MUCA mobil unit for contamination analysis - new concept for Assay handling
Abstract
Projects such as EXOMARS 2020, Juice or Mars Sample Return and other further planned project with dedicated planetary protection constraints lead to new challenges due to simultaneously achieving extreme levels of particulate, molecular and biological cleanliness levels. Beside the difficult task to translate the performance goals into requirements on prime and subco level the presentation shall focus on the topic of verification. The heritage of OHB is based on the direct contribution, such as the High Resolution Camera, the Sample Processing and Distribution System (SPDS), the optical harness and the Analytical Laboratory Drawer (ALD) developments for the ExoMars2020 mission. The contributions cover the full range of cleanliness deliverable status from visible clean components to be finally cleaned by the Customer up to components clean integrated in the ultra clean zone. The aspect of coordination of subcontractors across europa and cooperation with US subcontractors in combination with the regulations of assay taking and documentation lead to the development of the MUCA concept.MUCA shall become a mobile, flexible to use high end laboratory system to be used for at least the following aspects: Temporary operation of assay task on subcontractor side, education for planetrary protection training and hands on experience, standardisation between laboratories, on side control at test houses and launch side, lessons learned distribution... Results of a feasibility study covering aspects like necessary equipment, logistic, cleanliness levels and monitoring have been collected and shall be presented. A schedule to set MUCA in operation for national and international missions with high demands on contamination control will be shown. We believe that MUCA could provide a positive impact on standardisation between different agencies, contries and subcontractor. Key questions of limited duration between sample taking and analysis plus data handling of large assay numbers is covered. Overall MUCA sahll lead to schedule, risk and cost reductions. The MUCA concept was created within a cooperation between OHB and the expert from the IPA Fraunhofer institut. The combination of space and non-space application heritage lead to new interesting aspects.The concept and its applications shall be presented and we are looking for an open discussion.
