A -- A-REMOTE SENSING MISSION TO MEASURE TROPOSPHERIC POLLUTION AND AE ROSOLS POC Mary Petkoff, Contracting Officer, 301-286-6143. NASA's Goddard Space Flight Center (GSFC) will be seeking 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/essp.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. A single fixed-price incentive contract, containing two phases is contemplated. The first phase will require the contractor to assist in the development of a proposal to respond to the 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 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. The Request For Proposal and any resulting contract will emphasize performance based requirements and specifications. A draft statement of work and specifications are available at the Internet address http://ssbuv.gsfc.nasa.gov/essp.html. Interested parties should provide comments by March 29, 1996, in writing to NASA/Goddard Space Flight Center, Code 219, Attn: Mary Petkoff, Greenbelt, MD 20771; or via Internet to mary.petkoff@gsfc.nasa.gov. Additionally, interested parties should provide a brief statement of intent; describing the organization's technical expertise, capabilities, past experience, and motivation for participating in this endeavour. This request does not commit the Government to pay any cost incurred in the submission of any response to this request. (0079)
