This NASA image from Mars Curiosity's Mast Camera taken on September 22, 2012 and released October 11, 2012 shows where NASA's Mars Curiosity rover aimed two different instruments to study a rock known as ''Jake Matijevic.'' The red dots are where the Chemistry and Camera (ChemCam) instrument zapped it with its laser on September 21, 2012 and September 24, 2012, which were the 45th and 48th sol, or Martian day of operations. The circular black and white images were taken by ChemCam to look for the pits produced by the laser. The purple circles indicate where the Alpha Particle X-ray Spectrometer trained its view.

CAPE CANAVERAL, Florida (Reuters) - When scientists selected a rock to test the Mars rover Curiosity's laser, they expected it to contain the same minerals as rocks found elsewhere on the Red Planet, but learned instead it was more similar to a rock found on Earth.
The rock was chemically more akin to an unusual type of rock found on oceanic islands like Hawaii and St. Helena, as well as in continental rift zones like the Rio Grande, which extends from Colorado to Chihuahua, Mexico.
"It was a bit of a surprise, what we found with this rock," Curiosity scientist Ralf Gellert of the University of Guelph in Ontario, Canada, told reporters on a conference call Thursday.
"It's igneous," Gellert said, referring to rock formed from molten material. "But it seems to be a new kind of rock type that we encountered on Mars."
Curiosity arrived on Mars two months ago to learn if the most Earth-like planet in the solar system was suitable for microbial life.
Last month, Curiosity's laser was used to zap the football-sized rock and the rover analyzed the pulverized material, as well as tiny pits left behind, to determine its chemical composition.
Scientists found the rock lacks magnesium and iron - elements found in igneous rock examined by previous Mars rovers Spirit and Opportunity.
The rock, named after a Jet Propulsion Laboratory rover engineer, Jake Matijevic, who died shortly after Curiosity's landing, was also rich in feldspar-like minerals, which provided clues about the rock's history.
"The way in which this type of rock forms ... is like how applejack liquor was made," geologist Edward Stolper, with the California Institute of Technology in Pasadena, told reporters.
In colonial times, hard apple cider was put into big barrels and in the winter the liquid would partly freeze. "You'd crystallize out ice and you'd make more and more and more concentrated apple-flavored liquor," Stolper said.
Magma inside a planet can undergo a similar process.
"You melt the interior and it comes to the surface and, just like the applejack, when you cool it, it crystallizes," Stolper said, adding that it takes very particular conditions on Earth to produce this type of magma.
The rover meanwhile has moved on to testing and cleaning of its soil scoop. Eventually, scientists want to funnel soil samples to Curiosity's onboard laboratory for more extensive chemical analysis.
The rover is part way to its first science target, an area known as Glenelg, which has three different types of rock intersecting.
The car-sized Curiosity rover landed inside a giant impact basin called Gale Crater, located near the Martian equator, for a two-year, $ 2.5 billion astrobiology mission, NASA's first since the 1970s-era Viking probes.

Question by David H: Looking for a scene from the movie Walk The Line "I aint never had to drink this yelllow water"? This line came about 10 seconds before Joaquin Phoenix sang the song "Cocaine Blues" which I did find on You Tube - but I'm looking for the scene where he salms the glass of water on the floor right before he sings the song. You Tube does NOT have the capability to ask questions on that site. So I'm asking here on Yahoo Answers. Can anyone help me out? Best answer for Looking for a scene from the movie Walk The Line "I aint never had to drink this yelllow water"?:
Answer by Davis
Oh boy, I LOVE that movie, http://www.movieweb.com/movie/walk-the-line/HUFelLGKtY5jJH is the site i found it on, hope this helps! :)
