The Mission to Protect Satellites from Radiation

Summer 2019, NASA’s Space Environment Testbeds, or SET, will launch on its mission to study how to better protect satellites in space. SET studies the very nature of space itself — which isn’t completely empty, but brimming with radiation — and how it affects spacecraft and electronics in orbit. Energetic particles from the Sun or deep space can spark memory damage or computer upsets on spacecraft, and over time, degrade hardware. SET seeks to better understand these effects in order to improve spacecraft design, engineering, and operations, and avoid future anomalies. Spacecraft protection is a key part of NASA’s mission as the agency’s Artemis program seeks to explore the Moon and beyond.
