MARS EXPRESS MRS: Radio Science Occultation Data from 2020

Radio Science data from the Mars Express spacecraft's extended mission phase. The dataset contains occultation measurements from a specific observation window on 2020-11-22. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Modeling Mars' atmospheric density profiles based on radio signal occultation data.
• Analyzing signal propagation delays to study the Martian ionosphere.
• Validating atmospheric models for Mars using time-stamped radio science measurements.
• Studying temporal changes in a specific atmospheric region from the 2020 observation.

Strengths

• Data originates from a NASA planetary science mission, Mars Express.
• Covers a precisely defined observation time from 2020-11-22T09:24:00.000 to 2020-11-22T09:46:08.500.
• Collected during the extended mission phase from 2019-01-01 to 2020-12-31, indicating operational longevity.

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.
