WASHINGTON -- Two prominent aerospace industry organizations are recognizing the contributions of NASA, especially the achievements of the team that landed NASA's Curiosity rover on Mars in August, with coveted awards.
The National Aeronautic Association (NAA) will present its Robert J. Collier Trophy to the Mars Science Laboratory (MSL) Team of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., at an event in Arlington, Va., Thursday night. At an event in Washington on Wednesday, the team received the American Institute of Aeronautics and Astronautics (AIAA) Foundation Award.
AIAA also conferred its highest recognition, the title of honorary fellow, on William Gerstenmaier, NASA's associate administrator for human exploration and operations and presented NASA's Associate Administrator for Science, astronaut John Grunsfeld, with its AIAA National Capitol Section Barry Goldwater Educator Award. AIAA recognized two other NASA employees as fellows: Ray G. Clinton of NASA's Marshall Space Flight Center in Huntsville, Ala., and Laurence D. Leavitt of NASA's Langley Research Center in Hampton, Va.
"It's wonderful to see NASA's people and their accomplishments recognized by the aerospace community," NASA Administrator Charles Bolden said. "In particular, the Curiosity landing was the hardest NASA mission ever attempted in the history of robotic planetary exploration. These prestigious awards are a testament to the dedication and hard work of the entire worldwide team."
The NAA established the Collier Trophy in 1911 and presents it yearly to recognize the greatest achievement in aeronautics or astronautics in America. The AIAA awards recognize the most influential and inspiring individuals in aerospace, whose outstanding contributions merit the highest accolades. Past honorees have included Orville Wright, Neil Armstrong, the team that designed the space shuttle and the astronauts who carried out the first Hubble Space Telescope repair mission in 1993.
The NAA's Collier citation notes the MSL team's "extraordinary achievements of successfully landing Curiosity on Mars, advancing the nation's technological and engineering capabilities, and significantly improving humanity's understanding of ancient Martian habitable environments."
More than 7,000 people in at least 33 U.S. states and 11 other countries have worked on the Mars Science Laboratory mission. Curiosity, the laboratory's centerpiece, carries 10 science instruments to investigate the environmental history inside Gale Crater on Mars. In March, rover scientists announced an analysis of a rock sample collected there shows Mars could have supported living microbes in an ancient freshwater environment. Curiosity's mission is expected to last at least two years.
"The prestigious Collier Trophy is a wonderful recognition for Curiosity, a phenomenal engineering and science achievement that has captured the hearts and minds of children and adults across America and around the globe," said Charles Elachi, director of JPL. "It's an honor to do missions like this one on behalf of NASA and the nation."
Two other teams from JPL that manage NASA spacecraft, the Dawn mission to the asteroid belt and the Voyager mission to interstellar space, were finalists for the 2012 Collier Trophy. JPL designed, developed and assembled the rover and manages its mission for NASA's Science Mission Directorate in Washington.

 NASA Curiosity Rover Team Selects Second Drilling Target on Mars
 PASADENA, Calif. -- The team operating NASA's Curiosity Mars rover on Mars has selected a second target rock for drilling and sampling. The rover will set course to the drilling location in coming days.

This second drilling target, called "Cumberland," lies about nine feet (2.75 meters) west of the rock where Curiosity's drill first touched Martian stone in February. Curiosity took the first rock sample ever collected on Mars from that rock, called "John Klein." The rover found evidence of an ancient environment favorable for microbial life. Both rocks are flat, with pale veins and a bumpy surface. They are embedded in a layer of rock on the floor of a shallow depression called "Yellowknife Bay."

This second drilling is intended to confirm results from the first drilling, which indicated the chemistry of the first powdered sample from John Klein was much less oxidizing than that of a soil sample the rover scooped up before it began drilling.

"We know there is some cross-contamination from the previous sample each time," said Dawn Sumner, a long-term planner for Curiosity's science team at the University of California at Davis. "For the Cumberland sample, we expect to have most of that cross-contamination come from a similar rock, rather than from very different soil."

Although Cumberland and John Klein are very similar, Cumberland appears to have more of the erosion-resistant granules that cause the surface bumps. The bumps are concretions, or clumps of minerals, which formed when water soaked the rock long ago. Analysis of a sample containing more material from these concretions could provide information about the variability within the rock layer that includes both John Klein and Cumberland.

Mission engineers at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., recently finished upgrading Curiosity's operating software following a four-week break. The rover continued monitoring the Martian atmosphere during the break but the team did not send any new commands because Mars and the sun were positioned in such a way the sun could have blocked or corrupted commands sent from Earth.

Curiosity is about nine months into a two-year prime mission since landing inside Gale Crater on Mars. After the second rock drilling in Yellowknife Bay and a few other investigations nearby, the rover will drive toward the base of Mount Sharp, a 3-mile (5-kilometer) tall layered mountain inside the crater.

JPL manages the Mars Science Laboratory Project, of which Curiosity is the centerpiece, for NASA's Science Mission Directorate in Washington.
