Beaming Mona Lisa to the Moon

Why is the Mona Lisa smiling? You would too if your image is beamed to the moon with laser!
NASA scientists digitized the famous painting and sent it almost 240,000 miles away to the Lunar Reconnaissance Orbiter using laser pulses from NASA's Goddard Space Flight Center in Maryland:

For last March's Mona Lisa maneuver, researchers encoded a black-and-white version of Leonardo da Vinci's enigmatic masterpiece as a series of values in a 152-by-200-pixel grid. Each value represented a shade of black to gray to white, ranging from zero to 4,095. The signal for each pixel was then piggybacked on the ranging station's laser-tracking pulses: Each pulse was fired during one of 4,096 super-short designated time slots, at a rate of about 300 bits per second.
As the pulses were received in lunar orbit, LOLA's software used the precise timing of each pulse to figure out the grayscale value for a given pixel — and reassembled the black-and-white image. The process wasn't perfect: Atmospheric turbulence introduced laser transmission errors, even when the sky was clear. To accommodate the 15 percent error rate, the researchers used Reed-Solomon data coding, which is the same method used to smooth out the bumps in the playback of CDs and DVDs.

300 bits per second? That's a 300 baud modem! Definitely not broadband.
