MARS EXPRESS MRS: Mars Gravity Measurements from Extended Mission

MARS EXPRESS MRS 1/2/3 EXTENDED MISSION 3 3365 V1.0 is a Mars Express Radio Science dataset containing global gravity measurements. The data was collected by the National Aeronautics and Space Administration during the extended mission phase from 2010-01-01 to 2012-12-31. A specific measurement interval covers the time from 2012-12-17T02:26:18.000 to 2012-12-17T05:49:46.500.

Use Cases

• Model Mars's internal mass distribution based on global gravity measurements.
• Analyze temporal variations in gravitational field based on the specified time interval.
• Validate and refine orbital models for the Mars Express spacecraft based on radio science data.
• Study crustal and mantle density anomalies on Mars based on gravity field data.

Strengths

• Data originates from the National Aeronautics and Space Administration.
• The dataset covers a defined extended mission period from 2010-01-01 to 2012-12-31.
• A specific measurement interval is provided: 2012-12-17T02:26:18.000 to 2012-12-17T05:49:46.500.

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.
