Space debris and its management through international cooperation has become an increasingly relevant topic in IELTS Writing Task 2 essays. Based on analysis of past exams and current global concerns, this theme has appeared multiple times in different variations, particularly in academic modules from 2019-2023. Let’s examine one of the most representative questions that has appeared in recent tests.
Question Analysis
Some people think that space debris (such as old satellites and other human-made objects) is a major problem that requires international cooperation to solve. To what extent do you agree or disagree with this view?
This question requires candidates to:
- Express their opinion on space debris as a global issue
- Discuss the necessity of international cooperation
- Support their position with relevant examples and explanations
Band 8 Sample Essay
Space debris has indeed become a critical issue that poses significant risks to space exploration and satellite operations, and I strongly agree that international collaboration is essential for addressing this growing problem effectively.
The severity of space debris issue necessitates global cooperation for several compelling reasons. Firstly, space debris knows no national boundaries – defunct satellites and rocket parts orbit Earth indiscriminately, potentially threatening spacecraft and satellites from all nations. For example, even a small piece of debris traveling at orbital velocities can severely damage or destroy functional satellites that provide crucial services like weather forecasting and telecommunications. Furthermore, the astronomical cost and technical complexity of debris removal operations make it impractical for any single nation to tackle this challenge alone.
International cooperation can provide multiple advantages in managing space debris. Collaborative efforts enable the sharing of technical expertise, resources, and costs among spacefaring nations. The International Space Station’s debris monitoring system, which involves multiple space agencies working together, demonstrates how joint initiatives can enhance our capability to track and avoid space debris. Additionally, unified international regulations and guidelines for satellite deployment and end-of-life disposal can help prevent the creation of new debris.
Looking ahead, only through sustained international cooperation can we hope to implement ambitious solutions such as debris removal missions and space traffic management systems. While individual countries might have different space capabilities and interests, the shared goal of maintaining a safe and sustainable space environment should motivate collective action.
Band 6.5 Sample Essay
Space debris is becoming a bigger problem every year, and I agree that countries need to work together to solve it.
The main reason why international cooperation is needed is because space debris affects everyone. When old satellites break up in space, the pieces can damage working satellites from any country. For example, in 2009, two satellites crashed and created thousands of pieces of debris that are still dangerous today. Also, cleaning up space junk is very expensive and difficult, so one country cannot do it alone.
Working together has many benefits. Countries can share their technology and split the costs of cleaning up space. The International Space Station already shows how countries can work together in space. Also, if all countries follow the same rules about launching satellites, we can stop making more space junk.
However, there are some challenges to working together. Different countries have different space programs and might not want to share their technology. Some countries might not want to spend money on cleaning up space debris when they have other problems to solve.
Even with these problems, I think international cooperation is the only way to solve the space debris problem. If countries don’t work together, the problem will just get worse and eventually affect everyone on Earth.
