A Study of an Optical Lunar Surface Communications Network with High Bandwidth Direct to Earth LinkAnalyzed optical DTE (direct to earth) and lunar relay satellite link analyses, greater than 200 Mbps downlink to 1‐m Earth receiver and greater than 1 Mbps uplink achieved with mobile 5‐cm lunar transceiver, greater than 1Gbps downlink and greater than 10 Mpbs uplink achieved with 10‐cm stationary lunar transceiver, MITLL (MIT Lincoln Laboratory) 2013 LLCD (Lunar Laser Communications Demonstration) plans to demonstrate 622 Mbps downlink with 20 Mbps uplink between lunar orbiter and ground station; Identified top five technology challenges to deploying lunar optical network, Performed preliminary experiments on two of challenges: (i) lunar dust removal and (ii)DTN over optical carrier, Exploring opportunities to evaluate DTN (delay-tolerant networking) over optical link in a multi‐node network e.g. Desert RATS.
