MARS EXPRESS MRS: Mars Global Gravity Measurements, 2010-2012

From 2010-01-01 to 2012-12-31, the Mars Express spacecraft collected Radio Science data for global gravity measurements. The National Aeronautics and Space Administration (NASA) produced this dataset, which includes a specific observation period from 2012-10-20T02:54:01.000 to 2012-10-20T06:50:54.500.

Use Cases

• Modeling the Martian gravity field based on radio science measurements.
• Analyzing temporal variations in gravity data collected during the extended mission phase.
• Correlating gravitational anomalies with surface or subsurface features on Mars.
• Calibrating or validating other orbital gravity datasets for Mars.

Strengths

• Data covers a defined two-year extended mission phase from 2010 to 2012.
• Includes a precise, high-resolution observation window of nearly four hours on 2012-10-20.
• Produced by the National Aeronautics and Space Administration, a recognized space agency.

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.
