ROSETTA-ORBITER: Gravity Measurements at Comet 67P During Prelanding Phase

A Rosetta Radio Science data set collected during the PRELANDING phase from 2014-01 21 to 2014-11-18. It contains global gravity measurements at comet 67P, covering a specific time interval from 2014-10-16T15:23:45.000 to 2014-10-17T01:16:08.500. The dataset was published by the National Aeronautics and Space Administration.

Use Cases

• Modeling the internal mass distribution of comet 67P based on gravity field data.
• Analyzing temporal variations in the comet's gravity field during the prelanding approach phase.
• Calibrating and validating radio science instrumentation for deep space missions.
• Comparing gravitational data with other Rosetta instrument measurements for a holistic comet analysis.

Strengths

• Data originates from the authoritative Rosetta mission operated by the National Aeronautics and Space Administration.
• Covers a defined prelanding observation period from 2014-01-21 to 2014-11-18.
• Provides a specific, high-resolution time window for gravity measurements on 2014-10-16/17.

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.
