ROSETTA-ORBITER 67P OSIWAC: Comet 67P Images from Prelanding Phase

NASA's ROSETTA-ORBITER 67P OSIWAC 4 PRL-MTP005 RDR-INF-REFL V1.0 dataset contains calibrated image data of comet 67P/Churyumov-Gerasimenko. The data was acquired by the OSIRIS Wide Angle Camera on the Rosetta spacecraft during the prelanding mission phase from July to August 2014. This version 1.0 dataset is the first release, corrected after an external peer review in September 2019.

Use Cases

• Analyzing comet surface albedo and reflectance properties based on the radiometric calibration and reflectance units.
• Studying comet morphology and geological features based on the geometric distortion corrected image data.
• Modeling comet activity and outgassing near perihelion based on the temporal coverage of the prelanding phase.
• Validating photometric correction models based on the solar and in-field stray-light corrections applied to the images.

Strengths

• Data is radiometric calibrated, geometric distortion corrected, and has solar and in-field stray-light corrections applied.
• Covers a specific one-month observation period from 2014-07-02 to 2014-08-01 during a critical mission phase.
• Dataset is versioned (V1.0) and has undergone an external peer review process.

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.
• Data may reflect temporal bias inherent to the specific prelanding observation window.
