Download Workshop Proceedings Here Proceedings of the Foundations for Interstellar Studies Workshop New York City, 13 – 15 June 2017 Edited by Kelvin F. Long Organised by the Institute for Interstellar Studies (USA) and City Tech City University New York Copyright Statement © 2017 The papers shown in this document remain the copyright property of the individual authors and nobody may use them in other published material without those authors permission. 2 Preface This document contains the written proceedings for the Foundations of Interstellar Studies workshop that took place in New York 13-15 June 2015. This was a scientific technical meeting organised between the Institute for Interstellar Studies (a US based not-for-profit) and City University New York. The event was also sponsored by Stellar Engines Ltd and the Breakthrough Initiatives. Post-workshop, a total of eighteen papers were written up and submitted to the Journal of the British Interplanetary Society. This includes in volume 71 of the journal, published during 2018 as special interstellar studies red covers which included: First Step on the Interstellar Journey: The Solar Gravity Lens Focus, L. Friedman et al. Experimental Simulation of Dust Impacts at Starflight Velocities, A. J. Higgins. Plasma Dynamics in Firefly’s Z-Pinch Fusion Engine, R. M. Freeland. Gram-Scale Nano-Spacecraft Entry into Star Systems, A. A. Jackson. The Interstellar Fusion Fuel Resource Base of Our Solar System, R. G. Kennedy. Tests of Fundamental Physics in Interstellar Flight, R. Kezerashvili. Effects of Enhanced Graphene Reflection on the Performance of Sun-Launched Interstellar Arks, G. L. Matloff. Heat Transfer in Fusion Starship, Radiation Shielding Systems, Michel Lamontagne. Solar System Escape Mission with Solar Sail Spacecraft within a Framework of Post-Newtonian Gravitational Theory, Olga L Starinova and Irina V Gorbunova1. The organisers of the Foundations of Interstellar Studies workshop waited for some time so that the papers could be published in the journal first, but due to the long duration of submission to publish time, we decided to move ahead and show the papers in their original form as submitted to the journal in these official proceedings. This document therefore represents a scientific record of this meeting. In these proceedings, we have attempted to style all of the papers for similar consistency where possible, whilst not taking away from the format intentions of the authors. In addition, not all of the presenting authors at the workshop decided to submit a paper post-meeting, so we have included just their abstract. Finally, some of the presenters were last minute inclusions in the workshop, and for those we did not even have an abstract, although they do have a presence in these proceedings. The proceedings represent the papers presented over the three days of the meeting in three sessions. This included on the themes of (1) Energetic Reactions Engines (2) Sails and Beams (3) Breakthrough Propulsion. These are quite broad areas. During later workshop meetings, we would hope to narrow some of these subjects to more specific questions so as to facilitate more progress. We hope that the papers in these proceedings serve to education, inspire and move the field of interstellar studies forward so that as the progress in science matures, so too will the possibility of achieving the ultimate vision; sending spacecraft to other star systems. 1st March 2019 1 This paper was selected and scheduled for the June 2017 meeting, however the authors were not able to attend and the paper was never presented. However, the authors later submitted the paper to JBIS anyway and it was later published (volume 71, issue 12, December 2018). Although it does not appear in these proceedings of the meeting, it is mentioned here. 3 Contents Page Participating Institutions 6 Welcome from the Chairman at Event 7 Introduction 8 Session 1: Energetic Reaction Engines 9 1.

This event has been a joint collaboration between City Tech and the Institute for Interstellar Studies. Over the next few days you will hear many interesting physics and engineering talks which are relevant to the challenges of interstellar travel. Our goal, is to facilitate interactions through informal conversations and bring people together to discuss current problems in the hope that some solutions can be realized, or future research directions planned. The nearest star system is the Centauri A/B and Proxima Centauri system. Alpha Centauri A, also known as Rigil Kentaurus, is the primary member of the binary system that is around ten percent larger and more luminous than the Sun. Alpha Centauri B is its companion star, smaller and less luminous than the Sun with a mass ten percent less than the Sun. Proxima Centauri, is a small main sequence star, with a mass of around an eighth the mass of the Sun. These make up our closes star system that in the future we may be able to visit using technologies not yet invented. Since 1988 we have discovered over 3,000 exoplanets in over 2,700 planetary systems. This has been mainly due to the success of programs like the Kepler Space Telescope using techniques such as the radial velocity and transit methods. Now that we know there are many star systems we could visit, this opens up the possibility of life existing there too. The only way to find out, is to build robotic spacecraft and send them there to conduct in-situ reconnaissance. Then, sometime later, human exploration and colony ships will likely follow. In the pursuit of this we will surely make many discoveries, but also ensure the survival of our species as we diffuse through the galaxy.

