MARS EXPRESS MRS: Radio Science Occultation Data from 2020

Mars Express Radio Science data collected during the extended mission phase from 2019-01-01 to 2020-12-31. The dataset is an occultation measurement covering the specific time interval 2020-09-14T23:17:54.000 to 2020-09-14T23:40:02.500. It was published by the National Aeronautics and Space Administration and last updated on the datagov platform in March 2026.

Use Cases

• Analyzing Martian atmospheric density and pressure profiles based on radio signal occultation data.
• Studying ionospheric electron density variations using the radio science measurement technique.
• Validating atmospheric models for Mars based on time-series data from a specific occultation event.

Strengths

• Data covers a specific, well-defined occultation event on 2020-09-14.
• Originates from the National Aeronautics and Space Administration, a recognized space agency.
• Dataset has a defined temporal coverage for the extended mission phase (2019-2020).

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.
• Description metadata is limited; actual data quality requires manual inspection after download.
