Farr, Tom G.; Kobrick, Mike, 1996, "(abstract) The Shuttle Radar Topography Mapper", https://hdl.handle.net/2014/26415, Zurich, Switzerland, JPL Open Repository
The Shuttle Radar Topography Mapper (SRTM), is a cooperative project between NASA and the Defense Mapping Agency of the U.S. Department of Defense. The mission is designed to use a single-pass radar interferometer to produce a digital elevation model of the Earth's land surface b... |

Devereaux, Ann, 1996, "(abstract) The Role of the Deep Space Network for Cassini", https://hdl.handle.net/2014/27494, Bologna, Italy, JPL Open Repository
Cassini radio science experiments have several categories of requirements for DSN tracking services. The three main areas for upgrade are in Ka-band, long-term frequence stability, and short-term frequency stability/phase noise level. |

Alkalaj, Leon; Panwar, Ramesh, 1993, "(abstract) The Nest Generation of Space Flight Computers", https://hdl.handle.net/2014/35284, Anaheim, CA, JPL Open Repository
To meet new design objectives for drastic reductions in mass, size, and power consumption, the Flight Computer Development Group at JPL is participating in a design study and development of a light-weight, small-sized, low-power 3-D Space Flight Computer. In this paper, we will p... |

Beichman, Charles, 1994, "(abstract) The IRAS All-Sky Survey: Scientific and Technical Lessons Learned", https://hdl.handle.net/2014/34501, Hamburg, Germany, JPL Open Repository
Although the Infrared Astronomy Satellite (IRAS) was launched over 10 years ago, the IRAS legacy of catalogs, images, and data archives remains a vital source of information on the infrared sky. Over 4000 papers in the refereed literature have used IRAS data, and this number cont... |

Feynman, J.; Martin, S. F., 1993, "(abstract) The Initiation of Quiescent-Filament Associated Coronal Mass Ejections by New Active Regions", https://hdl.handle.net/2014/35950, San Francisco, CA, JPL Open Repository
We will present observational evidence that the eruption of filaments and coronal mass ejections (CMEs) occur as a consequence of the destabilization of large scale coronal arcades due to newly emerging magnetic flux reconnecting with the preexisting arcades. |

Weissman, Paul R.; Stern, S. Alan, 1993, "(abstract) The Impactor Flux in the Pluto-Charon System", https://hdl.handle.net/2014/35453, Flagstaff, AZ, JPL Open Repository
The impactor flux on Pluto and Charon consists of long-period comets from the Oort cloud passing through the region, and intermediate-period comets evolving inward to (or outward from) short-period orbits. The source of the intermediate-period comets is likely an extended disk of... |

Deutsch, Leslie J., 1997, "(abstract) The Galileo Spacecraft: A Telecommunications Legacy for Future Space Flight", https://hdl.handle.net/2014/27498, Padova,Italy, JPL Open Repository
The Galileo mission to Jupiter has implemented a wide range of telecommunication improvements in response to the loss of its high gain antenna. While necessity dictated the use of these new techniques for Galileo, now that they have been proven in flight, they are available for u... |

Carsey, Frank D., 1996, "(abstract) The Evolving Spaceborne Radar Data Support to Earth Science and Operations at the Alaska SAR Facility", https://hdl.handle.net/2014/27630, San Francisco, CA, JPL Open Repository
The Alaska SAR Facility (ASF) has been receiving, processing, archiving, and distributing data for Earth scientists and operations since it began receiving data in 1991. Four radar satellites are now being handled. Recent developments have served to increase the level of services... |

Way, JoBea, 1993, "(abstract) The EOS SAR Mission: A New Approach", https://hdl.handle.net/2014/34933, Tokyo, Japan, JPL Open Repository
The goal of the Earth Orbiting System Synthetic Aperture Radar (EOS SAR) program is to help develop the modeling and observational capabilities to predict and monitor terrestrial and oceanic processes that are either causing global change or resulting from global change. Specific... |

Baines, Kevin H.; Mickelson, M.E.; Larson, L.E., 1994, "(abstract) The Distribution of Carbon in the Outer Solar System: New Constraints on Planetary Formation Mechanisms from Groundbased Spectroscopic Observations of Uranus and Neptune", https://hdl.handle.net/2014/34486, Pasadena, CA, JPL Open Repository
New limits on the methane mixing ratio within the well-mixed tropospheres of Uranus and Neptune place significant constraints on planetary formation mechanisms within the outer solar system. Our results support the conclusion of other researchers that a nontrivial amount of metha... |
