NASA's Unusual Job
NASA is undertaking a unique mission to test the odors of materials and tools sent to the International Space Station to ensure they do not emit any unpleasant or offensive odors that could cause astronauts to feel nauseous or impact their productivity. A team of volunteers participates in this effort, including chemist George Aldrich, who has conducted over 800 odor tests over more than 40 years. Materials are evaluated on a scale from 0 to 4, with any substance exceeding a value of 2.5 being rejected. This procedure was implemented following the incident with Velcro strips that emitted strong odors when used in space, as part of safety measures tightened after the Apollo 1 disaster in 1967. These tests help protect astronauts from odors that could affect their health and safety during missions.
