The Near Infrared Spectrometer (NIRS) on Hayabusa was designed to study the mineralogy and physical properties of the surface of asteroid 25143 Itokawa. NIRS has a 64 channel InGaAs photodiode array detector and a diffraction grating combined with a prism. The detector covered wavelengths from 0.76 to 2.1 microns with a dispersion per pixel of 23.6 nm. The field of view is 0.1 x 0.1 degrees. Over 80,000 spectra were obtained from September to November 2005 at solar phase angles from 0 to 38 degrees.
The data sets listed in the table below are PDS3 legacy data sets. Once these data sets have been migrated to PDS4 they will be listed in the section above.
