Iridium deorbit strategy, execution, and results

Abstract Debris remediation starts with a responsible operational posture and completes with end-of-life disposal. Iridium has just completed the largest technology refresh in space by replacing their entire fleet of LEO satellites. As part of that effort, Iridium developed and then implemented a deorbit program to ensure space was safe for future generations by meticulously ensuring each satellite being replaced was deorbited in an efficient, cooperative, and responsible manner. This paper addresses the efforts and status of the Iridium deorbit program and provides lessons learned that should be applied as best practices for future space assets.
