About

Dr. Lena Braatz is a leading figure in the development of space-based laser communications, a field critical for enabling high-bandwidth data transmission from deep space and near-Earth orbit. Her research centers on advancing optical communication systems and establishing the international standards necessary for global interoperability. Dr. Braatz has been instrumental in shaping the future of space data systems through her work with the Interagency Operation Advisory Group (IOAG) and the Consultative Committee for Space Data Systems (CCSDS). Her most impactful contribution is her work on NASA’s Laser Communications Relay Demonstration (LCRD), where her 2023 paper detailing the mission’s early experimental results has garnered 32 citations, highlighting its importance in measuring atmospheric effects on laser links. She has also been a key driver of interoperability standards, with her 2019 and 2017 papers (14 and 12 citations, respectively) laying the groundwork for unified optical communication protocols for both near-Earth and deep-space missions. Through these efforts, Dr. Braatz is not only advancing the technology but also ensuring that future spacecraft—from robotic probes to human-rated vessels—can communicate seamlessly across the solar system.
