Data Format Standards for Civilian Remote Sensing Satellites

Description: This report discusses the earth data—positional, topographic, climatological, meteorological, man–made features, and changes over time in all of these, which are increasingly important to the military. Data from these systems are bought and extensively used by the military and intelligence communities. The need to integrate data from military-unique systems as well only complicates the situation.

Approximating soil loss calculations with satellite data and multivariate regression analyses

Description: Digital satellite remote sensing and Geographic Information Systems (GIS) have been used effectively to determine the Universal Soil Loss Equation (USLE) output for a number of North Texas watersheds. This method involves determining the values of each of the USLE factors and using these factors as information layers within the GIS.

The Satellite Code: A Numerical Satellite Integration Program for the IBM 704

Description: From Introduction: "This report is intended as a handbook for the users of the Satellite code which was developed as a general purpose satellite and space probe program. The components of acceleration, in a three-dimensional rectangular coordinate system, are integrated to produce the velocities and coordinates. These may be transformed into elliptical elements at each time step. The output, therefore, may resemble an integration in the coordinates as well as in the parameters."

Threats to U.S. National Security Interests in Space: Orbital Debris Mitigation and Removal

Description: This report discusses the National Security Space Strategy. After decades of activities in space, Earth's orbit is littered with man-made objects that no longer serve a useful purpose that potentially threaten U.S. national security interests in space, both governmental (military, intelligence, and civil) and commercial. Congress has broadly supported the full-range of these national security interests and has a vested concern in ensuring a strong and continued U.S. presence in space.

Hubble Space Telescope: NASA's Plans for a Servicing Mission

Description: The National Aeronautics and Space Administration (NASA) estimates that without a servicing mission to replace key components, the Hubble Space Telescope will cease scientific operations in 2008. In January 2004, then-NASA Administrator Sean O'Keefe announced that the space shuttle would no longer be used to service Hubble. Hubble supporters criticized this as a result of President Bush's new Vision for Space Exploration; said supporters sought to reverse the decision and proceed with a shuttle servicing mission. In October 2006, NASA approved a shuttle mission to service Hubble. That mission is now scheduled for October 8, 2008.

Commercial newsgathering from space

Description: This technical memorandum concludes that although the technology is available to create a mediasat system, the high cost and current low demand for remotely sensed data will limit media efforts to own and operate a dedicated remote sensing satellite system.

On identifying the specular reflection of sunlight in earth-monitoring satellite data.

Description: Among the background signals commonly seen by Earth-monitoring satellites is the specular reflection of sunlight off of Earth's surface, commonly referred to as a glint. This phenomenon, involving liquid or ice surfaces, can result in the brief, intense illumination of satellite sensors appearing from the satellite perspective to be of terrestrial origin. These glints are important background signals to be able to identify with confidence, particularly in the context of analyzing data from satellites monitoring for transient surface or atmospheric events. Here we describe methods for identifying glints based on the physical processes involved in their production, including spectral fitting and polarization measurements. We then describe a tool that, using the WGS84 spheroidal Earth model, finds the latitude and longitude on Earth where a reflection of this type could be produced, given input Sun and satellite coordinates. This tool enables the user to determine if the surface at the solution latitude and longitude is in fact reflective, thus identifying the sensor response as a true glint or an event requiring further analysis.

Landsat and the Data Continuity Mission

Description: This report discusses the U.S. Landsat Mission, which has collected remotely sensed imagery of the Earth's surface for more than 35 years. The two satellites currently in orbit are operating beyond their designed life and may fail at any time. Most Landsat data is used by federal agencies. Efforts to commercialize Landsat operations have not been successful. This report discusses issues facing Congress regarding funding for new Landsat satellites.

Satellite Surveillance: Domestic Issues

Description: This report provides background on the development of intelligence satellites and identifies the roles various agencies play in their management and use. Issues surrounding the current policy and proposed changes are discussed, including the findings of an Independent Study Group (ISG) with respect to the increased sharing of satellite intelligence data. There follows a discussion of legal considerations, including whether satellite reconnaissance might constitute a "search" within the meaning of the Fourth Amendment; an overview of statutory authorities, as well as restrictions that might apply; and a brief description of executive branch authorities and Department of Defense directives that might apply. The report concludes by suggesting policy issues Congress may consider as it deliberates the potential advantages and pitfalls that may be encountered in expanding the role of satellite intelligence for homeland security purposes.

China's Space Program: Options for U.S.-China Cooperation

Description: China has a determined, yet still modest, program of civilian space activities planned for the next decade. The potential for U.S.-China cooperation in space -- an issue of interest to Congress -- has become more controversial since the January 2007 Chinese anti-satellite test. Some argue that Chinese capabilities now threaten U.S. space assets in low earth orbit. Others stress the need to expand dialogue with China. This report outlines recent activities and future plans in China's civilian space sector. It also discusses benefits and trade-offs of possible U.S.-China collaboration in space, as well as several options to improve space relations, including information exchange, policy dialogue, and joint activities.

Systematic evaluation of satellite remote sensing for identifying uranium mines and mills.

Description: In this report, we systematically evaluate the ability of current-generation, satellite-based spectroscopic sensors to distinguish uranium mines and mills from other mineral mining and milling operations. We perform this systematic evaluation by (1) outlining the remote, spectroscopic signal generation process, (2) documenting the capabilities of current commercial satellite systems, (3) systematically comparing the uranium mining and milling process to other mineral mining and milling operations, and (4) identifying the most promising observables associated with uranium mining and milling that can be identified using satellite remote sensing. The Ranger uranium mine and mill in Australia serves as a case study where we apply and test the techniques developed in this systematic analysis. Based on literature research of mineral mining and milling practices, we develop a decision tree which utilizes the information contained in one or more observables to determine whether uranium is possibly being mined and/or milled at a given site. Promising observables associated with uranium mining and milling at the Ranger site included in the decision tree are uranium ore, sulfur, the uranium pregnant leach liquor, ammonia, and uranyl compounds and sulfate ion disposed of in the tailings pond. Based on the size, concentration, and spectral characteristics of these promising observables, we then determine whether these observables can be identified using current commercial satellite systems, namely Hyperion, ASTER, and Quickbird. We conclude that the only promising observables at Ranger that can be uniquely identified using a current commercial satellite system (notably Hyperion) are magnesium chlorite in the open pit mine and the sulfur stockpile. Based on the identified magnesium chlorite and sulfur observables, the decision tree narrows the possible mineral candidates at Ranger to uranium, copper, zinc, manganese, vanadium, the rare earths, and phosphorus, all of which are milled using sulfuric acid leaching.
