Sensor for the detection and measurement of metal-corrosive and biotoxic Reactive Oxygen Species (ROS) on Moon, Mars, Enceladus, Europa

The construction of the sensor was completed at Technology Readiness Level (TRL) 4, with funding from ESA (https://activities.esa.int/4000136482).

Indicative space applications and services

Analytical and quantitative assessment of the biotoxicity of lunar and Martian dust (to exposed astronauts) through sensor measurement of the generation of carcinogenic Reactive Oxygen Species (ROS). ROS (hydrogen peroxide and superoxide free radical) are generated when lunar and Martian dust (and any type of cosmic dust) comes into contact with the fluids of the respiratory system and other organs of astronauts.

Evaluation of the corrosive and biotoxic oxidizing action of lunar and Martian dust on metallic technological materials, instruments, vehicles (rovers), base stations, astronaut suits, air filtration systems, water and food storage facilities, space greenhouses, etc., after contact/passage of the dust; for taking special protection measures.

Identification of oxidants in soil collected for the discovery of biosignatures of extraterrestrial life, and for taking special measures to chemically protect the biosignatures through the neutralization of the oxidants detected by the sensor.

Indicative terrestrial applications and services

Measurement and monitoring of the oxidative biotoxicity of airborne dust (from fires, mines, African dust, etc.), as well as that leaking through the filtration systems of airplanes, institutional and industrial laboratories, laboratory and hospital isolation chambers, etc..
