MARS EXPRESS MRS: Radio Science Occultation Data from 2020

Mars Express Radio Science data collected during a specific occultation event on 2020-12 13. This dataset from NASA's extended mission phase covers measurements from 2020-12-13T15:22:58.100 to 2020-12-13T15:45:06.750. It was last updated on the Data.gov platform in March 2026.

Use Cases

• Modeling Martian atmospheric density profiles based on radio signal occultation measurements.
• Analyzing signal propagation time-series data for atmospheric structure studies.
• Validating orbital and atmospheric models using precise timestamps from the 2020 observation window.

Strengths

• Data originates from NASA, a leading space agency.
• Covers a precisely defined observation window of approximately 22 minutes.
• Part of the Mars Express extended mission from 2019-01-01 to 2020-12-31.

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.
