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

Rosetta Radio Science data 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 interval 2014-09-19T06:02:02.000 to 2014-09-19T14:37:11.000. The dataset was last updated on 2026-03 13.

Use Cases

• Modeling the gravitational field of comet 67P based on radio science measurements.
• Analyzing temporal changes in comet gravity during the prelanding orbital phase.
• Calibrating or validating orbital dynamics models for the Rosetta spacecraft.

Strengths

• Data originates from the Rosetta mission, a major European Space Agency project with NASA involvement.
• Covers a specific and critical prelanding phase for comet 67P.
• Provides a defined temporal snapshot of gravity measurements from 2014-09-19.

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.
