Curiosity beams back strong, clear data from ℠scour´ area on Martian surface Members of the Mars Science Laboratory Curiosity rover ChemCam team, including Los Alamos National Laboratory scientists, squeezed in a little extra target practice after zapping the first fist-sized rock that was placed in the laser´s crosshairs last weekend. Much to the delight of the scientific team, the laser instrument has fired nearly 500 shots so far that have produced strong, clear data...

Genesis mission yields solar isotopic composition despite hard landing Two papers in this week's issue of Science report the first oxygen and nitrogen isotopic measurements of the Sun, demonstrating that they are very different from the same elements on Earth. These results were the top two priorities of NASA's Genesis mission, which was the first spacecraft to return from beyond the Moon, crashing in the Utah desert in 2004 after its parachute failed to deploy during re-entry. Most of the...

A rock-zapping laser instrument on NASA's next Mars rover has roots in a demonstration that Roger Wiens saw 13 years ago in a colleague's room at Los Alamos National Laboratory in New Mexico. The Chemistry and Camera (ChemCam) instrument on the rover Curiosity can hit rocks with a laser powerful enough to excite a pinhead-size spot into a glowing, ionized gas. ChemCam then observes the flash through a telescope and analyzes the spectrum of light to identify the chemical elements in the...

LOS ALAMOS, N.M. (AP) -- A laser developed by a Los Alamos National Laboratory scientist will be aboard the Mars Science Laboratory to be launched to the red planet in 2009. Roger Wiens said his "ChemCam" will can blast Martian rocks with a laser beam to determine what they are made of. The mission planned by the National Aeronautics and Space Administration is planned as a followup to successful Mars Rovers, two robots now rolling across Mars' surface. The Mars lab is to arrive at its...
