A combination of faster computing capabilities, lower cost storage and improved software is opening new markets for commercial satellite imagery in the 1-meter and, in the future, 0.5-meter resolution range. Although these images were once reserved for U.S. government and military uses, today a wide range of organizations is purchasing them to support their missions. From monitoring activity in other countries and creating accurate simulation models to mapping underwater environments, pictures taken from space have become a valuable tool and have ushered the world into what some have termed the age of transparency.

Fast, agile units employing advanced sensors and situational awareness suites will soon become the U.S. Army's vanguard rapid deployment forces. Currently mustering and training at Fort Lewis, Washington, these interim brigade combat teams will rely on a variety of wireless communication and information technologies to detect, outmaneuver and engage more heavily armed opponents.

The U.S. Space Command is spearheading the Department of Defense's efforts to protect military communications from computer network threats. By shifting its network operations emphasis from exclusively defensive to a more offensive stance, USSPACECOM is seeking to ensure the integrity of coalition operations.

Sharon Berry argues that meeting the emerging threat to U.S. space resources "may require instilling commercial business practices in military intelligence organizations, consolidating space system activities under a single Defense Department umbrella, and increasing funding to provide the necessary resources for keeping pace with new technologies."

Military strategists are envisioning future conflicts where U.S. forces execute complex maneuvers on the basis of high-speed data flowing to vehicles and even individuals from unattended sensors and unmanned aerial vehicles.

The U.S. Army is pushing to ensure that the people in charge of the latest tools in warfare are up to date in defending its information and computer networks. Personnel who are key to the service's transformation and its move to digitizing the force are being trained to install, configure, operate and maintain the latest communications systems and are learning to identify evolving threats to these systems.

By mimicking the natural response of living tissue to injury, cross-departmental researchers at the University of Illinois at Urbana-Champaign have developed a polymeric material that heals itself when damaged. Cracks can be precursors to structural failure, and the ability to treat weakened regions will result in longer-lasting materials used in a variety of applications from microelectronics to aerospace.

Researchers are testing a prototype computer interface that allows users to interact with a virtual reality world through brain impulses. If successful, this proof-of-concept device could greatly increase the mobility and independence of people who are paralyzed or have similar conditions.

Scientists at Sandia National Laboratories, Albuquerque, New Mexico, are conducting ground-breaking research into super-small structures that has led to prototype devices such as ultraminiaturized chemical sensors and analyzers, tiny medical devices, super-strong alloys, and catalysts for destroying hazardous materials.

The U.S. Defense Department is turning to a family of software agents that locate, recognize and speed the delivery of critical information to where it is needed most on the battlefield. When minutes and seconds are precious commodities to a warfighter, software transfer agents help manage and expedite the dissemination of badly needed information. These robot-like software tools help leverage the power of the information age.
