This summer, NASA will launch its Laser Communications Relay Demonstration (LCRD), setting the stage for high-speed transmission of data between planets.
NASA missions have been using the same technology — radio frequency communications — since the 1950s and the beginning of spaceflight.
With the advent of technologies such as 4K video, limits to radio technology have become increasingly evident. To transmit a complete map of Mars, it would take roughly nine weeks with current radio technologies. With lasers, it would take about nine days.
