ROSETTA-ORBITER 67P: Prelanding Gravity Measurements at Comet 67P

Rosetta mission radio science data collected during the prelanding phase from 2014-01-21 to 2014-11-18. The dataset provides global gravity measurements at comet 67P/Churyumov–Gerasimenko, with a specific measurement interval from 2014-08-20T18:55:55.000 to 2014-08-21T01:32:53.000. It was published by the National Aeronautics and Space Administration.

Use Cases

• Modeling the gravitational field of comet 67P based on radio science measurements.
• Analyzing comet mass and density distribution from global gravity data.
• Studying spacecraft trajectory and orbital dynamics during the prelanding phase.

Strengths

• Data originates from the Rosetta mission, a major European Space Agency project.
• Specific measurement time range is explicitly defined from 2014-08-20 to 2014-08-21.
• Dataset is hosted on a government platform (datagov) and was last updated in 2026.

Limitations

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