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

Mars Express Radio Science data collected by NASA from 2010-01-01 to 2012-12-31. The dataset provides global gravity measurements for Mars, with a specific record covering a 2.5-hour period on 2012-08-11. It was last updated on the datagov platform in March 2026.

Use Cases

• Modeling the internal structure of Mars based on global gravity measurements.
• Analyzing temporal variations in the Martian gravitational field based on time-series radio science data.
• Calibrating or validating other orbital gravity datasets for Mars.
• Studying atmospheric drag or spacecraft orbit determination using radio science techniques.

Strengths

• Data covers a defined multi-year extended mission phase from 2010 to 2012.
• Provides global gravity coverage for the planet Mars.
• Source is the authoritative space agency NASA.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
