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

Radio Science data from the Rosetta mission's PRELANDING phase, collected from 2014-01-21 to 2014-11-18. The dataset contains global gravity measurements for comet 67P/Churyumov–Gerasimenko, specifically covering the period from 2014-09-11T17:24:29.000 to 2014-09-12T01:05:11.000. It was published by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling the internal mass distribution and density of comet 67P based on gravity measurements.
• Analyzing temporal variations in the comet's gravitational field during the prelanding observation window.
• Calibrating instrument performance for the Rosetta Radio Science Investigation (RSI) system.
• Studying the relationship between comet shape, rotation, and gravity field anomalies.

Strengths

• Data originates from the authoritative Rosetta mission operated by ESA, with NASA as the listed organization.
• Covers a specific, critical prelanding phase from 2014-01 21 to 2014-11-18.
• Provides a focused 7.7-hour window of high-resolution gravity data from 2014-09-11 to 2014-09-12.

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.
• Description metadata is limited; actual data quality and format require manual inspection after download.
