MARS EXPRESS MRS: Radio Science Occultation Data from 2019-2020

NASA's Mars Express Radio Science data set contains occultation measurements collected during the extended mission phase from 2019-01-01 to 2020-12-31. The provided sample covers a specific event on 2020-12 25T13:49:52.200 to 2020-12-25T14:12:01.549. This dataset was last updated on 2026-03-13.

Use Cases

• Modeling Martian atmospheric density and pressure profiles based on radio occultation measurements.
• Analyzing signal propagation and refraction through the Martian atmosphere based on the time-series occultation data.
• Validating atmospheric models for Mars using precise, time-stamped radio science observations.

Strengths

• Data originates from NASA's Mars Express mission, a credible source for planetary science.
• Covers a defined two-year extended mission period from 2019-01-01 to 2020-12-31.
• Provides a precise timestamp for a specific 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.
