Kazakhstan Missile Chronology
Kazakhstan Missile Chronology Last update: May 2010 As of May 2010, this chronology is no longer being updated. For current developments, please see the Kazakhstan Missile Overview. This annotated chronology is based on the data sources that follow each entry. Public sources often provide conflicting information on classified military programs. In some cases we are unable to resolve these discrepancies, in others we have deliberately refrained from doing so to highlight the potential influence of false or misleading information as it appeared over time. In many cases, we are unable to independently verify claims. Hence in reviewing this chronology, readers should take into account the credibility of the sources employed here. Inclusion in this chronology does not necessarily indicate that a particular development is of direct or indirect proliferation significance. Some entries provide international or domestic context for technological development and national policymaking. Moreover, some entries may refer to developments with positive consequences for nonproliferation. 2009-1947 March 2009 On 4 March 2009, Kazakhstan signed a contract to purchase S-300 air defense missile systems from Russia. According to Ministry of Defense officials, Kazakhstan plans to purchase 10 batteries of S-300PS by 2011. Kazakhstan's Air Defense Commander Aleksandr Sorokin mentioned, however, that the 10 batteries would still not be enough to shield all the most vital" facilities designated earlier by a presidential decree. The export version of S- 300PS (NATO designation SA-10C Grumble) has a maximum range of 75 km and can hit targets moving at up to 1200 m/s at a minimum altitude of 25 meters. -
Hydrazine, Monomethylhydrazine, Dimethylhydrazine and Binary Mixtures Containing These Compounds
Fluid Phase Behavior from Molecular Simulation: Hydrazine, Monomethylhydrazine, Dimethylhydrazine and Binary Mixtures Containing These Compounds Ekaterina Elts1, Thorsten Windmann1, Daniel Staak2, Jadran Vrabec1 ∗ 1 Lehrstuhl f¨ur Thermodynamik und Energietechnik, Universit¨at Paderborn, Warburger Straße 100, 33098 Paderborn, Germany 2 Lonza AG, Chemical Research and Development, CH-3930 Visp, Switzerland Keywords: Molecular modeling and simulation; vapor-liquid equilibrium; Henry’s law constant; Hy- drazine; Monomethylhydrazine; Dimethylhydrazine; Argon; Nitrogen; Carbon Monoxide; Ammonia; Water Abstract New molecular models for Hydrazine and its two most important methylized derivatives (Monomethyl- hydrazine and Dimethylhydrazine) are proposed to study the fluid phase behavior of these hazardous compounds. A parameterization of the classical molecular interaction models is carried out by using quan- tum chemical calculations and subsequent fitting to experimental vapor pressure and saturated liquid density data. To validate the molecular models, vapor-liquid equilibria for the pure hydrazines and binary hydrazine mixtures with Water and Ammonia are calculated and compared with the available experimen- tal data. In addition, the Henry’s law constant for the physical solubility of Argon, Nitrogen and Carbon Monoxide in liquid Hydrazine, Monomethylhydrazine and Dimethylhydrazine is computed. In general, the simulation results are in very good agreement with the experimental data. ∗ corresponding author, tel.: +49-5251/60-2421, fax: +49-5251/60-3522, email: [email protected] 1 1 Introduction On October 24, 1960, the greatest disaster in the history of rocketry, now also known as Nedelin disaster, occurred [1–3]. At that time, the Soviet newspapers published only a short communique informing that Marshall of Artillery Mitrofan Nedelin has died in an airplane crash. -

THE SOLAR DYNAMICS OBSERVER The Solar Dynamics Observer was launched on February 11, 2010 to study the “weather” in space that is caused by the Sun. After launch it climbed up to a geostationary orbit in which it goes around the earth exactly once per day. You can find an overview of the project at NASA’s Mission Pages. Next Generation Science Standards (NGSS): ● Discipline: Motion and Stability: Earth’s Place in the Universe ● Crosscutting Concept: Patterns ● Science & Engineering Practice: Analyzing and Interpreting Data GRADES K-2 1-ESS1-1. Use observations of the sun, moon, and stars to describe patterns that can be predicted. The sun is something that all of us notice. We comment on whether it is a sunny or cloudy day, whether it is too hot or too bright. And we have all been warned not to stare directly at the sun. Even though humans cannot look directly at it without hurting their eyes, NASA has something that can watch the sun without even blinking. It is the Solar Dynamics Observer, or the SDO. Just as your name tells who you are, so does the SDO’s name. Solar means that it deals with the sun. Dynamics means that it studies changes and motion. Observer means that it watches; formally speaking, it holds science machinery that is used to study things that happen in nature. -

This digital version is published by McIntyre Library, University of Wisconsin Eau Claire with the consent of the author. i Abstract: Looking at the debriefing transcripts from double-agent Col. Oleg Penkovsky reveals a wealth of information. This information proved useful in two Cold War crises: the Berlin Crisis of 1961 and the Cuban Missile Crisis. While technology provides insight into what one’s opponents are doing, it lacks the distinctly human factor necessary for a full assessment of a given situation. Looking at the case of Oleg Penkovsky, we see what might drive one to defect, the importance of human intelligence, and its effects on Cold War crises. ii Table of Contents: Title Page…………………………………………………………………………………………i Abstract…………………………………………………………………………………………..ii Table of Contents………………………………………………………………………………..iii Glossary………………………………………………………………………………………….iv Introduction………………………………………………………………………………………5 “They Deceived Me”: Penkovsky’s Early life and Career…………………………………...11 “I am your soldier now.”: Penkovsky’s Decision to Defect…………………………………..14 The Neighbors & the Nearest Neighbors: The Soviet Union’s Intelligence Agencies……...24 The Two Pills: The Berlin Crisis of 1958-1961………………………………………………..29 “If we give them rockets there will be a war.”: The Cuban Missile Crisis…………………36 Conclusion………………………………………………………………………………………41 Bibliography…………………………………………………………………………………….45 iii Glossary.

A New Concept and Technologies of Creating Cosmic Humanity
Cosmic Union of Communities: a New Concept and Technologies of Creating Cosmic Humanity Sergey Krichevsky1 Doctor of Philosophical Sciences, Professor, Institute of the History of Science and Technology named after S.I. Vavilov RAS (Moscow, Russia) E-mail: [email protected] https://orcid.org/0000-0002-1094-7770 The article deals with the philosophical foundations of the theory and practice of creating Cosmic Humanity. It suggests a new idea, concept and technology of organizing cosmic communities, i.e. communities of people aspiring to space, striving to explore space, to fly and live beyond the Earth: the Cosmic Union of communities for the implementation of the superglobal project to create Cosmic Humanity. The methodological, social and technological aspects of the evolution of cosmic communities are described. The options, ways, models and projects of the institutionalization of such communities in the process of space exploration, as well as the creation of Cosmic Humanity are systematized. A brief analysis of the history and experience gained during the Space Age and the Space Revolution is made using the examples of the two types of Cosmic Humanity: (1) the global astronaut community (1959-2018) and (2) the Asgardian community — a megaproject of the first space state created in the cosmopolitan paradigm form of constitutional monarchy based on digital technology (2016-2018). A new powerful stream of people aspiring into space (more than 1 million people) has arisen and is growing. The problems and features of the transition process during the creation of Cosmic Humanity are shown. A general assessment of the potential and problems of applying new technologies is given.
