U.S. Marine Corps Lance Cpl. Ariel Tolentino, a sensor surveillance operator, conceals two cameras on the ground during an operational check at Camp Lejeune, N.C. The U.S. Army Research Laboratory is developing isotope-powered batteries that could allow unattended ground sensors to continue operating for far greater periods that today’s chemical batteries will allow.

U.S. Army researchers are developing batteries powered by radioisotopes that could last for decades, or longer. The long-lived power sources could lighten the logistics load on the battlefield and energize sensors and communications nodes for extended periods, offering enhanced situational awareness and opening up operational options for warfighters that do not exist today.

Cyberspace has security problems, and the U.S. government is trying to do something about it. The National Strategy for Trusted Identities in Cyberspace (NSTIC) is promoting a plan and taking actions to move citizens beyond usernames and passwords to more powerful methods of authentication. In recent years, massive data theft has occurred in the cyber realm. Even strong passwords are vulnerable to hackers.

A lightweight robot that can leap more than 20 feet horizontally and vertically could be fielded within a year if funding is made available. By enhancing situational awareness during urban combat operations, the robot has the potential to lower casualties both for civilians and for friendly forces fighting their way through a city environment.

The U.S. Army is giving soldiers who have lost limbs a higher quality of life, including allowing some to remain on active duty or to return to combat if they choose. In part because of research conducted through the Army’s Advanced Prosthetics and Human Performance program, individuals who have lost limbs are jumping out of airplanes or commanding troops in combat.

For my February 2010 article, I interviewed members of the Defense Department's Human Spaceflight Payloads Office and Space Test Program about the experiments they help put into space. The projects impressed me, as did the sources' firm belief in the importance of what they do to help warfighters. At the end of our interview, I asked the gentlemen to indulge me on a personal question: "What would you recommend to a child like my son, who wants to grow up to become, as he calls it, 'a space scientist?'"
