Space Exploration: Venture Into The Unknown


Introduction To Space Exploration

Space exploration refers to a physical probe into the outer space. This exploration is carried out by both humans as well as robotic spacecraft.

The concept of such exploration became a practical probability in the early 20th century due to the development of large rocket engines that were fueled by liquid. The underlying rationale behind the exploration was to advance scientific research and to unite different nations towards achieving a common goal.

Brief History

The dawn of such exploration was driven by competition between the two superpowers- USA and USSR. USSR’s Sputnik-1 was the first artificial object that orbited the Earth in 1957.  American Apollo 11 craft made the first landing on the moon in 1969. Yuri Gagarin from the Soviet Union was the first man to go to space. Also, USSR’s Aleksei Leonov was the first man to complete a spacewalk.

Motivation For Space Exploration

Till the latter half of the 20th century, only the national governments could afford to bear the high costs associated with launching people to space. This meant that broad interests were served by space exploration. Various space programs initiated by governments have increased our knowledge. These programs also serve as symbols of national power and prestige. Towards the beginning of the 21st century, entrepreneurs started believing in the possibility of commercial potential in space. This led to the growth of privately funded travel.

Significant Milestones Achieved

Since 1957, satellites that orbit the earth and robotic spacecraft have gathered valuable information about various bodies in the solar system, including the Sun. Robotic spacecraft have accomplished landing on moon and mars. They have also been in close proximity of all major planets. They have also traveled into the inner solar system. Scientists use Space-derived information to improve the understanding of our origin. It has also helped in understanding the evolution of galaxies, planets and other celestial bodies.

Some Pioneers Of Space

Some recognized pioneers of the first generation included Oberth, Tsiolkovsky, and Goddard. Apart from these, some other scientists contributed in the early decades of the 20th century. Famous names include Frenchman Robert Esnault -Pelterie. He had worked on theoretical aspects of spaceflight in 1907 and has several books to his name on this topic. Austrian scientist Eugen Sanger made his contribution in the field of rocket engines. In the late 1920s, he had proposed the idea of developing a rocket plane. This plane had the capability to reach a speed of more than 10,000 km per hour.

Thus, to be able to look after our planet wisely, it is important to know its distinguishing factors. Such factors include knowledge about its atmosphere, geology, life, and oceans. The investigations conducted by scientists in outer space help in understanding our planet better.

Astronomy also helps in creating a vibrant image of our position in space-time. It also helps in answering questions related to our existence. The results of such missions conducted to enhance the power of the imagination of humans. This inspires students to pursue careers in science and result in creating an interest in this field for the general mass.
