NASA successfully beamed a high-definition video 260 miles from the International Space Station to Earth Thursday using a new laser communications instrument.

Transmission of "Hello, World!" as a video message was the first 175-megabit communication for the Optical Payload for Lasercomm Science (OPALS), a technology demonstration that allows NASA to test methods for communication with future spacecraft using higher bandwidth than radio waves.

"The International Space Station is a test bed for a host of technologies that are helping us increase our knowledge of how we operate in space and enable us to explore even farther into the solar system," said Sam Scimemi, International Space Station division director at NASA Headquarters in Washington. "Using the space station to investigate ways we can improve communication rates with spacecraft beyond low-Earth orbit is another example of how the orbital complex serves as a stepping stone to human deep space exploration."

Optical communication tools like OPALS use focused laser energy to reach data rates between 10 and 1,000 times higher than current space communications, which rely on radio portions of the electromagnetic spectrum.
