NASA’s laser relay system has achieved its very first link.
NASA announced on Wednesday that its Laser Communications Relay Demonstration (LCRD) and its Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T) had achieved their first communication. Since its installation aboard the space station, scientists have used the system to conduct over 300 experiments to “refine” the technology, exchanging data at a rate of 1.2 gigabits-per-second, according to NASA.
NASA scientists believe that the use of these types of laser communication systems can provide “more efficient, lighter systems, increased security, and more flexible ground systems.”
“We have demonstrated that we can overcome the technical challenges for successful space communications using laser communications,” said David Israel, a NASA space communications and navigation architect. “We are now performing operational demonstrations and experiments that will allow us to optimize our infusion of proven technology into our missions to maximize our exploration and science.”
Scientists hope to use laser communication in future applications such as Deep Space Optical Communications, Lunar Laser Communications Demonstrations, Orion Artemis II Optical Communications Systems, and more.
“ILLUMA-T’s first link with LCRD – known as first light – is the latest demonstration proving that laser communications is the future.” said Dr. Jason Mitchell, director of SCaN’s Advanced Communications and Navigation Technology division. “Laser communications will not only return more data from science missions, but could serve as NASA’s critical, two-way link to keep astronauts connected to Earth as they explore the Moon, Mars, and beyond.”
NASA scientists have been preparing to make use of this new communication system since early this year. SpaceX’s 29th commercial resupply mission carried the final component of the new relay, NASA’s ILLUMA-T, to the International Space Station in November, as previously reported by The Dallas Express.
