Editor's Note, Padraig O'Malley

New England Journal of Public Policy

Four years ago, in the 1988 Summer/Fall issue of the New England Journal of Public Policy, we wrote,

"[The two] presidential candidates, Michael Dukakis and George Bush, [proved] themselves extraordinarily adept time and again at not addressing any of the excruciatingly difficult choices a new administration will have to make. But the realities the new president will face cannot be indefinitely obscured. The prosperity we enjoy, the unparalleled splurge in consumption during the 1980s, has been fueled by borrowing against the future. Although this observation is not especially new — and repetition has robbed it of urgency — what …

Technologies For Future High Capability Micro-Milsatcom Systems, B. Steele, R.J. Bonometti, A. Wallace, K. Brandt

Small Satellite Conference

Satellite communications systems are a vitally important component of our Defense infrastructure for both tactical and strategic missions. In particular, satellite communications (whether military or commercial) have become increasingly important to support tactical operations, as was clearly demonstrated during Operations Desert Shield and Desert Storm. In the emerging doctrinal shift to a CONUS-based force structure with capabilities for rapidly responsive lethal power projection to meet global crises, the vital necessity for SATCOM to provide an omnipresent communications infrastructure for immediate support of the developing theater will become a key element in the successful realization of our new warfighting strategy. This …

Near Earth Asteroid Rendezvous, Edward Reynolds, Robert Farquhar

Small Satellite Conference

The Johns Hopkins University Applied Physics Laboratory recently completed a pre-Phase A study to design a spacecraft to rendezvous and go into orbit around a near earth asteroid. The spacecraft would map the asteroid's surface and collect other science data for a one year period. The primary mission would be a rendezvous with either asteroid Anteros or with asteroid 1982XB. Presently, the APL NEAR spacecraft is beginning Phase A study. This paper identifies the science objectives and mission goals, outlines the mission scenario, and concludes with a description of the APL NEAR pre-Phase A spacecraft.

Exploration Of Pluto: Search For Applicable Small Satellite Technology, Robert Staehle, John Carraway, Christopher Salvo, Richard Terrile, Stacy Weinstein, Elaine Hansen

Small Satellite Conference

Pluto is the last known planet in our Solar System awaiting spacecraft reconnaissance. In its eccentric orbit taking it 50 AU from the Sun, Pluto presently has a thin atmosphere containing methane, which is projected to "collapse" back to the icy planet's surface in about three decades, following Pluto's 1989 perihelion pass at 30 AU. Based on ground and Earth-orbit-based observing capabilities limited by Pluto's small size and extreme distance, present top-priority scientific questions for the first mission concern Pluto and Charon's surface geology, morphology and composition, and Pluto's neutral atmosphere composition. Budgetary realities preclude a large, many-instrument flyby spacecraft, …

Copernicus - Lunar Surface Mapper, Frank Redd, Shaun Anderson

Small Satellite Conference

The Utah State University (USU) 1991-92 Space Systems Design Team has designed a Lunar Surface Mapper (LSM) to parallel the development of the NASA Office of Exploration lunar initiatives. USU students named the LSM "Copernicus" after the 16th Century Polish astronomer, for whom the large lunar crater on the face of the moon was also named. The top level requirements for the Copernicus LSM are to produce a digital map of the lunar surface with an overall resolution of 12 meters (39.4 ft). It will also identify specified local surface features/areas to be mapped at higher resolutions by follow-on missions. …

Mapping Of Earth's Magnetic Field With The Ørsted Satellite, W.R. Baron, K. Leschly, P.L. Thomsen

Small Satellite Conference

The Danish Ørsted satellite will carry three science experiments with the objectives of mapping the Earth's magnetic field and measuring the charged particle environment from a 7801an altitude sun-synchronous polar orbit. The science data generated during the planned one year mission will be used to improve geomagnetic models and study the auroral phenomena. Comprehensive and accurate mapping of the geomagnetic field every 5 to 10 years is of particular interest to geophysical studies. As such, the Ørsted science data return will complement the Magsat (1979-80) and Aristoteles (=2000) mission objectives. Two magnetometers will be mounted on an 8 meter long …

Navy/Marine Corps Demonstrations Of The Darpa Microsats, Walter Daniel, Robert Bruninga

