SpaceTT: NASA tests transmitting data with lasers by beaming Mona Lisa into space

Mona Lisa beamed into space, used as a NASA test of Laser Data Transmission

A successful test of laser communication has just been complete by researchers at NASA according to Space.com. The agency tested laser transmission of data into space by beaming the Mona Lisa from earth to the Lunar Reconnaissance Orbiter some 240,000 miles away.

The LRO, which has been orbiting the moon since 2009, was chosen over other space craft because it was already fitted with laser communication gear. The image of the Mona Lisa was subdivided into 150 x 200 pixel segments and then beamed to the LRO from the Goddard Flight Center at a rate of about 300 bits per second.

"This is the first time anyone has achieved one-way laser communication at planetary distances," said David Smith, a researcher working with the LRO's Lunar Orbiter Laser Altimeter. "In the near future, this type of simple laser communication might serve as a backup for the radio communication that satellites use."
