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

A Rosetta Radio Science data set collected by the National Aeronautics and Space Administration during the PRELANDING phase from 2014-01 21 to 2014-11-18. It contains global gravity measurements at comet 67P, specifically covering the time period 2014-10-25T12:21:15.000 to 2014-10-25T14:39:58.500.

Use Cases

• Modeling the internal mass distribution of comet 67P based on gravity measurements.
• Analyzing temporal changes in gravitational field during the prelanding phase.
• Calibrating radio science instrumentation for future deep space missions.
• Studying comet nucleus properties through derived gravity data.

Strengths

• Data originates from the authoritative Rosetta mission operated by the National Aeronautics and Space Administration.
• Covers a specific and critical prelanding operational phase from 2014-01-21 to 2014-11-18.
• Provides a precise time window for gravity measurements on 2014-10-25.

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 requires manual inspection after download.
