Deployable Composites for Satellite Deorbitation

Space debris is a growing threat to operational satellites and future space missions. One passive deorbitation strategy uses electromagnetic drag sails: large, lightweight deployable panels that interact with Earth’s magnetic field to produce a braking force, gradually lowering a satellite’s orbit until atmospheric reentry.

This project develops deployable composite panels optimized for this application. The key challenges are achieving the extreme mass efficiency required (panels must be very light to be practical as a secondary payload), ensuring reliable deployment from a compact stowed configuration, and maintaining sufficient electromagnetic conductivity and structural integrity throughout the deorbitation sequence.

Research published in 2025 presents a composite panel architecture and deployment mechanism validated through ground testing, with analysis of the electromagnetic interaction performance expected in low Earth orbit conditions.
