ROSETTA-ORBITER 67P ROSINA 2: Comet 67P Gas Data from Prelanding Phase

V2.0 of this dataset contains CODMAC level 2 science data from the COPS, DFMS, and RTOF ROSINA sensors. The data was acquired between 2014 03 29 and 2014 11 18 during the Prelanding phase of the Rosetta mission to comet 67P/CG. It was published by the National Aeronautics and Space Administration, with a last update recorded on 2026 03 13.

Use Cases

• Analyze the composition of comet 67P's coma based on mass spectrometry data.
• Study temporal variations in gas density and pressure during the Prelanding phase.
• Model cometary outgassing processes using sensor measurements from the ROSINA instrument suite.

Strengths

• Data covers a specific 8-month operational phase from March to November 2014.
• Version 2.0 indicates curation, with missing files added and corrupted files removed.
• Data originates from the authoritative Rosetta mission conducted by NASA.

Limitations

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