Breakthrough Propulsion Study Assessing Interstellar Flight Challenges and Prospects
Breakthrough Propulsion Study Assessing Interstellar Flight Challenges and Prospects NASA Grant No. NNX17AE81G First Year Report Prepared by: Marc G. Millis, Jeff Greason, Rhonda Stevenson Tau Zero Foundation Business Office: 1053 East Third Avenue Broomfield, CO 80020 Prepared for: NASA Headquarters, Space Technology Mission Directorate (STMD) and NASA Innovative Advanced Concepts (NIAC) Washington, DC 20546 June 2018 Millis 2018 Grant NNX17AE81G_for_CR.docx pg 1 of 69 ABSTRACT Progress toward developing an evaluation process for interstellar propulsion and power options is described. The goal is to contrast the challenges, mission choices, and emerging prospects for propulsion and power, to identify which prospects might be more advantageous and under what circumstances, and to identify which technology details might have greater impacts. Unlike prior studies, the infrastructure expenses and prospects for breakthrough advances are included. This first year's focus is on determining the key questions to enable the analysis. Accordingly, a work breakdown structure to organize the information and associated list of variables is offered. A flow diagram of the basic analysis is presented, as well as more detailed methods to convert the performance measures of disparate propulsion methods into common measures of energy, mass, time, and power. Other methods for equitable comparisons include evaluating the prospects under the same assumptions of payload, mission trajectory, and available energy. Missions are divided into three eras of readiness (precursors, era of infrastructure, and era of breakthroughs) as a first step before proceeding to include comparisons of technology advancement rates. Final evaluation "figures of merit" are offered. Preliminary lists of mission architectures and propulsion prospects are provided. -
The Role and Training of NASA Astronauts in the Post-Shuttle Era
The Role and Training of NASA Astronauts in the Post-Shuttle Era Aeronautics and Space Engineering Board ∙ Air Force Studies Board ∙ Division on Engineering & Physical Sciences ∙ September 2011 As the National Aeronautics and Space Administration (NASA) retires the Space Shuttle and shifts involvement in International Space Station (ISS) operations, changes in the role and requirements of NASA’s Astronaut Corps will take place. At the request of NASA, the National Research Council (NRC) addressed three main questions about these changes: What should be the role and size of Johnson Space Center’s (JSC) Flight Crew Operations Directorate (FCOD); what will be the requirements of astronaut training facilities; and is the Astronaut Corps’ fleet of training aircraft a cost-effective means of preparing astronauts for NASA’s spaceflight program? This report presents an assessment of several issues driven by these questions. This report does not address explicitly the future of human spaceflight.

The Role and Training of NASA Astronauts In
Co-chairs: Joe Rothenberg, Fred Gregory Briefing: October 18-19, 2011 Statement of Task An ad hoc committee will conduct a study and prepare a report on the activities of NASA’s human spaceflight crew office. In writing its report the committee will address the following questions: • How should the role and size of the activities managed by the Johnson Space Center Flight Crew Operations Directorate change after space shuttle retirement and completion of the assembly of the International Space Station (ISS)? • What are the requirements of crew-related ground-based facilities after the space shuttle program ends? • Is the fleet of aircraft used for the training the Astronaut Corps a cost-effective means of preparing astronauts to meet the requirements of NASA’s human spaceflight program? Are there more cost-effective means of meeting these training requirements? The NRC was not asked to consider whether or not the United States should continue human spaceflight, or whether there were better alternatives to achieving the nation’s goals without launching humans into space. Rather, the NRC’s charge was to assume that U.S. human spaceflight would continue. 2 Committee on Human Spaceflight Crew Operations • FREDERICK GREGORY, Lohfeld Consulting Group, Inc., Co-Chair • JOSEPH H.

Solar System Exploration: a Vision for the Next Hundred Years
IAC-04-IAA.3.8.1.02 SOLAR SYSTEM EXPLORATION: A VISION FOR THE NEXT HUNDRED YEARS R. L. McNutt, Jr. Johns Hopkins University Applied Physics Laboratory Laurel, Maryland, USA [email protected] ABSTRACT The current challenge of space travel is multi-tiered. It includes continuing the robotic assay of the solar system while pressing the human frontier beyond cislunar space, with Mars as an ob- vious destination. The primary challenge is propulsion. For human voyages beyond Mars (and perhaps to Mars), the refinement of nuclear fission as a power source and propulsive means will likely set the limits to optimal deep space propulsion for the foreseeable future. Costs, driven largely by access to space, continue to stall significant advances for both manned and unmanned missions. While there continues to be a hope that commercialization will lead to lower launch costs, the needed technology, initial capital investments, and markets have con- tinued to fail to materialize. Hence, initial development in deep space will likely remain govern- ment sponsored and driven by scientific goals linked to national prestige and perceived security issues. Against this backdrop, we consider linkage of scientific goals, current efforts, expecta- tions, current technical capabilities, and requirements for the detailed exploration of the solar system and consolidation of off-Earth outposts. Over the next century, distances of 50 AU could be reached by human crews but only if resources are brought to bear by international consortia. INTRODUCTION years hence, if that much3, usually – and rightly – that policy goals and technologies "Where there is no vision the people perish.” will change so radically on longer time scales – Proverbs, 29:181 that further extrapolation must be relegated to the realm of science fiction – or fantasy. -

