The laser communication system for the Artemis II mission, known as the Orion Artemis II Optical Communications System (O2O), has arrived at NASA’s Kennedy Space Center. O2O, a system that significantly enhances data transmission, will transmit high-definition videos and other vital information from the moon to Earth, supporting further space exploration and facilitating groundbreaking discoveries.

The laser communications system, crucial for NASA’s Artemis II mission, has reached NASA’s Kennedy Space Center in Florida, where it will be integrated with the Orion spacecraft. The Orion spacecraft will transport astronauts around the moon, a feat not accomplished since the Apollo missions.

On November 16, 2022, NASA launched the Artemis I mission, an uncrewed flight test that pushed the human-rated Orion spacecraft farther into space than any previous mission. The subsequent mission, Artemis II, will thoroughly test all of Orion’s systems required for crewed spaceflight, setting the stage for future missions to the lunar surface. Additionally, the Artemis II mission will evaluate new and improved technologies, including the capabilities of laser communication.

Orion’s laser communications terminal, known as the Orion Artemis II Optical Communications System or O2O, is a vital component of the mission.

Laser communication systems, like O2O, offer missions increased data rates, enabling the transmission and reception of more information in a single transmission compared to traditional radio wave systems commonly used in NASA missions today. Greater data capacity leads to more significant discoveries.

“At a rate of 260 megabits per second, O2O is capable of transmitting 4K high-definition video from the Moon,” explained Steve Horowitz, O2O project manager. “In addition to video and pictures, O2O will facilitate the transmission and reception of procedures, pictures, flight plans, and establish a crucial link between Orion and mission control on Earth.”

Once data is collected, O2O will employ laser signals to transmit the information to one of two ground stations: Las Cruces, New Mexico, or Table Mountain, California. These locations were selected due to their minimal cloud coverage, which affects the quality of images and videos sent from Orion through O2O.

The O2O laser terminal is part of the Space Communications and Navigation (SCaN) program’s effort to incorporate optical technology, showcasing laser communications in multiple missions. The development of O2O involved a collaborative effort between engineers from NASA’s Goddard Space Flight Center and the Massachusetts Institute of Technology Lincoln Laboratory (MIT-LL). This partnership has successfully contributed to various laser communication missions, including the Lunar Laser Communications Demonstration (LLCD) in 2013, the Laser Communications Relay Demonstration (LCRD) in 2021, and the TeraByte InfraRed Delivery (TBIRD) payload in 2022. By demonstrating this technology in diverse space environments, SCaN highlights the benefits that laser communications can bring to future missions.

Before its delivery to Kennedy, the O2O laser terminal underwent rigorous environmental testing to ensure its functionality in the harsh space environment.

Laser communication terminals like O2O will facilitate the transmission of a greater volume of data to Earth, supporting scientists in conducting advanced investigations. The data collected during the Artemis II mission will inform NASA’s future lunar missions and aid in establishing a long-term presence on the Moon and eventually on Mars.

O2O is funded by the Space Communications and Navigation (SCaN) program at NASA Headquarters in Washington. The O2O terminal is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Collaborative partners include NASA’s Johnson Space Center in Houston, Lockheed Martin in Maryland, and the Massachusetts Institute of Technology Lincoln Laboratory.
