ber 2011 to work on conceptual designs for six months. At this stage, we are exploring both fiber-fed, bench-mounted, and Cassegrain-mounted designs. on a multi-wavelength, medium-resolution spectroscope (so-called the Gemini InfraRed Optical Spectrometer (GIROS)) as part of this exploration process. An internal and external committee will hold a conceptual design review at the end of May. We expect this to lead to a down-select of a single team to carry on with the rest of the design and building of GHOS. If, however, the studies reveal that it’s simply not practical to build such an instrument for Gemini (a long fiber feed sacrificing blue throughput, or a Cassegrain instrument needing to overcome flexure), we may cancel GHOS altogether. Additionally, if two teams offer compelling evidence that the instrument can be built, but both teams need further development, we may continue the competition into the preliminary design stage. We hope to receive a finished GHOS by mid-2015, but a more definitive schedule will have to await the results of the current design studies. Our long-range plan is an extremely important activity to keep Gemini competitive, and at the same time complementary, with other existing facilities. It is also a challenging process to map out all the variables and scenarios in creating such a bright future. We anticipate receiving enough feedback from the community, in particular at the GSM in July, to optimize the process and outcome. In parallel, we are developing new communication tools to provide the user community with more regular (quarterly) updates and news which will be distributed through our National Gemini Offices. We encourage you to contact us if you have questions. As part of defining the Gemini instrumentation long-range plan, we have initiated several actions jointly with our Science and Technology Advisory Committee (see article on “STAC” in this issue). First, we have defined a proper process with inputs, steps, and outputs, which we’ve linked to various events happening this year: For example, the Gemini North Adaptive Optics workshop in June, and the Gemini Science Meeting (GSM) in July, as well as other regular governance bodies meetings. The goal is to define the scientific capabilities needed by the ob
