Space Astronomy: Present Reality and Future Prospects

Results of the Orbiting Astronomical Observatory (OAO) observations of comets, novae, and galaxies are described as benefits from maintaining a continuous observing capability in space. The increased capabilities of the next two OAOs are cited as providing the basis for future astronomy missions. A practical and economical approach to space astronomy is developed on the basis of commonalty at the subsystem level. This approach, space telescopes for astronomical research, called Project STAR, provides the capability of flying optical telescopes with diameters of up to 120 inches, as well as major solar and X-ray instruments. The potential of resupply missions based on the space shuttle concept is developed.
