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

Rosetta Radio Science data collected during the PRELANDING phase from 2014-01 21 to 2014-11-18. This dataset provides global gravity measurements for comet 67P/Churyumov–Gerasimenko, specifically covering a 2.5-hour observation window on 2014-08-30. The data originates from NASA and was last updated in the catalog on 2026-03-13.

Use Cases

• Modeling the gravitational field and mass distribution of comet 67P based on radio science measurements.
• Analyzing temporal changes in comet gravity during the Rosetta mission's prelanding phase.
• Calibrating or validating simulation models of small body dynamics using the specified observation time range.

Strengths

• Data covers a defined 10-month prelanding phase from 2014-01-21 to 2014-11-18.
• Provides a precise 2.5-hour observation window for gravity measurements on 2014-08-30.
• Originates from the authoritative Rosetta mission and is provided by NASA.

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.
• Description metadata is limited; actual data quality requires manual inspection after download.
