JPL has some limited information about the Mars rover electronics and the
VME bus: http://marsrovers.jpl.nasa.gov/missi...er_brains.html What kind of CPU and O/S are the rovers using (or do I really want to know)? JJ Robinson II Houston, TX **************** * JOKE * **************** * SERIOUS * **************** * SARCASTIC * **************** * OTHER? * **************** |

The chip itself is a RAD6000, a hardened variant of the Power-PC architectu http://mars.tv/mer/spacecraft.html VME bus based processor card built by BAE, O/S is VxWorks: http://www.washingtontechnology.com/...e/21333-1.html And now that I've googled around a little, there's even a HowStuffWorks page with a surprising amount of information: http://howstuffworks.lycoszone.com/mars-rover4.htm |

Uhh...i heard something about extensive use of JAVA. I just hope it
wasn't in rover itself. It's nice for rebootable web-based systems but i can't stand the tought of bloated, buggy code running inside the poor rover. Somehow, I'm afraid rover "bluescreened" after bloatware choked on something that was impossible to account for. Let's hope they can "reboot" the thing from EPROM and start again... hrtbreak wrote: JPL has some limited information about the Mars rover electronics and the VME bus: http://marsrovers.jpl.nasa.gov/missi...er_brains.html What kind of CPU and O/S are the rovers using (or do I really want to know)?

Unfortunately the info posted really is targeted towards high school kids
and the language used is not up to the mark. Why are such frilly words like "brain" used to describe the electronics. I too wish they had more details in straight forward eningeering language.

Disregard this answer; I've been told on Deep Background that Newsday got it wrong, and the RAD6000 answer provided by others is correct. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |

It's nice for rebootable web-based systems but i can't stand the tought of bloated, buggy code running inside the poor rover. Bad code is a very strong function of the programmers and only a weak function of language. C/C++/Ada/Java can all end up as bloated buggy code. I have worked on code where Assembly would have been just as easy to read if written properly in the first place. IMHO it's the code review process as well as the coding environment that can make all the difference. ie managers that have the attitude of "just get it done on time on matter what" are generally managers to avoid.
