MARS EXPRESS PHOBOS MRS: Phobos Gravity Measurements from 2013

Mars Express Radio Science data collected by NASA between 2013-01-01 and 2014-12-31. The dataset contains Phobos gravity measurements from a specific observation period on 2013-12-27T22:42:15.000 to 2013-12-28T00:20:03.500.

Use Cases

• Modeling the gravitational field of Phobos based on radio science measurements
• Analyzing spacecraft trajectory perturbations for gravity science
• Estimating the mass and density of Phobos based on gravity data
• Studying temporal variations in gravitational measurements during the observation window

Strengths

• Data originates from a NASA spacecraft mission, suggesting authoritative source quality.
• The temporal coverage is precisely defined for the gravity measurement event.

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.
