Space Telescope design status and operations

Abstract

The Space Telescope design concept is described in the context of the basic mission objectives. The orbiting telescope is designed to have 10 times better resolution, to see 50 times fainter stars and to have a much broader spectral range than the best existing ground observatories. The project is on schedule for launch in early 1985. Hardware assembly and test has started on the optical system, and the primary and secondary mirrors have been polished and coated. The five scientific instruments are beginning hardware assembly. The last major design review for the spacecraft has been completed, and good progress has been accomplished with the implementation of the pointing control system. The mission operations ground system has been defined and is under development. Control center design is complete and the science institute is under construction. The Space Telescope is designed to be serviceable in orbit and will be capable of return to the ground for refurbishment.
