SMASS Asteroid Survey: Visual Range Spectrographic Data

The Small Main-Belt Asteroid Spectrographic Survey (SMASS) V2.1 provides spectrographic data over the visual range. The dataset was created by the National Aeronautics and Space Administration (NASA). The last recorded metadata update was on March 13, 2026.

Use Cases

• Classify asteroids based on spectral signatures mentioned in the description
• Analyze the mineralogical composition of main-belt asteroids based on visual range spectroscopy
• Train models for automated spectral classification of small asteroids

Strengths

• Data originates from the authoritative source NASA.
• The description specifies the survey covers the visual spectral range.

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 as the last update date is March 13, 2026.
