Progress in ANITA2, the Upcoming High Performance ISS Air Monitor for Continuous In-Orbit Operation
Following the successful European precursor mission ANITA1 (Analysing Interferometer for Ambient Air) operating on ISS for 11 months in 2007 and 2008, the next generation system ANITA2 is in the design and breadboarding phase. The ANITA1 data have delivered new and partly surprising results on the dynamics of the crewed cabin atmosphere showing the advantages of an optical sensor with high time resolution. The successor instrument ANITA2 is developed to give a system with significant improvements in sensitivity and instrument characteristics. ANITA2 will be calibrated to detect and quantify simultaneously and quasi on-line more than 30 of the most important trace gases in the cabin atmosphere with automatic operation for three to five years on ISS. ANITA2 will be a maintenance-free, reliable, and compact multi-gas air quality monitor. ANITA2 is like ANITA1 suggested to be an ESA-NASA cooperative programme. It further represents a precursor system for missions e.g. to the Moon and Mars under the manned exploration programme. The following ANITA3 system will be a high performance, maintenance-free measurement unit approaching the size of a shoe box. The paper will report on the newly started ANITA2 development of an instrument breadboard and analysis software pre-developments giving an outlook into the future programmatics. The work described is performed under contract of the European Space Agency ESA.
