Revolutionizing Space Exploration: The Future of Laser Communications

Potential Future Trends in Laser Communications for Space Missions

NASA’s Artemis program is paving the way for the future of space exploration, and one key aspect of this program is the development and implementation of advanced laser communications systems. Laser, or optical, communications offer several advantages over traditional radio waves, including higher data rates and faster transmission times. As science instruments continue to evolve and capture high-definition data, the need for expedited ways to transmit information becomes crucial.

The Advantages of Laser Communications

Missions that use laser technology can send and receive more information in a single transmission compared to those using radio waves. Laser communications systems provide data rates that are 10 to 100 times higher than current radio systems used in space missions. For example, transmitting a complete map of Mars back to Earth would take approximately nine weeks with radio frequency systems, but with lasers, it would only take about nine days. This significant improvement in data transmission capabilities will revolutionize space exploration and enable faster and more efficient communication between spacecraft and ground stations.

The Role of Small Businesses

NASA recognizes the importance of partnerships with private industry and small businesses in the development of laser communication technologies. Through collaborations, NASA’s Space Communications and Navigation (SCaN) Program funded the successful development of a new piece of laser technology called the Basestation Optical Laser Terminal. This four-channel laser unit has the potential to enable high-power communications to the Moon during the Artemis II flight test. By supporting small businesses like Fibertek Inc., NASA ensures the establishment of a healthy domestic supply chain for laser communication technologies.

The Low-Cost Optical Terminal

NASA’s Low-Cost Optical Terminal, located at the Goddard Space Flight Center in Maryland, serves as a ground station for laser communications testing. It uses mostly commercial off-the-shelf parts, making it more cost-effective and scalable for replication. The successful integration of Fibertek’s technology into the Low-Cost Optical Terminal demonstrates the effectiveness of using commercial components in laser communication systems. This ground station will serve as a template for future ground stations, further advancing laser technologies for space missions.

Predictions and Recommendations for the Industry

Based on the key points discussed above, several predictions and recommendations can be made for the future of laser communications in the space industry:

  1. Increased Adoption of Laser Communications: As the advantages of laser communications become more apparent, there will be a significant increase in the adoption of this technology in future space missions. Laser communications systems will become the standard for transmitting high-definition data and enabling faster exploration and discovery beyond Earth.
  2. Continued Collaboration with Small Businesses: NASA’s engagement with small businesses like Fibertek Inc. is crucial for the development and advancement of laser communication technologies. It is recommended that NASA continues to foster these partnerships to ensure a robust domestic supply chain and encourage innovation in the industry.
  3. Exploring Commercial Off-The-Shelf Solutions: The success of the Low-Cost Optical Terminal demonstrates the potential of using commercial off-the-shelf parts in laser communication systems. Future ground stations should consider utilizing these cost-effective solutions to promote scalability and replication.
  4. Investment in Research and Development: Continued investment in research and development is essential to further improve laser communication technologies. Funding programs like NASA’s Small Business Innovation Research Program play a vital role in supporting innovative technologies and advancing agency missions.


The future of laser communications in space missions looks promising. NASA’s collaboration with private industry partners and small businesses, as demonstrated by the development of the Basestation Optical Laser Terminal, showcases the potential of laser technology in enabling greater exploration and discovery beyond Earth. With increased data rates and faster transmission times, laser communications will revolutionize space exploration and expand humanity’s knowledge of our Moon and the universe.
