Mars Express Radio Science: Occultation Measurements from 2020

Mars Express Radio Science data collected during the extended mission from 2019-01-01 to 2020-12-31. This specific occultation measurement covers a precise 22-minute window on 2020-09-11. The dataset originates from the National Aeronautics and Space Administration and was last updated 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 precise time-series measurement.
• Validating atmospheric models for Mars using data from the Mars Express mission's extended phase.

Strengths

• Data originates from the authoritative National Aeronautics and Space Administration.
• Covers a specific and precisely timed 22-minute occultation event on 2020-09 11.
• Part of a defined mission phase spanning two years from 2019 to 2020.

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.
