Red Plague is problematic corrosion appearing on silver-plated copper conductors. An electromechanical reaction is induced between copper core and silver plating of the conductor (by means of moisture and oxygen present in the silver-copper interface). Wire affected by Red Plague is mechanically compromised, increasing the failure risk linked to severe vibration and shock conditions on space flight.

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.

During the Evaluation phase, components/technologies can be expensively characterized and margins determined. If the evaluation is successful we can then proceed with Qualification, on components produced strictly as defined in the final PID (Process Identification Document) and from a given lot (actually, the first production lot). Once qualified, the component is listed in the QPL (Qualified Part List).
