Space Sniffer: NASA's E-Nose Ensures Clean Air for Crews
For long-duration space missions, whether to the International Space Station or to Mars and beyond, it's important to be able to ensure clean air for crew members to breathe. The JPL Electronic Nose (ENose) is a full-time, continuously operating event monitor designed to detect air contamination from spills and leaks in the crew habitat. It fills the long-standing gap between onboard alarms and complex analytical instruments. ENose provides rapid, early identification and quantification of atmospheric changes caused by chemical species to which it has been trained. ENose can also be used to monitor cleanup processes after a leak or a spill.
