Issues With The Data Many of these projects don’t have documented cost and schedule data Even if total cost exists, it is not at the subsystem level Some of the projects are commercial or even non-U.S. 10 Many of These Projects Don’t Have Documented Data • Don’t underestimate the power of… ° Industrial espionage ° Really determined data scroungers • The total cost, schedule and mass of many of these missions is given on various websites, in space news articles, etc. ° Sometimes wet mass, but dry mass can be estimated easily from wet mass ° Total cost and schedule can be sanity checked by comparing with some known analogies 11 Cost And Mass Does Not Exits At The Subsystem Level • We visualize the HMCM to initially operate at the subsystem level ° With mass as the principal independent variable at first ° Other variables can be added later to address numerous other cost drivers ° Let’s just get the basic first step done • We are proposing that “missing” subsystem data can be imputed ° The Galorath Chief Engineer, Dr. Christian Smart, is speaking at this symposium on imputation ° A simple way to think about how missing data could be estimated ° Tabulate subsystem cost and mass breakouts of all the known data points ° Select which historical projects with complete data are analogous to the projects with data holes ° Apply those percentages to the projects lacking subsystem data ° Balance the books so that all elements add to the total 12 Some Of The Projects Are Commercial or Even Non-U.S • The physics and engineering are the same • Institutional culture may be different ° NASA, ESA, ASI, JAXA cost scatterplot on top of each other ° ESA member countries “eat overruns” ° However, there are inefficiencies of assigning work to member nations ° These two things seem to about cancel out ° Commercial projects in comparison to NASA has been analyzed ° Somewhere in the 50% range give or take ° Therefore, upward adjustments can be made for commercial cost data to get everything on a level playing field ° Again, other variables can be added/re-introduced later ° NASA and Roscosmos differences will be more problematic ° But not an overwhelming problem 13 °

    Russia’s Posture in Space: Prospects for Europe Executive Summary Prepared by the European Space Policy Institute Marco ALIBERTI Ksenia LISITSYNA May 2018 Table of Contents Background and Research Objectives ........................................................................................ 1 Domestic Developments in Russia’s Space Programme ............................................................ 2 Russia’s International Space Posture ......................................................................................... 4 Prospects for Europe .................................................................................................................. 5 Background and Research Objectives For the 50th anniversary of the launch of Sputnik-1, in 2007, the rebirth of Russian space activities appeared well on its way. After the decade-long crisis of the 1990s, the country’s political leadership guided by President Putin gave new impetus to the development of national space activities and put the sector back among the top priorities of Moscow’s domestic and foreign policy agenda. Supported by the progressive recovery of Russia’s economy, renewed political stability, and an improving external environment, Russia re-asserted strong ambitions and the resolve to regain its original position on the international scene. Towards this, several major space programmes were adopted, including the Federal Space Programme 2006-2015, the Federal Target Programme on the development of Russian cosmodromes, and the Federal Target Programme on the redeployment of GLONASS. This renewed commitment to the development of space activities was duly reflected in a sharp increase in the country’s launch rate and space budget throughout the decade. Thanks to the funds made available by flourishing energy exports, Russia’s space expenditure continued to grow even in the midst of the global financial crisis. Besides new programmes and increased funding, the spectrum of activities was also widened to encompass a new focus on space applications and commercial products.

  • Jules Verne ATV Launch Approaching 11 February 2008
    Jules Verne ATV launch approaching 11 February 2008 will carry up to 9 tonnes of cargo to the station as it orbits 400 km above the Earth. Equipped with its own propulsion and navigation systems, the ATV is a multi-functional spacecraft, combining the fully automatic capabilities of an unmanned vehicle with the safety requirements of a crewed vehicle . Its mission in space will resemble that, on the ground, of a truck (the ATV) delivering goods and services to a research establishment (the space station). A new-generation high-precision navigation system will guide the ATV on a rendezvous trajectory towards the station. In early April, Jules Verne will automatically dock with the station’s Russian Preview of the maiden launch and docking of ESA's Jules Verne ATV.

