Mars Express Phobos Gravity Measurements from 2013 Extended Mission

A Mars Express Radio Science dataset collected during the extended mission phase from 2013-01-01 to 2014-12-31. It contains Phobos gravity measurements covering the specific time interval 2013-12 31T20:41:40.000 to 2013-12-31T21:54:20.899. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling the gravitational field of Phobos based on radio science measurements
• Analyzing the internal mass distribution of a Martian moon based on gravity data
• Studying orbital dynamics and perturbations based on precise time-series measurements
• Calibrating or validating other remote sensing instruments for planetary science

Strengths

• Data covers a specific, precisely defined observation window of over an hour
• Originates from a NASA mission, suggesting authoritative collection methods
• Last updated in March 2026, indicating recent metadata maintenance

Limitations

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