Debris removal technologies

Definition

Debris removal technologies are systems and methods designed to eliminate space debris, which includes defunct satellites, spent rocket stages, and other fragments orbiting Earth. These technologies aim to ensure the sustainability of space activities by mitigating the risks posed by space debris, which can lead to collisions and further debris generation. Implementing these technologies is crucial for maintaining safe operations in space and supporting a circular space economy that values the long-term use of orbital resources.

5 Must Know Facts For Your Next Test

1. Debris removal technologies include techniques like nets, harpoons, and laser systems designed to capture or deorbit space debris effectively.
2. The European Space Agency (ESA) is actively working on projects like ClearSpace-1, which aims to demonstrate active debris removal in the near future.
3. Many countries are developing national policies and international collaborations to promote the adoption of debris removal technologies.
4. The cost of removing debris is a significant concern, with estimates suggesting that it may require billions of dollars in investment over the coming decades.
5. Incorporating debris removal technologies aligns with sustainable practices in space utilization, fostering a circular economy that emphasizes recycling and resource recovery in orbit.

Review Questions
