Scientific paper

The evolution of the Hubble Space Telescope (HST) project, and the observatory structure and its capability are described. The HST has three major systems: the optical telescope assembly, which collects the light and forms an image; the scientific instruments, which use the image to generate astronomical data; and the support-systems module, which allows the other two systems to function as a complete observatory. The configuration concept of the primary and secondary mirrors allows the HST to obtain diffraction-limited images over a field of view much larger than that of any other imaging detector foreseen for the next decade. The faint object camera is able to record with a resolution of about 0.03 arcsecond. The HST should be able to detect stars at least 30 times fainter than the Hale telescope does. The lifetime of the observatory is expected to be 15 years, with the key components designed to be replaced in orbit. Detailed technical data are included.
