Moving Forward By Moving Backward
To manage on five out of six wheels, the Spirit rover has found backing up to be more efficient than driving forward. The net result however continues to impress mission scientists as they back their way into the Columbia Hills.
New Martian Meteorite
Weighing nearly two pounds, a black hunk from ancient Mars has been discovered against the white Antarctic backdrop. Following its December 2003 discovery, the nakhlite meteorite is now thought to have crystallized from thick martian lava flows over a billion years ago, then landed on earth around 11 million years ago.
The Big Dig
Preparing to explore the subsurface of Mars involves a new generation of missions, ones that benefit from a natural analogy to burrowing like a mole. The mission concept is referred to as the Mars Mole, which scientists hope to have in prototype stage later this year.
The Human Extreme
Most scientists never think of extremophiles as higher organisms like humans, but deciphering what Greek antiquity considered a noble extreme--the marathon race--suggests that what one organism can survive may not be entirely dependent on the traditional environmental pressures.
