Mars Express MRS: Radio Science Occultation Data from 2019-2020

NASA's Mars Express Radio Science (MRS) dataset contains occultation measurements collected during the extended mission phase from 2019-01-01 to 2020-12-31. The provided sample data covers a specific observation window on 2020-11 26. This data is sourced from the Data.gov platform and was last updated in March 2026.

Use Cases

• Modeling atmospheric density profiles based on radio signal occultation data.
• Analyzing ionospheric electron density using the described radio science measurements.
• Studying temporal changes in the Martian atmosphere during the 2019-2020 extended mission period.

Strengths

• Data originates from the authoritative NASA Mars Express mission.
• Covers a defined two-year extended mission period from 2019-01-01 to 2020-12-31.
• Provides a precise timestamp for a sample occultation event (2020-11-26T11:12:12.399 to 2020-11-26T11:34:20.549).

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.
