ROSETTA-ORBITER 67P VIRTIS 2: Prelanding Comet Spectra from 2014

Rosetta spacecraft telemetry containing digital numbers from the VIRTIS instrument during its prelanding phase at comet 67P/Churyumov–Gerasimenko. This version 2.0 dataset, produced by NASA with a fixed EGSE software, covers observations from September 23 to October 24, 2014. The previous software version produced incomplete products, which this release corrects.

Use Cases

• Analyzing comet surface composition based on VIRTIS spectral telemetry data
• Studying temporal changes in comet activity during the prelanding observation phase
• Calibrating or validating spectral models using corrected digital number values from the fixed software

Strengths

• Data covers a specific 32-day observation window from 2014-09-23 to 2014-10-24
• Version 2.0 corrects a known software issue that produced incomplete data products in the prior version
• Produced by NASA, a recognized authority in space science data

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
