Los Alamos National Laboratory's Prometheus program developed and launched eight advanced 1.5U cubesats in November 2013.

Quality, reliable instruments for demanding space environments

The Space Electronics and Signal Processing Group (ISR-4) develops high quality, reliable instruments and systems for unattended, stable, long-term, failure-free operation in demanding environments such as high radiation, high temperature, high pressure, and caustic fluids.

An integrated engineering approach permits close interactions among the scientists, modeling and analysis personnel, and engineering and technical personnel experienced in optical, electrical, and mechanical fabrication.

ISR-4 has developed more than 600 instruments and systems from design to completion in the past 30 years.
