E-MAIL: Kyle D. Cones, kcones@ems.jsc.nasa.gov. NASA/JSC plans to issue a sole source Request for Offer (RFO) for the development of a VME based Fault Tolerant Parallel Processing System for use in the X-38 spacecraft avionics system to provide real time redundancy and fault tolerance among all flight critical computers. This computer redundancy and fault tolerance must be transparent to the application programs (i.e. Guidance Navigation and Control (GN&C), Environmental Crew Life Systems Support (ECLSS), etc.). The hardware/software combination must provide the following critical Byzantine resilient features to the fault tolerant flight critical computer system: high-speed data exchange, processor synchronization/voting, reconfiguration during faulty conditions, and channel reinitialization and resynchronization upon transient fault (must be resilient to Single Event Upsets (SEU s)). The flight hardware and software must be radhardened and reside on conduction cooled VME (6U) boards. Non-flight hardware will be the commercial grade equivalent. This procurement is being conducted under the NASA MidRange Pilot Test Program approved by the Office of Federal Procurement Policy. NASA/JSC intends to purchase the system from Draper Laboratories. Draper Laboratories is the only known source identified with the ability to provide this technology in a radiation hardened, conduction cooled, VME based product that is adequate for the X-38 redundancy scheme. See Numbered Notes 22 and 26. Interested firms have 15 days from publication on the Commerce Business Daily (CBD) to submit 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 received after 15 days 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, on a full and open competitive basis, based upon responses to this notice, is solely within the discretion of the Government. All responsible sources may submit an offer which shall be considered by the agency. Any referenced numbered notes can be viewed at the following URL: http://genesis.gsfc.nasa.gov/nnotes.htm. (0135)
