“Mona Lisa” humans to the moon on the first using laser transmission image among the stars

NASA has used laser beams to transmit painting Mona Lisa to lunar flight & other; The lunar reconnaissance orbiter & throughout; , this is the first time human using laser for image data transmission among the stars.

the U.S. space agency said in a statement that it is the agency use & other; The lunar reconnaissance orbiter & throughout; Part of the laser communication experiment was carried out. Spacecraft out of earth usually is the use of radio communication, & other; The lunar reconnaissance orbiter & throughout; Is currently the only fly around other planets and can use the spacecraft of the laser communication.

this famous painting was first digital code, broken down into 152 & times; 200 pixels; Then each pixel into laser pulse, from the NASA Goddard space flight center in Maryland, to nearly 240000 miles (380000 km) and other outside; The lunar reconnaissance orbiter & throughout; , the data transfer rate is about 300 bits/SEC.

& other; The lunar reconnaissance orbiter & throughout; Instrument after receives the laser pulse on the reconstruction of the image, and then through the traditional radio system images back to earth, to verify the laser transmission success.
