E-MAIL: James S. King, James.S.King.1@gsfc.nasa.gov. NASA/GSFC is hereby soliciting information from potential sources for an energetic particle detector (EPD) to be flown aboard the six-month ST-5 Mission which is scheduled to launch in May 2003. The formal requirements and specifications for this instrument are currently being developed, but general characteristics of the instrument are as follows: ENERGETIC ION AND ELECTRON SPECTROMETER- Mature instrument (i.e., possessing flight heritage, with development limited to packaging/interface requirements); ion and electron spectrometer using solid-state and/or time-of-flight technology; mounted on spinning spacecraft (20 rpm; spin axis normal to plane of ecliptic) in ~200 km x ~35,786 km altitude orbit (i.e., GTO); minimum lifetime three months; radiation tolerant (100 krads total dose); operate from 5 volt spacecraft power bus; three flight units and one spare required. UTILIZATION- Characterization of high altitude energetic charged particle substorm injection events at altitudes above 25,000 km. FUNCTIONAL REQUIREMENTS- Minimum energy ranges: Ions 100 keV to 1 MeV, and Electrons 100 keV to 500 keV; energy resolution: <25%; mass analysis desireable, but not required; Particle Anisotropy in the plane of the ecliptic to be determined by sectored sampling synchronized to spacecraft spin phase; some measurement of angular dependence of particle flux out of the ecliptic is desireable, but not required. RESOURCES- Mass: ~1.5 kg; Power: ~1.5 W; Telemetry rate: ~1 kbps (orbit averaged). NASA/GSFC is interested in responses regarding both the industry capability/product availability to satisfy this requirement (in the form of documentation, literature, brochures, and references), as well as comment on the technical requirements as described above (feasibility, etc). Responses can be submitted by electronic mail to the primary POC, James King, designated below, or submitted by mail, to Mr. King, at the designated Contracting Office address. No solicitation exists; therefore, do not request a copy of the solicitation. If a solicitation is released it will be synopsized in the CBD and on the NASA Acquisition Internet Service. It is the potential offerors responsibility to monitor these cites for the release of any solicitation or synopsis. Tentatively, GSFC envisions the synopsizing of a solicitation shortly after receipt and evaluation of responses to this RFI. Please advise if the requirement is considered to be a commercial or commercial-type product. A commercial item is defined in Internet "Note A". This synopsis is for information and planning purposes and is not to be construed as a commitment by the Government nor will the Government pay for information solicited. Respondents will not be notified of the results of the evaluation. Respondents deemed fully qualified will be considered in any resultant solicitation for the requirement.
