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

NASA's Rosetta spacecraft acquired this calibrated image data of comet 67P/Churyumov-Gerasimenko using the OSIRIS Wide Angle Camera. The dataset covers the prelanding mission phase from August 1 to September 2, 2014, with radiometric and geometric corrections applied. Version 2.0 incorporates updates from a 2018 peer review, including improved documentation and data quality handling.

Use Cases

• Analyze cometary surface morphology and features based on calibrated, distortion-corrected imagery.
• Study temporal changes in comet 67P's activity during the prelanding approach phase.
• Validate radiometric calibration pipelines for spacecraft camera data.
• Assess image data quality using documented shutter and readout issue maps.

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm) and geometrically corrected.
• Dataset versioning indicates active curation, with V2.0 superseding prior deliveries after a 2018 peer review.
• Specific temporal coverage from 2014-08-01T10:00:00.000 to 2014-09 02T09:59:59.000.
• Documentation includes a science user guide with FAQ and data quality sections.

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.
