HIRES NIMS IDA: Galileo Spectral Image Cubes of Asteroid 243 Ida

17 channel spectral image cubes of asteroid 243 Ida, ranging from 0.7 to 5.2 micrometers in wavelength. The data were obtained by the Galileo spacecraft's Near Infrared Mapping Spectrometer on August 28, 1993 and radiometrically calibrated using measurements from June 28, 1996.

Use Cases

• Analyze asteroid surface composition based on spectral radiance data.
• Map mineralogical features across the asteroid's surface using multi-channel imagery.
• Validate or develop spectral unmixing algorithms for planetary remote sensing.
• Study the thermal properties of asteroids using infrared wavelength data.

Strengths

• Data originates from the Galileo spacecraft, a primary NASA mission.
• Covers 17 spectral channels across a defined wavelength range (0.7 to 5.2 µm).
• Includes radiometric calibration based on specific calibration observations.

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.
