E-MAIL: Carolyn S. Gonser, cgonser@pop200.gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Proposal (RFP5-12939-258) on a sole source basis to Raytheon STX Corporation pursuant to 10 USC 2304(c)(1)-Only One Responsible Source. This procurement will extend the period of performance under Contract NAS5-31760 for an additional 7-month extension. The extension period will be from September 1, 1999 through March 31, 2000. Three (3) one month options are included. This extension is required to : 1) meet critical milestones within the Laboratory for Terrestrial Physics; and 2) to allow for the consolidation of efforts with similar requirements within the Earth Sciences Directorate for the purpose of competition. This procurement is a continuation of specific specialized scientific and technical support which Raytheon STX provides to the Laboratory of Terrestrial Physics to advance NASA programs by promoting the increase in scientific knowledge of the Earth and planetary solid-body physics. The Laboratory for Terrestrial Physics is committed to specific and critical milestones regarding the delivery and/processing of scientific data, software, scientific analysis tools, and computer resources during the period from September 1, 1999 to March 31, 2000. Conducting a competitive solicitation during the 1999-2000 time frame, prior to the expiration of the proposed extension, would cause unacceptable delays to the affected missions/programs. These critical milestones include, but are not limited to: 1) in-flight calibration of the magnetometer and production of a joint main field model for the Oersted mission; 2) Phase II global gravity field model development as a joint effort between GSFC and DoD; 3) software simulations for the launch for the Shuttle Laser Altimeter-3; 4) calibration of altimetry data from TOPEX and Geosat follow-on launches including the analysis of the post-launch data; and 5) completion of arc tie capability in SOLVE software; the time dependent gravity effort is waiting for this feature. The support sought during this extension is a continuation of the work performed by Raytheon STX, under this contract, and is only intended to continue until follow-on contracts are competitively awarded. The statutory authority for this sole source procurement is 10 USC 2304(c)(1)-Only One responsible source. However, companies who believe they can provide these services without any detrimental impact to program schedules supported by this work, should identify their interest and capabilities within 15 days after publication of this synopsis. See Number Note (s): 22. Interested firms have 15 days from 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 receive after the 15 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 theproposed effort on a full and open competitive basis, based upon responses to this notice is solely within the discretion of the Government. An Ombudsman has been appointed. See Internet Note "B". The Government does not intend to acquire commercial items in accordance with FAR Part 12. See Note 26. Posted 07/29/99 (D-SN360840). (0210)
