same time (Sivanandam et al., Proc. SPIE, 2018). It accomplishes this by exploiting the adaptive optics (AO) correction from both a telescope-based AO system (either the Gemini Multi-conjugate adaptive optics Sys- tem (GeMS) or the prospective Gemini North AO system) and its own additional Multiple- Object Adaptive Optics system that feeds four 1- to 2.4-micron integral field spectro- graphs (R ~ 3,000 and 8,000) that can each observe an object independently within a 2 arcminute field of view. and current telescope operations. We are very excited about working with the team on this cutting-edge new capability for Gemini, and we look forward to a fruitful collabora- tion over the next few years! MAROON-X Front End Commissioning GIRMOS is being designed and built by a Canadian consortium of universities led by the University of Toronto and the National Research Council-Herzberg Institute of As- tronomy and Astrophysics. The GIRMOS project is just getting underway, and Gemini staff were invited to participate in the Kick- off Meeting on December 4-5 at the Dunlap Institute in Toronto, Canada (Figure 3). The meeting was extremely productive, with discussions on science cases, capabilities, schedules, and responsibilities as we move into the conceptual design phase. MAROON-X is a radial velocity spectrograph being built at the University of Chicago, which is expected to have the capability to detect Earth-size planets in the habitable zones of mid- to late-M dwarf stars using the radial velocity method. The instrument is a high-resolution, bench-mounted spectro- graph designed to deliver 1 meter/second radial velocity precision for M dwarfs down to and beyond V = 16. In order for MAROON- X to come to Gemini as a visiting instrument, the team had to construct a Front End that would fit on the bottom instrument port at Gemini North, while holding the fiber that runs down to the spectrograph located in the Pier Lab below. In January, members of the GIRMOS team will come to Chile to participate in GeMS ob- serving to learn more about the AO system This Front End unit recently arrived in Hawai‘i, and was installed on the telescope for testing in December.
