Planetary Discoveries with Radio Science from Mariner to New Horizons

The radio communications links between spacecraft and ground stations are altered in their characteristics between the times of transmission and reception. The Doppler shift resulting from perturbations in spacecraft motion due to gravitational and non-gravitational forces, relativistic effects, as well as propagation effects in the proximity of planetary atmosphere, rings, solar corona, and interplanetary plasma are carefully examined by Radio Scientists for important physical phenomena. From the early Mariner missions five decades ago to the latest New Horizons encounter with Pluto/Charon, planetary interiors, atmospheres, surfaces, and rings have been investigated and characterized, along with precision measurements exploring the sun and aspects of fundamental physics. We report on discoveries made via planetary spacecraft Radio Science techniques with NASA and international missions and the Deep Space Network. The technological evolution is outlined leading to the latest uplink radio occultations as well as future concepts.
