Mission Statement

We develop methods, technology, and approaches to ensure the sustainable use and the safety of space infrastructure during design, operations, and disposal.


Space Debris: The Space Debris workgroup at IRAS develops and maintains the European reference model (MASTER) for the estimation of risks by high-velocity impacts from space-flight residua (so-called space debris) on satellites. The research supports the entire satellite life cycle by developing methods that
• support the mission design process with the selection of the orbit,
• support the satellite design process with knowledge of the direction of the space debris flux,
• support the operations by providing methods for the calculation of collision probabilities and the optimization of avoidance maneuvers and
• consider the re-entry of the satellite and the probabilities of trajectories that intersect populated land mass.

Exploration and Propulsion Systems: The workgroup Exploration and Propulsion Systems studies the exploration of space beyond Low Earth Orbit. Current focus is on the development of key technologies to support the construction of a future lunar base using in-situ resources and additive layer manufacturing. Furthermore, innovative propulsion concepts for cost-effective and flexible CubeSat missions are investigated. Teaching comprises but is not limited to satellite technology and operations, attitude and orbit control, spacecraft propulsion, space debris, manned systems, orbital mechanics, and the fundamentals of spaceflight.

Satellite Technology: The Satellite Technology workgroup at IRAS focusses on technology for the next generation of CubeSat to enable cost effective ADR missions in the future. Biologically inspired docking mechanisms (“gecko material”) are developed that enable material independent and repeatable docking to non-cooperative targets. Algorithms and approaches for docking to non-cooperative targets are developed and tested. Further, mission reliability aspects are considered in order to decrease the probability of satellite component failures.

Culture and Spaceflight: The Culture and Spaceflight workgroup explores the ideas of space, spaceflight, and according ethical concepts. Therefore, the integration of risk and safety in view of the ethics of spaceflight are investigated.
