Mars Express Radio Science Occultation Data from Extended Mission 2021-2022

Mars Express Radio Science occultation measurements collected by NASA during the extended mission phase from 2021-01-01 to 2022-12-31. The dataset includes a specific time series from 2021-04 04T09:56:17.200 to 2021-04-04T10:31:31.899. It was last updated on the datagov platform in March 2026.

Use Cases

• Modeling Martian atmospheric density profiles based on occultation signal data.
• Analyzing temporal variations in the Martian ionosphere based on the time-series measurements.
• Validating atmospheric models for Mars using radio science data from the Mars Express mission.

Strengths

• Data originates from the authoritative NASA Mars Express mission.
• Covers a defined two-year extended mission period from 2021 to 2022.
• Provides a precise time-stamped measurement window for a specific occultation event.

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.
