CFESat (Cibola Flight Experiment Satellite) was a satellite that examined radio spectra for ionospheric and lightning studies, using field-programmable gate arrays (FPGAs). As well as science observation, the mission aimed to demonstrate the use of reconfigurable FPGAs to work in the radiation environment of low Earth orbit.[1][2]
The eight satellite payloads were built by Los Alamos National Laboratory, and the bus was built by Surrey Satellite Technology Ltd.[1][2] CFESat was the fourth experimental satellite project conducted between the National Nuclear Security Administration and NA-22 (the United States Department of Energy's Office of Research and Development), following up on previous space validation experiments performed on the ALEXIS and FORTE satellites.[3]
CFESat was launched on an Atlas V rocket from Cape Canaveral on 8 March 2007, alongside Orbital Express, MidSTAR-1 and FalconSAT-3.[4]
CFESat reentered the atmosphere on 12 November 2022, after fifteen years in orbit.[5]
