Meet NASA's 'master sniffer'

Apr 04, 2020 15:25 IST

Some call him 'master sniffer', others call him 'nasalnaut', meet NASA's chief Chemical Specialist. George Aldrich has been working with NASA for over 30 years and is responsible for literally 'sniffing' every object from books to gear and fabric, before it is sent to space. He helps protect astronauts from 'obnoxious' odours, and this enables them to sense dangerous smells like a chemical leak or a burn. Astronaut quarters in space do not allow a bad odour or a foul smell to escape the compound. But, it's not an easy job. To remain on the 'odour panel', Aldrich must pass an odour test every four months.
