Curiosity Computer Preps for Arrival
16 Jul 2012
July 16: Beginning today, Curiosity's redundant main computers, or Rover Compute Elements, will be power-cycled while in the online, or backup mode. The process, called a cold reset, reboots the computer, resetting it to a predictable, default state prior to the mission's arrival at Mars. This activity begins today with the reboot of the backup computer while in the online state and will continue through July 20. Tomorrow, the prime and backup computers will be swapped, and the reboot process will be repeated on Thursday with the other computer.
