99 -- SMALL LAUNCH VEHICLE SERVICES REQUEST FOR INFORMATION/SOURCES SO UGHT POC Michael E. McGrath, Contracting Officer, 301-344-4871. The National Aeronautics and Space Administration (NASA) is seeking expressions of interest from industry regarding their capability to satisfy potential near-term and future launch service needs for NASA small class scientific payloads. The types of missions which may be needed include the following: Type 1 - 340 x 955 km., i = 99.3 deg., minimum separated mass = 295 kg; Type 2 - 350 x 4200 km., i = 83.0 deg., minimum separated mass = 190 kg; Type 3 - 600 x 650 km., i = 70.0 deg., minimum separated mass = 295 kg; Type 4: 550 x 510 km., i = 38.0 deg., minimum separated mass = 365 kg; Type 5 - 600 km. circular, i = 97.8 deg., minimum separated mass = 250 kg; and, Type 6: 550 x 510 km., i = 38.0 deg., minimum separated mass = 190 kg. Parties possessing the capability to launch any or all of the mission types described above are invited to respond to this synopsis and are requested to submit a capabilities statement describing your approach and experience with launch systems. Specifically, provide launch vehicle data including a general description of launch vehicle capabilities, stage of launch vehicle development/production, launch history, launch sites, a schedule for the earliest possible launch opportunity, and an overall risk assessment for meeting your proposed schedule. In addition, describe your capabilities to satisfy NASA's long term launch needs in the small payload class as described above. NASA is interested in innovative technical and business approaches to ensure that launch support is available when needed to carry out its mission. This is a request for information only and should not be construed as a commitment by the Government to enter into a contract for the above described launch services. Responses may be submitted by FAX to (301) 344-8629 or by mail to the Contracting Officer listed above at mail code 284.9. Responses must be submitted within ten (10) days of the publication date of this synopsis. Electronic versions of the documents will be provided on the World Wide Web at http://genesis.gsfc.nasa.gov/procure.htm, and by anonymous ftp to genesis.gsfc.nasa.gov/public/solicita. (0180)
