ATOMIC HERITAGE FOUNDATION Preserving & Interpreting Manhattan Project History & Legacy preserving history ANNUAL REPORT 2013 WHY WE SHOULD PRESERVE THE MANHATTAN PROJECT “The factories and bombs that Manhattan Project scientists, engineers, and workers built were physical objects that depended for their operation on physics, chemistry, metallurgy, and other nat- ural sciences, but their social reality - their meaning, if you will - was human, social, political....We preserve what we value of the physical past because it specifically embodies our social past....When we lose parts of our physical past, we lose parts of our common social past as well.” “The new knowledge of nuclear energy has undoubtedly limited national sovereignty and scaled down the destructiveness of war. If that’s not a good enough reason to work for and contribute to the Manhattan Project’s historic preservation, what would be? It’s certainly good enough for me.” ~Richard Rhodes, “Why We Should Preserve the Manhattan Project,” Bulletin of the Atomic Scientists, May/June 2006 Photographs clockwise from top: J.

Exploration of the Moon
Exploration of the Moon The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it. NASA's Apollo program was the first, and to date only, mission to successfully land humans on the Moon, which it did six times. The first landing took place in 1969, when astronauts placed scientific instruments and returnedlunar samples to Earth.

Contents Early history Space race Recent exploration Plans Past and future lunar missions See also References External links Early history The ancient Greek philosopher Anaxagoras (d. 428 BC) reasoned that the Sun and Moon were both giant spherical rocks, and that the latter reflected the light of the former. His non-religious view of the heavens was one cause for his imprisonment and eventual exile.[1] In his little book On the Face in the Moon's Orb, Plutarch suggested that the Moon had deep recesses in which the light of the Sun did not reach and that the spots are nothing but the shadows of rivers or deep chasms. -

James Boerio i ABSTRACT Plasma processes, including plasma etching and plasma polymerization, were investigated for the pretreatment of aluminum prior to structural adhesive bonding. Since native oxides of aluminum are unstable in the presence of moisture at elevated temperature, surface engineering processes must usually be applied to aluminum prior to adhesive bonding to produce oxides that are stable. Plasma processes are attractive for surface engineering since they take place in the gas phase and do not produce effluents that are difficult to dispose off. Reactive species that are generated in plasmas have relatively short lifetimes and form inert products. -

Spacecraft Deliberately Crashed on the Lunar Surface
A Summary of Human History on the Moon Only One of These Footprints is Protected The narrative of human history on the Moon represents the dawn of our evolution into a spacefaring species. The landing sites - hard, soft and crewed - are the ultimate example of universal human heritage; a true memorial to human ingenuity and accomplishment. They mark humankind’s greatest technological achievements, and they are the first archaeological sites with human activity that are not on Earth. We believe our cultural heritage in outer space, including our first Moonprints, deserves to be protected the same way we protect our first bipedal footsteps in Laetoli, Tanzania. Credit: John Reader/Science Photo Library Luna 2 is the first human-made object to impact our Moon. 2 September 1959: First Human Object Impacts the Moon On 12 September 1959, a rocket launched from Earth carrying a 390 kg spacecraft headed to the Moon. Luna 2 flew through space for more than 30 hours before releasing a bright orange cloud of sodium gas which both allowed scientists to track the spacecraft and provided data on the behavior of gas in space. On 14 September 1959, Luna 2 crash-landed on the Moon, as did part of the rocket that carried the spacecraft there. These were the first items humans placed on an extraterrestrial surface. Ever. Luna 2 carried a sphere, like the one pictured here, covered with medallions stamped with the emblem of the Soviet Union and the year. When Luna 2 impacted the Moon, the sphere was ejected and the medallions were scattered across the lunar Credit: Patrick Pelletier surface where they remain, undisturbed, to this day. -
Viscosity from Newton to Modern Non-Equilibrium Statistical Mechanics
Viscosity from Newton to Modern Non-equilibrium Statistical Mechanics S´ebastien Viscardy Belgian Institute for Space Aeronomy, 3, Avenue Circulaire, B-1180 Brussels, Belgium Abstract In the second half of the 19th century, the kinetic theory of gases has probably raised one of the most impassioned de- bates in the history of science. The so-called reversibility paradox around which intense polemics occurred reveals the apparent incompatibility between the microscopic and macroscopic levels. While classical mechanics describes the motionof bodies such as atoms and moleculesby means of time reversible equations, thermodynamics emphasizes the irreversible character of macroscopic phenomena such as viscosity. Aiming at reconciling both levels of description, Boltzmann proposed a probabilistic explanation. Nevertheless, such an interpretation has not totally convinced gen- erations of physicists, so that this question has constantly animated the scientific community since his seminal work. In this context, an important breakthrough in dynamical systems theory has shown that the hypothesis of microscopic chaos played a key role and provided a dynamical interpretation of the emergence of irreversibility. Using viscosity as a leading concept, we sketch the historical development of the concepts related to this fundamental issue up to recent advances. Following the analysis of the Liouville equation introducing the concept of Pollicott-Ruelle resonances, two successful approaches — the escape-rate formalism and the hydrodynamic-mode method — establish remarkable relationships between transport processes and chaotic properties of the underlying Hamiltonian dynamics.

