Book excerpt: "Fifty years after the founding of NASA, from 28 to 29 October 2008, the NASA History Division convened a conference whose purpose was a scholarly analysis of NASA's first 50 years. Over two days at NASA Headquarters, historians and policy analysts discussed NASA's role in aeronautics, human spaceflight, exploration, space science, life science, and Earth science, as well as crosscutting themes ranging from space access to international relations in space and NASA's interaction with the public. The speakers were asked to keep in mind the following questions: What are the lessons learned from the first 50 years? What is NASA's role in American culture and in the history of exploration and discovery? What if there had never been a NASA? Based on the past, does NASA have a future? The results of those papers, elaborated and fully referenced, are found in this 50th anniversary volume."--Introduction.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. needs military satellite systems that will continue to function or be replaced with appropriate timing not only during peace but to support military operations throughout plausible important wartime contingencies. The U.S. also needs ways of degrading satellites used to support attacks on our allies or ourselves. In a war with the Soviet Union, space will be no sanctuary but will be an important determinant of the outcome of the war. Space systems can acquire and distribute information critical for the West in defeating a Soviet invasion--about the gathering and onset of attacks, about the location, status and movements of our own and allied forces and of adversary forces and civil society, and about the weather affecting military operations, and much else. In principle, surveillance satellites can provide information about the location and movement of enemy forces over-the-horizon and at great distances, information useful for battle management or to target specific forces as well as for warning about preparations for war. Communications satellites can distribute information over oceans and large land masses that would be essential for keeping our offense and defense forces effectively directed at achieving essential political military goals. A Soviet invasion can benefit by analogous information. And the Soviets, much more than the U.S., have plainly designed their space systems to function in wartime. Soviet satellite systems generally are more proliferated. Their communications satellites, for example, are large in number and are placed in several different and widely separated orbits. (Practically all of our communications satellites are at geosynchronous altitude.) Some Soviet communications satellites are small, cheap and easy to replace. The Soviets have large numbers and many types of space launch vehicles. They also have many types of ICBMs, some mobile as well as fixed.

Book excerpt: This is a report by six US scientists and engineers concerning the current state of the art and projections of future Soviet satellite communications technologies. The panel members are experts in satellite stabilization, spacecraft environments, space power generation, launch systems, spacecraft communications sciences and technologies, onboard processing, ground stations, and other technologies that impact communications. The panel assessed the Soviet ability to support high-data-rate space missions at 128 Mbps by evaluating current and projected Soviet satellite communications technologies. A variety of space missions were considered, including Earth-to-Earth communications via satellites in geostationary or highly elliptical orbits, those missions that require space-to-Earth communications via a direct path and those missions that require space-to-Earth communications via a relay satellite. Soviet satellite communications capability, in most cases, is 10 years behind that of the United States and other industrialized nations. However, based upon an analysis of communications links needed to support these missions using current Soviet capabilities, it is well within the current Soviet technology to support certain space missions outlined above at rates of 128 Mbps or higher, although published literature clearly shows that the Soviet Union has not exceeded 60 Mbps in its current space system. These analyses are necessary but not sufficient to determine mission data rates, and other technologies such as onboard processing and storage could limit the mission data rate well below that which could actually be supported via the communications links. Presently, the Soviet Union appears to be content with data rates in the low-Earth-orbit relay via geostationary mode of 12 Mbps. This limit is a direct result of power amplifier limits, spacecraft antenna size, and the utilization of K{sub u}-band frequencies. 91 refs., 16 figs., 15 tabs.
