ESA developing radiation-hardened computer for Hera mission

Being developed under the oversight of QinetiQ Space in Belgium, the Hera spacecraft’s computer is designed to operate hundreds of millions of miles from Earth with a minimum of supervision from mission control, in a hostile radiation environment. To achieve this requires a hardened architecture, a careful choice of components, and software that can work around the damage that is certain to occur due to charged particles cascading through the shielding – these could corrupt the computer’s memory, or cause a series of short circuits in the microcircuitry.
