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

Rosetta spacecraft 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 for a specific observation window on 2014-09-23 and 2014-09-24. It was produced 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 based on 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 endeavor.
• Covers a defined prelanding operational phase from 2014-01-21 to 2014-11-18.
• Provides a specific, high-resolution observation period for gravity measurements.

Limitations

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