A -- R -- SPACECRAFT STUDY FOR THE BURST ARC SECOND IMAGING SPECTROSCOPY (BASIS) MISSION UNDER THE SMALL EXPLORER ANNOUNCEMENT OF OPPORTUNITY SOL RFO5-00217/238 DUE 021997 POC Darlene Walter, Contracting Officer, (301) 286-4239 Bradley J Poston, Contracting Officer (301) 286-6843. 17. R -- NASA/GSFC intends to issue Request for Offer (RFO)5-00217/238 on a full and open competitive basis for a spacecraft study effort. This effort is in support of GSFC's forthcoming proposal submission for the Burst Arc Second Imaging Spectroscopy (BASIS) spacecraft in response to NASA Headquarters' upcoming Small Explorer Announcement of Opportunity (AO), which is scheduled to be released on March 7, 1997. A copy of the draft Small Explorer AO is available on the World Wide Web at: http://www.hq.nasa.gov/office/oss/research.htm. The BASIS Mission will focus on detection and origin of gamma ray burst. The basic requirement is for a preliminary spacecraft study effort in support of GSFC's Step 1 proposal for the BASIS mission. This effort will include providing a preliminary spacecraft concept and support of a red team review of the Step 1 proposal. In addition to the basic requirement, there will be two options. Option 1 is for support of a Step 2 proposal for the BASIS Mission. Option 1 will only be exercised if the Step 1 proposal is selected for further consideration. Option 1 requires a spacecraft design concept with a maturity level equivalent to a Phase A study with supporting analyses, trade studies, risk identification, and participation in the instrument/spacecraft trade studies. Option 1 will also include contractor participation in red and blue team reviews of the Step 2 proposal. Option 2 requires a full Phase B study effort. Option 2 will only be exercised if the Step 2 proposal is selected for further consideration. The Option 2 effort will include the development of a baseline flight design (flight and ground), identification of all interfaces, preliminary interface control documents, design specifications for all subsystems and breadboard any high risk items. The Option 2 effort will require the following plans: Facility Plans, Fabrication Plans, Verification Plans, Contamination Plans, Product Assurance Implementation Plans, Integration and Test Plans and Configuration and ControlPlans. NASA/GSFC plans to award a firm fixed price study contract with two firm fixed price options. This effort will be performed primarily at the Contractor's facility. The resulting firm-fixed-price contract will be for $25,000, Option 1 will be for $200,000, and Option 2 will be $2,000,000. The RFO is scheduled to be released on or before January 22, 1996. Proposals will be due approximately four weeks after the RFO release date. We anticipate a contract award date of March 23, 1997. Interested parties shall submit a written request for a copy of the RFO to Ms. Darlene Walter within 15 days of the publication of this synopsis to the address listed above. All responsible concerns may submit a proposal which will be considered by NASA/GSFC. (0358)
