Curiosity rover begins vaporizing Mars, one rock at a time - Christian Science Monitor

Curiosity's Chemical and Camera instrument, or ChemCam, fires a laser pulses that last just five one-billionths of a second but deliver more than a million watts of power, enough to turn solid rock into an ionized plasma. A trio of spectrometers in the tool then studies the sparks from the laser fire on 6,144 different wavelengths of ultraviolet, visible and infrared light to determine the composition of the vaporized rock.

NASA 'itching to move' on Mars as it charts course for Curiosity

The team identified half a dozen potential paths through buttes and mesas that are reminiscent of the southwestern United States. Vasavada estimated it'll take a year to make the trip to the mountain driving about the length of a football field a day. Along the way, the six-wheel rover will make pit stops to study interesting rocks and scoop up soil.<br />http://www.foxnews.com/scitech/2012/08/14/nasa-itching-to-move-on-mars-as-it-charts-course-for-curiosity/

I'm fairly new to geology, and so I wonder if the floating material is still referred to as &quot;pillows&quot; of basalt usually evidenced in under water volcanic activities?<br />http://www.thehindu.com/sci-tech/science/article3757605.ece?homepage%3Dtrue

Flat-Faced Early Humans Confirmed—Lived Among Other Human Species - National Geographic

Not an aberrant specimen, the study makes clear, but a different species from the early Homo varieties previously known to have inhabited Turkana: Homo habilis ("handy man"), the presumed tool user conventionally seen as the earliest known Homo species, and Homo erectus, the "upright man" believed to be a direct ancestor of our own species (time line of human evolution).Consisting of a face, a complete lower jaw, and part of a second jaw, the new fossils were found east of Kenya's Lake Turkana between 2007 and 2009. The products of a 40-year search, they provide the needed evidence to confirm that a disputed skull found in 1972 does in fact represent a new species, the team says.<br />http://news.nationalgeographic.com/news/2012/08/120808-human-evolution-fossils-homo-nature-science-meave-leakey-flat/
