MARS EXPRESS MRS: Radio Science Occultation Data from 2021-2022

Mars Express Radio Science data collected by NASA during the 2021-2022 extended mission. The dataset contains occultation measurements from a specific observation window on 2021-03-24. It was last updated on the datagov platform in March 2026.

Use Cases

• Modeling atmospheric density profiles based on radio signal occultation data.
• Analyzing ionospheric electron density using the radio science measurement technique.
• Studying temporal changes in the Martian atmosphere during the 2021-2022 mission phase.

Strengths

• Data originates from NASA's Mars Express mission, a recognized space agency.
• Covers a defined two-year extended mission period from 2021-01-01 to 2022-12-31.
• Provides a precise timestamp for a specific occultation measurement 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.
