NASA Mars Curiosity Rover: New Software upgrade completed - Wheel checks

NASA's Mars rover Curiosity captured this 360-degree view using its Navigation Camera (Navcam) after a 17-foot (5.3 meter) drive on 477th Martian day, or sol, of the rover's work on Mars (Dec. 8, 2013). 

This drive brought the mission's total driving distance to 3.86 miles (4.61 kilometers). The rock-studded terrain Curiosity has traversed since October 2013 appears to have accelerated the pace of wear and tear on the rover's wheels. 

Future drives may be charted to cross smoother ground where available.

The team operating NASA's Mars rover Curiosity has completed a software upgrade on the vehicle and is next planning a check of wear and tear on the rover's wheels.

"Curiosity is now operating on version 11 of its flight software," said Jim Erickson of NASA's Jet Propulsion Laboratory, project manager for the NASA Mars Science Laboratory Project, which operates Curiosity.

This is the third upgrade version since Curiosity's landing on Mars16 months ago. Completing the switch from version 10 took about a week.

An earlier switch to version 11 prompted an unintended reboot on Nov. 7 and a return to version 10, but the latest transition went smoothly.

These upgrades allow continued advances in the rover's capabilities.

For example, version 11 brings expanded capability for using the Curiosity's robotic arm while the vehicle is on slopes.

It also improves flexibility for storing information overnight to use in resuming autonomous driving on a second day.

An upcoming activity will be driving to a relatively smooth patch of ground to take a set of images of Curiosity's aluminum wheels, using the Mars Hand Lens Imager (MAHLI) camera at the end of the rover's arm.
