The Carruthers Geocorona Observatory, previously called Global Lyman-alpha Imagers of the Dynamic Exosphere (GLIDE), is a NASA mission led by the University of Illinois, which will survey ultraviolet light emitted by Earth's outermost atmospheric layer, the exosphere, and geocorona. [1] [2]
The mission name was given to honour George R. Carruthers, a pioneer American space physicist, engineer, and inventor. He is widely recognised for his groundbreaking contributions to ultraviolet astronomy. His most famous invention was the Far Ultraviolet Camera/Spectrograph, [3] a compact but powerful telescope that was placed by the astronauts of Apollo 16 on the Moon in 1972. [4]
Carruthers Geocorona Observatory was launched as a secondary payload on the SpaceX Falcon 9 launch vehicle carrying NASA's Interstellar Mapping and Acceleration Probe (IMAP) spacecraft, together with NOAA's SWFO-L1, on 24 September 2025. [5] [6] [7]
