The Faint Object Camera (FOC) is presently integrated as one of the five Scientific Instruments in the NASA Space Telescope (ST) which after an extensive integration and tests campaign should be launched in 1986. The Space Telescope is an observatory of 13 metres long, 4.3 metres diameter and 11,000 kilogrammes which will be placed by the Space Shuttle in a 500 kms circular orbit. The Faint Object Camera installed at the ST focal plane is a complex instrument with a total weight of 320 kgs and overall dimensions 1 x 1 x 2.2 metres. A Structural/Thermal Model (STM) and flight model of the FOC have been built. The FOC/STM was subjected to an extensive test program with for the mechanical part, sine and random vibrations, acoustic noise and modal test. On the FOC/PFM, acoustic noise only was applied for workmanship verification. With the FOC integrated now in the Space Telescope, and considering the specimen overall dimensions, limited mechanical testing will be applied at ST level which will consist of modal survey and acoustic noise. Then at the end of the test program, the overall assembly will be shipped to Kenndey Space Center and launched.
