EXCALIBIR - A space experiment in orbital debris lethality

The study proposes a space experiment using extended Space Shuttle external tanks to test the impact of orbital debris. The External Tank Calibrated Impact Response test, EXCALIBIR, is a low-cost low-risk, high-payoff approach to investigating the threat to resident space objects posed by untrackable orbital debris, to provide lethality data to the kinetic energy weapons community, and to aid in the testing of space and missile interceptor technology. This experiment is a feasible use of existing assets - the external tank, observation and data collection facilities, launch facilities, and interceptor technology and tests planned for other programs.
