ROSETTA-ORBITER 67P ROSINA 3 PRL: Comet 67P Mass Spectrometry Data from Prelanding Phase

Data from the Prelanding phase of the Rosetta mission to comet 67P/Churyumov–Gerasimenko, collected between 2014-03-29 and 2014-11-18. It contains level 3 science data acquired by the DFMS and RTOF sensors of the ROSINA instrument. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyzing the composition of comet 67P's coma based on mass spectrometry data.
• Studying temporal variations in comet outgassing during the Prelanding mission phase.
• Calibrating or validating mass spectrometry models using the enhanced mass scale provided in version 2.0.
• Comparing molecular abundances detected by the DFMS and RTOF sensors.

Strengths

• Data covers a defined 8-month operational period during the critical Prelanding phase.
• Version 2.0 includes an enhanced mass scale with 4 digits after the decimal for selected masses.
• Corrupted files have been removed in this version, improving data integrity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
