    | Are they sure it's not just Sun's JVM taking a break to do a GC?

    Unless, of course, the software was written
    in something like C++ (as has been suggested[?],
    and is more likely).

    In that case, would it be more likely caused by,
    "dangling pointers to objects in deleted heaps"
    perhaps? ;-)

      NASA is renowned for its antenna failures - the Hubble space
      telescope, Ulysses at Jupiter, and now their little radio-controlled
      go-cart on Mars.

      Uncle Al eagerly anticipates a Hummer-2 advert beginning with the $240
      million pigmy brain fart that couldn't call home. Anticipating that
      its working life would be less than 90 days because of dust
      accumulating on its solar panels is also precious. Hey NASA, "blow
      job."

      One presumes the same engineering glitch is in the other rover.

          There are go-to-lunch slow garbage collectors for C++ too, such as
          the "managed C++" abomination Microslop is trying to shove through
          the ECMA. Apparently nothing is safe from the "embrace and extend"
          standards pollution and proprietarizati on strategy.

          That can happen when some chimp-coder can't quite comprehend RAII.
          Another common fudgeup is to throw an exception from a destructor.

                          Or perhaps more to the point, not using Java was a good decision!
                          hint: in case you missed it, the rover doesn't use any Java code, the
                          Java is all for manipulating the data received back from the Rover.
