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

NASA's Mars Express Radio Science data set provides global gravity measurements for Mars. It was collected during the extended mission phase from 2010-01-01 to 2012-12-31, with a specific record covering 2012-06-21T06:10:31.000 to 2012-06-21T08:49:04.500. The dataset is hosted on Data.gov and was last updated in March 2026.

Use Cases

• Modeling the Martian gravitational field based on global gravity measurements
• Analyzing temporal variations in gravity data collected during the extended mission phase
• Correlating gravity anomalies with surface geology or topography features mentioned in the description

Strengths

• Data originates from NASA's Mars Express mission, an authoritative source for planetary science.
• Covers a defined two-year extended mission period from 2010-01-01 to 2012-12-31.
• Provides a specific, timestamped measurement window for detailed analysis.

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.
