Mars Express Radio Science Occultation Measurements from 2021-04-25

A Mars Express Radio Science data set collected by NASA during the extended mission phase from 2021-01-01 to 2022-12-31. The data covers a specific occultation measurement time from 2021-04 25T08:54:08.000 to 2021-04-25T09:24:08.799. It was last updated on the datagov platform in March 2026.

Use Cases

• Modeling Martian atmospheric density profiles based on radio signal occultation data
• Analyzing time-series signal propagation for planetary science research
• Studying ionospheric properties of Mars using the described occultation measurements

Strengths

• Data collected by the National Aeronautics and Space Administration, a recognized space agency
• Covers a specific, well-defined measurement window of approximately 30 minutes
• Part of a defined extended mission phase spanning two years (2021-2022)

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count and file size are unknown, which may limit suitability assessment
