ROSETTA-ORBITER 67P: Comet Gravity Measurements from Prelanding Phase

ROSETTA-ORBITER 67P RSI 1/2/3 PRELANDING 0323 V1.0 is a Rosetta Radio Science data set collected by the National Aeronautics and Space Administration. It contains global gravity measurements at comet 67P, recorded during the prelanding phase from 2014-01 21 to 2014-11-18. The specific time coverage for the gravity data is from 2014-09-28T16:22:20.000 to 2014-09-28T23:10:08.500.

Use Cases

• Modeling the internal mass distribution of comet 67P based on gravity field measurements.
• Analyzing temporal variations in the comet's gravity field during the prelanding approach phase.
• Calibrating or validating orbital dynamics models for the Rosetta spacecraft using radio science data.
• Studying the relationship between a comet's gravity field and its surface morphology from other mission data.

Strengths

• Data originates from a definitive space mission, the Rosetta orbiter, operated by the National Aeronautics and Space Administration.
• Covers a specific and critical mission phase (prelanding) from 2014-01-21 to 2014-11-18.
• Provides precise temporal bounds for the gravity measurements: 2014-09-28T16:22:20.000 to 2014-09-28T23:10:08.500.

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 completeness require manual inspection after download.
