Mars Express Radio Science: Global Gravity Measurements from 2012

Global Gravity measurement data collected by the Mars Express spacecraft's Radio Science instrument. The dataset covers a specific observation period from 2012-05-03T07:42:46.000 to 2012 05-03T11:19:18.000 during the extended mission phase from 2010-01-01 to 2012-12-31. It was produced by the National Aeronautics and Space Administration and last updated on the platform in March 2026.

Use Cases

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

Strengths

• Data originates from a NASA planetary science mission, Mars Express.
• Covers a defined extended mission period from 2010 to 2012.
• Provides a specific, high-resolution observation window of over 3.5 hours on 2012-05-03.

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.
