The Laser Communications Relay Demonstration (LCRD) is a NASA mission that will test laser communication in space for extremely long distances,[1] between Earth and geosynchronous orbit.
After being integrated into
Results from LCRD's first year of experiments in orbit have been shared online[5] and through a SPIE publication.[6]
Overview
The LCRD mission was selected for development in 2011, with a launch on board a commercial satellite scheduled for 2019.[7] The technology demonstration payload will be positioned above the equator, a prime location for line-of-sight to other orbiting satellites and ground stations. Space laser communications technology has the potential to provide 10 to 100 times higher data rates than traditional radio frequency systems for the same mass and power. Alternatively, numerous NASA studies have shown that a laser communications system will use less mass and power than a radio frequency system for the same data rate.[8]
The LCRD mission is managed by NASA's Goddard Space Flight Center (GSFC) and in partnership with NASA's Jet Propulsion Laboratory in Southern California and the Massachusetts Institute of Technology Lincoln Laboratory.[8]
In May 2018, the General Accounting Office (GAO) says there have been delays, funding cuts, and cost overruns but it should be ready to launch by November 2019,
By April 2020, after further delays and cost overruns, it was expected to launch in January 2021, as a payload on a U.S. Air Force

Project purpose
The goal of the Laser Communications Relay Demonstration project is to prove the utility of bidirectional optical communications relay services between geosynchronous orbit and Earth. The project supports the advanced communications, navigation, and avionics exploration key focus areas. This effort will prove optical communications technology in an operational setting, providing data rates up to 100 times faster than today's radio frequency-based communication systems. The demonstration will measure and characterize the system performance over a variety of conditions, develop operational procedures, assess applicability for future missions, and provide an on-orbit capability for test and demonstration of standards for optical relay communications. This capability, if successfully demonstrated, could be quickly infused into NASA missions, other Federal agencies, and U.S. satellite manufacturers and operators given the rising demand for bandwidth.[15]
Laser Communications Relay Demonstration will fly as a hosted payload with the U.S. Air Force Space Test Program (STPSat-6). Upon a successful flight demonstration, NASA will provide the communications industry with access to the integrated system to test these new capabilities for commercial applications.[15]
ILLUMA-T
One of LCRD's first operational users will be the Integrated LCRD Low-Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T), a payload hosted on the International Space Station. The terminal will receive high-resolution science data from experiments and instruments onboard the space station and then transfer this data to LCRD, which will then transmit it to a ground station. After the data arrives on Earth, it will be delivered to mission operation centers and mission scientists. The ILLUMA-T payload was sent to the ISS on SpaceX CRS-29 on 10 November 2023.[16]
The terminal achieved first light, on 5 December, 2023.[17]
Project parameters
LCRD will conduct a minimum two-year flight demonstration to advance optical communications technology toward infusion into Near Earth operational systems while growing the capabilities of industry sources. Objectives include:[15]
- Demonstrating bidirectional optical communications between geosynchronous Earth orbit and Earth;
- Measuring and characterizing the system performance over a variety of conditions;
- Developing operational procedures and assessing applicability for future missions; and
- Providing an on-orbit capability for test and demonstration of standards for optical relay communications.
Ground stations
LCRD will use two ground stations, Optical Ground Station (OGS)-1 and -2, at Table Mountain, California, and Haleakalā, Hawaii.[18]
