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

Rosetta spacecraft radio science data collected during the PRELANDING phase from 2014-01 21 to 2014-11-18. This dataset provides global gravity measurements at comet 67P/Churyumov–Gerasimenko, specifically covering a 1-hour 44-minute observation window on 2014-08-17. The data originates from the National Aeronautics and Space Administration and was last updated in the catalog on 2026-03-13.

Use Cases

• Modeling the internal mass distribution of comet 67P based on gravity field measurements.
• Analyzing spacecraft trajectory and orbital dynamics during the prelanding phase.
• Studying temporal variations in a comet's gravity field during close approach.
• Calibrating radio science instrumentation and methods for deep space missions.

Strengths

• Data is from a definitive source, the National Aeronautics and Space Administration.
• Covers a specific, critical prelanding observation phase from 2014-01-21 to 2014-11-18.
• Provides a focused gravity measurement window on 2014-08-17, lasting 1 hour 44 minutes.

Limitations

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