That is so smart. I know we're talking about NASA, but I am still in awe. I read a bit of the paper, it's actually even more redundant than what you said: - snapdragon is only used for higher level functions of the flight: The SnapdragonTM processor has a 2.26 GHz Quad-core SnapdragonTM 801 processor with 2 GB Random Access Memory (RAM), 32 GB Flash memory, a Universal Asynchronous Receiver Transmitter (UART), a Serial Peripheral Interface (SPI), General Purpose Input/Ouput (GPIO), a 4000 pixel color camera, and a Video Graphics Array (VGA) black-and-white camera. This processor implements visual navigation via a velocity estimate derived from features tracked in the VGA camera, filter propagation for use in flight control, data management, command processing, telemetry generation, and radio communication. The SnapdragonTM processor is connected to two - for flight control they use 2 (redundant) automotive chips from Texas Instruments: TMS570LC43x high-reliability automotive processor operating at 300 MHz, with 512 K RAM, 4 MB flash memory, UART, SPI, GPIO. - these are all controlled by a radiation hardened board, the 3rd level of redundancy
