Famous Space Explorers - Exploration of Space
Increased political tensions between Soviet Unionand the United States in the middle and late 20th century
gave the birth of the age that we today call as Space Race. From the end of World War II all up to 1975, these two countries tried to achieve supremacy
in scientific exploration using artificial satellites, orbital manned flights, and deep space missions to the moon. This competition brought with
itself (until then) unseen amounts of scientific military research, which created enormous amounts of beneficial spin off technologies that are today
used in in many other industries.
The greatest heroes from that time are without the doubt brave astronauts and cosmonauts who were the first to explore the unknown environments in
space. However, before the scientists were able to create technologies and procedures for manned flights, for more than 10 years they tested on the
animals. The importance of space animals cannot be overstated - they provided integral role in those early year of space exploration by providing the
scientist the data from then unknown space environment . Some of the most famous animals from that time were the Soviet dog Laika
(first animal who orbited the Earth in 1957), American monkeys Able and Barker (who were the first animals that
successfully returned to Earth in 1959), and chimpanzee Ham (first chimp in space, who was also trained to operate with simple
mechanical switches during his flight).
In April 12, 1961, first human went to space. After orbiting the earth for 1 hour and 48 minutes, Soviet Cosmonaut Yuri Gagarin
successfully returned to Earth in his Vostok 1 spacecraft, instantly becoming worldwide celebrity. The news of his flight spread across
the world, and only few weeks later American astronaut Alan Shepard went to the space onboard the Mercury program spacecraft called
Freedom 7. Later, he would become fifth man that walked on the moon.
When the manned space flights became reality, both America and USSR set their sights on the exploration of moon. After less than a decade of frenzied
scientific research, American space mission Apollo 11 successfully landed on the surface of the moon on July 20, 1969. In the one of the greatest
televised events in the human history, audiences across the world watched the first Moon steps of astronaut Neil Armstrong. This
mission is today remembered as one of the most important discoveries of the human kind. After the successful return of Apollo 11 (Neil Armstrong, Michael Collins, Edwin "Buzz" E. Aldrin, Jr.), NASA launched five more lunar landing missions. One of the more publicized
missions from that time was the Apollo 13 (crew James A. Lovell, John L. Swigert and Fred W. Haise), which became severely damaged
during flight and after several days of extreme hardship it safely landed back on Earth.
After the end of Apollo program in 1972, and the first cooperation between America and Soviet Union in 1975, manned exploration of space shifted focus
from the single missions to the establishment of permanent space stations. During the last 40 years, many astronauts visited the various space stations
in Earth's orbit (Skylab, Mir, and International Space Station).
The future of human exploration beyond Earth's orbit is still unknown. Newly formed space agencies from developing countries (India and China) aim to
send manned missions to the Moon in the next 15 years, while American scientist want to send human mission to explore near asteroids in the next 20
years. Hopefully, mission to Mars will not be far behind.
