Curiosity Continues Computer Preps, Gets 'Attitude Adjustment'
18 Jul 2012
July 18: Activities continue to prepare Curiosity's redundant main computers, or Rover Compute Elements, for arrival at Mars. Today, Curiosity's RCE-A computer, which was swapped with the backup computer yesterday, is being cold reset, or rebooted, while in online, or backup, mode. Work continues to upload updated flight sequences and communications parameters for Curiosity's entry, descent and landing and surface operations to the spacecraft. In addition, mission controllers yesterday completed the 21st attitude control turn on the Mars Science Laboratory spacecraft, a day early. This turn adjusts the spacecraft's orientation to keep its medium-gain antenna pointed toward Earth for communications. This was the second-to-last attitude control turn planned before landing day.
