On July 16, 2020, the Laser Communications Relay Demonstration (LCRD) payload was installed and integrated on the U.S. Department of Defense Space Test Program Satellite 6 (STPSat-6) in preparation for a 2021 launch.

As an experimental payload, LCRD will demonstrate the robust capabilities of laser communications, which can provide significant benefits to missions, including bandwidth increases of 10 to 100 times more than radio frequency systems.

Prior to spacecraft integration, the LCRD payload went through several tests and blanket installations at Northrop Grumman's integration and test facility in Sterling, Virginia. While LCRD underwent testing, Northrop Grumman technicians also prepared the spacecraft for LCRD's integration.

Now that the two components have been fully integrated, they will undergo environmental testing and end-to-end compatibility testing to ensure the spacecraft and payload can properly communicate with one another.

LCRD will be NASA's first two-way optical relay, sending and receiving data from missions in space to mission control on Earth. LCRD is paving the way for future optical communications missions, which could use LCRD to relay their data to the ground.

In 2022, the Integrated LCRD Low-Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T), hosted on the International Space Station, will be the first LCRD demonstration from low-Earth orbit.

LCRD was built by Goddard Space Flight Center in Greenbelt, Maryland, before being shipped to the Northrop Grumman facility in January 2020. LCRD is funded by NASA's Space Technology Mission Directorate and the Human Exploration and Operations Mission Directorate, and managed by NASA's Technology Demonstration Missions and the Space Communications and Navigation (SCaN) program office.

Portable system boosts laser precision, at room temperature
Boston MA (SPX) Jul 13, 2020
Physicists at MIT have designed a quantum "light squeezer" that reduces quantum noise in an incoming laser beam by 15 percent. It is the first system of its kind to work at room temperature, making it amenable to a compact, portable setup that may be added to high-precision experiments to improve laser measurements where quantum noise is a limiting factor. The heart of the new squeezer is a marble-sized optical cavity, housed in a vacuum chamber and containing two mirrors, one of which is smaller ... read more
