Mars Express MRS: Radio Science Occultation Data from 2021-2022

Mars Express Radio Science data collected by NASA during the extended mission phase from 2021-01-01 to 2022-12-31. The dataset contains occultation measurements, with a specific example covering the time period 2021-02-11T07:34:57.000 to 2021-02-11T07:57:05.349.

Use Cases

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

Strengths

• Data originates from the authoritative NASA Mars Express mission.
• Covers a defined two-year extended mission period from 2021 to 2022.
• Contains specific occultation measurement timestamps, indicating precise data collection.

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.
