S-Band Occultation

NSSDCA ID: 1971-051A-08

Mission Name: Mariner 9
Principal Investigator:Dr. Arvydas J. Kliore


The Doppler shift of the S-band telemetry signal during occultation of the spacecraft by Mars provided the vertical distribution of the index of refraction of the Martian atmosphere. These data yield the vertical distribution of neutral and ionized species.

Alternate Names

  • Mariner9/S-BandOccultation
