MARS EXPRESS MRS: Mars Global Gravity Data from Extended Mission

A Mars Express Radio Science data set collected by NASA from 2010-01-01 to 2012-12-31. The data covers a specific measurement period from 2012-11-10T01:09:36.000 to 2012-11-10T04:30:09.500. It is a Global Gravity measurement from the Mars Express spacecraft's extended mission phase.

Use Cases

• Modeling the internal structure of Mars based on global gravity measurements.
• Analyzing temporal variations in Mars's gravitational field from time-series radio science data.
• Calibrating and validating other orbital gravity data sets for Mars.
• Studying the dynamics of the Mars Express spacecraft orbit using radio science tracking.

Strengths

• Data originates from a NASA planetary science mission.
• Covers a defined two-year extended mission period from 2010 to 2012.
• Provides a specific, high-precision measurement window of over 3 hours.

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.
