A -- REMOTE SENSING MISSION TO MEASURE TROPOSPHERIC POLLUTION AND AEROSOLS SOL RFP5-61102/252 DUE 051596 POC Mary Petkoff, Contracting Officer, 301-286-6143. This is a notice of intent to issue Request For Proposal (RFP)5-61102/252 for a Goddard Space Flight Center (GSFC) requirement to select a partner to support the development of a proposal to respond to an expected NASA Announcement Of Opportunity (AO) for the Earth Science System Pathfinder (ESSP) Program. The initial concepts for ESSP are available on the Internet at http://www.hq.nasa.gov/office/mtpe/esspcbd.html and http://www.hq.nasa.gov/office/mtpe/esspcbd.html. This AO is focused toward high priority Earth Science not already addressed by on-going planned missions. The Goddard ESSP proposal will focus on a low cost mission including instruments, spacecraft, launch vehicle, two years of mission operations, and data analysis to measure tropospheric pollution and stratospheric tropospheric exchange. The remote sensing mission would include measurements of ozone, sulfur dioxide, dust, smoke, aerosols, thin cirrus, and polar stratospheric clouds. Profiles, in the 10-30 km range, of gases needed to understand tropospheric stratospheric exchange would also be surveyed. Observations would be made in the nadir and the limb in the ultraviolet, visible, and near infrared with one or more instruments. Additional information about this requirement may be obtained by consulting the sources sought synopsis released on March 21, 1996. A single fixed-price incentive contract, containing two phases is contemplated. The first phase will require the contractor to assist in the development of an AO, on a no-exchange-of-funds basis. The second phase will be a priced option to require the contractor to design two instruments and spacecraft, build and integrate them and two Government furnished instruments, assist in the integration with the Government furnished launch vehicle, and provide two years of mission operations. The second phase option will only be exercised if the remote sensing mission to measure tropospheric pollution and aerosols is selected under the ESSP AO. Solicitation release is planned for on or about April 8, 1996. It is expected that a ESSP AO procurement library will be available from the time of solicitation release through the proposal due date. Access to the bidder's library would be available by appointment only. Any firms interested in receiving RFP5-61102/252 should send or FAX (FAX number 301-286-1739) their request to NASA/Goddard Space Flight Center, Code 219, Attn: Ms. Mary Petkoff, Greenbelt, MD 20771, or send their request via Internet to mary.petkoff@gsfc.nasa.gov. Those firms who repond in writing or via Internet to the sources sought synopsis are automatically on the mailing list for the RFP and need not submit a separate request. (0081)
