ROSETTA-ORBITER 67P RSI: Comet 67P Gravity Measurements from Prelanding Phase

Rosetta Radio Science data set collected by the National Aeronautics and Space Administration during the PRELANDING phase from 2014-01 21 to 2014-11-18. It contains Global Gravity measurements for comet 67P, covering a specific observation window on 2014-10-21. The dataset was last updated on 2026-03-13.

Use Cases

• Modeling comet 67P's internal mass distribution based on gravity measurements.
• Analyzing temporal variations in gravitational field during the prelanding observation phase.
• Calibrating radio science instrumentation for future deep-space missions.
• Studying the relationship between a comet's gravity and its orbital characteristics.

Strengths

• Data originates from the authoritative Rosetta mission operated by the National Aeronautics and Space Administration.
• Covers a defined prelanding phase from 2014-01-21 to 2014-11-18, with a precise gravity measurement time on 2014-10-21.

Limitations

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