Winter Means Less Power for Solar Panels

Opportunity is ascending 'Solander Point' at the rim of 'Endeavour Crater.' The rover is maintaining favorable northerly tilts for improved energy production.

Opportunity is experiencing the power constraints of the winter season. On Sol 3489 (Nov. 16, 2013), the planned drive had to be shortened considerably owing to the constraint of the expected state of charge of the rover battery.

As such, the rover only turned to face the future destination and bumped 4 inches (10 centimeters).

Panoramic Camera (Pancam) and Navigation Camera (Navcam) images were taken of the near destination. On Sol 3492 (Nov. 19, 2013), the rover bumped forward about 11 feet (3.5 meters) to approach the target outcrop, called 'Moreton Island.'

As of Sol 3494 (Nov. 21, 2013), the solar array energy production was 302 watt-hours with an atmospheric opacity (Tau) of 0.668 and a solar array dust factor of 0.498.

Total odometry is 24.01 miles (38.65 kilometers).

Curiosity Out of Safe Mode
Pasadena CA (JPL) Nov 13, 2013
NASA's Mars Science Laboratory Project received confirmation from Mars Sunday (Nov. 10) that the Curiosity rover has successfully transitioned back into nominal surface operations mode. Curiosity had been in safe mode since Nov. 7, when an unexpected software reboot (also known as a warm reset) occurred during a communications pass with the Mars Reconnaissance Orbiter.
