ROSETTA-ORBITER 67P GIADA 3 PRL PRELANDING V1.1: Cometary Particle Data

Version V1.1 of the GIADA instrument's Prelanding Phase data supersedes the previous V1.0 release, addressing an issue in some tables and all scientific RIDs. The data covers the period from 21 January 2014 to 20 November 2014, starting after Rosetta's Deep Space Hibernation and including the Re-Commissioning of the Payload and the GIADA scientific phase beginning 7 May 2014. This dataset was published by the National Aeronautics and Space Administration.

Use Cases

• Characterize the dust and particle environment of comet 67P/Churyumov-Gerasimenko based on the GIADA instrument's scientific phase.
• Analyze temporal changes in cometary activity during the Prelanding Phase from January to November 2014.
• Validate and compare results with the superseded V1.0 dataset after the correction of table issues.
• Study the commissioning and performance of spaceborne scientific payloads during mission reactivation.

Strengths

• Dataset is versioned, with V1.1 explicitly superseding V1.0 after fixing issues.
• Covers a defined 10-month Prelanding Phase from 21 January 2014 to 20 November 2014.
• Specific start date (7 May 2014) is provided for the GIADA scientific characterization phase.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-03-13.
