Analysing Interferometer for Ambient Air (ANITA) is a trace gas monitoring system for the International Space Station (ISS).
Monitoring air quality on ISS helps provide adequate life support for the crew.
Compared to ANITA-1 it has a significantly increased (~factor 4) Signal to Noise Ratio allowing lower detection limits.
[3][4] ANITA-2 was installed in an Express Rack inside the Destiny Lab by Matthias Maurer January 5, 2022.
[5] ANITA-2 is running nearly continuously on board the ISS since March 2022 and is monitoring the gas environment.
