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

A Rosetta Radio Science dataset collected by NASA during the PRELANDING phase from 2014-01-21 to 2014-11 18. It provides global gravity measurements for comet 67P, specifically covering the period from 2014-09-22T16:43:30.000 to 2014-09-23T01:06:13.000.

Use Cases

• Modeling the internal mass distribution of comet 67P based on gravity measurements.
• Analyzing temporal gravity variations during the prelanding orbital phase.
• Calibrating radio science instruments for future deep-space missions.
• Studying comet nucleus properties like density and porosity from gravity data.

Strengths

• Data originates from the Rosetta orbiter, a flagship ESA/NASA mission.
• Covers a specific 8.4-hour period of high-resolution gravity measurements.
• Last metadata update was 2026-03-13, indicating recent platform activity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file format are unknown, which may limit suitability assessment.
