The CRITICAL's Xception™ technology was selected by Jet Propulsion Laboratory (JPL) for its remote exploration and experimentation project. Xception™ was chosen for its innovative verification and validation methodology and the support of testing parallel processing and cluster computing. The Remote Exploration and Experimentation (REE) project objective is to develop low-power, scalable, fault-tolerant, high-performance computing for use in space and will demonstrate that significant onboard processing capability enables a new class of science mission.
