Sample IELTS Task 2 essay: is space exploration too expensive

Space exploration has always been an interesting topic for people. Some people believe that it costs too much money and that this money should be used for more important things on Earth. I partly agree with this idea, but I also think space exploration has many benefits.

On the one hand, I understand why some people think space exploration is too expensive. Sending rockets and satellites into space costs billions of dollars. At the same time, there are many serious problems on Earth, such as poverty, hunger and diseases. Many people do not have enough food or clean water, and hospitals and schools need more money. So some people think it is better to solve these problems first before spending money in space. This is a strong argument.

On the other hand, I believe that space exploration is also important and it gives us many benefits. First, it helps science and technology to develop. Many things that we use today, like GPS, weather satellites and even some medical equipment, came from space research. Second, studying space can help us to understand more about our planet and protect it. For example, satellites can show us the effects of climate change. Also, in the future, space exploration might be necessary if the Earth becomes too crowded or dangerous.

In conclusion, although I agree that space exploration is very expensive and that we should not ignore the problems on Earth, I do not fully agree that the money is wasted. In my opinion, governments should spend money on both space exploration and important problems on Earth, because both are useful for the future of humanity.

Whenever a costly space mission is announced, critics are quick to protest that such vast sums would be better spent addressing pressing problems here on Earth. While I sympathise with this concern, I disagree with the claim that space exploration is simply too expensive to justify.

The objection is, on the surface, a reasonable one. Space programmes routinely consume billions, and it is difficult to defend launching probes to distant planets when millions of people still lack clean water, adequate healthcare or basic education. Diverting even a fraction of these budgets towards poverty reduction or medical research could, the argument runs, transform countless lives in a far more immediate and tangible way. For those who prioritise urgent human need, this reasoning is understandably persuasive.

Yet such a view underestimates the profound returns that space exploration generates. Much of the technology now woven into everyday life—satellite navigation, accurate weather forecasting and numerous medical innovations—originated in or was accelerated by the demands of space research. Orbiting satellites also provide indispensable data on climate change, allowing us to monitor and respond to a threat that endangers the very populations the critics wish to protect. Looking further ahead, the long-term survival of our species may ultimately depend on understanding and eventually reaching environments beyond our increasingly fragile planet.

In conclusion, although I accept that space exploration is enormously expensive and that earthly problems must never be neglected, I cannot agree that the money is wasted. The scientific, technological and even existential benefits are too significant to abandon. The wisest course, in my view, is not to choose between the heavens and the Earth, but to fund both, recognising that progress in one often serves the other.
