Martian Life's Last Stand in the Trenches? "Scientists have found water-bearing deposits on Mars that are out of step with what was happening elsewhere on the planet, raising the prospect that the sites could have hosted Martian life's last stand."

NASA May Have Discovered Flowing Water on Mars Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars' southern hemisphere.

On October 9th, NASA spacecraft will run into the moon, and on purpose. The
Lunar Crater Observation and Sensing Satellite (
LCROSS) and its rocket's
Centaur upper stage will impact the moon, with the goal of sending some of the (possibly present) ice above the lunar surface. Once out of the eternal shade of the moon's south pole, sunlight will break the ice up into H+ and OH- molecules, which can be detected by the
Lunar Reconnaissance Orbiter (
LRO). The
initial impact site was the crater Cabeus A, but the target was
later changed to Cabeus (proper), selected for highest hydrogen concentrations with the greatest level of certainty, and for the high-contrast back drop to detect ejecta and vapor measurements. NASA has provided
guides for amateur observations of the impact,
a facebook group, and
a Twitter feed so you don't miss the moment.

"
We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or
TEGA. "We've seen evidence for this water ice before in observations by the Mars Odyssey orbiter and in disappearing chunks observed by Phoenix
last month, but this is the first time Martian water has been touched and tasted."

Scientists have discovered a planet composed of
scorching hot ice. Originally thought to be a gas giant due to its mass, its actually only four times the size of Earth and most likely composed of exotic forms of ice, such as
Ice VII and Ice X with s surface temperature of 300° C.
