Mars Orbitor Curiosity Set For Software Update

Primary tabs

A healthy Curiosity spent Sol 4, its fifth day on Mars, preparing for this weekend's planned "brain transplant"--transitioning to a new version of  flight software on both of Curiosity's redundant main computers.   The new software is better suited for Mars surface operations, such as driving and using Curiosity's robotic arm.

The "brain transplant" will take place during a series of steps beginning this evening and continuing through Aug. 13, 2012.

The new software was uploaded to the rover's memory during the Mars Science Laboratory spacecraft's flight from Earth. Key capabilities in the new software enable full use of Curiosity's powerful robotic arm and drill, and advanced image processing to check for obstacles while driving. This will ultimately allow Curiosity to make longer drives by giving the rover more autonomy to identify and avoid potential hazards and to drive along a safe path that the rover identifies for itself.

The flight team elected to defer further science activities until after the flight software transition is completed.

Several Mastcam color images were downlinked. The mission's science team is busy analyzing images Curiosity has taken of its surroundings, and is discussing features of interest that they will investigate in a few weeks once initial checkouts of the rover and the landing site are completed.

This always scares me when they update software over 200 million miles away. I always think of what could go wrong. I read that the onboard computer or memory is actually about 8 years old. It was designed to stand up to radiation. The old software handled the trip to Mars, and I guess there wasn't room for the software required to actually operate the rover once it was on Mars. Truly amazing. It shows you just how complicated this mission truly is.
