Community Outreach Host special-topic science & analysis workshops –Future NGSC workshop ideas: mid-IR observing opportunities at Gemini Integral Field Unit (IFU) opportunities at Gemini Using IRAF to reduce your Gemini data GNIRS observing & calibration NGSC at AAS meetings: booth at Seattle AAS (posters, brochures & Observing Tool demonstr.) –do same at Atlanta AAS (January 2004) NGSC presentations at U.S. institutions NGSC Webcast on Gemini 2004A Proposals Postdoc program (2 general; 3 South American) Gemini Science Meeting in 2004 (NGSC Support) U.S. Gemini SAC is NGSC’s community-based advisory council

NGSC Instrumentation Activities Mission –instrument procurement in U.S. for Gemini telescopes –analogous function in other partner countries Activities –NGSC let all the current U.S. instrument contracts –provide advice & liaison to the instrument teams –carry out management oversight CoDR, PDR, CDR, acceptance testing Quarterly Reviews release of payments only when specified milestone met –report progress to International Gemini; coordinate communications between the instrument team & Gemini

GNIRS: workhorse infrared long-slit / IFU spectrograph for Gemini South (NOAO) –Pre-shipment acceptance test completed 15 October 2003 –GNIRS shipment to Gemini South imminent –Mounting GNIRS on Gemini South planned for December 2003 –GNIRS first light planned for January 2004

U.S. Instrument Developments NICI: dual-beam coronagraphic infrared imager for Gemini South (MKIR) –NASA funded –Procurement / fabrication phase ending; integration phase beginning –December 2004 delivery planned Flamingos-2: multi-object IR spectrograph and imager (Florida) –Management Review in late January 2003 –NGSC assisting Florida personnel in project management techniques (Gaughan & Eklund) –Flamingos-2 contract approved and signed in early May –Critical Design Review took place in August –December 2005 delivery planned

US Next-Gen Gemini Sci/Inst Planning Workshop: May 29-31; Tempe, Arizona Goal: Key Gemini Science Programs for Realm –High-impact science questions / projects –What observations are needed to answer the science question? 40 participants; diverse in science interests & institutional affiliation (includes most of the U.S. Aspen delegates) & telecon preparatory discussions Four Science Breakout Groups –Stars, the Solar System, and Extra-Solar Planets (leader: J. Valenti) –Star Formation Processes and the ISM (leader: M. Meyer) –Structure and Evolution of the Milky Way and Nearby Galaxies (leader: R. Wyse) –Formation and Evolution of Distant Galaxies and the High-Redshift Universe (leader: K. Glazebrook) Written report on Tempe conclusions on Web Two briefings/discussions on Tempe results for U.S. Aspen delegates; firm up U.S. consensus

Tempe Over-Arching Questions Formation and Evolution of Planetary Systems Formation of Stars & Brown Dwarfs over the Mass Spectrum Origin of the Elements Origin of the Hubble Sequence Dark Matter and the Formation of Galaxies from Substructure Dark Energy and Cosmic Sound Reionization History of Universe Feedback from Stars & AGN on Galactic Evolution

Aspen International Gemini Next- Generation Instrumentation Meeting June 27-28, 2003; Aspen, CO Half of delegates from U.S. Half of science group chairs from U.S. Written report on science questions and instrumental requirements National Gemini Offices (NGSC) then estimated ROM costs for each instrument concept “Aspen” report submitted to Gemini Science Committee for its October meeting To be considered by Gemini Board at its November meeting

“Aspen” Instrument Summary

Open NGSC/Gemini Issues Are the science needs of U.S. community at large aperture being met by Gemini? Any issues impeding user science? Do the “Aspen” instruments represent a bright scientific future for Gemini? What are the near-term priorities for commissioning Gemini instruments? What data reduction software is most needed for U.S. Gemini users? Is there demand for both Queue and Classical observing with Gemini by our community? The U.S. Gemini SAC has discussed all these questions.
