PASADENA, Calif. -- The scientists and engineers of NASA's Curiosity rover mission have selected the first driving destination for their one-ton, six-wheeled mobile Mars laboratory. The target area, named Glenelg, is a natural intersection of three kinds of terrain. The choice was described by Curiosity Project Scientist John Grotzinger of the California Institute of Technology during a media teleconference on Aug. 17.

"With such a great landing spot in Gale Crater, we literally had every degree of the compass to choose from for our first drive," Grotzinger said. "We had a bunch of strong contenders. It is the kind of dilemma planetary scientists dream of, but you can only go one place for the first drilling for a rock sample on Mars. That first drilling will be a huge moment in the history of Mars exploration."

The trek to Glenelg will send the rover 1,300 feet (400 meters) east-southeast of its landing site. One of the three types of terrain intersecting at Glenelg is layered bedrock, which is attractive as the first drilling target.

"We're about ready to load our new destination into our GPS and head out onto the open road," Grotzinger said. "Our challenge is there is no GPS on Mars, so we have a roomful of rover-driver engineers providing our turn-by-turn navigation for us."

Prior to the rover's trip to Glenelg, the team in charge of Curiosity's Chemistry and Camera instrument, or ChemCam, is planning to give their mast-mounted, rock-zapping laser and telescope combination a thorough checkout. On Saturday night, Aug. 18, ChemCam is expected to "zap" its first rock in the name of planetary science. It will be the first time such a powerful laser has been used on the surface of another world.

"Rock N165 looks like your typical Mars rock, about three inches wide. It's about 10 feet away," said Roger Wiens, principal investigator of the ChemCam instrument from the Los Alamos National Laboratory in New Mexico. "We are going to hit it with 14 millijoules of energy 30 times in 10 seconds. It is not only going to be an excellent test of our system, it should be pretty cool too."

Mission engineers are devoting more time to planning the first roll of Curiosity. In the coming days, the rover will exercise each of its four steerable (front and back) wheels, turning each of them side-to-side before ending up with each wheel pointing straight ahead. On a later day, the rover will drive forward about one rover-length (10 feet, or 3 meters), turn 90 degrees, and then kick into reverse for about 7 feet (2 meters).

"There will be a lot of important firsts that will be taking place for Curiosity over the next few weeks, but the first motion of its wheels, the first time our roving laboratory on Mars does some actual roving, that will be something special," said Michael Watkins, mission manager for Curiosity from the Jet Propulsion Laboratory in Pasadena, Calif.

The Mars Science Laboratory spacecraft delivered Curiosity to its target area on Mars at 10:31:45 p.m. PDT on Aug. 5 (1:31:45 a.m. EDT on Aug. 6), which included the 13.8 minutes needed for confirmation of the touchdown to be radioed to Earth at the speed of light.

The audio and visuals of the teleconference are archived and available for viewing at: http://www.ustream.tv/nasajpl.

The mission is managed by JPL for NASA's Science Mission Directorate in Washington. The rover was designed, developed and assembled at JPL, a division of Caltech. ChemCam was provided by Los Alamos National Laboratory. France provided ChemCam's laser and telescope.

Orbiter Views NASA's New Mars Rover in Color

The full version of this story with accompanying images is at:
http://www.jpl.nasa.gov/news/news.cfm?release=2012-243&cid=release_2012-243

PASADENA, Calif. -- The first color image taken from orbit showing NASA's rover Curiosity on
Mars includes details of the layered bedrock on the floor of Gale Crater that the rover is beginning to
investigate.

Operators of the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars
Reconnaissance Orbiter added the color view to earlier observations of Curiosity descending on its
parachute, and one day after landing.

"The rover appears as double bright spot plus shadows from this perspective, looking at its shadowed
side, set in the middle of the blast pattern from the descent stage," said HiRISE Principal Investigator
Alfred McEwen, of the University of Arizona, Tucson. "This image was acquired from an angle
looking 30 degrees westward of straight down. We plan to get one in a few days looking more
directly down, showing the rover in more detail and completing a stereo pair."

Meanwhile, Curiosity has finished a four-day process transitioning both of its redundant main
computers to flight software for driving and using tools on the rover's arm. During the latter part of
the Mars Science Laboratory spacecraft's 36-week flight to Mars and its complicated descent to
deliver Curiosity to the Martian surface on Aug. 5, PDT (Aug. 6, EDT and Universal Time), the
rover's computers used a version of flight software with many capabilities no longer needed. The new
version expands capabilities for work the rover will do now that it is on Mars.

"We have successfully completed the brain transplant," said Curiosity Mission Manager Mike
Watkins of NASA's Jet Propulsion Laboratory, Pasadena, Calif. "Now we are moving on to a new
phase of functional checkouts of the science instruments and preparations for a short test drive."

