the unmanned launch Sputnik, that name at Earth orbit 150 miles. Following the success of the Soviet Union, Vangaurd 1 start was United States failure two months later. Bonding State in 1958 and started successfully orbit Explorer-Explorer 1.

In 1961, the first manned space flight Vostok 1, 27-year-old man carrying modified. Orbital spaceflight, all over the world one about 2 hours to complete. This victory, urged the world to continue space exploration. Within six months followed in the footsteps of the United States, the Soviet Union. Mercury flight Earth six times on February 20, 1962 orbit. Riding in 1963, the first female Earth 48 Vostok 6 laps did.

One of the main objectives of space exploration is the focus of life in the universe research in astrobiology. Astrobiology is mainly concentrated in the evolution of the origin and life. Commonly known as astrobiology. Biological, consider the possibility of life completely different from other life found in the past.
