In 21th century, the space within solar system has never been so crowded with probes, satellites and instruments travelling to range of destination.
In the 1950s, there was a recognition's basic philosophy, which is said that anyone country which first did establish the permanent universe space station successfully, it sooner or later can control the entire Earth. Under this kind of background, more and more countries gather theirs horizon on this unknown area-The universe. The space travel started after the World War II.
Exploring Solar System
Model of Sputnik I
Sputnik & Vostok I & First man to the space
After World War II, the relation between USSR and USA were strained , keen competition in military, science and economy had boosted overall national power of both of the countries.
Until 1957, The Soviet Union developed a space exploration program, called “Sputnik Program”. The Sputnik I was the first human made satellite that launched into the space. It used R-7 rocket as launching system, which designed initially to carry nuclear warhead. After orbiting the earth for 57days, Sputnik I was disappeared in the atmosphere, but it was beginning of the space travel and it brings a lot of impact to the world. A series of sputniks launched to the space followed “sputnik I”, and they succeeded in carrying living objects and scientific instrument to the space, In 1961, Soviet astronomer Yury Alekseyevich Gagarin took Vostok I entered to the space and became the first human who travelled the outer space of the earth.

NASA & Saturn Rockets & First man to the moon
Sputnik and Vostok Program shocked Americans and accelerated development in spacecraft and astronomy. American government established NASA (National Aeronautics and Space Administration) and planed a program that lands the first crew on the moon. From both the Mercury-Gemini- Apollo program and the Lunar obiter missions, Americans had got a series of information about the moon and it became a base of the human crew moon landing. In 1969, Apollo 11 landed on the surface of the moon and Neil Armstrong , Edwin Aldrin and Michael Collins put up the American flag on the Moon. It was the one of the most significant moments in the history of the 20th century and has permitted a decisive qualitative leap not only in the understanding of our satellite but also in the development of space technologies.
Saturn V first stage thrust performance during Apollo 15 launch.
7,823,000 pounds-force (34.80 MN) liftoff thrust.
| Apollo program succeeded six times in landing on the moon and the last spacecraft was Apollo 17(1972).They could succeed because they have powerful launch system which commonly known as Saturn Rocket. All of Apollo series had used Saturn rockets and it also used in world first spaceship called skylap launch system. Saturn rockets have enormous thrust and have at least 118t payload to launch to the earth orbit.
Model of Voyager I
Voyager I and II & Viking program
The voyager programme (National Aeronautics and Space Administration, 1977): there were two probes voyager 1 and voyager2 designed to collect data on Jupiter and Saturn, and their satellites. The voyager I was travelled around the Jupiter and Saturn and collected data and images, while the voyager 2 was redirected to other giant planets, such as Uranus and Neptune. The information that we know about these planets are basically contributed by voyager 1 and voyager2.
Surface of the Mars
After American won the race to the Moon, both of countries were interested in Mars. NASA ran another programme to research Mars. The Viking programme consists of two space crafts, which are Viking 1 and Viking 2, each made up of an orbiting...
