ROSETTA-ORBITER 67P RSI: Gravity Measurements During Prelanding Phase

NASA's Rosetta Radio Science data set contains gravity measurements for comet 67P collected during the PRELANDING phase from 2014-01-21 to 2014-11-18. The specific gravity measurement time range is 2014-11-15T14:35:50.000 to 2014-11-16T01:35:49.000. This dataset was last updated on 2026-03-13.

Use Cases

• Modeling comet 67P's gravitational field based on radio science measurements.
• Analyzing gravitational variations during the Rosetta mission's prelanding phase.
• Comparing gravity data with other comet observation datasets.
• Calibrating spacecraft navigation models using precise gravity measurements.

Strengths

• Data originates from the NASA Rosetta mission, a major space science project.
• Provides a specific gravity measurement time range of approximately 11 hours.
• Covers a defined prelanding phase from January to November 2014.

Limitations

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