MARS EXPRESS MRS: Radio Science Occultation Data from 2022

MARS EXPRESS MRS 1/2/3 EXTENDED MISSION 8 4247 V1.0 is a Mars Express Radio Science dataset from NASA. It contains occultation measurements collected during the extended mission phase from 2021-01-01 to 2022-12-31, with a specific observation window on 2022-05-08. The dataset was last updated on the platform in March 2026.

Use Cases

• Modeling Martian atmospheric density profiles based on radio signal occultation data.
• Analyzing temporal changes in the Martian ionosphere based on the 2021-2022 mission phase.
• Calibrating radio science instruments for planetary missions using the specific 2022-05-08 observation event.

Strengths

• Data originates from the authoritative NASA Mars Express mission.
• Covers a defined two-year extended mission phase from 2021-01-01 to 2022-12-31.
• Provides a precise timestamp for a specific occultation event on 2022-05-08.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• Description metadata is limited; actual data quality requires manual inspection after download.
