Space at JPL
Various aspects of space R&D at JPL are reviewed and illustrated with photographs. The career and achievements of interplanetary-spacecraft designer Ronald Draper (beginning with work on Mariner 2 in 1961) are described, with emphasis on the ongoing development of the Galileo Jupiter spacecraft and the proposed Comet Rendezvous Asteroid Flyby spacecraft; the technological challenges posed by the Magellan mission to Venus (scheduled launch in 1989) are examined; and the histories of three mathematical problems with space applications are briefly recalled: the study of conic sections (applicable to orbits and trajectories), the development of formal logic (applicable to expert systems and artificial intelligence), and the restricted three-body problem of celestial mechanics.
