Winglee University of Colorado Boulder, Colorado Brian R. Dennis NASA Goddard Space Flight Center Greenbelt, Maryland Cover An eruptive prominence associated with the X1.6 3B flare of June 20, 1989. This event and its coronal mass ejection were well observed during the first Max '91 Campaign. This digital H-alpha image was obtained at 15:04 UT ( 4 minutes before the peak of the event in soft X-rays) by the Holloman Solar Observatory of the USAF SOON system.

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 -

Classification of Geosynchronous Objects
esoc European Space Operations Centre Robert-Bosch-Strasse 5 D-64293 Darmstadt Germany T +49 (0)6151 900 www.esa.int CLASSIFICATION OF GEOSYNCHRONOUS OBJECTS Produced with the DISCOS Database Prepared by ESA’s Space Debris Office Reference GEN-DB-LOG-00211-OPS-GR Issue 20 Revision 0 Date of Issue 28 May 2018 Status Issued Document Type Technical Note Distribution ESA UNCLASSIFIED - Limited Distribution European Space Agency Agence spatiale europeenne´ Abstract This is a status report on geosynchronous objects as of 1 January 2018. Based on orbital data in ESA’s DISCOS database and on orbital data provided by KIAM the situation near the geostationary ring is analysed. From 1523 objects for which orbital data are available (of which 0 are outdated, i.e. the last available state dates back to 180 or more days before the reference date), 519 are actively controlled, 795 are drifting above, below or through GEO, 189 are in a libration orbit and 19 are in a highly inclined orbit. For 1 object the status could not be determined. Furthermore, there are 59 uncontrolled objects without orbital data (of which 54 have not been cata- logued). Thus the total number of known objects in the geostationary region is 1582.

Remixing the Voyager Interstellar Record Or, As Extraterrestrials Might Listen
Journal of Sonic Studies 8 (2014) Sounds of Space: http://www.researchcatalogue.net/view/109536/109537 Remixing the Voyager Interstellar Record Or, As Extraterrestrials Might Listen Stefan Helmreich Contextualizing the Context In 2010, scientists claiming to belong to a dissenting faction of the Search for Extraterrestrial Intelligence (SETI) contacted Seeland Records. Calling themselves the Search for Extraterrestrial Intelligence in Exile, or SETI-X, the group claimed to have received an alien transmission of rearranged sound from the Voyager Golden Record, a phonograph album famously sent into outer space in 1977 on each of NASA’s two Voyager spacecraft (Figure 1). The Golden Record had been put together in the mid-1970s by a panel convened by astronomer Carl Sagan, and it held a program of sounds and music of Earth, representing to imagined aliens our planet’s soundscapes, voices, and musical traditions. [1] Figure 1: The Voyager Golden Record. Side 1, on left, is the analog audio program. Side 2, on right, instructions to extraterrestrials on how to play the record. [2] 1 Because the scientists of SETI-X wished to remain anonymous, Seeland sought a public voice or commentator from other quarters. Because the label had in 2003 released a CD I had created, Xerophonics: Copying Machine Music, a science- and-technology themed mix of sounds of indefinite ownership (Helmreich 2003), and because I had also written about scientific notions of extraterrestrial life (Helmreich 2006), Seeland reasoned that I might be appropriately positioned to offer thoughts on the SETI-X document. They asked me to comment, which I did in a few venues (including, among other sites, the Los Angeles Daily News [Mills 2010]. -

I’m thinking about it,” Colbert joked back, making the crowd laugh. Although Parcak may jokingly boil her work down to an easy-to-follow analogy involving Hollywood’s thrill-seeking, old-timey archaeologist and today’s most widely used, high- tech geographical information system, her work is no laughing matter.
