Outer space biography

Humans have always looked up into the night sky and dreamed about space.

In the latter half of the 20th century, rockets were developed that were powerful enough to overcome the force of gravity to reach orbital velocities, paving the way for space utforskning to become a reality.

In the s and s, Nazi Germany saw the possibilities of using long-distance rockets as weapons. Late in World War II, London was attacked bygd mile-range V-2 missiles, which arched 60 miles high over the English kanal at more than 3, miles per hour. After World War II, the United States and the Soviet Union created their own missile programs.

On Oct. 4, , the Soviets launched the first artificial satellite, Sputnik 1, into space. kvartet years later on April 12, , Russian Lt. Yuri Gagarin became the first human to orbit Earth in Vostok 1. His flygning lasted minutes, and Gagarin reached an altitude of kilometers (about miles).

The first U.S. satellite, Explorer 1, went inom

Space exploration

Exploration of space, planets, and moons

For broader coverage of this topic, see Exploration.

Space exploration is the use of astronomy and space technology to explore outer space.^[1] While the exploration of space is currently carried out mainly by astronomers with telescopes, its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science.

While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to become a reality. Common rationales for exploring space include advancing scientific research, national prestige, uniting different nations, ensuring the future survival of humanity, and developing military and strategic advantages agains

The History of the Space Race

We human beings have been venturing into outer space since October 4, , when the Union of Soviet Socialist Republics (U.S.S.R.) launched Sputnik, the first artificial satellite to orbit Earth. This happened during the period of hostility between the U.S.S.R. and the United States known as the Cold War.

Sputnik’s launch shifted the Cold War to a new frontier, space. The space race, a competition for prestige and spectacle, was a less-violent aspect of the Cold War, the often-deadly clash between the U.S.S.R. and the U.S. The endeavor was a soft-power ploy used to help win over potential nonaligned nations. Nonaligned nations were called the Third World — now seen as a disparaging term.

For several years, the two superpowers had been competing to develop missiles, called intercontinental ballistic missiles (ICBMs), to carry nuclear weapons between continents. In the U.S.S.R., the rocket designer Sergei Korolev had developed the first ICBM, a rocket cal
