Space Debris


The aim of the Space Debris workgroup is to support sustainable space flight. Basis for all activities is the knowledge and application of general and higher orbital mechanics. The main research consists of the orbital dynamics of all objects on Earth orbits (space debris), orbit survey and orbit prediction, especially for light satellites and the re-entry of hazardous objects. The Space Debris workgroup belongs to the leading experts in the field of Space Debris modelling. These research activities are applied in several domains:
Space Debris Modelling
-    Modelling of individual sources: explosion- and collision fragments, solid  rocket motor dust and slag, NaK coolant droplets, ejecta, paint and MLI degradation, micrometeoroids
-    Simulation of fragmentation events: estimation and prediction of time-invariant and spatial distribution of objects on arbitrary orbits
Space Debris long term analyses
-    Projecting the evolution of the future space debris environment
-    Analyses of Space Debris mitigation techniques on the future environment
-    Analyses of cascade effects due to collisions
-    Impact of large constellations and small satellites on the long-term evolution
Space Debris cost-benefit-analysis
-    Safety precautions for active satellites
-    Economics of debris mitigation techniques
Space Debris risk analyses
-    Particle flux analyses on satellite surfaces
-    Analyses of penetration- and failure-probability
Space Debris observation
-    Design of optical sensors and radars (monostatic, bistatic, phased array)
-    Scheduling of measurement campaigns
Space Surveillance and Tracking System simulation
-    Simulation of observation campaigns
-    Performance analysis of single sensors and sensor networks
-    Simulating cataloguing of space debris objects with different orbit determination methods, sensors, etc.
Space technology education:
-    Lectures, exercises, laboratories: Fundamentals of space technology, perturbated orbits, satellite techniques, space debris, manned spaceflight, mentoring and supervision of graduating students (MA/BA theses)
The activities are accompanied by re-entry predictions of hazardous objects and simulating observations of Near Earth Objects.
Members of the Space Debris workgroup are delegates for the German Aerospace Center to the Inter Agency Space Debris Coordination Committee (IADC).
