MARS EXPRESS MRS: Mars Global Gravity Data from Extended Mission

National Aeronautics and Space Administration's Mars Express Radio Science dataset provides global gravity measurements for Mars. The data was collected during the extended mission phase from 2010-01-01 to 2012-12-31, with a specific record covering 2012-05 22T12:59:04.000 to 2012-05-22T14:40:57.500.

Use Cases

• Modeling the internal structure and composition of Mars based on gravity field data.
• Analyzing temporal variations in the Martian gravitational field from time-series measurements.
• Calibrating and validating orbital dynamics models for the Mars Express spacecraft.
• Studying crustal thickness and lithospheric support on Mars from gravity anomalies.

Strengths

• Data originates from the authoritative space agency, National Aeronautics and Space Administration.
• Covers a defined two-year extended mission period from 2010-01-01 to 2012-12-31.
• Provides global gravity measurement coverage for Mars.

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.
