Ya'll might want to keep track of this:

Hopefully, it's just a software glitch and they can recover it.

Let's hope...durn it...

Maybe it's just decided to start screening its calls...

I agree. The folks at JPL are geniuses, and I hope they figure this
one out and fix it.

But not all failure modes are bad.

Top 10 Good Reasons For Spirit's Problems

10. Probe sacrificed itself to end Jerry/TRA/NAR war.
9. NASA is embarrassed: Adirondack is meteorite from Earth.
8. You simply don't leave an expensive vehicle like that unlocked in
that kind of neighborhood.
7. Spirit fell asleep listening to State of the Union address. Wait a
couple days and it will wake up.
6. NASA is covering up most recent transmission from Spirit: "I'm
sorry Dave, but I can't do that."
5. Martians mistook Spirit for entry in "Robot Wars" TV show.
4. Spirit is installing new Microsoft Windows XP upgrade; once
installation is finished and the system rebooted, everything will be
fine.
3. Note for next probe: Do not make rover out of things edible by
silicon and metal-based life.
2. Liquid water does bad things to electronic equipment.
1.  Drilling woke up Adirondack and the creature ("What do you mean
you think I'm a rock?") retaliated.

Anyone remember a story about Martian children climbing all over a
NASA probe? I think it was by Niven and  one of the kid's names was
"Ditdu" or "Ditdoo."

 > Windows Blue Screen Of Death.

 From http://www.gcn.com/vol1_no1/daily-updates/24540-1.html
Wind River Systems Inc. made the operating system, VxWorks OS, that runs on
the radiation-hardened 20-MHz Rad 6000 CPU module aboard the NASA rovers. Mike
Deliman, a technical staff member at the Alameda, Calif., company, has served
the Mars rover project as chief engineer for the OS.

Spirits onboard computer has only 128M of memory, so theres not a whole lot
of instructions we can give it, Deliman said.

Hard to fit much in 128M isn't it...

Nobody needs more than 16k of ram (or whatever the quote says).

    Not at all- 128 M is a HUGE HUGE amount of RAM for a spacecraft. In
fact, I am sure a lot of that (the vast majority, in fact) is data
storage instead of instructions and working variables.  We managed one
of the more complex space comptuer jobs with 2 computers with 384 and
512 *K* of memory, and the first computer-controlled spacecraft I worked
had 1024 WORDS of volatile memory, and 8192 WORDS of ROM. Managed to put
a lot of functions in there - even a crude orbit ephemeris propagation.

    One you get out of the GUI/Interactive world, and into the embedded
processor/ assembly code world, the *** "bloat" of features is not
needed.

     Actually, I am working this instant (well, as soon as stop typing
into USENET) on a system that uses the same processor and VXWorks. We
don't have anything like 128M - and I have no idea what we could even
think up to put in that much memory.

I agree, 128M is huge for embedded app.  I should have put a smiley at the end
of my statement. ;-)

I'm going to go back and look at the images of Spirit very closely.
Considering the problems that have come up, I bet I will be able to find
a "Powered by Microsoft" and an "Intel Cintrino Inside" sticker on it
somewhere.  ;)

WinXP can't even pass gas with less ram than that, but a good OS can do
a whole lot of stuff with a lot less than 128mb or ram.

I'll add a couple more.

I believe it was 640K, if you're referring to Bill Gates.
