NASA Laser Communication System Sets Record with Data Transmissions to and from Moon

NASA's Lunar Laser Communication Demonstration (LLCD) has made history using a pulsed laser beam to transmit data over the 239,000 miles between the moon and Earth at a record-breaking download rate of 622 megabits per second (Mbps).

LLCD is NASA's first system for two-way communication using a laser instead of radio waves. It also has demonstrated an error-free data upload rate of 20 Mbps transmitted from the primary ground station in New Mexico to the spacecraft currently orbiting the moon

NASA | LLCD: Proving Laser Communication Possible

On October 18th, 2013 the Lunar Laser Communication Demonstration (LLCD) made history, transmitting data from lunar orbit to Earth at a rate of 622 Mbps. LLCD, flying aboard NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE), is the first NASA mission dedicated to proving high-rate, two-way laser communications is possible. LLCD not only demonstrated a record-breaking download rate but also an error-free data upload rate of 20 Mbps. The laser beam was transmitted the 239,000 miles from the primary ground station at NASA's White Sands Complex in Las Cruces N.M., to the LADEE spacecraft in lunar orbit.

Moon mission beams laser data to ESA station

1 November 2013 ESA’s ground station on the island of Tenerife has received laser signals over a distance of 400 000 km from NASA’s latest Moon orbiter. The data were delivered many times faster than possible with traditional radio waves, marking a significant breakthrough in space communications.

The Lunar Atmosphere and Dust Environment Explorer, or LADEE, was launched on 7 September and arrived in orbit around the Moon in October. In addition to probing the Moon’s environment, it’s also carrying a new laser terminal.
