Introduction INTRODUCTION This publication consists of 11 selected papers from workshops organized by the United Nations Office for Outer Space Affairs, within the framework of the Programme on Space Applications in 2004. The Programme on Space Applications was established in 1971, with one of its main objectives to further general knowledge and experiences in the field of space technology between developed and developing countries. The Programme organizes around ten workshops, seminars and training courses on an annual basis for students and professionals from developing countries with the aim of increasing local capabilities in space technologies, thus helping to promote the peaceful use of outer space, in accordance with United Nations goals and principles. These activities bring together professionals from developed and developing countries and allow for an exchange of information in several space-related fields, including telecommunications, remote sensing and satellite applications, global environment and land resources management and international space regulations. This volume of “Seminars of the United Nations Programme on Space Applications” is the sixteenth publication in an annual series that began in 1989. The selected papers discuss a variety of science policy issues and are published in the language of submission. -iii- CONTENTS Introduction ............................................................................................................iii I.

APPLICATION-BASED THEMES Space-based Data: Between Pure Science and Down-to-Earth Application in Indonesia Thomas Djamaluddin National Institute of Aeronautics and Space (LAPAN) Bandung, Indonesia [email protected], [email protected] Abstract An unclear night or an unclear day are obstacles for ground-based solar observation. With that in mind, space-based data are very important to overcome such obstacles. Originally, the first work on space-based data was done by using Infra Red Astronomical Satellite (IRAS) data in analyzing young stellar objects (YSOs). In that connection, unbiased and almost all-sky coverage data are considerably important in studying the evolution of young stellar objects. Such pure science research can be conducted by using the online or CD-ordered data. In addition, for a developing country such as Indonesia, space science observation faces other problems such as lack of sophisticated observational facilities. Moreover, for any research budget proposal (except for university research projects), the application of the results directly or indirectly should also be included at a certain point in time. Besides having affordable facilities, such as small telescopes and data processing computers, space- based data are accessible through the Internet and considerably rich to be used in research for several applications. In addition to ground-based observation, solar physical, solar-terrestrial and physical space-based data are mainly used in the so- called "down-to-earth" research application on space sciences. This paper discusses the utilization of space-based data for space science researches in Indonesia and its related problems. Firstly, space-based data and the problems in accessing it are briefly reviewed. Secondly, an example of utilizing space data for scientific research only is also discussed. Lastly, an example of "down-to- earth" research application is provided. 1. Introduction Space researchers have been collecting and analyzing information received mainly by electromagnetic detectors. Unfortunately, not all ranges of electromagnetic radiation from space objects are able to reach ground-based observational instruments. Visible and radio waves are the two ranges of electromagnetic spectra that can be detected from the ground. However, clouds prevent good and effective results from observing outer space. Astronomical as well as solar physical observation need clear seeing. Following recent progress made in the field of space technology, many orbiting observatories have been launched into outer space. Modern developments have become extremely important to overcome the limited number of days and nights normally used for space observation. Furthermore, space-based observatories can provide all ranges of electromagnetic spectra. -3- 2. Space-based data In general, space-based data can be divided into three groups: astrophysical, solar-physical and solar-terrestrial physical data. In order to mention some space- based data, a brief review will be provided.1 Radio–microwave–infrared observations have been performed by several space missions: Ariel 2, 3, and 4, Radio Astronomy Explorer (RAE) 1 (Explorer 38) and 2 (Explorer 49) (Nasa) Explorer 38 (RAE-1), Explorer 49 (RAE-2), The Very Long Baseline Interferometry (VLBI) Space Observatory Program (VSOP), RADIOASTRON, Cosmic Background Explorer (COBE), Submillimeter Wave Astronomy Satellite (SWAS), and Microwave Anisotropy Probe (MAP). MAP was launched into an orbit around the L2 Lagrange point of the Sun-Earth system. The Infra Red Astronomical Satellite (IRAS) has also conducted sky surveys. In addition, there is the Infrared Space Observatory (ISO). Other examples of infrared space observatories include the Spitzer Space Telescope (SST)/Space Infrared Telescope Facility (SIRTF), the Infrared Telescope Satellite/Space Flyer Unit IRTS/SFU, and the Midcourse Space Experiment (MSX). In the visible spectrum there are the Hipparcos and the Hubble Space Telescope (HST). Hipparcos was the astrometrical satellite for measuring high precision parallaxes, while the HST is an excellent imaging facility. HST can also perform a great deal of observations at ultraviolet wavelengths. In addition, the International Ultraviolet Explorer (IUE) operates and observes ultraviolet radiation. Other examples of UV observatories are: Astron-1, Far UV Spectroscopic Explorer (FUSE) and Galaxy Evolution Explorer (GALEX). High-energy observations in EUV, X-ray, and Gamma-ray have been condicted by several space missions, such as the Astronomical Netherlands Satellite (ANS), the Extreme Ultraviolet Explorer (EUVE), and the Array of Low Energy X- ray Imaging Sensors (ALEXIS). Other examples include the Rossi X-ray Timing Explorer (RXTE), the Advanced Satellite for Cosmology and Astrophysics (ASCA), Chandra X-ray Observatory (CXO), Uhuru, The Compton Gamma-Ray Observatory (CGRO), and many others. Regarding solar physics research, several satellites have been sent into orbit. Ulysses, Yohkoh, the Transition Region and Coronal Explorer (TRACE), and the Solar and Heliospheric Observatory (SOHO) are examples of several satellites that observe the Sun continuously. Furthermore, the Geostationary Operational Environmental Satellite (GOES) produces data which are very important in studying solar-terrestrial physics. In general, images and numerical data (including graphical plots data) are produced to be further analyzed. Several space-based data are now open to the public and can be accessed online via the Internet or distributed through CD-ROMs or other media. This is important since data access via the Internet is very useful to the scientific community. However, there is a problem of data access via the Internet depending on the bandwidth of the Internet connection, which is in turn related to 1 (extracted from http://imagine.gsfc.nasa.gov/index.html,http://www.seds.org/~spider/oaos/oaos.html) -4- problems regarding research budget. The expensive, high speed Internet and the difficulties in downloading images from it, along with the lack of analyzing tools (e.g. expensive Interactive Data Language – IDL) are all elements that prevent scientists

