The LSAF serves as the backbone for the LCRD components. Attached to the LSAF are the two optical modules, which generate the infrared lasers that transmit data to and from Earth. A star tracker is also attached here. These components are visible on the left side of this image. Other LCRD components, such as the modems that encode data into laser signals, are attached to the back of the LSAF. u003cstrongu003eCredits: NASA\u2019s Goddard Space Flight Centeru003c\/strongu003e<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>The Laser Communications Relay Demonstration (LCRD) aims to showcase the unique capabilities of <a href=\"https:\/\/www.nasa.gov\/lasercomms\">optical communications<\/a>. Currently, most NASA missions use radio frequency communications to send data to and from spacecraft. Radio waves have been used in space communications since the beginning of space exploration and have a proven track record of success. However, as space missions generate and collect more data, the need for enhanced communications capabilities becomes paramount.<\/p>\n\n\n\n<p>Optical communications is one of these enhancements and will provide significant benefits for missions, including bandwidth increases of 10 to 100 times more than radio frequency systems. Additionally, optical communications provides decreased size, weight, and power requirements. A smaller size means more room for science instruments. Less weight means a less expensive launch. Less power means less drain on the spacecraft\u2019s batteries. With optical communications supplementing radio, missions will have unparalleled communications capabilities.<\/p>\n\n\n\n<p>The LCRD payload is hosted aboard the U.S. Department of Defense\u2019s Space Test Program Satellite 6 (STPSat-6). After launch Dec. 7, 2021, engineers at LCRD\u2019s mission operations center in Las Cruces, New Mexico, turned the payload on and prepared it to start transmitting data over infrared lasers. Until its first user is launched, LCRD will practice sending test data to and from its ground stations. This test data will be sent up through radio frequency signals from the mission operations center and then the LCRD spacecraft will reply over optical signals. This test data will include spacecraft health data; tracking, telemetry, and command data; and sample user data to ensure LCRD is properly operating.<\/p>\n\n\n\n<p>Future missions in space will send data to LCRD, which will then relay the data down to designated ground stations on Earth. NASA has been leveraging communications relay satellites since 1983 when the first <a href=\"https:\/\/www.nasa.gov\/mission_pages\/tdrs\/home\/index.html\">Tracking and Data Relay Satellite<\/a> launched. With relays, missions are not required to have direct line-of-sight to antennas on Earth, increasing communications coverage. LCRD creates a continuous path for data flowing from missions in space to ground stations on Earth, making a complete end-to-end system. Additionally, LCRD\u2019s ability to both send and receive data from missions and the ground stations makes the system two-way. Together, these capabilities make LCRD NASA\u2019s first two-way, end-to-end optical relay.<\/p>\n\n\n\n<p>Unlike radio frequency communications, optical signals cannot penetrate cloud coverage, so NASA must build a system flexible enough to avoid interruptions due to weather. LCRD will transmit data received from missions to two ground stations, located in Table Mountain, California, and Haleakal\u0101, Hawaii. These locations were chosen for their minimal cloud coverage. LCRD will test different cloud coverage scenarios, gathering valuable information about the flexibility of optical communications.<\/p>\n\n\n\n<p>LCRD is a technology demonstration that will pave the way for future optical communications missions. Future missions that decide to use optical communications could potentially use LCRD as their relay. One of LCRD\u2019s first operational users will be the Integrated LCRD Low-Earth Orbit User Modem and Amplifier Terminal (<a href=\"https:\/\/www.nasa.gov\/directorates\/heo\/scan\/opticalcommunications\/illuma-t\/\">ILLUMA-T<\/a>), a payload that will be hosted on the International Space Station. The terminal will receive high-resolution science data from experiments and instruments onboard the space station and then transfer this data to LCRD, which will then transmit it to a ground station. After the data arrives on Earth, it will be delivered to mission operation centers and mission scientists.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"LCRD Ready for Launch\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/Es5qqfMTwT8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Milestones<\/h2>\n\n\n\n<ul>\n<li><a href=\"https:\/\/www.nasa.gov\/press-release\/nasa-s-laser-communications-tech-science-experiment-safely-in-space-0\/\">On Dec. 7, 2021<\/a>, LCRD launched from the Cape Canaveral Space Force Station in Florida.
