👉 Shuttle fumes refer to the harmful gases and particles released during space shuttle launches, primarily from the combustion of solid rocket boosters (SRBs) and liquid hydrogen peroxide used in the main engines. These emissions contain toxic substances like hydrogen chloride, hydrogen fluoride, and various heavy metals, which can pose significant health risks to both astronauts and ground personnel. The intense heat and pressure during launch cause these chemicals to vaporize, creating a plume of pollutants that can travel long distances. While modern shuttle designs and operational procedures have reduced some emissions, shuttle fumes remain a critical environmental and safety concern, necessitating strict regulations and monitoring to protect air quality and human health.
