There is growing interest in use of Commercial-Off-The-Shelf (COTS) motors (and other components) in space. These offer low-cost and occasionally unique performance benefits compared to bespoke space motors. Recent examples of their use include Beagle II, Rosetta and numerous micro-satellite applications. However, application engineers who propose the use of COTS devices face a challenging series of materials and tribology-related issues, together with performance uncertainties. The way these challenges are met will ultimately determine whether a COTS approach to space motors and other devices will be deemed acceptable. This paper takes examples of recent programmes in which ESTL has played a role, either supporting manufacturers or space-equipment developers, in the adaptation of COTS technologies, primarily motors, to space use. The range of devices used, the scope of modifications and lubricant evaluation programmes carried out and the approach to performance evaluation are discussed.
