Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

The Deep Space Network (DSN) has been a core operational element of NASA’s crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique scientific data from planetary bodies. The capabilities of the DSN have advanced alongside the sophistication of the missions it serves, enhancing navigation and data-handling capacities for those missions and improving the ability to obtain significant new space science. These advancements will continue into the next decade with breakthroughs in engineering performance, measurement capabilities, and the integration of cutting-edge technologies such as quantum electronics, computing, and AI-based analysis. This paper presents a survey of the most active areas of current research that are likely to drive advances in the capabilities of DSN functions and facilities.
