GNIRS was built by NOAO in Tucson, Arizona and delivered to Cerro Pachon in late October 2003. Commissioning of the majority of the modes took place in stages during 2004.  GNIRS was first made available for science use in 2004B. The instrument was damaged in 2007 while at Cerro Pachon and was repaired at Gemini North. Since 2010 it has been available for use on the Gemini North telescope.

Comparison of the central portions of the sparse NGC 1600 galaxy group (right) with the dense Coma Cluster (left) which is at least 10 times more massive than the NGC 1600 group. The two closest companion galaxies of NGC 1600 (NGC 1601 and NGC 1603), are nearly 8 times fainter than NGC 1600 (center of right image). The Coma Cluster contains over 1,000 known galaxies. Both images are from the Second Palomar Observatory Sky Survey.
