The moon now has a better internet connection than you do

After months of testing, it looks like the Lunar Laser Communication Demonstration is ready to be deployed in a real world scenario. Among other things, it likely means that we can send HD video into space at a greater speed than you can stream it to your home. Transmitting information from space back down to Earth has always been a struggle. The radio frequency systems used today are not capable of delivering any significant quantity of real time information through space, but it was the only thing we had. Much in the same way that some environments have successfully attempted to use lasers for packet transmission here on Earth, a huge laser system in White Sands, New Mexico has demonstrated that we can send information to the Moon and back in record time. A joint research group consisting of NASA and the MIT Lincoln Lab have been successfully shooting lasers full of internet back and forth from a spacecraft orbiting the Moon since October. The results of this laser based communication system showed a possible 622MB per second (that’s megabit, not megabyte) transmission rate.

  These speeds are affected by a number of variables, including the position of the spaceship relative to the Sun and the condition of the atmosphere at the time of transmission. Unlike some forms of laser communication, this transmission post has proven it can even transmit data through thin clouds. In one test an HD video was sent to the Moon and back in 7 seconds, an impressively short trip compared to how long it takes to fire up Netflix here on Earth. This is huge progress for interstellar communications, and in a world where many science eagerly wait for the next high resolution photo from Curiosity to be transmitted and reassembled here on Earth it’s a clear sign that we need this moving forward. With the proven success of this transmission system, it will be interesting to see how long it will be before real world applications for this technology are implemented in our existing operations.

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.

NASA Laser Communication System Sets Record 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 | Downloads the Future.

LLCD will be NASA’s first-step in creating a high performance space-based laser communications system. The LLCD mission consists of space-based and ground-based components. The Lunar Laser Space Terminal (LLST) is an optical communications test payload to fly aboard the LADEE Spacecraft and it will demonstrate laser communications from lunar orbit.The ground segment consists of three ground terminals that will perform high-rate communication with the LLST aboard LADEE. The primary ground terminal, the Lunar Laser Ground Terminal (LLGT) is located in White Sands, NM and was developed by MIT/Lincoln Laboratory and NASA. The ground segment also includes two secondary terminals located at NASA/JPL’s Table Mountain Facility in California and the European Space Agency’s El Teide Observatory in Tenerife, Spain. The main goal of LLCD is proving fundamental concepts of laser communications and transferring data at a rate of 622 megabits per second (Mbps), which is about five times the current state-of-the-art from lunar distances. Engineers expect future space missions to benefit greatly from the use of laser communications technology.
