The accumulation of space debris poses a significant threat to operational satellites and space missions. With thousands of defunct satellites and fragments orbiting Earth, the risk of collisions increases, which could potentially lead to a cascade of destructive events known as the Kessler Syndrome. Efforts are being made to mitigate this issue through tracking, removal technologies, and international cooperation.

Key insights

  • 1

    The Scale of the Problem: There are currently over 27,000 pieces of space debris being tracked by the Department of Defense’s global Space Surveillance Network (SSN) sensors. This number does not include the millions of smaller pieces that are too small to be tracked but large enough to threaten human spaceflight and robotic missions.

    Potential Solutions: Various methods are being explored to address the space debris problem, including the development of debris removal technologies such as nets, harpoons, and robotic arms. Additionally, improved satellite design and end-of-life disposal plans are crucial for sustainable space operations.
