C. Schwenk, J. A. Gilman, and J. B. Paige of Futron, Inc., Bethesda, MD. September 1992 SBIR - 91-2 NASA SBIR Abstracts of 1991 Phase I Projects Small Business Innovation Research Program Washington, DC 20546 Introduction Objective This document, Abstracts of 1991 Phase I Projects, describes the objectives of 301 projects placed under contract by the Small Business Innovation Research (SBIR) program of the National Aeronautics and Space Administration (NASA). These projects were selected competitively from among proposals submitted to NASA in response to the 1991 SBIR Program Solicitation. Contents The basic document consists of edited, non-proprietary abstracts of the winning proposals submitted by small businesses. The abstracts are presented under the 15 technical topics within which Phase I proposals were solicited. Each project has been assigned a sequential identifying number from 001 to 301, in order of its appearance in the body of the report. The document also includes Appendixes to provide additional information about the SBIR program and permit cross-reference of the 1991 Phase I projects by company name, location by state, principal investigator, NASA Field Center responsible for management of each project, and NASA contract number. The 1991 Phase I The closing date for the 1991 SBIR Phase I Program Solicitation was Projects August 8, 1991, at which time 2583 proposals had been received. Following evaluation and selection of proposals for contract negotiation, 6- month fixed-price contracts were placed for 301 projects with 243 small businesses in 34 states to determine the feasibility of the proposed innovations. All projects were conducted during calendar year 1992. It is planned that approximately half of the successfully completed Phase I projects will be chosen in late 1992 and early 1993 for continuation into Phase II proposals. Technical Topics The order of abstract presentation is according to technical topics. Since 1984, each NASA SBIR Program Solicitation has contained the following fifteen technical topics: 01 Aeronautical Propulsion and Power 02 Aerodynamics and Acoustics o3 Aircraft Systems, Subsystems, and Operations 04 Materials and Structures 05 Teleoperators and Robotics o6 Computer Sciences and Applications 07 Information Systems and Data Handling O8 Instrumentation and Sensors 09 Spacecraft Systerr_sand Subsystems 10 Space Power 11 Space Propulsion 12 Human Habitability and Biology in Space 13 Quality Assurance, Safety, and Check-Out for Ground and Space Operations 14 Satellite and Space Systems Communications 15 Materials Processing, Microgravity, and Commercial Applications in Space iii PP;6",_I)iNG p,_r;,_ _1 A,,_K "lOT RLMEI:, Subtopics Each technical topic contains a number of subtopics that specify the problems or opportunities to which small firms are invited to address Phase I proposals. The number and content of the subtopics change from year to year, depending on the interests of the agency. The SBIR Program Solicitation for 1991 included the 194 subtopics listed in Appendix B. Program Overall program management is provided by the Office of Commercial Management Programs in NASA Headquarters.

  • Messengers from Outer Space
    The complete absence of national laboratories for standardizing radiation measurements and the lack of physics departments in most radiotherapy centres in Latin America warrant the setting up of one or more regional dosimetry facilities, the functions of which would be primarily to calibrate dosimeters; to provide local technical assistance by means of trained staff; to check radiation equipment and dosimeters; to arrange a dose-intercomparison service; and to co-operate with local personnel dosimetry services. To be most effective, this activity should be in the charge of local personnel, with some initial assistance in the form of equipment and experts provided by the Agency. Although the recommendations were presented to the IAEA as the or­ ganization responsible for the setting up of the panel, the participants re­ commended that the co-operation of the World Health Organization and the Pan-American Health Organization should be invited. It was also suggested that the panel report be circulated to public health authorities in the countries represented. MESSENGERS FROM OUTER SPACE Although no evidence has yet been confirmed of living beings reaching the earth from space, it has been estimated that hundreds of tons of solid matter arrive every day in the form of meteorites or cosmic dust particles. Much is destroyed by heat in the atmosphere but fragments recovered can give valuable information about what has been happening in the universe for billions of years. Some of the results of worldwide research on meteorites were given at a symposium in Vienna during August. During six days of discussions a total of 73 scientific papers was present­ ed and a special meeting was held for the purpose of improving international co-operation in the research.

