The engineering behind this image is crazy. When New Horizons reached Pluto, it was transmitting data at just 2,000 bits per second from nearly 3 billion miles away, slower than a 1990s dial up modem. Downloading all the flyby data took 16 months. After a 9 year journey, the spacecraft had to pass through a target window only 100 kilometers wide, arriving within 150 seconds of its planned time. Miss that window, and every preprogrammed observation would have pointed into empty space. Just 10 day
