A 1 Case-PR/ }*Rciofft.;Is Report
.A 1 case-PR/ }*rciofft.;is Report (a) This eruption site on Mauna Loa Volcano was the main source of the voluminous lavas that flowed two- thirds of the distance to the town of Hilo (20 km). In the interior of the lava fountains, the white-orange color indicates maximum temperatures of about 1120°C; deeper orange in both the fountains and flows reflects decreasing temperatures (<1100°C) at edges and the surface. (b) High winds swept the exposed ridges, and the filter cannister was changed in the shelter of a p^hoehoc (lava) ridge to protect the sample from gas contamination. (c) Because of the high temperatures and acid gases, special clothing and equipment was necessary to protect the eyes. nose, lungs, and skin. Safety features included military flight suits of nonflammable fabric, fuil-face respirators that are equipped with dual acidic gas filters (purple attachments), hard hats, heavy, thick-soled boots, and protective gloves. We used portable radios to keep in touch with the Hawaii Volcano Observatory, where the area's seismic activity was monitored continuously. (d) Spatter activity in the Pu'u O Vent during the January 1984 eruption of Kilauea Volcano. Magma visible in the circular conduit oscillated in a piston-like fashion; spatter was ejected to heights of 1 to 10 m. During this activity, we sampled gases continuously for 5 hours at the west edge. Cover photo: This aerial view of Kilauea Volcano was taken in April 1984 during overflights to collect gas samples from the plume. The bluish portion of the gas plume contained a far higher density of fine-grained scoria (ash). -

Dynamics and Control of Resistive Wall Modes with Magnetic Feedback Control Coils: Experiment and Theory
1 IAEA-CN-116 EX/P5-13 Dynamics and Control of Resistive Wall Modes with Magnetic Feedback Control Coils: Experiment and Theory M. E. Mauel, J. Bialek, A. H. Boozer, C. Cates, R. James, O. Katsuro-Hopkins, A. Klein, Y. Liu, D. A. Maurer, D. Maslovsky, G. A. Navratil, T. S. Pedersen, M. Shilov, and N. Stillits Department of Applied Physics and Applied Mathematics Columbia University, New York, NY 10027, USA e-mail contact of main author: [email protected] Abstract. Fundamental theory, experimental observations, and modeling of resistive wall mode (RWM) dynamics and active feedback control are reported. In the RWM, the plasma responds to and interacts with external current-carrying conductors. Although this response is complex, it is still possible to construct simple but accurate models for kink dynamics by combining separate determinations for the external currents, using the VALEN code, and for the plasma’s inductance matrix, using an MHD code such as DCON. These computations have been performed for wall-stabilized kink modes in the HBT-EP device, and they illustrate a remarkable feature of the theory: when the plasma’s inductance matrix is dominated by a single eigenmode and when the surrounding current-carrying structures are properly characterized, then the resonant kink response is represented by a small number of parameters. In HBT-EP, RWM dynamics are studied by programming quasi-static and rapid “phase-flip” changes of the external magnetic perturbation and directly measuring the plasma response as a function of kink stability and plasma rotation. The response evolves in time, is easily measured, and involves excitation of both the wall-stabilized kink and the RWM. -
Overview Release
Chicago Architecture Biennial’s Fourth Edition, The Available City Opens to the Public on Friday, September 17 CHICAGO (August 25, 2021) – The fourth edition of the Chicago Architecture Biennial (CAB) will open to the public on September 17, responding to an urban design framework that proposes connecting community residents, architects, and designers to develop and create spaces that reflect the needs of communities and neighborhoods. Over 80 contributors from more than 18 countries will respond to this framework through site-specific architectural projects, exhibitions, and programs across eight neighborhoods in Chicago and in the digital sphere. Curated by the Biennial’s 2021 Artistic Director—designer, researcher, and educator David Brown—The Available City will present projects and programs that ask and respond to the question of who gets to participate in the design of the city by exploring new perspectives and approaches to policies. The Available City illuminates the potential for immediate new possibilities, highlights improvisational organizers of the city, and underscores the exponential impact of small elements in aggregate. The Biennial is free and open to the public beginning on Friday, September 17. It will be on view at sites and in locations throughout the city, activated through in-person and online programming through December 18, 2021. Mayor Lori E. Lightfoot commented, “The Biennial always represents a remarkable time for our city, when residents, visitors, cultural organizations, and businesses come together to explore new ideas and potential for Chicago and cities worldwide. It is inspiring to see the projects and ideas developed by Chicago residents and the contributors highlighting the potential for vacant spaces. -

Looking for New Earth in the Coming Decade
Detection of Earth-like Planets with NWO With discoveries like methane on Mars (Mumma et al. 2009) and super-Earth planets orbiting nearby stars (Howard et al. 2009), the fields of exobiology and exoplanetary science are breaking new ground on almost a weekly basis. These two fields will one day merge, with the high goal of discovering Earth-like planets orbiting nearby stars and the subsequent search for signs of life on those planets. The Kepler mission will soon place clear bounds on the frequency of terrestrial-sized planets (Basri et al. 2008). Beyond that, the great challenge is to determine their true natures. Are terrestrial exoplanets anything like Earth, with life forms able to thrive even on the surface? What is the range of conditions under which Earth-like and other habitable worlds can arise? Every stellar system in the solar neighborhood is entirely unique, and it is almost certain that anything that can happen, will. With current and near-term technology, we can make great strides in finding and characterizing planets in the habitable zones of nearby stars. Given reasonable mission specifications for the New Worlds Observer, the layout of the stars in the solar neighborhood, and their variable characteristics (especially exozodiacal dust) a direct imaging mission can detect and characterize dozens of Earths. Not only does direct imaging achieve detection of planets in a single visit, but photometry, spectroscopy, polarimetry and time-variability in those signals place strong constraints on how those planets compare to our own, including plausible ranges in planet mass and atmospheric and internal structure. -

Apollo Over the Moon: a View from Orbit (Nasa Sp-362)
chl APOLLO OVER THE MOON: A VIEW FROM ORBIT (NASA SP-362) Chapter 1 - Introduction Harold Masursky, Farouk El-Baz, Frederick J. Doyle, and Leon J. Kosofsky [For a high resolution picture- click here] Objectives [1] Photography of the lunar surface was considered an important goal of the Apollo program by the National Aeronautics and Space Administration. The important objectives of Apollo photography were (1) to gather data pertaining to the topography and specific landmarks along the approach paths to the early Apollo landing sites; (2) to obtain high-resolution photographs of the landing sites and surrounding areas to plan lunar surface exploration, and to provide a basis for extrapolating the concentrated observations at the landing sites to nearby areas; and (3) to obtain photographs suitable for regional studies of the lunar geologic environment and the processes that act upon it. Through study of the photographs and all other arrays of information gathered by the Apollo and earlier lunar programs, we may develop an understanding of the evolution of the lunar crust. In this introductory chapter we describe how the Apollo photographic systems were selected and used; how the photographic mission plans were formulated and conducted; how part of the great mass of data is being analyzed and published; and, finally, we describe some of the scientific results. Historically most lunar atlases have used photointerpretive techniques to discuss the possible origins of the Moon's crust and its surface features. The ideas presented in this volume also rely on photointerpretation. However, many ideas are substantiated or expanded by information obtained from the huge arrays of supporting data gathered by Earth-based and orbital sensors, from experiments deployed on the lunar surface, and from studies made of the returned samples. -
