Curiosity Finds Conditions Once Suited For Ancient Life On Mars: An analysis of a rock sample collected by Curiosity shows ancient Mars could have supported living microbes. The data indicate the Yellowknife Bay area the rover is exploring was the end of an ancient river system or an intermittently wet lake bed that could have provided chemical energy and other favorable conditions for microbes. The rock is made up of a fine-grained mudstone containing clay minerals, sulfate minerals and other chemicals. This ancient wet environment, unlike some others on Mars, was not harshly oxidizing, acidic or extremely salty.
Mars Rover Team Chooses Not to Drill 'Bonanza King': Evaluation of a pale, flat Martian rock as the potential next drilling target for Curiosity determined that the rock was not stable enough for safe drilling. The rock, called "Bonanza King," moved slightly during the mini-drill activity at an early stage of this test, when the percussion drill impacted the rock a few times to make an indentation.
Curiosity Prepares for Fourth Rock Drilling: The team operating Curiosity has chosen a rock that looks like a pale paving stone as the mission's fourth drilling target, if it passes engineers' evaluation. They call it "Bonanza King."
Two Years and Counting on Red Planet: During its first year of operations, Curiosity fulfilled its major science goal of determining whether Mars ever offered environmental conditions favorable for microbial life. During its second year, Curiosity has been driving toward long-term science destinations on lower slopes of Mount Sharp.
Curiosity Nears Mountain-Base Outcrop: As it approaches the second anniversary of its landing on Mars, Curiosity is also approaching its first close look at bedrock that is part of Mount Sharp, the layered mountain in the middle of Mars' Gale Crater.
Images Show Laser Flash on Martian Rock: Flashes appear on a baseball-size Martian rock in a series of images taken by the Mars Hand Lens Imager (MAHLI) camera on the arm of Curiosity. The flashes occurred while the rover's Chemistry and Camera (ChemCam) instrument fired multiple laser shots to investigate the rock's composition.
Curiosity Marks First Martian Year: Curiosity completed a Martian year - 687 Earth days - on June 24, 2014, having accomplished the mission's main goal of determining whether Mars once offered environmental conditions favorable for microbial life.
Curiosity Wrapping Up Waypoint Work: Portions of powdered rock collected by drilling into a sandstone target last week have been delivered to laboratory instruments inside Curiosity, and the rover will soon drive on toward its long-term destination on a mountain slope.
Curiosity Rover Drills Sandstone Slab on Mars: Portions of rock powder collected by the hammering drill on Curiosity from a slab of Martian sandstone will be delivered to the rover's internal instruments.
"Windjana" Looks Good for Drilling: Curiosity has used several tools to examine the candidate site including a wire-bristle brush - the Dust Removal Tool - to clear away dust from a patch on the rock.
Drill Here?: The team operating Curiosity Mars is telling the rover to use several tools to inspect a sandstone slab being evaluated as a possible drilling target. If this target meets criteria set by engineers and scientists, it could become the mission's third drilled rock, and the first that is not mudstone.

Rocks in the News
Utah Goblin Topplers Sentenced To Probation : Glenn Tuck Taylor and David Benjamin Hall may have to shell out thousands to pay for warning signs telling future visitors to Goblin Valley State Park to leave the rocks alone. The men were sentenced to a year of probation without jail time and payment of restitution after pleading guilty to knocking over an ancient rock formation in the state park.
Ex-Boy Scout Leaders Charged With Felonies: It just took a little push to topple the delicately perched boulder - millions of years in the making - in Utah's Goblin Valley State Park. Then the man who did it laughed, high-fived his son, and flexed his muscles while being cheered on by a fellow Boy Scout leader. He is not likely celebrating now, nor is his friend who videotaped then publicized the episode, after both were charged with third-degree felonies.
Boy Scouts Toss 2 Leaders Who Knocked Over Goblin: A northern Utah Boy Scouts council has announced that former Boy Scout leaders Glenn Taylor and Dave Hall will no longer be allowed to lead scouting troops as a result of their vandalism of Goblin Valley State Park.
Boy Scout Leaders Destroy Ancient Formation In Utah's Goblin Valley: Boy Scout and Church of Jesus Christ of Latter-day Saints youth leaders Dave Hall, Glenn Taylor and Dylan Taylor are potentially facing felony charges for destroying a rock formation nearly 200 million years old. The trio of vandals was adventuring in Utah's Goblin Valley State Park when they decided to film themselves knocking over one of the formations, known as "Goblins."
'Sailing Stones' Mystery of Death Valley Solved: Racetrack Playa is home to an enduring Death Valley mystery. Littered across the surface of this dry lake are hundreds of rocks - some weighing as much as 700 pounds - that seem to have been dragged across the ground, leaving synchronized trails that can stretch for hundreds of meters. The rare combination of events causing the rocks to move is now known.
Exceptionally Well Preserved Insect Fossils From The Rhône Valley Found: Now, for the first time, researchers have found fossil insects in the French equivalent of the Tithonian Konservat-Lagerstätte lithographic limestone - discoveries which include a new species representing the oldest known water treader.
World’s Largest Dinosaur Discovered: The newly discovered dinosaur species Dreadnoughtus schrani makes Tyrannosaurus rex look like a munchkin. The towering behemoth, which stretched a bit longer than a 25-meter swimming pool and as tall as a two-story building, weighed more than seven T. rexes. And the animal was still growing.
What Happens When A Volcano Erupts Under A Glacier?: Nobody will really know the answer to that until Bárðarbunga actually erupts.
Neanderthal 'Hashtag' Carving Found In Cave: The hashtag may be a symbol of modern life, but its origins can be traced back to Neanderthal carvings. Scientists have discovered the first evidence of artwork by this species etched into the walls of a cave in Gibraltar.
Peru's Petrified Forest: Tucked high in the Andes Mountains of northern Peru is a remarkable fossil locality: a 39-million-year-old petrified forest preserved in nearly pristine condition. Since its discovery, scientists and other concerned citizens have been working to study and preserve the spectacular site and its unusual and diverse fossils.
World's Biggest-ever Flying Bird Discovered: Scientists have identified the fossilized remains of an extinct giant bird that could be the biggest flying bird ever found. Pelagornis sandersi was an extremely efficient glider, with long slender 20-24 foot wings that helped it stay aloft despite its enormous size.
Rare Fossil Eggs Reveal How Pterosaurs Lived: The spectacular discovery of three dimensional 120-million year old pterosaur eggs provides a unique insight into the ancient flying reptiles' lifestyle. Until now, only four pterosaur eggs had ever been found, and all were flattened during the process of fossilisation.
Original 'Early Bird' Really Could Fly: Archaeopteryx - considered Earth's oldest-known bird - was completely capable of flying, a new analysis of fossil remains has found. The findings dispel suggestions the creature's feathers were too weak to support flight.
Animals Built Reefs 550 Million Tears Ago: Researchers have discovered that one of the world's oldest reefs - now located on dry land in Namibia - was built almost 550 million years ago by the first animals to have hard shells.
Salt Water On Titan: Scientists analyzing data from NASA's Cassini mission have firm evidence the ocean inside Saturn's largest moon, Titan, might be as salty as Earth's Dead Sea.
Staking a claim: Deep-sea mining nears fruition: Deep sea hydrothermal vent systems contain untapped mineral wealth that would have been beyond any prospector’s wildest dreams just decades ago.
