Fuk'n flash memory. Mars Rover Opportunity is having flash memory degradation. They had to reformat last month, and now they are having startup issues. Typical flash memory design life is 10-years. And this is even aerospace grade. imagine the cheap stuff in your home electronics.

  Bummer - but ten years on a planned 90-day mission is pretty good!

  @DoctorTom. You are very welcome. You will say the same thing if you experience a bad flash memory chip.
  
  @Stephen: MER was expected to operate for 90 days. But when they built it they used design parameters suitable for a 2-year lifespan. And validation tests of the design showed a 4-year lifespan.
  
  Many spacecraft operate way beyond their design life. And sometimes you have to plan a short mission to get initial funding going. With the hidden intent of going much longer....
