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

Rosetta Radio Science data collected during the PRELANDING phase from 2014-01 21 to 2014-11-18. The dataset contains global gravity measurements at comet 67P, covering a specific observation window from 2014-08-11T07:48:25.000 to 2014-08-11T13:46:11.000. It was published by the National Aeronautics and Space Administration.

Use Cases

• Modeling the gravity field and internal structure of comet 67P based on radio science measurements.
• Analyzing temporal variations in comet gravity during the Rosetta mission's prelanding phase.
• Calibrating or validating orbital dynamics models for the Rosetta spacecraft using the precise time range data.

Strengths

• Data covers a defined prelanding phase from 2014-01-21 to 2014-11-18, providing temporal context.
• Includes a precise 5-hour 58-minute observation window for gravity measurements on 2014-08-11.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
