"This is the first time anyone has achieved one-way laser communication at planetary distances," David Smith, a researcher working with the LRO's Lunar Orbiter Laser Altimeter -- which received the Mona Lisa message -- said in a statement. "In the near future, this type of simple laser communication might serve as a backup for the radio communication that satellites use. In the more distance future, it may allow communication at higher data rates than present radio links can provide."
