ROSETTA-ORBITER 67P: Radio Science Gravity Measurements Pre-Landing

From 2014-01-21 to 2014-11-18, the Rosetta orbiter collected Radio Science data during its PRELANDING phase at comet 67P. The dataset includes a specific Global Gravity measurement on 2014-08-13 between 13:51:05.000 and 19:10:41.500. It was published by the National Aeronautics and Space Administration.

Use Cases

• Modeling the gravitational field of comet 67P based on radio science measurements.
• Analyzing temporal variations in gravity during the pre-landing orbital phase.
• Calibrating or validating comet nucleus density models based on the global gravity data.

Strengths

• Data covers a defined 10-month pre-landing phase from 2014-01-21 to 2014-11-18.
• Includes a precise global gravity measurement with a ~5.3-hour observation window on 2014-08-13.
• Produced by the authoritative space agency, National Aeronautics and Space Administration.

Limitations

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