Mars Opportunity Rover about to undergo long-distance flash memory reformat

story imageYou think it's stressful to remotely reboot a server in a datacenter in another state? Talk to NASA, where An increasing frequency of computer resets on NASA's Mars Exploration Rover Opportunity has prompted the rover team to make plans to reformat the rover's flash memory.
The resets, including a dozen this month, interfere with the rover's planned science activities, even though recovery from each incident is completed within a day or two. Flash memory retains data even when power is off. It is the type used for storing photos and songs on smart phones or digital cameras, among many other uses. Individual cells within a flash memory sector can wear out from repeated use. Reformatting clears the memory while identifying bad cells and flagging them to be avoided.

"Worn-out cells in the flash memory are the leading suspect in causing these resets," said John Callas of NASA's Jet Propulsion Laboratory, Pasadena, California, project manager for NASA's Mars Exploration Rover Project. "The flash reformatting is a low-risk process, as critical sequences and flight software are stored elsewhere in other non-volatile memory on the rover."

Somebody over at Soylent called the Internet's news reporting a huge echo chamber. "What news sites do you visit?" someone asked, to which the reply was, "Doesn't matter; they're all reporting the same stuff anyway and hardly anyone is producing original content."

I think Slashdot and the Register are both already reporting this, and now I see Soylent has published it as well. Holy crap, what a lot of work for nothing.

The alternative is of course to follow and scour endless, personal blogs. Who's got the time and energy for that?

Really? Wouldn't know. I read here first, others second or third via RSS. IF it's a dup I skip it.

Next story please :)

Wow. Much obliged, then! If I have made one A/C happy, then perhaps it was worth it. :)

I don't read /. anymore, Pipedot's where the echoes begin for me. Thank you!
