About

Pablo Colmenarejo is a leading expert in space robotics and active debris removal (ADR), whose work is critical to the future of sustainable space operations. His research focuses on the guidance, navigation, and control (GNC) of robotic spacecraft designed for on-orbit servicing, including satellite repair, refueling, and the capture of defunct space debris. Colmenarejo’s major contributions lie in developing and validating robust control strategies for the complex choreography between a chaser satellite and its robotic manipulator during autonomous rendezvous and grasping maneuvers. His foundational 2018 paper on microgravity simulation validation (12 citations) established key methodologies for testing these high-risk operations on Earth. He further advanced the field through the COMRADE project, where he compared H-infinity and nonlinear Lyapunov-based control approaches to ensure stable, combined control of spacecraft and arm during debris removal and refueling missions. His work directly addresses the immense challenge of autonomously grappling uncooperative, tumbling objects in orbit—a critical capability for mitigating the growing space debris problem. With a career dedicated to turning the economically vital concept of on-orbit servicing into a reliable reality, Colmenarejo’s research is foundational for the next generation of autonomous space robotics.