The Challenge of Interstellar Travel the Challenge of Interstellar Travel
The challenge of interstellar travel The challenge of interstellar travel ! Interstellar travel - travel between star systems - presents one overarching challenge: ! The distances between stars are enormous compared with the distances which our current spacecraft have travelled ! Voyager I is the most distant spacecraft, and is just over 100 AU from the Earth ! The closest star system (Alpha Centauri) is 270,000 AU away! ! Also, the speed of light imposes a strict upper limit to how fast a spacecraft can travel (300,000 km/s) ! in reality, only light can travel this fast How long does it take to travel to Alpha Centauri? Propulsion Ion drive Chemical rockets Chemical Nuclear drive Solar sail F = ma ! Newton’s third law. ! Force = mass x acceleration. ! You bring the mass, your engine provides the force, acceleration is the result The constant acceleration case - plus its problems ! Let’s take the case of Alpha Centauri. ! You are provided with an ion thruster. ! You are told that it provides a constant 1g of acceleration. ! Therefore, you keep accelerating until you reach the half way point before reversing the engine and decelerating the rest of the way - coming to a stop at Alpha Cen. ! Sounds easy? Relativity and nature’s speed limit ! What does it take to maintain 1g of accelaration? ! At low velocities compared to light to accelerate a 1000kg spacecraft at 1g (10ms-2) requires 10,000 N of force. ! However, as the velocity of the spacecraft approaches the velocity of light relativity starts to kick in. ! The relativistic mass can be written as γ x mass, where γ is the relativistic Lorentz factor. -

Welcome Letter Hello delegates and welcome to VAMUN XXXIX and the seventh iteration of the Wilson Global Systems Simulation! My name is Noah Strike and I’ll be your Under-Secretary-General for WGSS this year. For those unfamiliar, WGSS is a groundbreaking four-way geopolitical crisis simulation. Each committee is tasked with not only considering its position in world affairs, but also the positions of its competitors - the other committees. Decisions made in one committee with have ripple effects throughout the simulation, just as in reality. In the past, WGSS topics have included the Congo Crisis of 1964, the Yemeni Civil War, and a less-than historically accurate reenactment of World War I. This year, WGSS is looking to the stars. The years following 2019 have not been friendly to the world. An escalating US-China trade war has decimated trans-Pacific trade and the industrialized economies of both countries; production is down, prices for goods have skyrocketed, and unemployment is at the highest point since the 2008 financial crisis. Political upheaval and shocking regime change in Russia has challenged the world order of the 2010s; political participation and activism are up, but alongside them, socio-economic and political uncertainty threaten Russia’s future. A European Union fractured by a “no-deal” Brexit and subsequent economic collapse between the mainland and the United Kingdom has caused massive turmoil on the continent; trade is down, unemployment is up, and the future unity of the Union is far, far from certain. These crises are, however, dwarfed by the early arrival of the climate catastrophe. -

A spaceport will unlock economic growth and jobs in existing UK industries and regions, while positioning the UK to take advantage of emerging demand for commercial human spaceflight, small satellite launch, microgravity research, parabolic flights, near-space balloon tourism, and eventually high-speed point-to-point travel. Without a specific site selected and looking at the economic impact of a spaceport generically, this report expects the spaceport to deliver approximately £2.5bn and 8,000 jobs to the broader UK economy over 10 years. EXECUTIVE SUMMARY 1 Executive Summary Our plan is for Britain to have a fully functional, operating spaceport “by 2018. This would serve as a European focal point for the pioneers of commercial spaceflight using the potential of spaceflight experience companies like Virgin Galactic, XCOR and Swiss S3 to pave the way for satellite launch services to follow. -

Because it had been nearly twenty-five years since the end of Apollo they pointed out that many of the persons involved in that training might not be around when advice might be sought for future missions of this type. -
