Space is an extreme environment and as a result, unmanned and manned missions rely on the operations of the spacecraft/space habitat, and/or the health of the astronaut(s) in that extreme setting for the success of the mission and the safe return to Earth of the astronauts. Advances in Internet of Things (IoT) enabled sensor devices, Big Data pipelines and artificial intelligence (AI) present new opportunities for real-time monitoring of various spacecraft/space habitat equipment (i.e., hardware), systems (i.e., software) and the environment along with human health. While the Big Data pipeline and AI could exist solely on the spacecraft/space habitat, the provision of a communication network with suitable bandwidth, enables the transmission of raw and derived data streams for additional processing, review and research on Earth. It also provides a different layer of redundancy for onboard AI systems. Free space optical communication links (e.g., laser communication) can support greater bandwidth for exchanging space health data than classic RF communication links. Therefore, the extra provided bandwidth makes these emerging technologies excellent candidates for supporting shorter response times to urgent adverse health situations in space. The lower latency experienced in the exchange of space health data using laser transceivers can further improve the security and well-being of astronauts as well as space occupants, which are considered essential components for successful and scalable manned space missions. That transmission to Earth is at risk of cyber at-tack. In addition, to transmit data through Space, one must consider the jurisdiction and relevant bodies to oversee data traffic management in Space. In this work, we discuss the role of Space Traffic Management (STM) in improving the reliability and security of optical space communication links. Specifically, we discuss different cyber threats that adversely affect the real-time delivery of space health data that are communicated over such links. Furthermore, we propose a series of security controls that any practical Space Traffic Management scheme must take into consideration to ensure the reliability and safety of optical communicating parties/links beyond Low Earth Orbit (LEO).
