Arthur T Knackerbracket has processed the following story:

Our televisions and computer screens display news, movies, and shows in high-definition, allowing viewers a clear and vibrant experience. Fiber optic connections send laser light densely packed with data through cables to bring these experiences to users.

NASA and commercial aerospace companies are applying similar technologies to space communications, bringing optical speeds to the final frontier. Free-space optical communications leverages recent advancements in telecommunications to allow spacecraft to send high-resolution images and videos over laser links.

"Free-space" refers to the absence of the insulated, fiber optic cables that enable the terrestrial internet. Free-space laser communications flow freely through the vacuum of space, however atmosphere poses unique challenges to communications engineers.

NASA's Laser Communications Relay Demonstration (LCRD) will send data to and from ground stations and, eventually, in-space user missions over laser links.

"LCRD leverages the work done in the telecommunications industry for the past several decades. We're taking the concepts that they've created and applying them to space," said Russ Roder, product design lead for LCRD's optical module. "The trick is that we have to optimize the technology for space."

LCRD's mission will be spent proving out the technology by testing laser communications capabilities with experiments from NASA, other government agencies, academia, and—in particular—the commercial aerospace community. Industry-developed experiments will allow companies to test their own technologies, software, and capabilities. NASA is providing these opportunities to grow the body of knowledge surrounding laser communications and promote its operational use.

    I don't get it.
