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

Rosetta Radio Science data collected during the PRELANDING phase from 2014-01-21 to 2014-11 18. It contains global gravity measurements for comet 67P/Churyumov–Gerasimenko, specifically covering a period on 2014-08-20. 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 gravity measurements.
• Analyzing temporal variations in the comet's gravity field during the prelanding approach phase.
• Calibrating or validating radio science instrumentation and methods for deep space missions.
• Studying the relationship between a comet's gravity field and its observed shape and surface features.

Strengths

• Data originates from the authoritative Rosetta mission operated by the National Aeronautics and Space Administration.
• Covers a specific and critical prelanding operational phase from 2014-01-21 to 2014-11-18.
• Provides a focused gravity measurement window on 2014-08-20T10:00:35.000 to 2014-08-20T13:04:58.000.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• The license is listed as 'other-license-specified', requiring manual inspection of terms.
