Scientific missions to the Moon and Mars will address questions of profound interest to the human race. These include: the origins and history of the solar system; whether life is unique to Earth; and how life on Earth began. If our close neighbour, Mars, is found to be devoid of life, important lessons may be learned regarding the future of our own planet. 2. While the exploration of the Moon and Mars can and is being addressed by unmanned missions we have concluded that the capabilities of robotic spacecraft will fall well short of those of human explorers for the foreseeable future. -
Launch and Deployment Analysis for a Small, MEO, Technology Demonstration Satellite
46th AIAA Aerospace Sciences Meeting and Exhibit AIAA 2008-1131 7 – 10 January 20006, Reno, Nevada Launch and Deployment Analysis for a Small, MEO, Technology Demonstration Satellite Stephen A. Whitmore* and Tyson K. Smith† Utah State University, Logan, UT, 84322-4130 A trade study investigating the economics, mass budget, and concept of operations for delivery of a small technology-demonstration satellite to a medium-altitude earth orbit is presented. The mission requires payload deployment at a 19,000 km orbit altitude and an inclination of 55o. Because the payload is a technology demonstrator and not part of an operational mission, launch and deployment costs are a paramount consideration. The payload includes classified technologies; consequently a USA licensed launch system is mandated. A preliminary trade analysis is performed where all available options for FAA-licensed US launch systems are considered. The preliminary trade study selects the Orbital Sciences Minotaur V launch vehicle, derived from the decommissioned Peacekeeper missile system, as the most favorable option for payload delivery. To meet mission objectives the Minotaur V configuration is modified, replacing the baseline 5th stage ATK-37FM motor with the significantly smaller ATK Star 27. The proposed design change enables payload delivery to the required orbit without using a 6th stage kick motor. End-to-end mass budgets are calculated, and a concept of operations is presented. Monte-Carlo simulations are used to characterize the expected accuracy of the final orbit. -

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. -
Nasa As an Instrument of U.S. Foreign Policy
CHAPTER 11 Nasa as an Instrument of U.S. Foreign Policy John Krige as space exploration,and NASA’s role in it in particular,had an effect on society, Hand, if so, on what aspects of it? And how do we measure any such impact? These are challenging questions indeed. The stakeholders in the huge American space program are multiple and include scientists; engineers; research, development, and launch facilities; industry; administrators; and many government agencies, not to speak of Congress and the U.S. taxpayer.The impacts of spaceflight vary widely, from adding to the stockpile of knowledge and stimulating innovation and industry, to training, education, and creating jobs and—if we move beyond the civilian sphere— to enhancing national security and intelligence gathering. And then there are the intangible, difficult to quantify cultural effects that range from inspiring a young girl to become an astronaut to building national pride and prestige in what are, after all, spectacular scientific and technological, managerial, and industrial achievements. This paper briefly considers one small, but I think important and often overlooked, corner of this vast panorama: the place of spaceflight in American foreign policy. I do not simply want to insist that naSa’s international programs have had an important impact as instruments of foreign policy.I also want to suggest that today they have a particularly significant political and cultural role to play in projecting a positive image of American power and American democracy abroad. In a world increasingly torn apart by conflicts over values—conflicts which history teaches us can seldom be resolved by force—i believe we overlook the potential of NASA as an instrument for American foreign policy at our peril. -
Sixty Years of Australia in Space
Journal & Proceedings of the Royal Society of New South Wales, vol. 153, part 1, 2020, pp. 46–57. ISSN 0035-9173/20/010046-12 Sixty years of Australia in space Kerrie Dougherty Space Humanities Department, International Space University, Strasbourg, France Email: [email protected] Abstract Australia’s involvement in space activities commenced in 1957, at the beginning of the Space Age, with space tracking and sounding rocket launches at Woomera. By 1960, Australia was considered one of the leading space-active nations and in 1967 became one of the earliest countries to launch its own satellite. Yet by 1980, Australia’s space prominence had dwindled, with the country lacking both a national space agency and a coherent national space policy. Despite attempts in the latter part of the 1980s to develop an Australian space industry, the lack of a coherent and consistent national space policy and an effective co-ordinating body, left Australia constantly “punching below its weight” in global space activities until the Twenty First Century. This paper will briefly examine the often-contradictory history of Australian space activities from 1957 to the announcement of the Australian Space Agency in 2017, providing background and context for the later papers in this issue. Introduction Launchpad: the Woomera or 60,000 years the Indigenous people of Rocket Range FAustralia have looked to the sky, using “If the Woomera Range did not already exist, the stars to determine their location, find the proposal that Australia should engage in their way across the land and mark the a program of civil space research would be passage of the seasons and the best times unrealistic”. -
Martian Crater Morphology
ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter. -

Gemini 4 An Astronaut Steps into the Void Details the first American spacewalk in a leap forward from the Mercury program Follows each detail of Gemini's extended duration flight, NASA's first, relying extensively on archives Continues the Pioneers in Early Spaceflight series which looks one-by-one at the Mercury and Gemini flights The flight of Gemini 4 in June 1965 was conducted barely four years after the first Americans flew in space. It was a bold step by NASA to accomplish the first American spacewalk and to extend the U.S. flight duration record to four days. This would be double the experience gained from the six Mercury missions combined.

Up, Up, and Away by James J
www.astrosociety.org/uitc No. 34 - Spring 1996 © 1996, Astronomical Society of the Pacific, 390 Ashton Avenue, San Francisco, CA 94112. Up, Up, and Away by James J. Secosky, Bloomfield Central School and George Musser, Astronomical Society of the Pacific Want to take a tour of space? Then just flip around the channels on cable TV. Weather Channel forecasts, CNN newscasts, ESPN sportscasts: They all depend on satellites in Earth orbit. Or call your friends on Mauritius, Madagascar, or Maui: A satellite will relay your voice. Worried about the ozone hole over Antarctica or mass graves in Bosnia? Orbital outposts are keeping watch. The challenge these days is finding something that doesn't involve satellites in one way or other. And satellites are just one perk of the Space Age. Farther afield, robotic space probes have examined all the planets except Pluto, leading to a revolution in the Earth sciences -- from studies of plate tectonics to models of global warming -- now that scientists can compare our world to its planetary siblings. Over 300 people from 26 countries have gone into space, including the 24 astronauts who went on or near the Moon. Who knows how many will go in the next hundred years? In short, space travel has become a part of our lives. But what goes on behind the scenes? It turns out that satellites and spaceships depend on some of the most basic concepts of physics. So space travel isn't just fun to think about; it is a firm grounding in many of the principles that govern our world and our universe.
