ROSETTA-ORBITER 67P ROSINA 3 EXT3: Comet 67P Mass Spectrometry Data

Mass spectrometry science data from the Rosetta mission's ROSINA instrument, specifically the DFMS and RTOF sensors. The data was collected between 2016-06-28 and 2016-06-30 during the Extension phase 3 of the mission to comet 67P/Churyumov–Gerasimenko. Version 2.0 of this dataset features an enhanced mass scale for selected masses and improved offset removal, with corrupted files removed.

Use Cases

• Analyze the chemical composition of comet 67P's coma based on mass spectrometry data.
• Study temporal variations in gas density and composition during the specified mission phase.
• Validate and improve mass calibration models for spaceborne spectrometers based on the enhanced mass scale.

Strengths

• Data is from the European Space Agency's Rosetta mission, a major planetary science endeavor.
• Version 2.0 includes specific improvements to mass scale precision and data cleaning.

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.
