Brief profiles on the experts of the ESA Space Debris Office, located at ESOC, the European Space Operations Centre, Darmstadt, Germany.
 | | | H. Klinkrad | Heiner Klinkrad Dr Heiner Klinkrad is ESA's senior space debris expert and is head of ESOC's Space Debris Office.
He joined ESA in 1980 and has worked in the area of debris research since 1988. He coordinates ESA's space debris research activities and represents the Agency at several international space debris forums, including the IADC (Inter-Agency Debris Coordination Committee). His main technical interest is with conjunction event predictions, re-entry risk assessments, debris environment models and space object databases. Dr Klinkrad has been chair (and previously co-chair) of the programme committees of the European Conferences on Space Debris and has been the main scientific organiser for space debris sessions at COSPAR congresses since 2004. He is author of a textbook on "Space Debris – Models and Risk Analysis."  | | | Gerhard Drolshagen | Gerhard Drolshagen Dr Gerhard Drolshagen works in the Space Environments & Effects Section of ESA's Directorate of Technical & Quality Management at ESA/ESTEC.
He is mainly involved in space debris and meteoroid activities related to space segment design, including: impact risk assessments, protective shielding for spacecraft, in-situ impact detectors, post-flight impact analysis, impact databases and the development of damage assessment tools. Michel Lambert Michel Lambert has been involved in space debris activities at ESTEC since 1986. His work has been devoted in particular to the exploration of possible protection concepts for the European Columbus module of the International Space Station.
His technological work has focused on three topics: material and configuration characterisation under hypervelocity impacts, the exploration of experimental techniques and the validation of numerical simulation codes.  | | | Rüdiger Jehn | Rüdiger Jehn Dr Rüdiger Jehn joined the space debris team in 1989 as a space debris analyst. He manages several space debris-related contracts dealing with space debris observation via radar and optical instruments.
He has been monitoring the trackable space object population near the geostationary ring for more than a decade, and is the main author of an internationally circulated annual report, "Classification of geostationary objects." He is also involved in analyses of the effectiveness of debris mitigation measures in various orbital regimes.  | | | Holger Krag | Holger Krag Dr Holger Krag has been working in the field of space debris environment modelling and on the simulation of debris sensor systems since 1998, and he joined ESA's Space Debris Office in 2006.
He is responsible for the space debris operational infrastructure, including analysis software for predicting and assessing in-orbit conjunctions and re-entry events, hardware and software aspects of the ESA space debris telescope and several operational services related to space debris.
He is also in charge of a number of development and maintenance contracts related to the ESA MASTER model, ESA telescope camera and SSA design studies. Last update: 12 January 2012 | |
