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

Rosetta Radio Science data collected during the PRELANDING phase from 2014-01-21 to 2014-11-18. Global Gravity measurements at comet 67P cover the specific time interval 2014-08-18T23:34:55.000 to 2014-08-19T01:41:47.500. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling the gravitational field of comet 67P based on radio science measurements.
• Analyzing spacecraft trajectory perturbations for comet mass estimation.
• Studying temporal variations in comet activity during the prelanding observation phase.

Strengths

• Data originates from the Rosetta orbiter mission, a primary source for comet 67P.
• Covers a defined 10-month prelanding phase from January to November 2014.
• Provides a specific 2-hour measurement window for detailed gravity analysis.

Limitations

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