MARS EXPRESS MRS: Radio Science Occultation Data from 2020

Mars Express Radio Science data collected by NASA during the extended mission phase from 2019-01-01 to 2020-12 31. The specific occultation measurement covers the time period 2020-12-04T21:48:05.500 to 2020-12-04T22:10:13.500. The dataset was last updated on the platform in March 2026.

Use Cases

• Modeling Martian atmospheric density profiles based on radio signal occultation data.
• Analyzing temporal variations in the Martian ionosphere based on the specified measurement time window.
• Validating atmospheric models for Mars using precise radio science measurements from the extended mission.

Strengths

• Data originates from the authoritative NASA Mars Express mission.
• Covers a specific, precisely timed occultation event on 2020-12-04.
• Dataset was updated on the platform in March 2026, suggesting maintained metadata.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
