“Chances of water on Mars” - feel Scientists
A whole new world for curiosity.

PASADENA, US: The first colour image taken from orbit shows NASA’s rover Curiosity on Mars. This includes details of the layered bedrock on the floor of Gale Crater that the rover is beginning to investigate, where water could be found. Operators of the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter added the colour 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. 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,” said Alfred McEwen, HiRISE Principal Investigator, University of Arizona.

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 5 August 2012, 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. Now we are moving on to a new phase of functional checkouts of the science instruments and preparations for a short test drive,” said Mike Watkins, Curiosity Mission Manager, Jet Propulsion Laboratory, NASA. 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.

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,” said Ashwin Vasavada, Deputy Project Scientist for Curiosity.

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.
