ROSETTA-ORBITER 67P: Prelanding Phase Gravity Measurements

Rosetta Radio Science data collected during the PRELANDING phase from 2014-01-21 to 2014-11-18. It contains global gravity measurements at comet 67P, covering a specific observation period from 2014-09-25T16:32:50.000 to 2014-09-26T00:25:10.000. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling comet mass and density based on gravity measurements.
• Analyzing temporal changes in gravitational field during the prelanding phase.
• Calibrating orbital dynamics models for spacecraft navigation.
• Studying comet 67P's internal structure from gravity data.

Strengths

• Data originates from the Rosetta orbiter mission, a major space exploration project.
• Provides a specific, high-resolution time window for gravity observations.
• Managed by the National Aeronautics and Space Administration.

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.