  • 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.

  • Download the Search for New Planets
    “VITAL ARTICLES ON SCIENCE/CREATION” September 1999 Impact #315 THE SEARCH FOR NEW PLANETS by Don DeYoung, Ph.D.* The nine solar system planets, from Mercury to Pluto, have been much-studied targets of the space age. In general, a planet is any massive object which orbits a star, in our case, the Sun. Some have questioned the status of Pluto, mainly because of its small size, but it remains a full-fledged planet. There is little evidence for additional solar planets beyond Pluto. Instead, attention has turned to extrasolar planets which may circle other stars. Intense competition has arisen among astronomers to detect such objects. Success insures media attention, journal publication, and continued research funding. The Interest in Planets Just one word explains the intense interest in new planets—life. Many scientists are convinced that we are not alone in space. Since life evolved on Earth, it must likewise have happened elsewhere, either on planets or their moons. The naïve assumption is that life will arise if we “just add water”: Earth-like planet + water → spontaneous life This equation is falsified by over a century of biological research showing the deep complexity of life. Scarcely is there a fact more certain than that matter does not spring into life on its own. Drake Equation Astronomer Frank Drake pioneered the Search for ExtraTerrestrial Intelligence project, or SETI, in the 1960s. He also attempted to calculate the total number of planets with life. The Drake Equation in simplified form is: Total livable Probability of Planets with planets x evolution = evolved life *Don DeYoung, Ph.D., is an Adjunct Professor of Physics at ICR.

  • Interstellar Travel and the Fermi Paradox
    Interstellar Travel If aliens haven’t visited us, could we go to them? In this lecture we will have some fun speculating about future interstellar travel by humans. Please keep in mind that, as we discussed earlier, this cannot be considered a solution for the problems that we have on Earth, for the simple reason that the expense per person is utterly prohibitive and will remain so in any conceivable future scenario. Nonetheless, given enough time it could be that we have the capacity to move out into the galaxy. Incidentally, we will leave discussions of really far-out concepts such as wormholes to a future class. Interstellar distances The major barrier to interstellar travel is the staggering distance between stars. The closest one to the Sun is Proxima Centauri, which is 4.3 light years away but not a likely host to planets. There are, however, a few possibilities within roughly 10 light years, so that is a good target. How far is 10 light years? By definition it is how far light travels in 10 years, but let’s put this into a more familiar context. A moderately brisk walking pace is 5 km/hr, and since one light year is about 10 trillion kilometers, you would need about 20 trillion hours, or about 2.3 billion years, to walk that distance. The fastest cars sold commercially go about 400 km/hr, so you would need about three billion hours or a bit less than thirty million years. The speed of the Earth in its orbit, which is comparable to the speed of the fastest spacecraft we have constructed (all unmanned, of course), is about 30 km/s and even at that rate it would take about a hundred thousand years to travel ten light years.

  • Solar Electric Propulsion Sail
    IOSR Journal of Electronics and Communication Engineering (IOSR-JECE) e-ISSN: 2278-2834,p- ISSN: 2278-8735.Volume 13, Issue 5, Ver. I (Sep.-Oct. 2018), PP 18-22 www.iosrjournals.org Solar Electric Propulsion Sail Dr. S.S. Subashka Ramesh [1] Sri Haripriya Nutulapti [2], Yashraj Sharma [3], Pratyush Kumar [4] [1], [2], [3], [4] Department of Computer Science and Engineering, SRM institute of science & technology Ramapuram Campus, Chennai-89, India. Corresponding Author: Dr. S.S. Subashka Ramesh Abstract: The solar expedition missions have been minimized mainly due to the performance of the space capsules, also because of the planned amount of fuel a space shuttle must carry without discharging in order to advance to an unfamiliar region. Traditionally, a solar electric propulsion sail is extremely deformable to drive a space rocket through outer space. Photon or electric sails are propounding medium of propulsion by utilizing the cosmic radiation endeavored because of sun’s rays on massive mirrors. It is a fusion of photo-voltaic cells and ions for the propelling and is also capable of enabling very fine maneuvering of the spacecraft by means of large sail-surface deformations. Solar electric propulsion sailutilizes the natural beams of sunlight to advancethe vehicles into and out of space, just the way wind helps to propel the sailboats over the water. NASA team claimed working on the start ofgrowth of technology on the assignment recognized as the solar sail demonstrator which proved thatmaking use of giant, weightless and unfurling objects float in universe would enhance the abilities of travelling deeper in space.
