The Strategic Scientific Plan also outlines Gemini’s ambition to replace the Gemini North secondary mirror with an adaptive sec- ondary mirror in order to enable ground-layer adaptive optics. Time-domain science will be supported not only by improved operations, but also with new Python-based data reduc- tion packages (DRAGONS) and the availability of SCORPIO — the facility 8-channel imager/ spectrograph being developed by PI Massimo Robberto (Space Telescope Science Institute), Southwest Research Institute, the Spanish pri- vate technological company FRACTAL, and Johns Hopkins University. Finally, the Strategic Scientific Plan advocates for continued sup- port for high-demand, high-impact visiting instruments as a cost-effective way to provide new instrumentation. Looking forward to the coming months, Gem- ini users can expect a number of new (and re- turning) capabilities at both telescopes. ZOR- RO was successfully commissioned on Gemini South in May/June, and will be offered as a visiting instrument during the 2020A semester (see the article on ZORRO commissioning on page 14 of this issue); this dual-channel optical speckle imager (PI Steve Howell, NASA Ames) July 2019 is the twin of ‘Alopeke at Gemini North. Also in May, the initial tests for MAROON-X commis- sioning at Gemini North went smoothly, and final commissioning is planned. MAROON-X (PI Jacob Bean, University of Chicago) is a visiting instrument for high-resolution and high-stabil- ity spectroscopy designed to detect Earth-size planets in the habitable zones of mid- to late-M dwarfs via radial velocity signatures. Finally, Gemini users will be happy to hear that negotiations are underway with KASI and the University of Texas to bring the high- resolution near-infrared spectrograph IGRINS back to Gemini South as a visiting instrument in 2020. Look for our 2020A Call for Proposals in August for the full set of facility and visiting instrument capabilities. By the time this article is in press, I’ll have es- caped the Tucson summer for an extended visit to Hilo and a chance to meet the Gemini Users’ Committee. Wishing all clear skies, like we experienced during the July 2nd eclipse! Jennifer Lotz is the Gemini Observatory Director. She can be reached at: [email protected] GeminiFocus 3
