Samples on Space Exploration Essay IELTS

Sample 1: Advantages and Disadvantages of Space Exploration 

Space exploration is the detailed exploration of space, the solar system, and the universe. It is explored by robotic spacecraft and spaceflights. Earlier ‘Space Race’ was only popular between the United States and the Soviet Union. The Soviet Union achieved many milestones in its early days. It is a huge part of American history. On 20th July 1969, Neil Armstrong along with Buzz Aldrin won the space race. Yet, there are many advantages and disadvantages of space exploration. Many opine that the space program costs high, and some take it as an invention.

Advantages of Space exploration


The global society has benefited through new inventions. The additional research conducted by NASA helped to benefit society in different ways. The discoveries benefit transportation, medicine, computer management, agriculture technology, and consumer goods. The space program helped in GPS technology, breast cancer treatment, lightweight breathing systems, Teflon fiberglass, etc. 


One cannot deny the fact that space exploration generates numerous jobs globally. Spending less and making it more cost-effective is a better way to approach space exploration. Space research programs add too much to science, technology, and communication in the present unemployment scenario. And this results in a massive employment generation. 


Time to time-space exploration programs and satellite missions by NASA help unravel the undiscovered facts about our universe. Scientists better understand the nature, atmosphere of Earth, and other space bodies. These are the exploration programs that make us aware of future natural disasters and other related predictions. It also paves the path to save our almighty universe from time to time. 

Conclusion: Every coin has two sides. To sustain on Earth, one has to face the challenge and overcome it. Space exploration is a vital activity that cannot be neglected but can be improved with technology.

Disadvantages of Space exploration


Pollution is one of the alarming concerns in space exploration. Every year, many satellites are launched in space, and not all of them return. Over time, the remains of such instances become debris and float in the air. Old satellites, different types of equipment, launching pads, pieces of rockets are all adding to pollutants. Space debris pollutes space in many ways. Space exploration is not only harming the environment but also space.  


A national space exploration program costs high. Many individuals argue that space mission programs are cost-effective. It must be noted that NASA in the recent program, celebrated its 30th anniversary with an expenditure of $196.5 billion.


Space exploration is not a bed of roses. Many historical events prove the danger associated with the tragic incidents. One must focus on the incident on January 28, 1986, with the Challenger space shuttle. Within just 73 seconds, the shuttle exploded and resulted in a massive loss of life and property. 

Moreover, there are different opinions on the advantages of space exploration with more innovations and improved technologies.

Essay sample 2: The first man to walk on the moon claimed it was a step forward for humankind. However, it has made little difference in most people’s lives.

To what extent do you agree or disagree?

A greater number of people believe that space exploration has not made enough contribution to the lives of people. It has not made a sufficient impact if the expenses associated with it are justified. As per my understanding, various questions arise out of this, but if considered on an overall basis, the scientific impact is very encompassing. 

A man to the moon and expensive satellite and telescopes had no impact on the life of an average wage earner or the one without proper meals a day. A large population is still vulnerable and facing various economic challenges. Many enjoy watching the man traveling to the moon, or the NASA videos, but there is no justification for the huge amount of money that was spent over the years for space exploration. It could have made a lot of difference if these investments were directed towards employment, medicine, education, infrastructure, and culture. 

Nonetheless, the impacts are directly related to science and culture. A man on the moon was a moment of utilitarian concern. It was a powerful incident that encouraged countless lives to attain achievements. Space exploration has led to concrete and fruitful innovations. For example, new aspects of entertainment, microchip, the internet, and countless other discoveries. From small to huge, there are several discoveries, and the most important one can be staying connected throughout the globe. We are truly indebted to the funding of space exploration for all of these innovations and discoveries. 

Far from being utter waste, as some belief it to be, space exploration has been the reason for the progress of humankind. It must receive more support and advancement.
