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.

Undressing Vesta: NASA’s Dawn spacecraft is orbiting the asteroid Vesta and sending back images and other data to the delight and amazement of researchers.
Billions of Rocky Planets Orbiting Red Dwarfs In Habitable Zones: A new result from ESO's HARPS planet finder shows that rocky planets not much bigger than Earth are very common in the habitable zones around faint red stars. Researchers estimate there are tens of billions of such planets in the Milky Way galaxy alone, and probably about one hundred in the Sun's immediate neighbourhood.
Titanium Paternity Test Fingers Earth As Moon's Sole Parent: A new chemical analysis of lunar material collected by Apollo astronauts in the 1970s conflicts with the widely held theory that a giant collision between Earth and a Mars-sized object gave birth to the moon 4.5 billion years ago.
Exploding Dinosaur Hypothesis Implodes: The pregnant ichthyosaur female from Holzmaden, Germany that perished 182 million years ago puzzled researchers for quite some time: The skeleton of the extinct marine reptile is almost immaculately preserved and the fossilized bones of the mother animal lie largely in their anatomical position. The bones of the ichthyosaur embryos, however, are a different story.
Crocodilians Bit Harder Than T. Rex: The bite forces of the largest extinct crocodilians exceeded 23,000 pounds, a force two times greater than the mighty Tyrannosaurus rex.
Volcanic 'Plumbing Systems' Exposed: Two new studies into the location and behaviour of magma chambers on Earth's mid-ocean ridge system could bring scientists closer to predicting large eruptions.
Lucy Was Not Alone: The discovery of a remarkably rare partial foot from an ancient primate suggests that more than one kind of human ancestor walked upright in Africa when Lucy's species, Australopithecus afarensis, was alive. The primitive traits in this 3.4-million-year-old partial right foot also show that there was more than one way for early human ancestors to walk upright for at least a million years.
Lucy Lived Among Close Cousins: The Burtele partial foot clearly shows that at 3.4 million years ago, Lucy’s species, which walked upright on two legs, was not the only hominin species living in Ethiopia.
New Hominid Ancestor Grasped At Walking: A 3.4 million-year-old partial fossil foot unearthed in Ethiopia comes from a previously unknown hominid species that deftly climbed trees but walked clumsily.
Life’s Building Blocks Grow Close To Home: In a new study, scientists suggest that complex organic molecules - such as the amino acids that build proteins and the ringed bases that form nucleic acids - grow on the icy dust grains that lived in the infant solar system.
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.
