MARS EXPRESS MRS: Mars Global Gravity Measurements from 2012

Mars Express Radio Science data collected by NASA between 2010-01-01 and 2012-12-31. The dataset provides global gravity measurements for Mars, with a specific time sample from 2012-09 26T08:17:36.000 to 2012-09-26T09:54:32.500. It was last updated on the platform in March 2026.

Use Cases

• Modeling the internal structure of Mars based on global gravity field data.
• Analyzing temporal variations in Mars's gravity based on radio science measurements.
• Calibrating or validating other orbital gravity datasets for Mars.
• Studying Martian crustal and lithospheric thickness from gravity anomalies.

Strengths

• Data originates from NASA, an authoritative space agency.
• Covers a defined multi-year mission phase from 2010 to 2012.
• Provides a specific, precise timestamp for a sample measurement interval.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data volume are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
