Launch Date Set for NASA’s Laser Communications Relay Demonstration

NASA’s Laser Communications Relay Demonstration (LCRD) will launch aboard the U.S. Department of Defense’s (DoD) Space Test Program Satellite-6 (STPSat-6) spacecraft, targeted for Monday, Nov. 22, 2021 on a United Launch Alliance Atlas V 551 rocket from Launch Complex 41 on Cape Canaveral Air Force Station in Florida.

The LCRD technology demonstration is a step towards making operational laser, or optical, communications a reality. As space missions generate and collect more data, higher bandwidth communications technologies are needed to send it all back home. Laser communications will significantly benefit missions by increasing bandwidth 10 to 100 times more than radio frequency systems.

LCRD will implement various laser experiments to test the technology’s functionality and capabilities. Technology demonstrations like LCRD will enable the use of laser communications systems for future missions as NASA works to establish a robust presence on the Moon and prepares for crewed missions to Mars.

STPSat-6 is part of the third Space Test Program, or STP-3. To learn more about STP-3, visit:
