MARS EXPRESS MRS: Radio Science Occultation Data from 2021-2022

MARS EXPRESS MRS is a Mars Express Radio Science dataset collected by the National Aeronautics and Space Administration. It contains occultation measurements from the extended mission phase, covering a specific observation period from 2021-04 25T06:41:28.879 to 2021-04-25T09:41:20.970. The dataset was last updated on 2026-03-13.

Use Cases

• Modeling Martian atmospheric density profiles based on radio signal occultation data.
• Analyzing signal propagation delays for atmospheric studies based on time-series occultation measurements.
• Validating atmospheric models using precise timestamps from the 2021 observation period.

Strengths

• Data originates from the authoritative National Aeronautics and Space Administration.
• Covers a defined extended mission period from 2021-01-01 to 2022-12-31.
• Provides precise timestamps for a specific occultation event in April 2021.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
