MARS EXPRESS PHOBOS MRS: Phobos Gravity Measurements from 2013

Mars Express Radio Science data was collected by the National Aeronautics and Space Administration during the extended mission phase from 2013-01-01 to 2014-12-31. The specific gravity measurement data for the Martian moon Phobos covers a two-hour observation window on 2013-12-30.

Use Cases

• Modeling the gravitational field of Phobos based on radio science measurements.
• Analyzing spacecraft trajectory perturbations for celestial mechanics studies.
• Estimating the mass and density of Phobos based on gravity data.
• Studying time-series signal data from deep-space radio science experiments.

Strengths

• Data originates from the National Aeronautics and Space Administration, a primary space science authority.
• The temporal coverage is precisely defined, with a specific two-hour observation period on 2013-12-30.
• The dataset is part of a defined mission phase (extended mission 4) from 2013-2014.

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.
