Alexander, Editor Marshall Space Flight Center • MSFC, Alabama National Aeronautics and Space Administration Marshall Space Flight Center ° MSFC, Alabama 35812 August 1996 PREFACE The effects of the natural space environment on spacecraft design, development, and operation are the topic of a series of NASA Reference Publications currently being developed by the Electromagnetics and Aerospace Environments Branch, Systems Analysis and Integration Laboratory, Marshall Space Flight Center. This primer provides an overview of seven major areas of the natural space environment including brief definitions, related programmatic issues, and effects on various spacecraft subsystems. The primary focus is to present more than 100 case histories of spacecraft failures and anomalies documented from 1974 through 1994 attributed to the natural space environment. A better understanding of the natural space environment and its effects will enable spacecraft designers and managers to more effectively minimize program risks and costs, optimize design quality, and achieve mission objectives. .o° 111 TABLE OF CONTENTS -

Testing the Theory of Radiation Belt Electron Loss by Hiss and Electromagnetic Ion Cyclotron Waves
c Copyright 2019 Ling Zheng Testing the theory of radiation belt electron loss by hiss and electromagnetic ion cyclotron waves Ling Zheng A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2019 Reading Committee: Michael P. McCarthy, Chair Robert Holzworth Robert Winglee Program Authorized to Offer Degree: Earth and Space Sciences University of Washington Abstract Testing the theory of radiation belt electron loss by hiss and electromagnetic ion cyclotron waves Ling Zheng Chair of the Supervisory Committee: Professor Michael P. McCarthy Department of Earth and Space Sciences Hiss, chorus and electromagnetic ion cyclotron waves (EMIC wave) are three major wave modes that are widely investigated and included in the radiation belt electron models to explain electron precipitation. The quasi-linear theories of electron loss through pitch angle diffusion by hiss and EMIC waves were proposed in 1970s. Since then the testing of the theories is still going on though some progresses had been made. Comparison of theoretical predictions to electrons distribution at loss cone is one effective way to evaluate the theories. The main obstruction of loss cone testing was from the lack of measurements of the electron loss cone distribution with enough pitch angle and energy resolution and simultaneous wave activities at the heart of radiation belt. This thesis is devoted to testing the hiss and EMIC waves diffusion theories from the perspective of the electron loss cone distribution by utilizing the previously unnoticed overlap of UARS and CRRES missions in 1991. The conclusions are as following: (1) Two cases showing the consistency between quasi-linear theory of hiss diffusion and observed loss cone distribution are found. -

Closing Comments
Closing Comments The concept of a Shuttle supporting the assembly of a space station was not an entirely new idea when Space Station Freedom was authorized in 1984. Such concepts had been evaluated during the late 1960s, as the United States and the Soviet Union competed in the race to the Moon. By the early 1970s, the two nations were on more friendly terms and keen to participate in a joint project as Apollo was being phased out and a series of Salyut space stations were being introduced. The American proposal for an Apollo to dock with a Salyut was rejected, as was a proposal to have a Soyuz dock with Skylab. So Apollo docked with Soyuz in the summer of 1975. That program was so successful that talks began almost immediately to assess the pros- pects for a Shuttle-Salyut docking in the early 1980s. In parallel, NASA devised plans for the Shuttle to reactivate Skylab. Neither of these proposals bore fruit. By the early 1980s, the idea of using a Shuttle to assemble and resupply a large space station remained, and would become the lynchpin of the Space Station Freedom before plans for that, too, were revised. By the time of the collapse of the Soviet Union in 1991 the assembly of Mir had been underway for several years. But Russia, which inherited the station and the spacecraft which serviced it, was hard pressed to continue the requisite funding. Looking back two decades to the 1990s, the merger of the American Shuttle and the Russian space station programs seems so logical, since they complemented each other. -
Advances in Space Research Forecasting the Impact of an 1859
Advances in Space Research Forecasting the Impact of an 1859-calibre Superstorm on Satellite Resources Sten Odenwald1,2, James Green2, William Taylor1,2 1. QSS Group, Inc., 4500 Forbes Blvd., Lanham, MD, 20706. 2. NASA, Goddard Space Flight Center, Greenbelt, MD 20771 Submitted: June 30, 2005, Accepted: September 25, 2005 Abstract: We have developed simple models to assess the economic impacts to the current satellite resource caused by the worst-case scenario of a hypothetical superstorm event occurring during the next sunspot cycle. Although the consequences may be severe, our worse-case scenario does not include the complete failure of the entire 937 operating satellites in the current population, which have a replacement value of ~$170-230 billion, and supporting a ~$90 billion/year industry. Our estimates suggest a potential economic loss of < $70 billion for lost revenue (~$44 billion) and satellite replacement for GEO satellites (~$24 billion) caused by a ‘once a century’ single storm similar to the 1859 superstorm. We estimate that 80 satellites (LEO, MEO, GEO) may be disabled as a consequence of a superstorm event. Additional impacts may include the failure of many of the GPS, GLONASS and Galileo satellite systems in MEO. Approximately 97 LEO satellites, which normally would not have re-entered for many decades, may prematurely de-orbit by ca 2021 as a result of the temporarily increased atmospheric drag caused by a superstorm event occurring in ca 2012. The $100 billion International Space Station may lose significant altitude, placing it in critical need for re-boosting by an amount potentially outside the range of typical Space Shuttle operations, which are in any case scheduled to end in 2010.
