E-MAIL: Janice M. Stewart, janice.stewart@msfc.nasa.gov. NASA/MSFC plans to issue a Request for Offer (RFO) for Auroral, Polar Cap, and Polar Cusp Modeling and Data Analysis in support of the IMAGE Mission and LENA Instrument to include the following: MSFC has the responsibility to perform specific modeling, theoretical analysis, and data analysis in support of the IMAGE Mission. The responsibility was acquired when MSFC was selected to participate in a proposal under the NASA Announcement of Opportunity AO-95-OSS-02. The proposal is specifically identified to provide support in performing theoretical and data analysis for the LENA instrument, which is part of the IMAGE Mission. The IMAGE spacecraft is scheduled for launch in January 2000. The required research will be conducted both in advance of the launch and following the launch. Statement of Work Tasks: The contractor shall perform the following tasks: BASIC (Tasks 1-4) 1. Add the low energy component of the precipitating ring current H+ and O+ ions as well as precipitating cusp H+ ions to the existing Wilson model which represents upflowing ionospheric ions. 2. Evaluate evidence for the altitude at which upflowing ions are energized. Produce modified estimates of upflowing ion fluxes and the consequent effect on low-energy neutral atom flux from low altitudes. 3. Work with (Auburn University) to develop tomographic inversion techniques to be used in the interpretation of LENA remote measurements. Specifically, develop a relationship that can be used to represent ion pitch angle distributions along high latitude field lines, which is a function of the pitch angle distribution defined at only one altitude. 4. Provide estimates of low energy neutral atom fluxes that will be seen by the LENA instrument as needed by the LENA instrument team lead investigator. Period of Performance The basic period of performance for this effort shall be one year contract award with 4 one-year options. Use of Government Facilities and Property During visits to NASA/MSFC, the government shall provide access to computer equipment in support of the IMAGE Theory and Modeling activity in the MSFC Space Sciences Laboratory, Building 4481. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. Interested firms have 7 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 7 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. Firm date for receipt of offers will be stated in the RFO. This is a 100% Small Business Set-Aside. Any referenced notes can be viewed at the following URL: http://genesis.gsfc.nasa.gov/nnotes.htm.
