About
John Segui is a leading researcher in deep space communications and delay-tolerant networking (DTN), with a focus on enabling reliable data transfer for robotic and human exploration of Mars. His seminal work on the CCSDS File Delivery Protocol (CFDP) provides a rigorous performance evaluation of latency and storage requirements for interplanetary file transfer services, directly supporting NASA’s Mars Network missions, including the 2005 Mars Reconnaissance Orbiter and the 2009 Mars Telecommunications Orbiter. This foundational study, cited 16 times, remains a key reference for spacecraft data management. Segui further advanced the field by demonstrating how DTN can manage relay data from multiple landed assets—such as the Mars Exploration Rovers—through orbiting satellites like Mars Odyssey and Mars Express. His 2006 paper on spacecraft data and relay management, with 10 citations, highlights the practical benefits of relay satellites for deep space environments, reducing the need for direct Earth communication. Segui’s contributions are critical to the architecture of future Mars missions, ensuring robust, efficient data relay across vast distances.
