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

Rosetta spacecraft radio science data collected during the PRELANDING phase from 2014-01 21 to 2014-11-18. This specific dataset provides a global gravity measurement for comet 67P/Churyumov–Gerasimenko, covering a precise 2.5-hour observation window on 2014-09-21. The data originates from NASA and was last updated in March 2026.

Use Cases

• Modeling the internal mass distribution and density of comet 67P based on 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 or activity.

Strengths

• Data originates from the authoritative Rosetta mission operated by ESA with NASA involvement.
• Covers a specific and critical prelanding phase for comet 67P from January to November 2014.
• Provides a precise global gravity measurement during a defined 2.5-hour window on 2014-09-21.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file format are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
