    NASA has developed a way to use lasers for communication by sending signals back and forth from Earth to the moon using the Lunar Laser Communication Demonstration, or LLCD.

    NASA has been using lasers on some of their new projects, including tracking satellites and sending a copy of Leonardo Da Vinci's Mona Lisa to the moon.

    But now, NASA has developed a way to use lasers for communication by sending signals back and forth from Earth to the moon using the Lunar Laser Communication Demonstration, or LLCD.

    The new technology has gone off without a hitch, successfully sending signals that contain transmitted data traveling 239 thousand miles at 622 megabits per second.

    This is the first laser based two way communication device, which will reportedly replace radio frequency contact, that has been used for so long between NASA and their spacecrafts.

    NASA's website says: "Compared to the days of dial-up, today's web-pages load at lightning speed over high-speed cable and fiber optic lines. NASA is moving away from their version of dial-up, radio frequency based communication, to their own version of high-speed Internet: optical communication."

    The recently launched LADEE spacecraft is carrying the LLCD, which is planned to last for 30 days, before an even longer demonstration that will take place, known as the Laser Communications Relay Demonstration, scheduled for a 2017 launch date.
