Systems engineering at the Jet Propulsion Laboratory.

Work at the JPL in systems engineering is surveyed with the emphasis on practical experience with large hardware and software systems. Systems concepts in lunar and planetary projects, in the Morgantown project, and in the Urban Health Systems Task are discussed. Goal definition, problem statement, objective and criteria development, and synthesis, analysis, selection and implementation of systems are considered as successive steps in the optimization of the overall system.-

Freedom to act fast.

The history of the development program that culminated in the Explorer and Pioneer launchings is outlined. Earlier work on launching rockets, and the discovery of the Van Allen belts is discussed. The Explorer program was carried out in less than three months, and the different Explorers launched later carried widely different payloads.

Flying automated laboratories to the planets.

Review of results obtained by instrumented spacecraft in investigation of the planets, mainly Mars. It appears that Mars is a world of varying topographical structure, some of which must have been created by the same processes that sculptured the moon and by others thus far unique in the solar system. The atmosphere is too thin to shield the surface, and there are no traces of liquid water. The very large recent dust storm is discussed. Mariner 9 has revealed definite indication of probable volcanic activity on Mars in recent geologic times.-
