Background OF TECHN Why is Software Engineering Hard? “Curse of flexibility \And they looked upon the software and saw that it was good. But they just had to add one other feature ... No physical constraints

Overview Spacecraft data processing requires microcomputers and interfaces that are functionally similar to desktop systems However, space systems require: - Low power, volume, and mass High reliability and fault tolerance
