Curiosity Swaps Computers, Gets Updated Arrival Data
17 Jul 2012
July 17: Activities continue through July 20 to prepare Curiosity's redundant main computers, or Rover Compute Elements, for arrival at Mars. Today, the computer that has been operating as Curiosity's prime computer is being swapped with the backup computer. On Wednesday July 18, that computer will be cold reset, or rebooted, while in online, or backup mode, following the same process used to cold reset the redundant computer on July 16. In addition, beginning today and continuing through July 20, updated flight sequences and communications parameters for Curiosity's entry, descent and landing and surface operations will be uploaded to the spacecraft.
