Space Missions & Technology
Laser Communications
An optical link that carries information using a modulated light beam.
Why it matters
Optical links expand design options for moving large scientific data volumes.
Technology / mission infrastructure
Overview
Laser links can offer high data rates, but narrow beams demand accurate pointing. Clouds and atmospheric conditions affect ground links. Optical communications complement rather than automatically replace radio systems.
Educational reference, reviewed . This page is not a live mission-status report.
How it works
A transmitter encodes data onto laser light. A receiving telescope collects it, and detectors recover the signal. Acquisition and tracking maintain alignment between the terminals.
