The ST8 technologies are:

Dependable Multiprocessor: A commercial-off-the-shelf (COTS)-based computing architecture that enhances the immunity of high performance onboard processing systems to the error-causing radiation environment.

UltraFlex 175: A deployable solar array system that is a highly efficient power producer for the entire spacecraft.

SAILMAST Ultra Lightweight Boom: A technology for strong, ultra-lightweight structures that can be used to support huge, deployable solar sails and other large structures.

Thermal Loop: A miniature thermal management system for small spacecraft that tightly controls the operating temperatures of the instruments while using little power.
