ROSETTA-ORBITER 67P ROSINA 5 EXT1: Comet 67P Gas Composition Data from 2016

From January 13 to April 5, 2016, the Rosetta mission's ROSINA instrument collected mass spectrometry data on gases around comet 67P/Churyumov-Gerasimenko during its Extension Phase 1. The dataset, version 2.0, includes measurements from the DFMS and RTOF sensors, with added detections of minor species like methane and methanol. It is provided by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling comet coma chemistry based on detected molecular species.
• Analyzing temporal variations in gas density during the comet's orbit.
• Comparing relative abundances of major and minor volatile compounds.
• Validating mass spectrometry instrument performance in a space environment.

Strengths

• Data covers a specific 83-day period during a critical mission extension phase.
• Version 2.0 explicitly adds detections for 10 specific minor molecular species.
• Data originates from the authoritative Rosetta mission operated by ESA, with NASA as the provider.

Limitations

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