  • Mr. Jeffrey Manber Testimony.Pdf
    Testimony of Mr. Jeffrey Manber Chief Executive Officer, Nanoracks LLC before the Senate Committee on Commerce, Science and Transportation Subcommittee on Aviation and Space Tuesday, November 5, 2019 Building NASA’s Workforce of the Future: STEM Engagement for a 21st Century Education Chairman Cruz, Ranking Member Sinema, and other distinguished members of the Aviation and Space Subcommittee, thank you for giving me the opportunity to return to this room to testify before you. I look forward to discussing how commercial access to the International Space Station has provided an unprecedented educational experience to over a million students across the United States. Let me begin today by explaining that I am here in two different capacities. I am, of course, representing Nanoracks as the CEO, but I am also Chairman of the Board for DreamUp, Nanoracks’ educational sister company. Once just a division in Nanoracks, we spun DreamUp out to be a standalone public benefit corporation because the business of providing educational access to space was, and remains today, strong and important. DreamUp’s sole focus is bringing space to the classroom, and the classroom to space. We opened the doors at Nanoracks in 2009 with the goal to make space accessible to everyone. I am proud to say today that the very first customers that brought Nanoracks into business were in fact, schools. Our very first experiments were small projects that were developed by middle school students. These kids quite literally held bake sales - not to sponsor their soccer team, or raise money for the school dance, but to send their very own science experiment to the International Space Station via a Nanoracks Space Act Agreement with NASA.

