S-Band Occultation

NSSDCA ID: 1969-014A-06

Mission Name: Mariner 6
Principal Investigator:Dr. Arvydas J. Kliore


In this experiment the changes in the frequency, phase, and amplitude of the S-band (2300 MHz) tracking and telemetry signal, immediately prior to and following the occultation of the spacecraft by the planet, were used to derive the temperature, pressure, and density of the lower gaseous atmosphere of Mars and the density of charged particles in the Martian ionosphere.
