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

Mars Express Radio Science data was collected by the National Aeronautics and Space Administration during the extended mission phase from 2021-01-01 to 2022-12-31. The dataset contains occultation measurements, with a specific sample time range from 2021-04-03T05:59:47.399 to 2021-04-03T06:35:47.750. It was last updated on the datagov platform in March 2026.

Use Cases

• Analyzing Martian atmospheric density profiles based on occultation measurements.
• Studying signal propagation delays for planetary radio science experiments.
• Validating atmospheric models using time-series radio science data from a specific mission phase.

Strengths

• Data originates from the National Aeronautics and Space Administration, a leading space agency.
• Covers a defined two-year mission phase from 2021-01-01 to 2022-12-31.
• Includes a specific, documented measurement time range for a sample 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.
