NASA’s Psyche Mission utilizes Photons to increase Space Communications Performance and Efficiency

October 19, 2017 |

NASA Headquarters

Washington, D.C. – A spacecraft destined to explore a unique asteroid will also test new communication hardware that uses lasers instead of radio waves.

The Deep Space Optical Communications (DSOC) package aboard NASA’s Psyche mission utilizes photons — the fundamental particle of visible light — to transmit more data in a given amount of time. The DSOC goal is to increase spacecraft communications performance and efficiency by 10 to 100 times over conventional means, all without increasing the mission burden in mass, volume, power and/or spectrum.

NASA reports International Space Station uses OPALS instrument to further laser communications research

Pasadena, CA – Ever wonder why stars seem to twinkle? This effect is caused by variations in the density of our atmosphere that cause blurring in light coming from space. It’s pretty for stargazing, but a challenge for space-to-ground communications.

A key technology called adaptive optics corrects such distortions. By combining adaptive optics with a laser communications technology aboard the International Space Station, NASA is working toward advances in space communications that could have major benefits for our data transmission needs here on Earth as well.

NASA reports OPALS on International Space Station shows how Lasers can Speed Communications

Pasadena, CA – You may know opals as fiery gemstones, but something special called OPALS is floating above us in space. On the International Space Station, the Optical Payload for Lasercomm Science (OPALS) is demonstrating how laser communications can speed up the flow of information between Earth and space, compared to radio signals.

“OPALS has shown that space-to-ground laser communications transmissions are practical and repeatable,” said Matthew Abrahamson, OPALS mission manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. “As a bonus, OPALS has collected an enormous amount of data to advance the science of sending lasers through the atmosphere. We look forward to continuing our testing of this technology, which sends information to and from space faster than with radio signals.”

NASA to Beam Data down from International Space Station using new OPALS technology

July 14, 2013 |

Pasadena, CA – NASA will use the International Space Station to test a new communications technology that could dramatically improve spacecraft communications, enhance commercial missions and strengthen transmission of scientific data.

The Optical Payload for Lasercomm Science (OPALS), an optical technology demonstration experiment, could improve NASA’s data rates for communications with future spacecraft by a factor of 10 to 100.
