Breaking the Cycle: Novel Capture Mechanisms for Active Space Debris Removal (2023)
Conference Proceeding
Taggart, A., Harris, J., Pushparaj, N., & Cappelletti, C. (2023). Breaking the Cycle: Novel Capture Mechanisms for Active Space Debris Removal.

Since the launch of Sputnik 1 in 1957, over 6000 rockets and more than 11,300 satellites have been launched into space, resulting in a high number of artificial space debris in orbit around Earth. Of this debris, there are over one million objects be... Read More about Breaking the Cycle: Novel Capture Mechanisms for Active Space Debris Removal.
