ROSETTA-ORBITER 67P: Radio Science Gravity Measurements During Prelanding

Rosetta spacecraft radio science data collected during the PRELANDING phase from 2014-01 21 to 2014-11-18. It provides a global gravity measurement at comet 67P/Churyumov–Gerasimenko for a specific observation window on 2014-10-25. The dataset was produced by the National Aeronautics and Space Administration and last updated on 2026-03-13.

Use Cases

• Modeling the internal mass distribution of comet 67P based on global gravity measurements.
• Analyzing temporal variations in the comet's gravity field during the prelanding observation phase.
• Calibrating and validating radio science instrumentation for deep space missions.
• Studying the relationship between a comet's gravity and its surface features.

Strengths

• Data originates from the authoritative Rosetta mission operated by the National Aeronautics and Space Administration.
• Covers a defined prelanding operational phase from 2014-01-21 to 2014-11-18.
• Provides a specific global gravity measurement for comet 67P on 2014-10-25.

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.