  • Pete Aldridge Well, Good Afternoon, Ladies and Gentlemen, and Welcome to the Fifth and Final Public Hearing of the President’S Commission on Moon, Mars, and Beyond
    The President’s Commission on Implementation of United States Space Exploration Policy PUBLIC HEARING Asia Society 725 Park Avenue New York, NY Monday, May 3, and Tuesday, May 4, 2004 Pete Aldridge Well, good afternoon, ladies and gentlemen, and welcome to the fifth and final public hearing of the President’s Commission on Moon, Mars, and Beyond. I think I can speak for everyone here when I say that the time period since this Commission was appointed and asked to produce a report has elapsed at the speed of light. At least it seems that way. Since February, we’ve heard testimonies from a broad range of space experts, the Mars rovers have won an expanded audience of space enthusiasts, and a renewed interest in space science has surfaced, calling for a new generation of space educators. In less than a month, we will present our findings to the White House. The Commission is here to explore ways to achieve the President’s vision of going back to the Moon and on to Mars and beyond. We have listened and talked to experts at four previous hearings—in Washington, D.C.; Dayton, Ohio; Atlanta, Georgia; and San Francisco, California—and talked among ourselves and we realize that this vision produces a focus not just for NASA but a focus that can revitalize US space capability and have a significant impact on our nation’s industrial base, and academia, and the quality of life for all Americans. As you can see from our agenda, we’re talking with those experts from many, many disciplines, including those outside the traditional aerospace arena.

As an example, try holding a book in your hands straight out in front of you and not moving them for one or two minutes. After a while, do your hands start to shake or move around? Imagine how hard it would be to hold your hands steady for many days in a row, or to lift something really heavy. Wouldn’t it be nice to have a really long arm that never gets tired? Well, to help out in space, scientists have designed and used robotic arms for years. On Earth, scientists have designed robotic arms for everything from moving heavy equipment to performing delicate surgery. Robotic arms are important machines that help people work on Earth as well as in space. Astronaut attached to a robotic arm on the ISS. Look at your arms once again.

  • A Launch for the International Space Station
    A launch for the International Space Station For its first mission of the year, Arianespace will launch the first Automated Transfer Vehicle (ATV), dubbed “Jules Verne”, for the European Space Agency (ESA). Right from this first launch, the ATV will play a vital role in bringing supplies to the International Space Station (ISS). Weighing more than 20 tons, this will be by far the heaviest payload ever launched by Ariane 5. An Ariane 5 ES will inject the Jules Verne ATV into a circular orbit at an altitude of 260 kilometers, inclined 51.6 degre e s . With this launch, Ariane 5 further expands its array of missions, ranging fro m scientific spacecraft in special orbits to commercial launches into geostationary orbit. The ATV is designed to bring supplies to the ISS (water, air, food, propellants for the Russian section, spare parts, experimental hard w a re, etc.), and to reboost the ISS into its nominal orbit. The ISS now weighs more than 240 metric tons, including the recently attached European labora t o r y, Columbus. After being docked to the ISS for up to six months, the ATV will be loaded with waste items by the astronauts, and sent back down. After separating from the launch vehicle, the ATV will be autonomous, using its own systems for energy (batteries and four large solar panels) and guidance (GPS, star t racker), in liaison with the control center in Toulouse. During final approach, an optical navigation system will guide the ATV to its rendezvous with the Space Station, w h e re it will automatically dock several days after launch.

  • Study of Autonomous Capture and Detumble of Non-Cooperative Target by a Free-Flying Space Manipulator Using an Air- Bearing Platform
    STUDY OF AUTONOMOUS CAPTURE AND DETUMBLE OF NON-COOPERATIVE TARGET BY A FREE-FLYING SPACE MANIPULATOR USING AN AIR- BEARING PLATFORM Lucas Santaguida A thesis submitted to the Faculty of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Applied Science Graduate Program in Mechanical Engineering York University Toronto, Ontario June 2020 © LUCAS SANTAGUIDA, 2020 Abstract This thesis developed a 3-DOF satellite simulator with an attached 3-DOF manipulator to capture and detumble a target satellite simulator. Existing systems are heavily dependent on external systems to compute the position and orientation of the chaser and target satellite simulators. Using external sensors and high-power computers allows their systems to have high accuracy and high sampling frequencies. This approach is not reflective of the challenges faced by an on-orbit servicing spacecraft as all positioning of the space vehicle is computed on-board. In addition, their systems use the same external sensors to determine the position and orientation of the target simulator and transmit it to the chaser. A true on-orbit servicing vehicle would need to sense and compute the target simulators position and orientation relative to itself. The simulator developed in this thesis addresses these issues by computing its own position using a star-tracking system and computes the relative position and orientation of the target simulator using a monocular camera. The simulator was developed to act as a testbed for on-orbit servicing technologies. Different sensors, path planning and control algorithms can be implemented to test their effectiveness before implementation on a servicing vehicle.
