Vanguard was also the name given to the artificial satellites, as well as the rockets that launched them. In 11 attempts, only three Vanguard launches were successful. The first attempt, Vanguard TV3, failed on December 6, 1957. After the successful launch of Explorer I, Vanguard 1, launched on March 17, 1958, became the second artificial satellite (and the first solar-powered satellite) successfully placed in Earth orbit by the U.S. The other successful launches The Vanguard satellite was the second U.S. satellite were Vanguard 2, launched on February 17, 1959, and put into orbit.

Objects such as aircraft, parts of aircraft, or models of these, are placed inside the wind tunnel so researchers can investigate the flow of air around them and the aerodynamic forces acting upon them. The 16-foot transonic tunnel is one of 23 major wind tunnels at NASA’s Langley Research Center. World War II (WWII) – a war fought from 1939 to 1945, in which the Allied Forces (Great Britain, France, the USSR, the United States, China, and other countries) defeated the Axis Forces (Germany, Italy, and Japan) 102 Lesson 4 Student Text—The Race Begins The Race Begins What is the National Aeronautics and Space Administration (NASA)? What do you think of when you hear the word NASA? You might think of the Space Shuttle. Or you may think of astronauts landing on the Moon. Then again, you might think about the International Space Station (ISS) orbiting the Earth, where men and women live and work for months in space. Perhaps you have heard the news about NASA’s plans to take humans back to the Moon and someday on to Mars and beyond. NASA is responsible for all of this and a whole lot more. NASA is the United States (U.S.) government agency that is leading us through the space age as it makes discoveries about our universe and directs the U.S. exploration of space. The Courage to Soar Higher—An Educator Guide With Activities In Science, Mathematics, Language Arts, and Technology 103 Lesson 4 Student Text—The Race Begins The name NASA is used so often that most people do not know what the letters stand for. The N stands for ational National. National comes from the word nation and our nation is the United States. The A is forAeronautics which eronautics and means the science of designing, building, and operating aircraft. The S is for Space, meaning the whole universe. pace The last A is for Administration. They are the people who manage all of the work at NASA. dministration So, NASA hires a lot of people to do a lot of work that deals with flight. They help design better aircraft for the sky and spacecraft to take us into space. They build telescopes and robots to explore the universe. Theirsatellites collect data about Earth and their scientists use the data to help make Earth a better place. The technology developed in the space programs has been used in countless ways to enrich our lives and even to save lives.

NASA technology touches our lives everyday. 104 Lesson 4 Student Text—The Race Begins Right now, NASA is preparing to send humans back to the Moon and then on to Mars and beyond. NASA is a world leader in the air and space business and people all over the world admire and respect what NASA does. But how did NASA achieve this respect? Let’s look back.(G NACA, Not NASA We know that the Wright Brothers were Americans who flew the first airplane at Kitty Hawk, North Carolina, in 1903. But Americans did not appreciate the Wrights, nor did they recognize the importance of their invention. At first, America was not even interested in flight and ignored this new machine called an airplane. But it was not that way in Europe. Europeans were working hard to improve airplanes. The U.S. soon realized that they were being left behind in this new and important business of airplane transportation. So Congress passed a bill and created an agency that would take The ational aviation in the U.S.

  • The Space Race
    The Space Race Aims: To arrange the key events of the “Space Race” in chronological order. To decide which country won the Space Race. Space – the Final Frontier “Space” is everything Atmosphere that exists outside of our planet’s atmosphere. The atmosphere is the layer of Earth gas which surrounds our planet. Without it, none of us would be able to breathe! Space The sun is a star which is orbited (circled) by a system of planets. Earth is the third planet from the sun. There are nine planets in our solar system. How many of the other eight can you name? Neptune Saturn Mars Venus SUN Pluto Uranus Jupiter EARTH Mercury What has this got to do with the COLD WAR? Another element of the Cold War was the race to control the final frontier – outer space! Why do you think this would be so important? The Space Race was considered important because it showed the world which country had the best science, technology, and economic system. It would prove which country was the greatest of the superpowers, the USSR or the USA, and which political system was the best – communism or capitalism. https://www.youtube.com/watch?v=xvaEvCNZymo The Space Race – key events Discuss the following slides in your groups. For each slide, try to agree on: • which of the three options is correct • whether this was an achievement of the Soviet Union (USSR) or the Americans (USA). When did humans first send a satellite into orbit around the Earth? 1940s, 1950s or 1960s? Sputnik 1 was launched in October 1957.

  • Chapter Fourteen Men Into Space: the Space Race and Entertainment Television Margaret A. Weitekamp
    CHAPTER FOURTEEN MEN INTO SPACE: THE SPACE RACE AND ENTERTAINMENT TELEVISION MARGARET A. WEITEKAMP The origins of the Cold War space race were not only political and technological, but also cultural.1 On American television, the drama, Men into Space (CBS, 1959-60), illustrated one way that entertainment television shaped the United States’ entry into the Cold War space race in the 1950s. By examining the program’s relationship to previous space operas and spaceflight advocacy, a close reading of the 38 episodes reveals how gender roles, the dangers of spaceflight, and the realities of the Moon as a place were depicted. By doing so, this article seeks to build upon and develop the recent scholarly investigations into cultural aspects of the Cold War. The space age began with the launch of the first artificial satellite, Sputnik, by the Soviet Union on October 4, 1957. But the space race that followed was not a foregone conclusion. When examining the United States, scholars have examined all of the factors that led to the space technology competition that emerged.2 Notably, Howard McCurdy has argued in Space and the American Imagination (1997) that proponents of human spaceflight 1 Notably, Asif A. Siddiqi, The Rocket’s Red Glare: Spaceflight and the Soviet Imagination, 1857-1957, Cambridge Centennial of Flight (Cambridge: Cambridge University Press, 2010) offers the first history of the social and cultural contexts of Soviet science and the military rocket program. Alexander C. T. Geppert, ed., Imagining Outer Space: European Astroculture in the Twentieth Century (New York: Palgrave Macmillan, 2012) resulted from a conference examining the intersections of the social, cultural, and political histories of spaceflight in the Western European context.

    NASA NASA SP-8074 SPACE VEHICLE DESIGN CRITERIA (GUIDANCE AND CONTROL) SPACECRAFT SOLAR CELL ARRAYS MAY 1971 NATIONAL AERONAUTICS AND SPACE ADMINISTRATION c GUIDE TO THE USE OF THIS MONOGRAPH The purpose of this monograph is to organize and present, for effective use in design, the signifi- cant experience and knowledge accumulated in operational programs to date. It reviews and assesses current state-of-the-art design practices, and from them establishes firm guidance for achieving greater consistency in design, increased reliability in the end product, and greater efficiency in the design effort for conventional missions. The monograph is organized into three major sections that are preceded by a brief introduction and complemented by a set of references. The State of the Art, Section 2, reviews and discusses the total design problem, and identifies which1 design elements are involved in successful design. It describes succinctly the current tech- nology pertaining to these elements. When detailed information is required, the best available references are cited. This section serves as a survey of the subject that provides background material and prepares a proper technological base for the Design Criteria and Recommended Practices.
