Microsoft co-founder Paul Allen and aerospace pioneer Burt Rutan are building the world’s biggest plane to help launch cargo and astronauts into space, in the latest of several ventures fueled by technology tycoons clamoring to write America’s next chapter in spaceflight.

Looking through walls is no longer something we read about in comic books or watch in Superman movies. The Massachusetts Institute of Technology's Lincoln Laboratory has presented new radar technology that would allow humans to see through a solid wall.

One afternoon last fall at Fort Benning, Ga., two model-size planes took off, climbed to 800 and 1,000 feet, and began criss-crossing the military base in search of an orange, green and blue tarp. The automated, unpiloted planes worked on their own, with no human guidance, no hand on any control. After 20 minutes, one of the aircraft, carrying a computer that processed images from an onboard camera, zeroed in on the tarp and contacted the second plane, which flew nearby and used its own sensors to examine the colorful object. Then one of the aircraft signaled to an unmanned car on the ground so it could take a final, close-up look. Target confirmed. This successful exercise in autonomous robotics could presage the future of the American way of war: a day when drones hunt, identify and kill the enemy based on calculations made by software, not decisions made by humans. Imagine aerial “Terminators,” minus beefcake and time travel.

NASA's humanoid robot has finally awakened in space. Ground controllers turned Robonaut on Monday for the first time since it was delivered to the International Space Station in February. The test involved sending power to all of Robonaut's systems. The robot was not commanded to move; that will happen next week.
