Here's an interesting article on Deep Space 1: eet.com Note the remarks about the Mars Pathfinder and VXworks and code written in C: “We had a very aggressive schedule to put a new processor in DS 1,” recalled Jet Propulsion Lab avionics project manager Dankai Liu. But JPL “soon realized that the program was just too aggressive and that we didn't really need it. So we used the same computer” used on Pathfinder. That system was a radiation-hardened version of an IBM Power architecture RS 6000, running at 20 MHz and armed with only 4 Mbytes of DRAM. The system would host a VXworks real-time kernel. Code would be written in C and stored in two mostly redundant banks of E2PROM. Since Wind River's VXworks is being ported to the PTSC chip, it's too bad it wasn't available for this mission. Perhaps future missions??
