The most advanced vehicle ever sent to Mars had a technical problem a few days after it’s launch. A problem in it’s guiding system: a strange reboot experimented three days after starting the journey, so unexpected that it was decided to use an alternative system before trusting in one whose performance and reliability could not be fully ensured at the time.
After several months of tests and simulations of all types, technicians have found, isolated and fixed the problem. The problem was related to the memory management unit of Curiosity Core processor, whose design, in very specific circumstances, could cause bugs that prevented the instructions from executing correctly. That's what happened the 29th of November, resulting in the reboot of the guiding system. The technicians sent this week a new software in order to fix the problem, through the reconfiguration of the robot
The operation was completed successfully and now Curiosity is flying towards it´s target using it’s tracking system normally. Actually, the 26th of January, the curiosity viewed Mars for the first time, even though it is still pretty far...
