Call it the ultimate in high art: Using a well-timed laser, NASA scientists have beamed a picture of Leonardo da Vinci's masterpiece, the Mona Lisa, to a powerful spacecraft orbiting the moon, marking a first in laser communication.
 
The laser signal, fired from an installation in Maryland, beamed the Mona Lisa to the moon to be received 240,000 miles (384,400 km) away by NASA's Lunar Reconnaissance Orbiter, which has been orbiting the moon since 2009. The Mona Lisa transmission, NASA scientists said, is a major advance in laser communication for interplanetary spacecraft.

ただ送ったわけではなく、通信エラーを修正して正しい情報として受け取れるかどうかを確認したとのこと。
でも通信レートが300 bpsでは、初期のパソコン通信並みの速度でしかない。今後、どこまで改善されていくのだろうか。