The first drive, possibly within a week or so, will likely include short forward and reverse segments
and a turn. Curiosity has a separate drive motor on each of its six wheels and steering motors on the
four corner wheels. Preparation and testing of the motor controllers will precede the first drive.

After the test drive, the planning schedule has an "intermission" before a second testing phase
focused on use of the rover's robotic arm. For the intermission, the 400-member science team will
have the opportunity to pick a location for Curiosity to drive to before the arm-testing weeks.

"It's fair to say that the scientists, not to mention the rover drivers, are itching to move," said JPL's
Ashwin Vasavada, deputy project scientist for Curiosity.

Researchers have been examining images from Curiosity's cameras and HiRISE to identify potential
targets to investigate near the rover and on the visible slope of the nearby three-mile-high mound
informally named Mount Sharp.

"The science and operations teams are evaluating several potential routes that would take us to Mount
Sharp, with perhaps a few waypoints to inspect some of the different terrains we've identified as we
map the landing area," Vasavada said. "As we have reported many times before, it's going to take us a
good part of our first year to make it to the layered sediments on Mount Sharp."

During a prime mission of nearly two years, researchers will use Curiosity to investigate whether the
selected area of Mars has ever offered chemical ingredients for life and other environmental
conditions favorable for supporting microbial life. Curiosity carries 10 science instruments with a
total mass 15 times as large as the science payloads on NASA's Mars rovers Spirit and Opportunity.

To handle this science toolkit, Curiosity is twice as long and five times as heavy as Spirit or
Opportunity. The landing site inside Gale Crater places the rover within driving distance of layers of
Mount Sharp. Observations from orbit have identified clay and sulfate minerals in the lower layers,
indicating a wet history.

JPL, a division of the California Institute of Technology, in Pasadena, manages the Mars Science
Laboratory and Mars Reconnaissance Orbiter missions for NASA's Science Mission Directorate,
Washington. JPL designed and built Curiosity. HiRISE is operated by the University of Arizona in
Tucson. The instrument was built by Ball Aerospace & Technologies Corp. in Boulder, Colo.
Lockheed Martin Space Systems in Denver built the orbiter.

NASA Curiosity Mars Rover Installing Smarts for Driving

PASADENA, Calif. -- NASA's Mars rover Curiosity will spend its first weekend on Mars
transitioning to software better suited for tasks ahead, such as driving and using its strong robotic
arm.

The rover's "brain transplant," which will occur during a series of steps Aug. 10 through Aug. 13, will
install a new version of software on both of the rover's redundant main computers. This software for
Mars surface operations was uploaded to the rover's memory during the Mars Science Laboratory
spacecraft's flight from Earth.

"We designed the mission from the start to be able to upgrade the software as needed for different
phases of the mission," said Ben Cichy of NASA's Jet Propulsion Laboratory in Pasadena, Calif.,
chief software engineer for the Mars Science Laboratory mission. "The flight software version
Curiosity currently is using was really focused on landing the vehicle. It includes many capabilities
we just don't need any more. It gives us basic capabilities for operating the rover on the surface, but
we have planned all along to switch over after landing to a version of flight software that is really
optimized for surface operations."

A key capability in the new version is image processing to check for obstacles. This allows for longer
drives by giving the rover more autonomy to identify and avoid potential hazards and drive along a
safe path the rover identifies for itself. Other new capabilities facilitate use of the tools at the end of
the rover's robotic arm.

While Curiosity is completing the software transition, the mission's science team is continuing to
analyze images the rover has taken of its surroundings inside Gale Crater. Researchers are discussing
which features in the scene to investigate after a few weeks of initial checkouts and observations to
assess equipment on the rover and characteristics of the landing site.

The Mars Science Laboratory spacecraft delivered Curiosity to its target area on Mars at 10:31:45
p.m. PDT on Aug. 5 (1:31:45 a.m. EDT on Aug. 6), which includes the 13.8 minutes needed for
confirmation of the touchdown to be radioed to Earth at the speed of light.

Curiosity carries 10 science instruments with a total mass 15 times as large as the science payloads on
NASA's Mars rovers Spirit and Opportunity. Some of the tools, such as a laser-firing instrument for
checking rocks' elemental composition from a distance, are the first of their kind on Mars. Curiosity
will use a drill and scoop, which are located at the end of its robotic arm, to gather soil and powdered
samples of rock interiors, then sieve and parcel out these samples into the rover's analytical
laboratory instruments.

To handle this science toolkit, Curiosity is twice as long and five times as heavy as Spirit or
Opportunity. The Gale Crater landing site at 4.59 degrees south, 137.44 degrees east, places the rover
within driving distance of layers of the crater's interior mountain. Observations from orbit have
identified clay and sulfate minerals in the lower layers, indicating a wet history.

Mars Science Laboratory is a project of NASA's Science Mission Directorate. The mission is
managed by JPL. Curiosity was designed, developed and assembled at JPL, a division of the
California Institute of Technology in Pasadena.
