[NASA] 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."

sooo instead of just including all of the tested, working, software to begin with, let's wait and send the entire version of mission critical code in phases through space.
seems more reasonable than sending just a little patch.

come on NASA...

I was thinking the same thing. Hopefully they have a backup "BIOS" or whatever they are flashing it onto. tongue.gif

apparently there is a backup computer. my guess is they will do them one at a time
but really couldn't they have strapped a usb drive on? lol

NASA probably has dual "BIOS"es or whatever they are on both. They are very cautious.
