99 -- IN SPACE TECHNOLOGY EXPERIMENTS PROGRAM SOL W-OSAT-1-92 POC Michael D. La Beau tel: 202/358-0433/John Landers (202) 358-4671 Technical P.O.C. ANNOUNCMENT OF OPPORTUNITY FOR FLIGHT EXPERIMENTS FOR THE IN-SPACE TECHNOLOGY EXPERIMENTS PROGRAM (IN-STEP). The National Aeronautics and Space Administration (NASA) Office of Space Access and Technology (OSAT) intends to continue, under Announcement of Opportunity (AO) No: W-OAST-1-92, released November 16, 1992, ''down-select'' from these participants and make awards for Phase B exploration of design concepts, preliminary design reviews (PDRs) efforts for flight experiments which will be used as a continuous ''down-selection'' process that will then lead to the subsequent Phase C/D solicitation and award of flight experiments. Solicitations for this Phase B is opened to those U.S. Organizations which have successfully completed Phase A, under NASA AO No: W-OAST-1-92, or to those which can otherwise demonstrate that they satisfy the requirements of AO no: W-OAST-1-92 for an equivalent mature development of flight experiments. This Phase B will validate and verify advanced space technology PDRs in one or more of the following areas: (1) sensors and sensor cooling; (2) vibration isolation; (3) space materials, coatings and environmental effects; (4) space communcations; (5) in-space construction and maintenance; (6) cryogenic fluids; and (7) space power. This AO is opened to U.S. industries, U.S. universities, NASA Centers, and other U.S. institutions; and presents an additional opportunity for U.S. university students submitting proposals for a separate class of low-cost IN-STEP Student Experiments. The inclusion of the student investigators will augment, and not eliminate, or exclude, the participation of other offerors from the objectives of this AO. Proposed space technology flight experiments are expected to be conducted using the Space Shuttle, expendable launch vehicles (ELVs), sub-orbital sounding rockets, or piggyback options on other space plateforms. This AO will result in approximately 20 Phase B awards. This is a phased-type procurement. For those who can otherwise demonstrate that they satisfy the requirements of AO No: W-OAST-1-92 for an equivalent mature development of flight experiments, you have forty-five (45) calendar days from the date of this announcement to submit a proposal for consideration to this Phase B effort. A request for a copy of the Phase B criteria can be made to: NASA Headquarters, Office of Space Access and Technology, Code XF, Attn: John Landers, Washington, DC 20546, Phone Number (202) 358-4671.
