Lasers in Space

The Defense Department’s Armed with Science blog writes: “In an effort to… (enhance the agency’s communications capabilities), NASA has directed the Goddard Space Flight Center (GSFC) to lead the Lunar Laser Communication Demonstration (LLCD).”

“The LLCD is NASA’s first dedicated two-way laser communications system. It’s the first demonstration that anyone has ever done with laser communications from the moon back to the Earth. It’s a pinpointed way to transfer information to and from space using lasers. Think fiber optic cables without the cable.”

“And it works.”
