In a technological tour de force, NASA's nuclear-powered Curiosity rover was lowered to the surface of Mars by a rocket-powered flying crane late Sunday to kick off a $2.5 billion mission.
Engineers say NASA's Mars Science Laboratory rover is on track and in good health as it races toward the red planet for a dramatic seven-minute plunge to the surface to kick off a $2.5 billion mission.
At first blush, using a rocket-powered flying crane to lower a $2.5 billion nuclear-powered rover to the surface of Mars seems risky at best. But engineers say it solves a host of daunting challenges.
John Hopkins researchers modify a robot normally used for surgery with the hopes of operating a robotic tanker to refuel satellites in space.
An old NASA satellite is expected to fall back into the atmosphere late this month, resulting in a shower of debris, more than 1,000 pounds of which will hit the ground. But experts say public risk is minimal.
Unlike past Mars missions, Curiosity will be lowered to the ground and set on its wheels by a slowly descending "sky crane" designed to unreel the lander like a lure on a fishing line.
Sun CEO Jonathan Schwartz sheds some light on Sun's plans to become a provider of infrastructure services for the cloud and its JavaFX strategy.
The Pentagon scored a point for missile defense advocates last week, it also left some questions hanging in the air.
The Pentagon quickly pronounced the mission a success, not just in hitting the satellite at all, but also in apparently rupturing its fuel tank.
