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

MARS EXPRESS MRS is a Radio Science data set from NASA, collected during the Mars Express spacecraft's extended mission phase. It contains occultation measurements recorded from 2021-01-01 to 2022-12-31, with a specific sample covering 2021-01 23T09:29:41.000 to 2021-01-23T09:51:48.000. The dataset was last updated on 2026-03-13.

Use Cases

• Modeling Martian atmospheric density profiles based on occultation signal data.
• Analyzing time-series signal attenuation to study seasonal atmospheric changes on Mars.
• Validating atmospheric models for Mars using empirical radio science measurements.

Strengths

• Data originates from NASA's Mars Express mission, a credible source for planetary science.
• Covers a defined two-year time range from 2021-01-01 to 2022-12-31.
• Provides a precise timestamp for a sample measurement 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.
