National Aeronautics and Space Administration, Ames Research Center, Moffett Field, CA July 2008 Moon week celebration draws hundreds of scientists BY KELLY HUMP H RIES AND MIC H AEL MEW H INNEY NASA’s Ames July 21-23 as part of a lunar landing and the future of lunar An estimated 500 scientists from “Moon Week Celebration” marking exploration. all over the country converged on the 39th anniversary of the Apollo 11 The Lunar Science Conference was co-hosted by NASA’s Lunar Science Institute, NASA’s Ames and the NASA Lunar and Planetary Science Institute, Houston. The three-day conference examined on-going lunar research and findings and looking forward to a new generation of opportunities for studies of the moon, on the moon and from NASA photos by Eric James NASA the moon. Featured speakers included NASA Ames Center Director S. Pete Worden, Lunar Science Institute Interim Direc- tor David Morrison and noted plan- etary scientist Chris McKay. Pre- sentations were also given by space entrepreneurs and a panel of young NASA scientists and engineers look- ing at innovative approaches to lunar exploration and public involvement.

After years of development and photo by Eric James NASA preparation, it took just 20 seconds to apply the shiny, aluminum coating to the glass mirror for the Stratospheric Observatory for Infrared Astronomy (SOFIA). The telescope is scheduled to begin observations in mid-2009. "The change was quite sudden and stunning. One moment, we were looking through the transparent glass mirror into its honeycomb-shaped internal structure, and then seconds later, all we saw were reflections," said Patrick Waddell, a systems engineer with the Universities Space Research Technicians at NASA’s Ames inspect the main mirror for NASA’s new airborne eye on the universe, Association (USRA), which manages which is now ready for installation after being transformed from a carefully shaped and polished piece of the SOFIA science mission for NASA. glass into a highly reflective optical component.
