Could you hack into Mars rover Curiosity? | ExtremeTech: "The first approach would involve the would-be hacker building the equivalent of NASA’s Deep Space Network (DSN), a worldwide network of big-dish antenna that send and receive spacecraft signals, and perform radio astronomy. To perform uplink communications (to the rover), the DSN’s biggest antennae — 230-feet (70-meter) dishes — are outfitted with transmitters that deliver up to 400 kilowatts of output power. The hacker would also have to replicate the exact same encoding scheme (probably QPSK, the same as satellite TV) and use the same frequency (X band, around 8GHz)."
