Mars Express MRS: Global Gravity Measurements from Extended Mission 2010-2012

Mars Express Radio Science data collected by NASA from 2010-01-01 to 2012-12-31. This dataset provides global gravity measurements for Mars, with a specific time slice from 2012 09 18T04:35:43.000 to 2012 09 18T06:12:20.500. The data is stored in HDF5 format and was last updated on the platform in 2026.

Use Cases

• Modeling the Martian gravity field based on radio science measurements.
• Analyzing temporal variations in gravity data from the specified 2012 time slice.
• Studying planetary interior structure based on global gravity coverage.
• Calibrating or validating other Mars orbital datasets using precise gravity data.

Strengths

• Data originates from NASA's Mars Express mission, an authoritative source.
• Covers a defined two-year extended mission period from 2010 to 2012.
• Provides a precise time-stamped measurement window for a specific 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.
