Space Grade Electronics or How NASA’s Juno Survives Near Jupiter

Electronic components used in spacecrafts must be built to survive the harsh space environments and function reliably in it. The US Department of Defense mandates over 100 tests to ensure reliable operation under mechanical stress, wide temperature fluctuations and intense ionizing radiation. All space grade electronic components must be individually qualified as opposed to the sample testing common in commercial or industrial applications.
