  1. Items pertaining to ANASAC Charges are in Blue; items pertaining to ASAC charges in Green; items of relevance to both are in Black.


18:00 Meet and Greet: Light refreshments in "Breakfast Room" off the Lobby of the Cavalier Inn


08.30 – 09.00 Light breakfast snacks

09.00 – 09.15 Welcome & charges – Tony Beasley

09.15 – 09.45 * ALMA Construction Status Mark McKinnon

09.45 – 10.15 * Science Overview and Discussion - A. Wootten

    • *ASAC Charge 1: Report on science results so far and lay the groundwork for future quantitative analysis. Highlight some outstanding science results from SV or Cycle 0 and put them in context of the fields they apply to. Assess what quantitative metrics will be available for assessing scientific impact by finding out what statistics are collected by the various Executives. Comment on whether the intersection of those sets provides sufficient information for the ASAC to evaluate quantitative measures of scientific outcomes from ALMA.

10.30 – 10.45 Break

10.45 – 11.30 Science Demonstration

    • *ASAC Charge 2: Review the goals of Science Demonstration as part of, or as a complement to, Science Verification. Should the current goal of Science Demonstration (Getting cutting-edge ALMA data out to the public) be modified, modulated, or limited now that proposals with proprietary time are being executed and the archive is about to open? How should targets for SV be chosen, announced, and publicized? If the goal is to get some ALMA data out to the public, have SV projects covered the proper spectrum of science areas?

11.30 – 12.00 NAASC Status - Al Wootten/C. Lonsdale

12.00 – 13.00 Lunch. 12.45: Meet the NAASC

13.00 - 13.30 Panel discussion session with NAASC

13.30 – 14.00 Maximizing science benefits for ALMA scientists

    • *ASAC Charge 3: How can we help those making ALMA work (JAO staff, postdocs, fellows, etc.) get some benefit for their own science?

14.00 – 14.30 Community Outreach

14.30 – 15.00 Committee feedback session (Carpenter)

15.00 – 15.15 Break

15.15 – 16.00 – John Hibbard Science Operations

16.00 – 17.00 NRAO/UVa Colloquium Speaker Jeyhan Kartaltepe, NOAO TBD

18.30 Dinner at Savour


08.30 – 09.00 Light breakfast snacks

09.00 – 09;45 ALMA Development Program – Al Wootten and Bill Randolph

    • ANASAC Charge: "In March 2010, the ASAC with input from the regional SACs put forward a comparison matrix of items which might be included in an ALMA development plan. Some of these projects are under way, studies have commenced for others. The ANASAC is requested to revisit this comparison considering the current science drivers and development projects."

09.45 – 10:30 ALMA Band 1 Science – Doug Johnstone

10.30 – 10.45 Break

10:45 – 11.30 NAASC data processing capabilities and re-processing scope – Mark Lacy

    • ASAC Charge 1. (above)

11.30 – 12.15 Discussion

12.15 – 13.30 Lunch

13.30 – 16.00 ANASAC executive session / question session; preliminary report

16.00 – 16.00 NRAO/UVa Colloquium Speaker: Michael Mumma, NASA GSFC Title: "Progress at the Frontiers of Cometary Science: Implications for Contributions of Water and Prebiotic Organics to Terrestrial Planets”

  • Abstract:
    • Viewed from a cosmic perspective, Earth is a dry planet yet its oceans are enriched in deuterium by a large factor relative to nebular hydrogen. Can comets have delivered Earth’s water? The question of exogenous delivery of water and organics to Earth and other young planets is of critical importance for understanding the origin of Earth’s water, and for assessing the possible existence of exo-planets similar to Earth. Strong gradients in temperature and chemistry in the proto-planetary disk, coupled with dynamical models, imply that comets from the Oort Cloud and Kuiper Disk reservoirs should have diverse composition. The primary volatiles in comets (ices native to the nucleus) provide the preferred metric, and taxonomies based on them are now beginning to emerge [1, 2, 3]. The measurement of cosmic parameters such as the nuclear spin temperatures for H2O, NH3, and CH4, and of enrichment factors for isotopologues (D/H in water and hydrogen cyanide, 14N/15N in CN and hydrogen cyanide) provide additional important tests for the origin of cometary material. I will provide an overview of these aspects, and their implications for the origin of Earth’s water and prebiotic organics. I will also touch on compositional issues that can be addressed with ALMA and other emerging astrophysical observatories.
