ROSETTA-ORBITER ALICE: UV Spectrometer Data from Comet 67P Prelanding Phase

NASA's Rosetta Orbiter ALICE instrument captured this ultraviolet spectrometer data during the prelanding mission phase to comet 67P/Churyumov-Gerasimenko. The data covers observations from January 21, 2014, to November 18, 2014. It is classified as CODMAC level 3 data, indicating processed and calibrated scientific measurements.

Use Cases

• Analyzing the composition of comet 67P's coma and nucleus based on ultraviolet spectral data.
• Studying temporal changes in comet activity and outgassing during the prelanding approach phase.
• Calibrating and validating models of ultraviolet light interaction with cometary material.
• Comparing spectral signatures with data from other Rosetta instrument suites for multi-wavelength analysis.

Strengths

• Data originates from a flagship NASA/ESA space mission, the Rosetta Orbiter.
• Covers a specific 10-month mission phase with defined start and end dates (2014-01 21 to 2014-11-18).
• Data is processed to CODMAC level 3, suggesting calibrated scientific measurements.

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.
• Description metadata is limited; actual data quality requires manual inspection after download.
