About ESA's space debris team
Prof. Klinkrad is ESA’s senior advisor on space debris and is head of ESA’s Space Debris Office. He joined ESA in 1980 and has worked on debris research since 1988. He coordinates ESA’s space debris research activities and represents the Agency at several international space debris forums, including IADC and UNCOPUOS. His main technical interest is with orbit mechanics, conjunction event and re-entry risk assessments, debris environment models and space object databases. Prof. Klinkrad chairs the programme committees of the European Conferences on Space Debris and has co-organised space debris sessions at COSPAR and IAC congresses. He is author of a standard university-level space debris textbook and is an adjoint professor at the Technical University of Braunschweig, Germany.
Dr Tim Flohrer joined ESA’s Space Debris Office in 2007 and has been working on space surveillance and space debris topics for more than 10 years. Today, his main tasks include operational collision avoidance activities for ESA missions, re-entry assessments and maintaining the Office’s database infrastructure. His main area of interest lies in the development and validation of ground- and space-based observation techniques, in particular using optical sensor systems, also in context with Space Situational Awareness applications.
Dr Holger Krag has been working on space debris environment modelling and the simulation of debris sensor systems since 1998. He joined ESA’s Space Debris Office in 2006. He operates the system for the prediction and assessment of in-orbit conjunctions and re-entry events and he supports the implementation of mitigation measures for several missions. He is also in charge of a number of development and maintenance contracts related to ESA’s debris software packages, such as MASTER and DRAMA, and of studies on environment evolution and debris observation. He represents the team on matters related to active space object removal.
Dr Klaus Merz joined ESA in 2002 and joined the Space Debris Office in 2010. He works on space object trajectories covering various areas such as orbit prediction (spanning short- to long-term), orbit control and operational orbit determination. His main tasks include operational conjunction analysis and collision avoidance activities for ESA and third-party missions. This includes Launch and Early Orbit Phase support, upgrades of the supporting analysis software, and support to standardisation at an international level. He is also responsible for studies of potential disposal orbits for ESA missions.
