MARS EXPRESS MRS: Mars Global Gravity Measurements from 2012

A Mars Express Radio Science dataset collected by NASA from 2010-01-01 to 2012-12-31. It provides global gravity measurements for Mars, with a specific time record from 2012-07-01T10:53:26.000 to 2012-07-01T14:15:32.500. The dataset was last updated on 2026-03-13.

Use Cases

• Modeling the internal structure of Mars based on gravity field data.
• Analyzing temporal variations in Martian gravity based on time-series measurements.
• Calibrating orbital models for the Mars Express spacecraft based on radio science tracking.
• Studying the geophysical history of Mars through its gravitational anomalies.

Strengths

• Data covers a defined extended mission period from 2010 to 2012.
• Provides a specific, high-precision time range for a gravity measurement event.
• Originates from the authoritative NASA Mars Express mission.

Limitations

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