Space Technology Grand Challenges The Space Technology Grand Challenges are an open call for cutting-edge technological solutions that solve important space-related problems, radically improve existing capabilities or deliver new space capabilities altogether. The challenges are centered on three key themes: (1) Expand human presence in space, (2) Manage in-space resources, and (3) Enable transformational space exploration and scientific discovery. These challenges are designed to initiate thought and discussion among our nation’s innovators about future NASA missions and related national needs. The challenges will be updated to serve as a reflection and long-term measure of our nation’s space technology needs.

The Broad Challenge of Space The challenges of flying in space are such that a truly radical improvement in nearly any system used to design, build, launch, or operate a spacecraft has the potential to be transformative. In our search for technologies that will radically improve our existing capabilities or deliver altogether new space capabilities, it is likely that any great leap in capability will be the result of several, integrated advances. The Space Technology development portfolio extends across all systems critical to space missions and is not limited to the specific Space Technology Grand Challenges listed above. To meet the broad challenge of maintaining a robust and vibrant space program, investments will be considered in any space technology that has the potential to be transformative. The future demands active curiosity, open minds, and a determination to resolve challenges as they present themselves. .

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.

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.

PUB DATE 2002-00-00 NOTE 18p.; Paper presented at Uplands Retirement Community (Pleasant Hill, TN, June 17, 2002). PUB TYPE Opinion Papers (120) EDRS PRICE EDRS Price MF01/PC01 Plus Postage. DESCRIPTORS *Authors; *Biographies; *Educational Background; Popular Culture; Primary Sources; Social Studies IDENTIFIERS *Conversation; Educators; Historical Research; *Michener (James A); Pennsylvania (Doylestown); Philanthropists ABSTRACT This paper presents an imaginary conversation between an interviewer and the novelist, James Michener (1907-1997). Starting with Michener's early life experiences in Doylestown (Pennsylvania), the conversation includes his family's poverty, his wanderings across the United States, and his reading at the local public library. The dialogue includes his education at Swarthmore College (Pennsylvania), St. Andrews University (Scotland), Colorado State University (Fort Collins, Colorado) where he became a social studies teacher, and Harvard (Cambridge, Massachusetts) where he pursued, but did not complete, a Ph.D. in education. Michener's experiences as a textbook editor at Macmillan Publishers and in the U.S. Navy during World War II are part of the discourse. The exchange elaborates on how Michener began to write fiction, focuses on his great success as a writer, and notes that he and his wife donated over $100 million to educational institutions over the years. Lists five selected works about James Michener and provides a year-by-year Internet search on the author.(BT) Reproductions supplied by EDRS are the best that can be made from the original document.

  • Reading the Novel of Migrancy

    Reading the Novel of Migrancy

    Reading the Novel of Migrancy Sheri-Marie Harrison Abstract This essay argues that novels like Marlon James’s A Brief History of Seven Killings, Viet Thanh Nguyen’s The Sympathizer, Colson Whitehead’s The Underground Railroad, and Mohsin Hamid’s Exit West exemplify a new form of the novel that does not depend on national identification, but is instead organized around the transnational circulation of people and things in a manner that parallels the de- regulated flow of neoliberal capital. In their literal depiction of the movement of people across borders, these four very different novels collectively address the circulation of codes, tropes, and strategies of representation for particular ethnic and racial groups. Moreover, they also address, at the level of critique, the rela- tionship of such representational strategies to processes of literary canonization. The metafictional and self-reflexive qualities of James’s and Nguyen’s novels con- tinually draw the reader’s attention to the politics of reading and writing, and in the process they thwart any easy conclusions about what it means to write about conflicts like the Vietnam war or the late 1970s in Jamaica. Likewise, despite their different settings Hamid’s Exit West and Whitehead’s Underground Railroad are alike in that they are both about the movement of stateless people across borders and both push the boundaries of realism itself by employing non-realistic devices as a way of not representing travel across borders. In pointing to, if not quite il- luminating, the “dark places of the earth,” the novel of migrancy thus calls into existence, without really representing, conditions for a global framework that does not yet exist.

    SPHERES Interact - Human-Machine Interaction Aboard the International Space Station

    SPHERES Interact - Human-Machine Interaction aboard the International Space Station Enrico Stoll Steffen Jaekel Jacob Katz Alvar Saenz-Otero Space Systems Laboratory Massachusetts Institute of Technology 77 Massachusetts Avenue, Cambridge Massachusetts, 02139-4307, USA [email protected] [email protected] [email protected] [email protected] Renuganth Varatharajoo Department of Aerospace Engineering University Putra Malaysia 43400 Selangor, Malaysia [email protected] Abstract The deployment of space robots for servicing and maintenance operations, which are tele- operated from ground, is a valuable addition to existing autonomous systems since it will provide flexibility and robustness in mission operations. In this connection, not only robotic manipulators are of great use but also free-flying inspector satellites supporting the oper- ations through additional feedback to the ground operator. The manual control of such an inspector satellite at a remote location is challenging since the navigation in three- dimensional space is unfamiliar and large time delays can occur in the communication chan- nel. This paper shows a series of robotic experiments, in which satellites are controlled by astronauts aboard the International Space Station (ISS). The Synchronized Position Hold Engage Reorient Experimental Satellites (SPHERES) were utilized to study several aspects of a remotely controlled inspector satellite. The focus in this case study is to investigate different approaches to human-spacecraft interaction with varying levels of autonomy under zero-gravity conditions. 1 Introduction Human-machine interaction is a wide spread research topic on Earth since there are many terrestrial applica- tions, such as industrial assembly or rescue robots. Analogously, there are a number of possible applications in space such as maintenance, inspection and assembly amongst others.
