MARS EXPRESS MRS: Mars Gravity Measurements from Extended Mission 2010-2012

Global gravity measurements for Mars collected by the Mars Express spacecraft's Radio Science experiment between 2010-01-01 and 2012-12-31. The data covers a specific observation period from 2011-07-13T23:57:08.000 to 2011-07-14T01:46:37.500. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling the internal structure of Mars based on global gravity field data.
• Analyzing temporal variations in the Martian gravity field from time-series measurements.
• Calibrating or validating other orbital gravity datasets for Mars.
• Studying crustal thickness and lithospheric structure using gravity anomalies.

Strengths

• Data originates from a dedicated NASA space mission, the Mars Express.
• Covers a defined two-year extended mission phase from 2010 to 2012.
• Provides a specific, high-precision observation window of nearly two hours.

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.
