E-MAIL: Lori M. Levine, llevine@pop200.gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Proposal (RFP) for a one-year extension on a sole-source basis under NAS5-32350. NASA/GSFC intends to purchase the services from Hughes (Raytheon) HSTX Corp., who currently supports the GSFC providing Space and Earth Science Data Analysis (SESDA) services, based upon 10 U.S.C. 2304 (c)(1) Only One Responsible Source and 10 U.S.C.2304 (d)(1)(B), Unacceptable Delays. The contract with HSTX started October 1, 1993 and will expire on September 30, 1999. This extension is a continuation of activities associated with solar and space plasma physics, astrophysics and astronomy, planetary studies, atmospheric science and climatology, oceanography, geodynamics, and solid earth dynamics. To date, over 160 active task orders support the Science and Engineering Directorates at GSFC. Work is underway to compete the present requirement on a full and open competition basis. The selection of a successor contractor and phase-in is expected during this one-year extension period. Only HSTX is intimately familiar with the 160+ tasks currently being performed under NAS5-32350. Potential replacement of the incumbent at this time introduces unacceptable risks to the completion of critical milestones within already established schedules. In addition, HSTX possesses unique knowledge and expertise not possessed by other vendors at this time including detailed understanding of complex science algorithms for mission critical software, preparation for science launch support for Earth science instrument missions (such as Earth Observing System) and resolution of the Year 2000 issues across the full range of software supported. However, companies that believe they can provide these services for this period without any detrimental impact to the program schedules supported under NAS5-32350 should fully identify their interest and capabilities within 15 days after publication of this synopsis on the NAIS or Commerce Business Daily. These capability statements will be used solely for the purpose of determining whether or not to conduct this contract extension on a competitive basis. Responses to the synopsis received after 15 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government not to compete this proposed contract extension on a full and open basis, based upon responses to this notice, is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice. See Note 22. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26.
