ANITA2 is the successor system of the successful European test system ANITA1 (Analysing Interferometer for Ambient Air) which operated on ISS for 11 months in 2007 and 2008. ANITA1 delivered new and complementary information on ISS air conditions relying on optical analyses with a Fourier Transform infrared spectrometer. Advantages of the optical sensor include a high time resolution in combination with the simultaneous detection and precise quantification of the most important trace gases in the ISS atmosphere. ANITA1 data have shown new and partly surprising results on the dynamics of the crewed cabin atmosphere. ANITA2 shows improved characteristics in gas analysis sensitivity with a significant reduction in size and mass. The ANITA2 instrument in combination with sophisticated analysis SW will form a compact multi-gas air quality monitor delivering reliable data on the ISS air conditions with a time resolution of minutes for each full sets of measurements. We are also looking into other applications of ANITA2, e.g. inside closed habitats such as submarines, and are starting to investigate commercial approaches with an industrial co- funding. ANITA2 further represents a precursor system for missions e.g. to Moon and Mars under the manned exploration programme. The paper provides a status report on the instrument breadboard activities and analysis software developments and gives an outlook into future programmatics.
