Perhaps it's not entirely clear from the Wind River press release, but while the Pathfinder *lander* ran vxWorks (on an RS6000, a port done for this mission) the Sojourner ran a much smaller system - I don't believe there's ever been an 8-bit vxWorks port in any case, but several references describe it as "simple single-threaded" or "serial", and specifically says "Sojourner has no on-board operating system".

Two CPUs on Curiosity?[edit]

This article states there are 2 CPUs on Curiosity, where one of them is a backup. If you have a link to official source to validate this information, then please correct article and add reference. Thanks. • SbmeirowTalk • 18:31, 16 August 2012 (UTC)

First of all thanks for that notice. It is good question. I will try to find some offical source.--TuxFighter (talk) 10:13, 18 August 2012 (UTC)