Asymmetric Terracing of Lunar Highland Craters: Influence of Pre-Impact Topography and Structure
Proc. L~lnorPli~nel. Sci. Corrf. /Of11 (1979), p. 2597-2607 Printed in the United States of America Asymmetric terracing of lunar highland craters: Influence of pre-impact topography and structure Ann W. Gifford and Ted A. Maxwell Center for Earth and Planetary Studies, National Air and Space Museum, Smithsonian Institition, Washington, DC 20560 Abstract-The effects of variable pre-impact topography and substrate on slumping and terrace for- mation have been studied on a group of 30 craters in the lunar highlands. These craters are charac- terized by a distinct upper slump block and are all situated on the rim of a larger, older crater or a degraded rim segment. Wide, isolated terraces occur where the rim of the younger crater coincides with a rim segment of the older crater. The craters are all located in Nectarianlpre-Nectarian highland units, and range in age from Imbrian to Copernican. A proposed model for formation of slump blocks in these craters includes the existence of layers with different competence in an overturned rim of the pre-existing crater. Such layering could have resulted from overturning of more coherent layers during formation of the Nectarian and pre-Nec- tarian craters. A combination of material and topographic effects is therefore responsible for terrace formation. Similar terrain effects may be present on other planets and should be considered when interpreting crater statistics in relation to morphology. INTRODUCTION Slumping, terracing or wall failure is an important process in formation and mod- ification of lunar craters. The process of slumping has been investigated by both geometrical (Cintala et a1 ., 1977) and theoretical models (Melosh, 1977; Melosh and McKinnon, 1979); however, these studies are dependent on morphologic constraints imposed by the geologic setting of the craters. -

Cartography for Lunar Exploration: 2006 Status and Planned Missions
CARTOGRAPHY FOR LUNAR EXPLORATION: 2006 STATUS AND PLANNED MISSIONS R.L. Kirk, B.A. Archinal, L.R. Gaddis, and M.R. Rosiek U.S. Geological Survey, Flagstaff, AZ 86001, USA - [email protected] Commission IV, WG IV/7 KEY WORDS: Photogrammetry, Cartography, Geodesy, Extra-terrestrial, Exploration, Space, Moon, History, Future ABSTRACT: The initial spacecraft exploration of the Moon in the 1960s–70s yielded extensive data, primarily in the form of film and television images, that were used to produce a large number of hardcopy maps by conventional techniques. A second era of exploration, beginning in the early 1990s, has produced digital data including global multispectral imagery and altimetry, from which a new generation of digital map products tied to a rapidly evolving global control network has been made. Efforts are also underway to scan the earlier hardcopy maps for online distribution and to digitize the film images themselves so that modern processing techniques can be used to make high-resolution digital terrain models (DTMs) and image mosaics consistent with the current global control. The pace of lunar exploration is about to accelerate dramatically, with as many of seven new missions planned for the current decade. These missions, of which the most important for cartography are SMART-1 (Europe), SELENE (Japan), Chang'E-1 (China), Chandrayaan-1 (India), and Lunar Reconnaissance Orbiter (USA), will return a volume of data exceeding that of all previous lunar and planetary missions combined. Framing and scanner camera images, including multispectral and stereo data, hyperspectral images, synthetic aperture radar (SAR) images, and laser altimetry will all be collected, including, in most cases, multiple datasets of each type.
