MARS EXPRESS MRS: Mars Global Gravity Measurements from Extended Mission

A Mars Express Radio Science dataset providing global gravity measurements for the planet Mars. The data was collected by the National Aeronautics and Space Administration during the extended mission phase from 2010-01-01 to 2012-12-31, with a specific time slice from 2012-11 05T02:37:55.000 to 2012-11-05T06:47:25.500.

Use Cases

• Modeling the Martian gravitational field based on radio science measurements.
• Analyzing temporal variations in gravity data collected during the extended mission phase.
• Studying the internal structure and composition of Mars based on global gravity data.
• Calibrating or validating other orbital or geophysical models of Mars.

Strengths

• Data originates from the National Aeronautics and Space Administration, a primary space agency.
• Covers a defined two-year extended mission period from 2010 to 2012.
• Provides a specific, high-precision time range for a data subset.

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.
