The Orion mission, an ESA/NASA cooperative project, will be the next manned vehicle beyond Low Earth Orbit (LEO) and will enable manned missions to the Moon, Mars and asteroids. The new vehicle will be propelled by a service module based on the design and experience gained with the ATV, the ISS supply spacecraft with centralized procurement of the electronic components, in which Alter Technology participated for almost 10 years.

For satellite applications where failure is not an option, electronic components need to operate constantly on demand, and have to be free of failures during the lifetime of the satellite-which can be for many years. To ensure this requirement is met, the components are put through many hours of stress testing covering all thermal.

basics in mind: three sources of radiation cause three different types of effects on a device. The three sources are the Van Allen belts, where protons and electrons are trapped around the Earth in its magnetic field lines. The second radiation source is the Sun, which continuously emits energetic particles toward the Earth. The third source of particles is galactic cosmic rays. These are made up of ions ranging from a simple proton to uranium.
