Solar and Space Physics: a Science for a Technological Society
Solar and Space Physics: A Science for a Technological Society The 2013-2022 Decadal Survey in Solar and Space Physics Space Studies Board ∙ Division on Engineering & Physical Sciences ∙ August 2012 From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outwards to a region far beyond Pluto where the Sun’s influence wanes, advances during the past decade in space physics and solar physics have yielded spectacular insights into the phenomena that affect our home in space. This report, the final product of a study requested by NASA and the National Science Foundation, presents a prioritized program of basic and applied research for 2013-2022 that will advance scientific understanding of the Sun, Sun- Earth connections and the origins of “space weather,” and the Sun’s interactions with other bodies in the solar system. The report includes recommendations directed for action by the study sponsors and by other federal agencies—especially NOAA, which is responsible for the day-to-day (“operational”) forecast of space weather. Recent Progress: Significant Advances significant progress in understanding the origin from the Past Decade and evolution of the solar wind; striking advances The disciplines of solar and space physics have made in understanding of both explosive solar flares remarkable advances over the last decade—many and the coronal mass ejections that drive space of which have come from the implementation weather; new imaging methods that permit direct of the program recommended in 2003 Solar observations of the space weather-driven changes and Space Physics Decadal Survey.

Sources for the History of Space Concepts in Physics: from 1845 to 1995
CBPF-NF-084/96 SOURCES FOR THE HISTORY OF SPACE CONCEPTS IN PHYSICS: FROM 1845 TO 1995 Francisco Caruso(∗) & Roberto Moreira Xavier Centro Brasileiro de Pesquisas F´ısicas Rua Dr. Xavier Sigaud 150, Urca, 22290–180, Rio de Janeiro, Brazil Dedicated to Prof. Juan Jos´e Giambiagi, in Memoriam. “Car l`a-haut, au ciel, le paradis n’est-il pas une immense biblioth`eque? ” — Gaston Bachelard Brief Introduction Space — as other fundamental concepts in Physics, like time, causality and matter — has been the object of reflection and discussion throughout the last twenty six centuries from many different points of view. Being one of the most fundamental concepts over which scientific knowledge has been constructed, the interest on the evolution of the ideas of space in Physics would per se justify a bibliography. However, space concepts extrapolate by far the scientific domain, and permeate many other branches of human knowledge. Schematically, we could mention Philosophy, Mathematics, Aesthetics, Theology, Psychology, Literature, Architecture, Art, Music, Geography, Sociology, etc. But actually one has to keep in mind Koyr´e’s lesson: scientific knowledge of a particular epoch can not be isolated from philosophical, religious and cultural context — to understand Copernican Revolution one has to focus Protestant Reformation. Therefore, a deeper understanding of this concept can be achieved only if one attempts to consider the complex interrelations of these different branches of knowledge. A straightforward consequence of this fact is that any bibliography on the History and Philosophy of space would result incomplete and grounded on arbitrary choices: we might thus specify ours. From the begining of our collaboration on the History and Philosophy of Space in Physics — born more than ten years ago — we have decided to build up a preliminary bibliography which should include just references available at our libraries concerning a very specific problem we were mainly interested in at that time, namely, the problem of space dimensionality. -

Weighing Uranus' Moon Cressida with the Η Ring

Weighing Uranus’ Moon Cressida with the η Ring Robert O. Chancia1 , Matthew M. Hedman1 , and Richard G. French2 1 Department of Physics, University of Idaho, Moscow, ID 83844-0903, USA; [email protected] 2 Astronomy Department, Wellesley College, Wellesley, MA 02481, USA Received 2017 June 19; revised 2017 August 9; accepted 2017 August 21; published 2017 September 20 Abstract The η ring is one of the narrow rings of Uranus, consisting of a dense core that is 1–2 km wide and a diffuse outer sheet spanning about 40 km. Its dense core lies just exterior to the 3:2 Inner Lindblad Resonance of the small moon Cressida. We fit the η ring radius residuals and longitudes from a complete set of both ground-based and Voyager stellar and radio occultations of the Uranian rings spanning 1977–2002. We find variations in the radial position of the η ring that are likely generated by this resonance, and take the form of a 3-lobed structure rotating at an angular rate equal to the mean motion of the moon Cressida. The amplitude of these radial oscillations is 0.667±0.113 km, which is consistent with the expected shape due to the perturbations from Cressida. The magnitude of these variations provides the first measurement of the mass and density of the moon Cressida (m =´()2.5 0.4 1017 kg and r =0.86 0.16 gcm−3) or, indeed, any of Uranus’ small inner moons.
