Space telescope

Abstract

This paper describes the Space Telescope, a program of the National Aeronautics and Space Administration (NASA). The Space Telescope is the largest and most powerful optical and ultraviolet astronomical observatory to be operated in space. Through the remote eyes of this telescope, astronomers will look further into space and time to produce data including imagery of unequaled quality of galaxies, star systems, quasars and other objects of scientific interest. The Space Telescope will do this by observing the sky from a nominal 550 kilometer low earth orbit via an optical system with a 2.4 meter diameter primary mirror. Additionally, this observatory has a precision pointing control system that is capable of maintaining a locked state on an object for extended periods accurately to within 0.01 arc seconds. The observatory instrument complement, optical system and pointing control system is presented.
