Space debris, or the accumulation of discarded human-made objects in Earth’s orbit, has become a growing concern in recent years. As technology continues to advance, so does our ability to reach and explore the outer reaches of space. But as we venture further into the unknown, we must also consider the impact of our actions and the potential dangers they pose to the environment and those who explore it.

History of Space Debris

The space debris problem began in the late 1950s and early 1960s when the first satellites were launched into orbit. Over the years, more and more satellites were launched, along with discarded rocket stages, dead satellites, and other objects.

Today, there are an estimated 130 million pieces of space debris in orbit, some as small as a millimeter and others as large as a bus. This accumulation of debris has the potential to cause serious damage to active satellites, the International Space Station, and even to the astronauts who call it home.

International Efforts to Tackle the Problem

Since the inception of the space debris problem, various international organizations and governments have been working to address the issue. One of the first organizations to tackle the problem was the Inter-Agency Space Debris Coordination Committee (IADC), which was established in 1993. The IADC is made up of 14 space agencies from around the world and is responsible for coordinating efforts to mitigate the risks associated with space debris.

In 2007, the United Nations General Assembly passed the first-ever international treaty on space debris, known as the “International Treaty on Commercial Space Cooperation“. This treaty established guidelines for the responsible use of space, including measures to reduce the creation of new debris and the removal of existing debris. The treaty also established the International Space Safety Institute (ISSI), which serves as a central repository for data on space debris and as a forum for international cooperation on space safety issues.

One of the key players in the international effort to tackle space debris is the European Space Agency (ESA). In 2013, ESA launched its Clean Space Initiative, which aims to reduce the environmental impact of European space activities, including space debris. The initiative includes the development of new technologies and approaches to minimize the amount of space debris created and the removal of existing debris.

In addition to the work of international organizations, a number of private companies, such as SpaceX, are also working to address the space debris problem. In 2018, SpaceX launched its first mission to remove an inactive satellite from orbit, setting the stage for further efforts to clean up space.

Recent Advances and Innovations

In recent years, there have been several exciting advances in space debris detection and mitigation technology. One of the most promising of these technologies is the use of robotics and artificial intelligence to remove space debris. For example, in 2019, the European Space Agency launched a mission to test a new robotic technology that can capture and remove debris from orbit.

Another innovation in space debris mitigation technology is the use of a net or a harpoon to capture and remove debris. In 2020, a consortium of European companies and organizations launched a mission to demonstrate the feasibility of capturing space debris with a harpoon. The mission was a success, and it is hoped that this technology will become an important tool in the effort to clean up space.


The growing issue of space debris is a pressing concern for the global community. Through international collaboration and innovative technology, significant progress is being made to mitigate the dangers posed by this problem. Despite the challenges, the inspiring efforts underway to tackle space debris demonstrate the determination of humanity to maintain a safe and sustainable future in space.
