The Lunar Laser Communication Demonstration: a Successful First Step for Deep-Space Lasercom Systems


Radio waves have been the standard method for deep-space communications since the Apollo Mission. However, the recent success of the Lunar Laser Communications Demonstration (LLCD) program will clearly revolutionize the way data is sent and received from deep space. LLCD demonstrated record-breaking optical up/downlinks between Earth and the Lunar Lasercom Space Terminal (LLST) payload on NASA’s Lunar Atmosphere Environment Explorer (LADEE) satellite orbiting the Moon.  The system included the development of a novel space terminal, a novel ground terminal, two major upgrades of existing ground terminals, and a capable and flexible ground operations infrastructure. This talk will give an overview of the system architecture and the several terminals, basic operations of both the link and the whole system, and some typical results focusing on operations.

Farzana Khatri, MIT Lincoln Laboratory


Farzana Khatri has been a Technical Staff Member in the Optical Communication Technology group at MIT Lincoln Laboratory in Lexington, MA since 2002.  Most recently, she was a key player in the Lunar Laser Communication Demonstration (LLCD) project, a first-of-its-kind, record-breaking Moon to Earth free space laser communication system demo. Her roles in the LLCD project have included system engineering, test bed design, system /subsystem /spacecraft I&T, and operations. Before coming to Lincoln, Farzana worked at AT&T/Tyco Submarine Systems on long-haul undersea fiber optic systems as well as at Sycamore Networks on long-haul terrestrial fiber optic systems.  She received the S.B., S.M., and Ph.D. degrees from MIT in 1990, 1992, and 1996 where her doctoral thesis was on optical soliton communications systems under Professor Hermann A. Haus.
