I am delighted to address the Gemini community from my new role as the Observatory’s Interim Director. I will hold this position for the next year, while the search for a perma- nent Director moves forward. As I write this (beginning of September), I have been in Hilo, Hawai‘i, for almost two months, and it’s been an exciting time. I have enjoyed work- ing with the Gemini staff, whose drive, dedication, and talent were already well known to me from when I chaired the Observatory Oversight Council on behalf of the Association of Universities for Research in Astronomy (AURA). -

Aerospace Safety Advisory Panel
Aerospace Safety Advisory Panel Annual Report for 2009 NASA AEROSPACE SAFETY ADVISORY PANEL National Aeronautics and Space Administration Washington, DC 20546 VADM Joseph W. Dyer, USN (Ret.), Chair January 15, 2010 The Honorable Charles F. Bolden, Jr. Administrator National Aeronautics and Space Administration Washington, DC 20546 Dear General Bolden: Pursuant to Section 106(b) of the National Aeronautics and Space Administration Authorization Act of 2005 (P.L. 109-155), the Aerospace Safety Advisory Panel (ASAP) is pleased to submit the ASAP Annual Report for 2009 to the U.S. Congress and to the Administrator of the National Aeronautics and Space Administration (NASA). ASAP members believe that NASA and the Administration face significant challenges for the Nation’s space program. Following the precedent set in 2008, the ASAP again pro - vides this letter report in lieu of the lengthier annual report submitted in previous years. This letter report is based on the Panel’s 2009 quarterly meetings (and public session minutes), fact-finding meetings, and formal recommendations, as well as ASAP members’ past experiences. In Section II of this report, the Panel provides a summary of key safety-related issues that the Agency confronts at this time. The most important relate to the future of the Nation’s human space flight program, and the ASAP hopes to encourage key stakeholders to immediately consider the critical decisions relating to this mission. Significant issues include human rating requirements for potential commercial and international entities, extension of Shuttle beyond the current manifest, workforce transition from the Shuttle to the follow-on program, the need for candid public communications about the risks of human space flight, and the more aggressive use of robots to reduce the risk of human exploration. -

The Double Helix Nebula: a Magnetic Torsional Wave Propagating out of the Galactic Centre
The Double Helix Nebula: a magnetic torsional wave propagating out of the Galactic centre Mark Morris1, Keven Uchida2, and Tuan Do1 1Department of Physics and Astronomy, University of California, Los Angeles, Los Angeles, CA 90095-1547, USA 2Center for Radiophysics and Space Research, Cornell University, Space Sciences Building, Ithaca, NY 14853-6801 Radioastronomical studies have indicated that the magnetic field in the central few hundred parsecs of our Milky Way Galaxy has a dipolar geometry and a strength substantially larger than elsewhere in the Galaxy, with estimates ranging up to a milligauss1-6. A strong, large-scale magnetic field can affect the Galactic orbits of molecular clouds by exerting a drag on them, it can inhibit star formation, and it can guide a wind of cosmic rays away from the central region, so a characterization of the magnetic field at the Galactic center is important for understanding much of the activity there. Here, we report Spitzer Space Telescope observations of an unprecedented infrared nebula having the morphology of an intertwined double helix. This feature is located about 100 pc from the Galaxy’s dynamical centre toward positive Galactic latitude, and its axis is oriented perpendicular to the Galactic plane. The observed segment is about 25 pc in length, and contains about 1.25 full turns of each of the two continuous, helically wound strands. We interpret this feature as a torsional Alfvén wave propagating vertically away from the Galactic disk, driven by rotation of the magnetized circumnuclear gas disk. As such, it offers a new morphological probe of the Galactic center magnetic field. -
The Idea of Sacred Time Is As Old As Human History As Well As Being Attributed to a Time Before Human History Began
The Sacred Time of 2012 By Willard G. Van De Bogart June 21, 2008 The wonderful host of rays has risen: the eye of Mitra, Varuna, and Agni: the Sun, the soul of all that moves or Immovable, has filled the heaven, the Earth and the firmament. Rig-Veda: 1, 115, 1 The idea of sacred time is as old as human history itself as well as being attributed to a time before human history began. It is a time known as the creation time. The time 2012 is thought of as the end time, the time when the world comes to an end and unimaginable catastrophes end the human race resulting in the infamous doomsday scenario and the fulfillment of the two millennia of Christian eschatology. Due to the loss of understanding of the celestial significance of the time 2012, and its relationship to human cognition, the unprecedented opportunity to be spiritually transformed is the other scenario which this paper on the sacred time of 2012 will address. 1 Sacred time is unlike the time associated with daily activities but is rather a time affiliated with a reverence for heaven and earth, honored and held in the highest esteem, and definitely not to be sullied by actions counter to the messages conveyed by actions or events considered to be a part of that sacred time when the universe was born; the creation time. Assailing or desacralizing the concept of something which is sacred is perhaps one of the greatest cultural efforts attempted by a deconstructionist point of view, or even by those who just wish to undermine or dismantle the ideological framework which allows the idea of something to become sacred. -

I too seem to be affected by this condition. Most astronomers get aperture fever. I don’t seem to have contracted that particular disease — I went from a 4 inch reflector to a 6 inch Maksutov-Cassegrain and then to a 5 inch refractor. No, I seem to have a different affliction: film format fever! I’ve been doing 35mm photography since I was in elementary school. A few years ago, I stepped up to medium format with a Mamiya 645 medium format camera.
