Summaryedit

Description
Français : Les ingénieurs inspectent la surface du miroir primaire dans les locaux de son fabriquant Perkin-Elmer
English: This photograph shows engineers inspecting the Hubble Space Telescope's (HST's) Primary Mirror at the Perkin-Elmer Corporation's large optics fabrication facility. After the 8-foot diameter mirror was ground to shape and polished, the glass surface was coated with a reflective layer of aluminum and a protective layer of magnesium fluoride, 0.1- and 0.025- micrometers thick, respectively. The purpose of the HST, the most complex and sensitive optical telescope ever made, is to study the cosmos from a low-Earth orbit. By placing the telescope in space, astronomers are able to collect data that is free of the Earth's atmosphere. The Marshall Space Flight Center had responsibility for design, development, and construction of the HST and the Perkin-Elmer Corporation, in Danbury, Cornecticut, developed the optical system and guidance sensors.
