Exploiting instrument platforms like the current generation of 8-10 m class telescopes represents a new era in instrument design, construction, handling, and use. Gemini’s instruments are no exception to this revolution. For example, since at least 50% of Gemini’s observing time will be queue scheduled, Cassegrain-mounted instruments will effectively remain on-line, ready to be called into service for typically months at a time with minimal delay to match observing programs with changing conditions. Furthermore, effective instrument emissivities of <1% will be needed to take advantage of the very low emissivity of the telescopes. Here we report on the technical status of the Phase I instruments, describe attention being given to the total system performance of the telescopes and instruments, and list some of the considerations going into the Phase II instrument program.
