NASA has revealed a new system of voice communication via a light beam that has both space and down-to-earth-potential.
It is called a Retrometer.
The space agency says it can assist astronauts in spacecraft docking operations and provide communication after they land on the bare face of a strange planet.
The Retrometer also may be used in industrial plants or factories, on construction sites, and in theaters and conventions for audience participation.
