ROSETTA-ORBITER 67P: Radio Science Gravity Data from Extension 1 Phase

A Rosetta Radio Science data set collected during the ROSETTA EXTENSION 1 phase from 2016-01-01 to 2016-04-05. It contains global gravity measurements at comet 67P/Churyumov–Gerasimenko, covering the specific time period 2016-02-09T14:38:15.000 to 2016-02-09T22:22:30.500. The dataset is provided by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling the internal mass distribution of comet 67P based on global gravity measurements.
• Analyzing temporal variations in the comet's gravity field during the close-approach phase.
• Calibrating and validating radio science instrumentation and data processing techniques for deep-space missions.
• Studying the relationship between the comet's gravity field and its observed surface morphology.

Strengths

• Data originates from the Rosetta mission, a major European Space Agency (ESA) planetary science endeavor.
• Covers a specific, defined observation period of approximately 7 hours and 44 minutes on 2016-02-09.
• Focuses on global gravity, a key physical property for understanding comet structure.

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.