  • The Water on Mars Vanished. This Might Be Where It Went
    The water on Mars vanished. This might be where it went. timesofindia.indiatimes.com/home/science/the-water-on-mars-vanished-this-might-be-where- it-went-/articleshow/81599751.cms NYT News Service | Mar 20, 2021, 10:32 IST Mars was once wet, with an ocean’s worth of water on its surface. Today, most of Mars is as dry as a desert except for ice deposits in its polar regions. Where did the rest of the water go? Some of it disappeared into space. Water molecules, pummeled by particles of solar wind, broke apart into hydrogen and oxygen atoms, and those, especially the lighter hydrogen atoms, sped out of the atmosphere, lost to outer space. A tall outcropping of rock, with layered deposits of sediments in the distance, marking a remnant of an ancient, long-vanished river delta in Jezero Crater, are pictured in this undated image taken by NASA's Mars rover Perseverance. (Reuters) But most of the water, a new study concludes, went down, sucked into the red planet’s rocks. And there it remains, trapped within minerals and salts. Indeed, as much as 99% of the water that once flowed on Mars could still be there, the researchers estimated in a paper published this week in the journal Science. Data from the past two decades of robotic missions to Mars, including NASA ’s Curiosity rover and the Mars Reconnaissance Orbiter, showed a wide distribution of what geologists call hydrated minerals. “It became very, very clear that it was common and not rare to find evidence of water alteration,” said Bethany Ehlmann, a professor of planetary science at the California Institute of Technology and one of the authors of the paper.

  • Problems with Panspermia Or Extraterrestrial Origin of Life Scenarios As Found on the IDEA Center Website At
    Problems with Panspermia or Extraterrestrial Origin of Life Scenarios As found on the IDEA Center website at http://www.ideacenter.org Panspermia is the theory that microorganisms or biochemical compounds from outer space are responsible for originating life on Earth and possibly in other parts of the universe where suitable atmospheric conditions exist. Essentially, it is a hypothesis which states that life on earth came from outer space. It has been popularized in countless science fiction works, however some scientists, including the discoverer of the structure of DNA, Francis Crick, have advocated panspermia. There are generally about 3 different "flavors" of panspermia: 1. Naturalistic Panspermia where life evolves on another planet, and naturally gets ejected off the planet and come to rest on earth. 2. Directed Panspermia where intelligent life on other planets intentionally seeded other planets with their own form of life. 3. Intelligent Design Panspermia, where intelligent beings from another planet came to earth and designed life here. Each type of panspermia will be briefly discussed below: 1. Naturalistic Panspermia where life evolves on another planet, and naturally gets ejected off the planet and come to rest on earth. Naturalistic panspermia has gained popularity because some have recognized that life on earth appears very soon after the origin of conditions which would allow it to exist. Many scientists believed that if life had originated on earth it would have taken many hundreds of millions, or even billions of years to do so. Life appears perhaps less than 200 million after the origin of conditions at which life could exist.

Owning Outer Space Ezra J. Reinstein * I. INTRODUCTION What do we want from space? We want the knowledge we can gain from scientific research; we can learn much about the Earth and its inhabitants, as well as the universe around us, by studying space. We want to explore, to satisfy the thirst for adventure and conquest imagined in countless science fiction books and films. We want to improve our collective lot down here on Earth. Space offers the potential for practically limitless wealth, some already being exploited, some we may only harness in the distant future, and un- doubtedly some we cannot begin to guess. Already the wealth of space is being developed in the form of telecommunications and remote satellite ob- servation. The private-sector investment in telecommunications satellites alone was projected to total $54.3 billion (including launch) between 1996 and 20001 -- and this figure doesn't include other commercial space ven- tures, nor does it include investment in Russian and Chinese satellites.
