MARS EXPRESS MRS: Radio Science Occultation Data from 2022

MARS EXPRESS MRS 1/2/3 EXTENDED MISSION 8 4296 V1.0 is a Mars Express Radio Science data set collected by the National Aeronautics and Space Administration. It contains occultation measurements from the extended mission phase between 2021-01-01 and 2022-12-31, with a specific observation period on 2022-06-17. The dataset was last updated on the datagov platform in March 2026.

Use Cases

• Modeling Martian atmospheric density profiles based on radio occultation measurements.
• Analyzing signal propagation delays to study the ionosphere of Mars.
• Validating atmospheric models for Mars using time-series data from a specific observation window.

Strengths

• Data originates from the National Aeronautics and Space Administration, a recognized space agency.
• The specific observation time range is precisely defined from 2022-06-17T08:05:41.000 to 2022-06-17T10:37:53.000.
• Covers the extended mission phase from 2021-01-01 to 2022-12-31.

Limitations

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