SOL RFP5-10677-271 DUE 091597 POC Wilma Mooney, Contracting Officer, Phone (301)286-9435, Fax (301)286-1739, Email Wilma.S.Mooney.1@gsfc.nasa.gov WEB: Click here for the latest information about this notice, http://procurement.nasa.gov/EPS/GSFC/date.html#RFP5-10677-271. E-MAIL: Wilma Mooney, Wilma.S.Mooney.1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Proposal (RFP), on a sole source basis in accordance with Federal Acquisition Regulation (FAR) 6.302-1, Only One Responsible Source, to obtain these services from General Sciences Corporation (GSC), 6100 Chevy Chase Drive, Ste. 200, Laurel, MD 20707, for a three month extension, 1/7/98 through 4/6/98, to the existing NASA Contract NAS5-32351. These services are a continuation of TRMM Science Data and Information System (TSDIS) maintenance, enhancement, and personnel training support services which require software analysis, system problem identification and analysis, software coding and testing, data analysis, system performance analysis and evaluation, science support, operations personnel training, program management and administrative support for the software development. This extension is required due to the delay of the TRMM launch, orginally scheduled for August 1997. The new launch date is scheduled for November 1997. The current contract includes 5 months of post-launch support for the optimal adaptation of the operational system performance and functional analysis, fine-tuning of system operational parameters, and SW modifications, as well as training of TSDIS operations and maintenance personnel during the same post-launch period. This support is a continuation of work performed by GSC, under this contract, for the past 4 years. Several agencies and organizations and more than 10 ground validation stations worldwide are committed to the specific and critical milestones regarding the delivery and processing of TRMM satellite science data, ground-based radar data, science algorithm validation, science data product verification, software, scientific analysis tools during the three month period, extending from 1/7/98 through 4/6/98. Please note that this specific TSDIS support will cease at the end of this extended contract period and there will be no follow-on support requirements. In accordance with Federal Acquisition Regulation (FAR) 6.302-1, Only One Responsible Source, NASA/GSFC intends to obtain these services from General Sciences Corporation (GSC), 6100 Chevy Chase Drive, Ste. 200, Laurel, MD 20707.
