How did we ever make enough sense of these 1's and 0's to get these magnificent images?


Spacecraft engineers and computer scientists have had to solve many big problems. But none of these problems could be tackled without one thing: a special language so people could communicate with machines. That language makes . . .

  • The huge dish antennas that pick out the spacecraft's signal from millions of miles away seem very smart.
