McGrath, Contracting Officer, Phone (301)286-8085, Fax (301)286-1670, Email Michael.E.McGrath.1@gsfc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.msfc.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=D&pin=51#RFO5-53452-360. E-MAIL: Lorrie L. Eakin, Lorrie.L.Eakin.1@gsfc.nasa.gov. NASA is planning future large space observatories as part of the Astronomical Search for Origins and Planetary Systems theme and the Structure and Evolution of the Universe theme in the Space Science Enterprise. One of the key technology needs common to a number of them is the capability to reliably cool detectors and associated components to temperatures as low as 5K for an extended mission duration. For this reason, two nearer term missions from the ASO theme, the Next Generation Space Telescope (NGST), and the Terrestrial Planet Finder (TPF) plan to jointly fund the development of cooler technology. NASA/GSFC's goal in this procurement is to develop a mature cryocooler system technology that can be appropriately packaged to meet NGST's near-term requirements. NASA/GSFC plans to issue a draft Statement of Work via the internet, on or about July 21, 2000. This document is for information and planning purposes and to allow industry the opportunity to verify reasonableness and feasibility of the requirement, as well as promote competition. Prospective offerors are invited to submit comments or questions to: Lorrie L. Eakin at Mail Code 214.1, no later than July 28, 2000. In responding reference RFO5-53452-360. NASA/GSFC is particularly interested in any comments regarding the definition at Section 5.1, Breadboard Model, with respect to the use of existing hardware to assemble a more flight-like breadboard. In addition, any comments regarding the cooling requirement at Section 4.1, Cooling, and Table 1, Mid-IR Cooling System Specification, with respect to the viability of the proposed technology given a factor of two decrease (or increase)in the cooling power. In addition to this procurement, NASA/GSFC intends to explore, in parallel, the possibility of an in-house capability to satisfy NGST's near-term requirements through technology development at NASA's Jet Propulsion Laboratory (JPL). At the conclusion of the procurement, a final make or buy decision shall be made. NASA/GSFC intends to use all available resources within NASA and other government agencies to evaluate private industry's capabilities to meet said requirements, including any such resources available through NASA's JPL. Comments may be forwarded to Lorrie L. Eakin via electronic transmission or by facsimile transmission. Ms. Eakin's e-mail address is: Lorrie.L.Eakin.1@gsfc.nasa.gov, and her facsimile number is (301) 286-1779. This solicitation/synopsis is not to be construed as a commitment by the Government, nor will the Government pay for the information solicited. Respondents will not be notified of the results of the review. Any questions regarding this announcement should be directed to the identified point of contact. An ombudsman has been appointed -- See Internet Note "B". The solicitation and any documents related to this procurement will be available over the Internet. These documents will be in Microsoft Office Suite (Word 6.0, Excel 5.0, or PowerPoint 4.0) format and will reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application.
