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

A Mars Express Radio Science data set collected by the National Aeronautics and Space Administration during the extended mission phase from 2021-01-01 to 2022-12 31. It contains occultation measurements covering a specific observation window on 2021-02-23. 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 temporal changes in the Martian ionosphere based on the specified observation time range.
• Validating atmospheric models for Mars using empirical radio science measurements.
• Studying signal propagation effects through the Martian atmosphere during spacecraft occultation events.

Strengths

• Data originates from the authoritative National Aeronautics and Space Administration.
• Covers a defined two-year mission period from 2021 to 2022.
• Includes a precise observation timestamp for a specific occultation event.

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.
