OCTOCAM , Gemini ’ s new workhorse imager and spectrograph , that will fulfill the needs of a large number of research areas in the 2020s , has a new name : SCORPIO , which stands for Spectrograph and Camera for Observations of Rapid Phenomena in the Infrared and Optical . In the words of project Principal Investigator Massimo Robberto , “ This new name captures the capabilities of the innovative and powerful future Instrument , operating over a very broad wavelength range from the visible to near-infrared light .” The instrument also features both imaging and spectroscopic capabilities , as well as fast readout modes .

Scorpio is Latin for “ scorpion ,” a primarily nocturnal invertebrate , which , like the number of channels ( wavelength windows ) available on the instrument , has eight legs . Scorpio is also the eighth sign of the zodiac , represented in the night sky by Scorpius the Scorpion — a constellation that , in the winter , passes overhead at the Gemini South telescope facility where it will be used .
This name change coincides with the instrument ’ s development moving into its Critical Design stage in May of this year . The project remains both on budget and on schedule ; it is slated for commissioning in 2022 .
What ’ s New with Visiting Instruments ?
IGRINS , a visiting cross-dispersed immersion grating near-infrared spectrometer provided by the Korea Astronomy and Space Science Institute ( KASI ) and University of Texas Austin ( UT Austin ) has proven extremely popular . This powerful and unique instrument , which can obtain both broad spectral coverage ( from 1.45 to 2.5 microns in a single exposure ) and high spectral resolu-
