MARS EXPRESS MRS: Mars Global Gravity Measurements from 2012

Mars Express Radio Science data collected by NASA between 2010 and 2012. The dataset provides global gravity measurements for Mars, with a specific observation period from 2012-05-01T07:49:36.000 to 2012-05-01T10:03:16.500. It originates from the Mars Express spacecraft's extended mission phase.

Use Cases

• Modeling the internal structure of Mars based on global gravity field data.
• Analyzing temporal variations in Martian gravity from time-series radio science measurements.
• Calibrating orbital models for the Mars Express spacecraft using precise gravity data.
• Studying the distribution of mass and density within the Martian crust and mantle.

Strengths

• Data collected by NASA, a leading space agency.
• Covers a defined two-year extended mission from 2010-01-01 to 2012-12-31.
• Provides a specific, high-precision observation window of over two hours.

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.
