Mars Express MRS: Radio Science Occultation Data from 2021-2022

National Aeronautics and Space Administration collected this Mars Express Radio Science dataset during the extended mission phase from 2021-01-01 to 2022-12 31. It is an occultation measurement covering a specific time interval on 2021-04-09. The dataset was last updated on the platform in March 2026.

Use Cases

• Modeling Martian atmospheric density profiles based on radio signal occultation data.
• Analyzing signal propagation anomalies for planetary atmospheric studies.
• Validating orbital and atmospheric models for Mars using time-series radio science measurements.

Strengths

• Data originates from the authoritative source National Aeronautics and Space Administration.
• Covers a defined two-year mission period from 2021-01-01 to 2022-12-31.
• Contains a specific, timestamped occultation measurement from 2021-04-09.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
