Technology Demonstration

This chapter describes the development, operation, and experimental results of the Third Generation JPL Electronic Nose (ENose), which operated on board the International Space Station (ISS) as a technology demonstration for seven months from 2008-2009. The JPL ENose is an array of chemiresistive sensors designed to monitor the environment for the sudden release of targeted chemical species, such as leaks or spills. The Third Generation JPL ENose was designed to detect, identify, and quantify eleven chemical species, three inorganic, ammonia, mercury, and sulfur dioxide, and eight organic compounds, which represent common classes of organic compounds such as alcohols, aromatics, and halocarbons. Chemical species were quantified at or below their 24 hour Spacecraft Maximum Allowable Concentrations (SMAC), generally in the parts-per-million range; some targeted species were detected in the parts-per-billion range. Analysis of third generation JPL ENose monitoring data on ISS show the short term presence of low concentrations of alcohols, octafluoropropane, and formaldehyde as well as frequent short term unknown events. Repeated unknown events were identified post-flight as sulfur hexafluoride.

AbstractWe report on the detection of microorganisms onboard the International Space Station (ISS) using an electronic nose we named the E-Nose. The E-Nose, containing an array of ten different metal oxide gas sensors, was trained on Earth to detect the four most abundant microorganisms that are known to exist onboard the ISS. To assess its performance in space, the E-Nose was brought to the ISS and three measurement campaigns were carried out in three different locations inside the ISS during a 5-month mission. At the end of this mission, all investigated locations were wiped with swabs, and the swabs and odor sensor signal data were sent back to Earth for an in-depth analysis in earthbound laboratories. The in-space measurements were compared with an odor database containing four organisms, but a consensus odor could not be identified. Microbiological results could not provide clues to the smell that was measured. The yeast Rhodotorula mucilaginosa was identified in the literature as the most probable candidate for the unknown odor. Further investigations showed that the smell of Rhodotorula mucilaginosa matches very well with the data obtained inside the ISS. Finally, Rhodotorula mucilaginosa DNA was identified in swabs taken from the sleeping cabin of the astronaut, which confirms the assumption that the yeast Rhodotorula mucilaginosa was actually measured in space by the E-Nose.
