MARS EXPRESS MRS: Mars Gravity Measurements from 2010-2012

From 2010-01-01 to 2012-12-31, the Mars Express spacecraft collected radio science data for global gravity measurements. The data was produced by the National Aeronautics and Space Administration and includes a specific measurement interval from 2012-07-06T09:44:56.000 to 2012-07-06T13:31:28.500. This dataset represents the extended mission phase of the Mars Express Radio Science (MaRS) investigation.

Use Cases

• Modeling the internal structure of Mars based on global gravity field data.
• Analyzing temporal variations in the Martian gravity field from radio science measurements.
• Calibrating or validating other orbital gravity datasets for Mars.
• Studying the dynamics of the Mars Express spacecraft orbit using Doppler tracking data.

Strengths

• Data covers a defined two-year extended mission phase from 2010 to 2012.
• Includes a precise, high-resolution measurement interval of approximately 3.8 hours on 2012-07-06.
• Produced by a major space agency, the National Aeronautics and Space Administration.

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.
