The concept of solar panels beaming down energy from space has long been pondered—and long been dismissed as too costly and impractical. But in Japan the seemingly far-fetched scheme has received renewed attention amid the current global energy crisis..

NASA's Opportunity Mars rover is getting an eyeful, wheeling itself ever closer to a cliff wall that's part of the huge Victoria Crater. A camera campaign is underway, with early imagery producing anticipation within the rover science team back on Earth.

U.S. and British scientists say they have developed a method using ultraviolet light that could identify any organic material present in the soil of Mars.

The odds that a potentially devastating space rock will hit Earth this century may be as high as one in 10. So why isn't NASA trying harder to prevent catastrophe?

The thought of the forces at play in the solar system makes for a thrilling — even chilling — reminder that it was a very dangerous place at the start.

The Phoenix lander's first taste test of soil near Mars' north pole reveals a briny environment similar to what can be found in backyards on Earth, scientists said Thursday. The finding raises hope that the Martian arctic plains could have conditions fav

Some Martian dirt has the same basic chemistry as garden soil, a new analysis from the Phoenix lander suggests. The find widens the range of organisms that might be able to live on Mars.
