PASCALE Spectral Data for OSIRIS-REx Asteroid Bennu Mission

Spectral library and blind test data created in support of NASA's OSIRIS-REx mission to asteroid Bennu. The data was produced by N. Bowles at the University of Oxford. The last update date is unknown.

Use Cases

• Calibrating spectral instruments based on reference library data
• Validating asteroid composition models using blind test data
• Training machine learning classifiers for spectral feature identification

Strengths

• Data is directly linked to the NASA OSIRIS-REx mission, a major planetary science endeavor.
• Created by a researcher at a recognized institution (University of Oxford).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
