The lunar laser communications demonstration
Splet27. dec. 2024 · The Laser Communications Relay Demonstration (LCRD) has a two-year primary mission to demonstrate the potential of a bi-directional optical communications system that can transmit data space-to-space, space-to-ground, and ground-to-space at rates up to 1.2 gigabits per second. LADEE's Lunar Laser Communication Demonstration (LLCD) was a payload on NASA's Lunar Atmosphere and Dust Environment Explorer lunar orbiter. The LLCD pulsed laser system conducted a successful test on October 18, 2013, transmitting data between the spacecraft and its ground station on Earth at a distance of 385,000 kilometres (239,000 mi). This test set a downlink record of …
