An international research team, led by scientists from NASA’s Jet Propulsion Laboratory (JPL), the University of Plymouth in the UK, and the University of Texas in the US, has urged the United Nations to take action against the growing issue of space debris. The initiative calls for the protection of Earth’s orbit to be included in the United Nations’ Sustainable Development Goals (SDGs). Currently, this issue is recognized as an escalating global threat. So, what’s next?
NASA and Scientists Ask the UN for Help with Space Debris
In the past 15 years, the number of satellites in Earth’s orbit has increased tenfold, from fewer than 1,000 to over 10,000 today, and the number continues to grow rapidly. Satellites that have completed their missions turn into space debris, increasing the risk of collisions with other objects. This situation amplifies the threat of the Kessler Syndrome—“a chain-reaction collision effect” that continuously generates new debris.
Recent reports reveal that researchers are emphasizing the need for the UN to incorporate a space preservation goal into its existing SDGs. This proposed goal would aim to foster international cooperation to ensure the safety and sustainability of outer space. The scientists compare this approach to SDG 14, which focuses on protecting marine ecosystems and addressing issues like oceanic plastic pollution. They suggest adopting a similar strategy for space debris.

Space debris doesn’t just threaten satellites and spacecraft in orbit; it also has atmospheric consequences. For instance, the reentry of satellites into the atmosphere releases chemicals like aluminum oxide, which can harm the ozone layer and alter Earth’s capacity to reflect sunlight. Experts warn that this could have severe negative impacts on climate change.
Experts argue that tackling this issue requires global collaboration. Melissa Quinn emphasized that space is no longer an unlimited resource, as it is under increasing pressure from human activities. She called on the international community to address this challenge together.
