NASA tests laser communications by sending Mona Lisa to space

A new experiment by NASA proving the effectiveness of laser communications has raised the prospect that beam technology could one day replace radio. That’s after NASA scientists successfully beamed an image of the Mona Lisa to the moon.
­NASA scientists usually use lasers to track the position of its Lunar Reconnaissance Orbiter (LRO) – the robotic spacecraft that creates gravitational maps of the moon. It collects the information then transmits it back to earth at a rate of 50 Mbs.
Then NASA scientists had the bright idea of reversing the flow by beaming an image of the Mona Lisa to the LRO using lasers.
