93 -- ADVANCED DEVELOPMENT OF A FLEXIBLE RADIATOR SOL 9-BE13-09-7-84P DUE 083097 POC Lisa Rea-Phillips, Contracting Officer, Phone (281) 483-8395, Fax (281) 244-5337, Email lreaphil@ems.jsc.nasa.gov WEB: Click here for the latest information about this notice, http://procurement.nasa.gov/EPS/JSC/date.html#9-BE13-09-7-84P. E-MAIL: Lisa Rea-Phillips, lreaphil@ems.jsc.nasa.gov. NASA/JSC plans to issue a Request for Offer (RFO) for an initial 4 month study focused on designing lightweight, flexible radiators that will attach to the outside of the envisioned interplanetary transit habitat. The transhab vehicle is launched to Earth orbit aboard the Space Shuttle, deployed from the payload bay, and inflates prior to human habitation and trans-mars injection. The design of the body-mounted radiators must address the unique requirements of this Martian vehicle including such issues as attachment and compatibility with inflation techniques while maintaining the ability to reject 20 kW using the available 180 m2 external area. Additionally, these radiators must strive to achieve a mass goal of 3.75 kg/m2 and minimize pressure drop. Following the phase 1 design work, an optional phase 2 may be implemented. The phase 2 effort will be an 8 month period of performance that includes material development and fabrication of a prototype radiator which will be tested in thermal/vacuum conditions at NASA/JSC. Multiple contracts will be awarded for the Phase 1 system design stage with down selection envisioned for the Phase 2 fabrication stage. This procurement is being conducted under the NASA MidRange Pilot Test Program approved by the Office of Federal Procurement Policy. The Government does not intend to acquire a commercial item using FAR Part 12. See Numbered Note 26. All responsible sources may submit an offer which shall be considered by the agency. The anticipated release date of the RFO is on or about 8/1/97 with an anticipated offer due date of on or about 8/30/97. An ombudsman has been appointed -- See Note "B". The solicitation and any documents related to this procurement will be available over the Internet. These documents will be in MS-Word format and will reside on a World-Wide Web (WWW) server, which may be accessed using a WWW browser application.
