The RAND authors examined developments in international and military affairs drawing little attention today that are expected to be major issues in the ...
These proceedings address benefits and risks of international air and space activities, including how they affect global and national security and interoperability among coalition partners with differing technological capabilities.
The debate over space weaponization is typically cast in simplistic, unidimensional terms, while many participants caricature their opponents as naive pacifists or rabid warmongers. This article redraws the subject more realistically.
Growth in the technical capabilities of commercial and foreign space systems, potential exploitation of space by adversaries, increasing use of commercial space capabilities by U.S. forces, and continuing budget constraints are all ...
Small spacecraft have become popular for a number of reasons, most prominently the needs to reduce overall cost, be built more quickly, and spread mission risks. Despite the risks, however, small spacecraft fulfill important roles in earth science, astrophysics, space physics, and planetary science. NASA's current generation of small spacecraft is capable of impressive levels of performance.
The Global Positioning System (GPS) is a space-based signal providing precise timing, location, and velocity information. Just as any number of receivers can tune into a commercial TV or radio station, there is no limit on the number of people who can use GPS.
