NAME The Radio Science Experiment for New Horizons
TYPE Radio Science
DESCRIPTION The primary purpose of the Radio Science Experiment (REX) was to investigate open questions regarding atmospheric and ionospheric structure, surface conditions, and planetary radii of both Pluto and Charon. The REX encounter with the Pluto system was focused on occultations by Pluto and Charon of an Earth-based uplink radio signal. The New Horizons high-gain antenna (HGA) remained pointed toward Earth for the duration of the occultation events, beginning and ending with the line-of-sight to Earth well above any anticipated sensible atmosphere or ionosphere. This arrangement set up three investigations at each occultation, plus a fourth gravity investigation:
