ROSETTA-ORBITER: Radio Science Gravity Measurements at Comet 67P

From 2014-01-21 to 2014-11-18, the Rosetta orbiter collected radio science data during its prelanding phase at comet 67P/Churyumov–Gerasimenko. The dataset includes global gravity measurements from a specific 10.6-hour window on 2014-09-27. 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 spacecraft trajectory and orbital dynamics during the prelanding phase.
• Studying comet mass and density distribution using the global gravity data.

Strengths

• Data covers a defined 10-month prelanding phase from January to November 2014.
• Includes a precise 10.6-hour measurement window for gravity data on 2014-09 27.
• Originates from the authoritative Rosetta mission operated by NASA.

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.
