E-MAIL: Neil Square, Cornelius.Square.1@gsfc.nasa.gov. NASA/GSFC intends to issue a new work add on modification to Contract NAS5-32799 with Raytheon Optical Systems, Inc.(ROSI) for providing six latch sets; of which five will be flight qualified for use on HST SM4. ROSI developed, fabricated and tested the current HST Latch inventory and has the intimate design knowledge necessary to complete this new effort in the allotted time frame and constraints. The HST latch system is a highly specialized kinematic mounting system for HST instruments both in the Shuttle Bay and on HST itself. The latches are precision mechanisms that require dimentional tolerancing within .001 inch. The latch sets are asembled from several hundred unique parts (detailed in as many drawings) following an assembly process that requires the use of over 100 detailed step-by-step procedures that embody thousands of individual steps which are performed in aclass 10,000 clean room. The deliveries will be made in September 1999 through June 2001. This procurement is made under the authority of 10 U.S.C. 2304(c)(1) -- Only One Responsible Source. Any other firm seeking consideration should identify their capability to provide these latch Sets within 15 days of this publication to the GSFC Office and Individual listed above.