  • The Emergence of Space Law
    THE EMERGENCE OF SPACE LAW Steve Doyle* I. INTRODUCTION Space law exists today as a widely regarded, separate field of jurisprudence; however, it has many overlapping features involving other fields, including international law, contract law, tort law, and administrative law, among others.1 Development of space law concepts began early in the twentieth century and blossomed during the second half of the century into its present state. It is not yet widely taught in law schools, but space law is gradually being accorded more space in law school curricula. Substantial notional law and concepts of space law emerged prior to the first orbiting of a man made satellite named Sputnik in 1957. During the next decade (1958-1967), an intense effort was made to bring law into compliance with the realities of expanding spaceflight activities. During the 1960s, numerous national and international regulatory laws emerged to deal with satellite launches and space radio uses and to ensure greater international awareness and governmental presence in the oversight of ongoing activities in space. Just as gradually developed bodies of maritime law emerged to regulate the operation of global shipping, aeronautical law emerged to regulate the expansion of global civil aviation, and telecommunication law emerged to regulate the global uses of radio and wire communication systems, a new body of law is emerging to regulate the activities of nations in astronautics. We know that new body of law as Space Law. * Stephen E. Doyle is Honorary Director, International Institute of Space Law, Paris. Mr. Doyle worked fifteen years in federal civil service (1966-1981), fifteen years in the aerospace industry (1981-1996), and fifteen years in the power production industry (1996-2012).

Robinson 1,3 * 1 Institute for Innovation and Public Purpose, University College London, UK 2 Science Policy Research Unit (SPRU), University of Sussex, UK 3 Laboratoire Interdisciplinaire Sciences Innovations Sociétés (LISIS), CNRS-INRA-ESIEE- UPEM, Université Paris-Est Marne-la-Vallée, France * Corresponding author : [email protected] Abstract A recent report from NASA’s office of the chief technologist positions a self-sustained “low-earth-orbit ecosystem” as a desirable objective for NASA’s human spaceflight policy and linking to its larger aims of deeper exploration of the solar system. The report follows a wave of mission shifts and space policy directives which emphasize that the private sector should be given more power and receive public agency financial support to stimulate space services. To understand how US space innovation activities are changing, and to be able to make assessments and policy recommendations, we use an innovation ecosystems approach to help understand the types of relationships between actors in low-earth-orbit and to determine the ramifications for US space policy. Our findings reveal four new forms of relationships between NASAA and other parties in the emerging innovation ecosystem and we discuss how these lead to policy challenges for NASA as a mission-oriented public agency with the new additional objective of creating an economic zone in orbit. 1. Introduction Historically, NASA’s mission-oriented programs for innovation have been driven by security concerns and by the need for maintaining technical leadership over other nations.

  • ESA Strategy for Science at the Moon
    ESA UNCLASSIFIED - Releasable to the Public ESA Strategy for Science at the Moon ESA UNCLASSIFIED - Releasable to the Public EXECUTIVE SUMMARY A new era of space exploration is beginning, with multiple international and private sector actors engaged and with the Moon as its cornerstone. This renaissance in lunar exploration will offer new opportunities for science across a multitude of disciplines from planetary geology to astronomy and astrobiology whilst preparing the knowledge humanity will need to explore further into the Solar System. Recent missions and new analyses of samples retrieved during Apollo have transformed our understanding of the Moon and the science that can be performed there. We now understand the scientific importance of further exploration of the Moon to understand the origins and evolution of Earth and the cosmic context of life’s emergence on Earth and our future in space. ESA’s priorities for scientific activities at the Moon in the next ten years are: • Analysis of new and diverse samples from the Moon. • Detection and characterisation of polar water ice and other lunar volatiles. • Deployment of geophysical instruments and the build up a global geophysical network. • Identification and characterisation of potential resources for future exploration. • Deployment long wavelength radio astronomy receivers on the lunar far side. • Characterisation of the dynamic dust, charge and plasma environment. • Characterisation of biological sensitivity to the lunar environment.
