E-MAIL: A. Carol Terrell, Carol.Terrell@msfc.nasa.gov. NASA/MSFC plans to issue a Request for Quotation (RFQ) for a research study entitled "Micrometeroid Testing of Shield Materials". This study is being procured under the University Research Basic Ordering Agreement (BOA)Program with the university community within the United States. The intent of this work is to proceed with studying the effects of micrometeoroid impacts on potential sun shield materials/configurations to be utilized in the design of the Next Generation Space Telescope (NGST). The Contractor shall perform the following tasks: 1. Perform a combination of testing plus analyses. Hypervelocity impact tests and carefully documented results, including streak camera negatives, are needed. A jointly agreed-to test procedure will be utilized. The (NGST) candidate sun shield materials/configurations to be tested will be provided. A total of 25 shots are estimated to be required. The work is targeted to be complete before January, 2000, but must be completed no later than March, 2000. The range ofparameters for the tests is as follows: Projectile density: 0.5 -- 8 g/cc Projectile diameter: 50 -- 400 microns Projectile velocity: 3 -- 14 km/sec Impact angle: 0-75 degree (from the velocity vector) The tests must be conducted in a chamber at a minimum vacuum of 10-5 torr. The test items must be protected from contamination of particulates, other than the debris created from the shot, both before and after the test. Any special test item holding fixtures required will be provided. After impact testing, post-test analyses, and the documenting of the results, the test items will be bagged (such that nothing can touch the front or rear of the impact areas), sealed, cushion packaged, and held for MSFC pickup (only in extraordinary circumstances may shipment be required) for further analysis. The following data, as a minimum, is required for each test: Projectile impact parameters (diameter, velocity, impact angle) Streak Camera negatives or clear copy (from which the above is derived) Post test photograph of the test item (front and rear) Close up photograph of impact crater (front and rear) Impact crater/hole dimensions (diameter, depth if applicable) Damage area dimensions This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/MSFC intends to purchase the Research Study from Auburn University's Space Power Institute under the Research BOA Program. This sole source action is pursuant to FAR 13.106 and is based on the University's domain expertise in this area of research. Interested firms have 15 days from the publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after the 15 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government to not compete this proposed effort on a full and open competitive basis, based upon responses to this notice is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. OMBUDSMAN STATEMENT REQUIRED] An Ombudsman has been appointed. See Internet Note "B". Posted 04/21/99 (D-SN322902). (0111)
