Martian Meteorite ALH84001 Harbinger of Extraterrestrial Life
Check out Bob's Martian Touchdown - A Rockhound's Cosmic Encounter with Three Extraterrestrials

Powerful new twin NASA Mars rovers, Spirit and Opportunity, have successfully landed and deployed on different regions of the Red Planet. With far greater mobility than the 1997 Pathfinder rover, these robotic explorers may trek as much as 40 meters across the surface in a day. Each rover carries a sophisticated set of instruments search for evidence about whether past environments at selected sites were wet enough to be hospitable to life. Rocks and soils will be analyzed with a set of five geology instruments on each rover, and a special tool called the rock abrasion tool, or "RAT", will be used to expose fresh rock surfaces for study.

Arriving at Mars in August 2012, the Mars Science Laboratory will carry the biggest, most advanced suite of instruments for scientific studies ever sent to the Martian surface.

The Curiosity rover will analyze dozens of samples scooped from the soil and drilled from rocks. Curiosity's onboard laboratory will study rocks, soils, and the local geologic setting in order to detect chemical building blocks of life on Mars and will assess what the martian environment was like in the past.

Curiosity Rover On Course: NASA's Mars Science Laboratory spacecraft successfully refined its flight path on January 11 with the biggest maneuver planned for the mission's journey between Earth and Mars. The mission's second trajectory correction maneuver, expected to be about one-sixth the magnitude of this first one, is scheduled for March 26.
Curiosity Rover Already Performing Research in Space: NASA's Curiosity rover has begun monitoring space radiation during its 8-month voyage from Earth to Mars, using its Radiation Assessment Detector (RAD) instrument. The research will aid in planning for future human missions to the Red Planet.
MSL Trajectory Correction Maneuver Slated for January 11: An engine firing on January 11 will be the biggest maneuver that NASA's Mars Science Laboratory spacecraft will perform on its flight between Earth and Mars. The initial trajectory resulting from the mission's November 2011 launch intentionally misses Mars to prevent the unsterilized upper stage of the launch vehicle from hitting Mars.
Mars or Bust: America's next Mars explorer is now cruising through deep space on a mission that could bring mankind within one small step of proving life exists somewhere else in the universe.
Geometry Drives Selection Date For 2011 Mars Launch: Continuing analysis of the geometry and communications options for the arrival at Mars have led planners for the Mars Science Laboratory, or Curiosity, to choose an Earth-to-Mars trajectory that schedules launch between Nov. 25 and Dec. 18, 2011.
NASA Announces Landing Site For The Curiosity Rover: NASA's next Mars rover will land at the foot of a layered mountain inside the planet’s Gale Crater.
Site List Narrows For NASA's Next Mars Landing: Four intriguing places on Mars have risen to the final round as NASA selects a landing site for its next Mars mission, the Mars Science Laboratory.

Survey Suggests Billions Of Planets In Galaxy: A new study suggests each star in the Milky Way galaxy is most likely orbited by a planet - and there's a good chance that planet is closer in size to Earth, than to Jupiter.
Setting Off A Supervolcano: Supervolcanoes are one of nature’s most destructive forces, but given that there are no recorded observations of super-eruptions - the last occurred 74,000 years ago in Indonesia - scientists don’t fully understand how they work.
Moon-Walk Mineral Discovered In Western Australia: Tranquillityite - the last mineral thought to have been unique to the Moon, has been discovered in the remote Pilbara region of Western Australia.
Calibrating A Rock Clock: New research will improve the accuracy of estimates of the time of geological events. The work centres on the calibration of one of the world's slowest clocks, known as the 'argon-argon clock'.
Prehistoric Predators With Supersized Teeth Had Beefier Arm Bones: The toothiest prehistoric predators also had beefier arm bones. Fossil studies reveal this killer combination arose repeatedly in different saber-toothed predators over time, presumably because it gave them an advantage when catching and killing prey.
'Lost World' Discovered Around Antarctic Vents: Communities of species previously unknown to science have been discovered on the seafloor near Antarctica, clustered in the hot, dark environment surrounding hydrothermal vents.
How Did Insects Get Their Hearing?: A new study of 50 million year-old cricket and katydid fossils - sporting some of the best preserved fossil insect ears described to date - help trace the evolution of the insect ear.
Afghanistan's Mineral Resources Laid Bare: Each donning about 10 kilograms of protective gear, including helmets and Kevlar, scientists trudged up the rugged, rocky volcanic terrain of southern Afghanistan, slowing now and then to catch an extra breath of thin air. Some carried rock hammers. Others carried guns.
Vertebrate Evolution Is Head First: By analyzing the physical features of fossil fish that diversified around the time of two separate extinction events, scientists found that head features diversified before body shapes and types.
New Theory Emerges For Origins Of Amphibians: A small fish crawling on stumpy limbs from a shrinking desert pond is an icon of can-do spirit, emblematic of a leading theory for the evolutionary transition between fish and amphibians. However, this theorized image of such a drastic adaptation to changing environmental conditions may be evolving into a new picture.
100 Years Of Continental Drift Theory: 100 years ago Alfred Wegener presented his theory of continental drift to the public for the first time. The classical concept of tectonics as a quasi mechanical process of the movement and collision of rigid plates is now in disarray.
Strange Crystals Reveal Rock To Be Ancient Meteorite: Rather than a simple ratio of, say, 2:1, the ratio of atoms in a quasicrystal is based on an irrational number, such as the square root of 2:1... Any symmetry thought to be forbidden is possible for quasicrystals.
Volcanoes Slide Silently To Their Death: One of the largest trenches in the Earth's crust is slowly consuming undersea volcanoes, and to the surprise of geologists, it appears to lessen the risk of earthquakes.
Second Earth Found?: NASA's Kepler space telescope has confirmed its first planet in the "habitable zone," the region where liquid water could exist on a planet's surface. The newly confirmed planet, Kepler-22b, is the smallest yet found to orbit in the middle of the habitable zone of a star similar to our sun.
Fly-by Reveals Asteroid Lutetia's Primitive Side: 75-mile long Lutetia is believed to be a planetesimal - a fragment of the material that clumped together to make the planets at the birth of the solar system nearly four billion years ago.
Massive Rift Portends Antarctic Berg: Researchers flying over West Antarctica have spotted an actively growing rift that they expect will spawn an iceberg about 10 times the size of Manhattan.
Return Of The Dust Bowl: Over the next two or three decades, the American West could transition to an environment that may make the 1930s Dust Bowl seem mild and brief.
Where Coal Is King In China: Inner Mongolia has become the center of the coal industry in China - the nation that burns the most coal and, as a result, emits the most greenhouse gases in the world.
