MARS EXPRESS MRS: Mars Global Gravity Measurements from Extended Mission

Mars Express Radio Science data collected by NASA during the extended mission phase from 2010-01-01 to 2012 12-31. The dataset provides global gravity measurements for a specific observation period on 2012-11-11. It was last updated on the platform in 2026-03-13.

Use Cases

• Modeling the Martian gravity field based on radio science measurements.
• Analyzing temporal variations in gravity data from the specified observation period.
• Studying the internal structure and composition of Mars using gravity anomalies.
• Calibrating or validating other Mars mission datasets with precise gravity data.

Strengths

• Data originates from the authoritative NASA Mars Express mission.
• Covers a defined two-year extended mission phase from 2010 to 2012.
• Provides a specific, high-precision observation window on 2012-11-11.

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.