Small Satellite Conference

Demonstrations of the DARPA Microsats with an emphasis on Navy and Marine Corps applications were conducted by personnel at the United States Naval Academy. These satellite communications demonstrations used the analog FM mode of the Microsats. Radios used were military transceivers, transmitters composed of laboratory signal generators with broadband power amplifiers, a modified amateur radio UHF transmitter, and commercially-available scanner receivers. Voice demonstrations included equipment checks with DARPA personnel, a tactical exercise at a Marine Corps base, and communications with a U.S. Navy destroyer. Position and status report data beacons were relayed through the Microsats from training vessels to Annapolis. …

Microsat Constellation Control Techniques, Keith Reiss

Small Satellite Conference

The first air-launched constellation of seven small experimental communications satellites into an unexpectedly low earth orbit (246 nmi X 192 nmi) resulted in a set of tough flight control demands. In the abbreviated demonstration mission the flight operations team was challenged in rapidly propelling the spacecraft into a useful uniform distribution about the orbit plane and in maintaining the "stations" under adverse conditions. The constellation was injected in perfect order and began mission operations immediately. However, each spacecraft's attitude control system coupled with the force of heavy atmospheric drag to produce variable in-plane phase drifts that required constant observation and …

Chemical Release Observation Program Description And Flight Results, Stephen Nichols, Jeffrey Wise, Ian Strong

Small Satellite Conference

The Chemical Release Observation (CRO) program developed three small satellites that were deployed from the Shuttle on flight STS-39. These were small experimental satellites built with a minimum of paperwork. While meeting all the necessary NASAISTS requirements. Each satellite contained a chemical (either hydrazine or an oxidizer) which was released on ground command. The satellites were approximately 18" diameter and 31" high. and weighed 160 to 195 pounds when loaded. The satellites carried 60 pounds of MMH (MonoMethyl Hydrazine), 52 pounds of UDMH (Unsymmetrical DiMethyl Hydrazine) and 11 pounds of N10 4 (Nitrogen Tetroxide). The satellites were designed and built …

Attitude Determination By Image Processing Algorithms, Hans Konigsmann, Hans Rath, Hartmut Renken

Small Satellite Conference

To determine attitude or direction with star constellations is perhaps the oldest method in the field of navigation and control. Besides its accuracy, star constellations can give three axis information by using just a single sensor, a digital CCD camera. What is very easy for men looking at the stars turns out to be complex if done by an onboard computer. The process of star identification can be divided into two parts: object segmentation and, needing much more calculation time, the matching process. Matching can be explained as comparing a star catalog stored in a computer memory with identified objects …

Red Butte Canyon Research Natural Area: History, Flora, Geology, Climate, And Ecology, James R. Ehleringer, Lois A. Arnow, Ted Arnow, Irving B. Mcnulty, Norman C. Negus

Great Basin Naturalist

Red Butte Canyon is a protected, near pristine canyon entering Salt Lake Valley, Utah. It contains a well-developed riparian zone and a perennial stream; hillside vegetation ranges from grasslands on the lower limits to Douglas-fir and aspen stands at the upper elevations. In this paper we describe the history of human impact, natural history aspects of climate, geology, and ecology, and faunal and floral information for key species in the canyon. The role and importance of Research Natural Areas is discussed, particularly with respect to the need to protect Red Butte Canyon—one of the few remaining undisturbed riparian ecosystems in …

Soil Loosening Processes Following The Abandonment Of Two Arid Western Nevada Townsites, Paul A. Knapp

Great Basin Naturalist

Soil compaction was measured at four sites within two abandoned mining camps in the western Great Basin Desert, Nevada. Bulk density and macroporosity values were generated from soil samples collected in areas of different land use intensities in camps that had been abandoned for approximately 70 years. Results show that significant differences remain in bulk density values between abandoned roads and undisturbed areas in both towns, and that the areas around foundation peripheries are still significantly more compacted in one town. There were no significant differences between land use groups as measured by macroporosity. Estimated soil recovery, based on a …

Stratification Of Habitats For Identifying Habitat Selection By Merriam's Turkeys, Mark A. Rumble, Stanley H. Anderson

Great Basin Naturalist

Habitat selection patterns of Merriam's Turkeys were compared in hierarchical analyses of three levels of habitat stratification. Habitat descriptions in first-level analyses were based on dominant species of vegetation. Habitat descriptions in second-level analyses were based on dominant species of vegetation and overstory canopy cover. Habitat descriptions in third-level analyses were based on dominant species of vegetation, overstory canopy cover, and structural stages (dbh categories). First-level analyses showed turkeys selected for ponderosa pine and selected against meadow habitats. No conclusions could be drawn regarding forest management on habitat selection of turkeys at this level of habitat stratification. Second-level analyses showed …
