Curiosity… how many computer onboard???
It began as one of the most spectacular missions for the technologies used to land a Rover as big as a Smart on Mars, but it is proving to be even more spectacular for the hardware design of Curiosity.
It is a news of these days, in fact, that Curiosity has had problems in flash memory of the main computer; Can NASA have overlooked the possibility that a similar problem can invalidate a mission that has cost of several million of dollars? Of course not. In fact, the control of the rover has been swapped to a second computer that will be made fully operational shortly after a short passage in “safe mode”. In the meantime, the land-based operators can easily restore the full functionality of the computer that has been just sent to rest.
Power of the redundancy.
