kgeiger writes "The Sprite project is testing the feasibility of chip-sized spacecraft. 'Rather than hand building one-of-a-kind spacecraft, we envision constructing spacecraft on wafers in much the same way that common integrated circuits are made today. During fabrication, solar cells and other components would be incorporated with microelectromechanical systems techniques. Instead of exhaustively testing each part, as is done with current spacecraft, engineers will be able to monitor Sprite quality in a less labor-intensive fashion by using statistical process control, testing a few chips from each batch to make sure they meet specifications.' The project's goal is to deploy true 'smart dust,' comprised of 5- to 50-mg single-sensor spacecraft capable of forming deep-space sensor arrays."
