This paper provides an update on NASA's Laser Communications Relay Demonstration Project (LCRD), a joint project between NASA's Goddard Space Flight Center (GSFC), the Jet Propulsion Laboratory, California Institute of Technology (JPL), and the Massachusetts Institute of Technology Lincoln Laboratory (MIT/LL). LCRD will provide a minimum of two years of high data rate optical communications services to demonstrate a concept of operations for future mission critical Earth relay satellites. LCRD is expected to launch in June 2019 and demonstrate how optical communications can meet NASA's growing need for higher data rates, or for the same data rate provided by a comparable RF system, how it enables lower power, lower mass communications systems on user spacecraft. In addition, LCRD's architecture will allow it to serve as a testbed in space for the development of additional symbol coding, link and network layer protocols, etc. LCRD's mission and architecture has slowly evolved since the project first started and this paper will provide an update of LCRD and planned capabilities and experiments.
