ROSETTA-ORBITER 67P: Radio Science Gravity Measurements During Prelanding Phase

The comet 67P/Churyumov–Gerasimenko is the subject of this global gravity measurement dataset collected by the Rosetta spacecraft's Radio Science Investigation (RSI) instrument. Data was gathered during the PRELANDING phase from 2014-01 21 to 2014-11-18, with a specific measurement window on 2014-08-22T13:10:05.000 to 2014-08-22T18:30:12.000. The dataset is provided by the National Aeronautics and Space Administration.

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 approach phase.
• Calibrating radio science instrumentation and methods for future small-body missions.
• Studying the relationship between a comet's surface features and its gravitational signature.

Strengths

• Data originates from the Rosetta mission, a flagship European Space Agency project with NASA involvement.
• Covers a defined prelanding operational phase from 2014-01-21 to 2014-11-18.
• Provides a specific, high-resolution time window for gravity measurements on 2014-08-22.

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.
