MARS EXPRESS MRS: Mars Global Gravity Data from Extended Mission

Mars Express Radio Science gravity data collected by NASA during the extended mission phase from 2010-01-01 to 2012-12 31. The dataset covers a specific observation period on 2012-12-16T06:55:05.000 to 2012-12-16T09:25:45.500.

Use Cases

• Modeling the internal structure of Mars based on global gravity measurements.
• Analyzing temporal variations in the Martian gravitational field from time-series radio science data.
• Calibrating or validating other orbital gravity datasets using this specific observation period.
• Studying the dynamics of the Mars Express spacecraft orbit using precise radio tracking data.

Strengths

• Data originates from the NASA Mars Express mission, a primary scientific source.
• Covers a defined two-year extended mission phase (2010-2012).
• Provides a precise timestamp for a specific gravity measurement observation.

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.
