MARS EXPRESS: Phobos Gravity Measurements from 2013 Extended Mission

2013-12 29T01:20:45.000 to 2013-12-30T01:12:31.500 is the time coverage for this Mars Express Radio Science dataset. It contains Phobos gravity measurements collected by the National Aeronautics and Space Administration during the extended mission phase from 2013-01-01 to 2014-12-31. The dataset version is 1.0.

Use Cases

• Modeling Phobos's gravitational field based on radio science measurements
• Analyzing spacecraft trajectory perturbations for celestial mechanics based on gravity data
• Studying the internal mass distribution of Phobos based on gravity measurements

Strengths

• Data covers a specific, defined observation period from 2013-12-29 to 2013-12-30
• Collected by the National Aeronautics and Space Administration, a recognized space agency
• Dataset is versioned (V1.0), suggesting a managed release

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
