The increasing frequency of satellite launches and space debris is becoming a threat to the Earth.
What are the main causes?
What measures can be taken to address this?
Nowadays, the increasing number of satellite launches and the accumulation of space debris have raised serious concerns about their potential threats to the Earth. However, what causes this problem and how it can be effectively addressed remain controversial issues. My view is that the rapid expansion of the space industry and the lack of strict international regulations are the major causes, but with collective efforts, this problem can be managed.
First, it is obvious that the booming demand for satellite services has led to the frequent launches. This is because not only are satellites essential for communication, navigation, and scientific research, but also private companies have joined the space race, seeking commercial profits. As a result, the space around Earth, particularly low Earth orbit, has become increasingly crowded with operational satellites and leftover fragments, such as broken parts and inactive spacecraft.
Moreover, actually, the insufficient international cooperation and lack of binding laws have worsened the situation. For example, there are currently few enforceable rules requiring satellite operators to remove their devices after the end of their missions. Without proper guidelines and penalties, many old satellites and debris are simply left to float in orbit, posing collision risks that can create even more debris. If countries and organisations continue to act independently without a unified approach, the space environment will only deteriorate further.
That is not to say that the issue of space debris is beyond control. Several effective measures can be adopted. For instance, governments and international bodies can establish stricter regulations, requiring satellite operators to plan for end-of-life disposal, such as de-orbiting or moving to graveyard orbits. Furthermore, technological innovations, like debris removal missions using nets, lasers, or robotic arms, can be developed and supported. Only by taking joint actions at a global level can we ensure a safer and cleaner space for future generations.
In sum, the main reasons behind the rise in space debris are the commercialisation of space activities and the absence of strict global regulations. Nevertheless, by introducing effective laws and advancing clean-up technologies, we can prevent this problem from threatening the Earth. Only through international collaboration can we protect the outer space environment while enjoying the benefits of satellite technology.
