Abstract

ANITA is a trace gas monitoring system for application in closed habitats such as the ISS. It has ‎been developed as part of ESA technology programs and measures quantitatively quasi on-line more ‎than 30 trace gases (including background gases) in strongly varying matrices. It is an optical ‎system, analyzing the absorption features in the infrared spectrum deriving quantitative ‎compositions of different gas molecules potentially present or even dangerous to the crew on the ‎ISS.‎

The first system, ANITA 1, has been launched and operated successfully on the ISS as a ‎demonstration facility in 2007 and 2008. ANITA is a joint ESA/NASA project. The instrument itself ‎was developed under ESA contract, with Kayser-Threde GmbH, Munich (now OHB System AG) as ‎prime and instrument developer. SINTEF, Norway, has been responsible for the complex analysis ‎software and system testing of gas analyses, while NASA took care of transport and operations. ‎

Following ANITA 1 return to ground, the mission was critically reviewed and the development of the ‎second generation instrument, ANITA 2, was initiated under ESA contract by OHB System AG and SINTEF. Following a technology program to improve sensibility and ‎reduce instabilities and sensitivity to vibrations, performed until the end of 2015, the development of ‎the second generation ANITA 2 flight instrument for the ISS has been initiated in spring 2016. The ‎system is characterized, in addition to the performance increase, by a drastic reduction in size and ‎mass, such preparing for future applications for exploration.‎

The paper will highlight the achievements of ANITA 1 with emphasis on running ANITA 2 activities ‎and further shortly address future applications. ‎
