Stratospheric Photochemistry, Aerosols and Dynamics Expedition (SPADE)

Stratospheric Photochemistry, Aerosols and Dynamics Expedition (SPADE) Logo

The NASA High Speed Research Program (HSRP) is charged with assessing by 1995 the environmental impact of a projected fleet of high-speed civil transports (HSCT's, a commercial supersonic aircraft fleet). The Atmospheric Effects of Stratospheric Aircraft Program (AESA) was established within the HSRP to prepare an assessment of the chemical perturbations to the atmosphere caused by HSCT emissions.
