| DESCRIPTION |
The Near Infrared Spectrometer (NIRS3) onboard the Hayabusa2 spacecraft was a point spectrometer that operated over the effective wavelength range of 1.8-3.2 micrometers with a 0.1 degree field-of-view. The "3" of the designation "NIRS3" comes from "3 micrometers". Around 3 micrometers, there are absorption lines of minerals with hydroxyl groups (OH). The primary goal of NIRS3 was to map the distribution of hydrated minerals on the target near-Earth asteroid (162173) Ryugu.
