The proliferation of ride-share rocket launches and decrease in the overall cost of sending payloads to space due to recent successes in the private space industry has made small satellite systems a cost effective and time-efficient method to put research vehicles in space. The University of Alabama in Huntsville’s Center for Cybersecurity Research and Education (CCRE) has been funded by the U.S. Army Space and Missile Defense Command (SMDC) over the last several years to investigate the overall cybersecurity posture of small satellite systems. Numerous iterations of student teams led by CCRE and SMDC staff members have managed to accomplish notable research milestones. This talk is meant to inform the next generation in aerospace cybersecurity by discussing our major research milestones, relevant findings, lessons learned, and areas of concern relating to the overall cybersecurity posture of small satellite systems.
