In 1957 Sputnik, the world’s first man-made satellite, dazzled people as it zipped around the planet. By the beginning of the twenty-first century, more than eight thousand satellites orbited the Earth, and satellite practices such as live transmission, direct broadcasting, remote sensing, and astronomical observation had altered how we imagined ourselves in relation to others and our planet within the cosmos. In Cultures in Orbit, Lisa Parks analyzes these satellite practices and shows how they have affected meanings of “the global” and “the televisual.” Parks suggests that the convergence of broadcast, satellite, and computer technologies necessitates an expanded definition of “television,” one that encompasses practices of military monitoring and scientific observation as well as commercial entertainment and public broadcasting.

Roaming across the disciplines of media studies, geography, and science and technology studies, Parks examines uses of satellites by broadcasters, military officials, archaeologists, and astronomers. She looks at Our World, a live intercontinental television program that reached five hundred million viewers in 1967, and Imparja tv, an Aboriginal satellite tv network in Australia. Turning to satellites’ remote-sensing capabilities, she explores the U.S. military’s production of satellite images of the war in Bosnia as well as archaeologists’ use of satellites in the excavation of Cleopatra’s palace in Alexandria, Egypt. Parks’s reflections on how Western fantasies of control are implicated in the Hubble telescope’s views of outer space point to a broader concern: that while satellite uses promise a “global village,” they also cut and divide the planet in ways that extend the hegemony of the post-industrial West. In focusing on such contradictions, Parks highlights how satellites cross paths with cultural politics and social struggles.

Galileo Galilei’s Sidereus Nuncius is arguably the most dramatic scientific book ever published. It announced new and unexpected phenomena in the heavens, “unheard of through the ages,” revealed by a mysterious new instrument. Galileo had ingeniously improved the rudimentary “spyglasses” that appeared in Europe in 1608, and in the autumn of 1609 he pointed his new instrument at the sky, revealing astonishing sights: mountains on the moon, fixed stars invisible to the naked eye, individual stars in the Milky Way, and four moons around the planet Jupiter. These discoveries changed the terms of the debate between geocentric and heliocentric cosmology and helped ensure the eventual acceptance of the Copernican planetary system.
 
Albert Van Helden’s beautifully rendered and eminently readable translation is based on the Venice 1610 edition’s original Latin text. An introduction, conclusion, and copious notes place the book in its historical and intellectual context, and a new preface, written by Van Helden, highlights recent discoveries in the field, including the detection of a forged copy of Sidereus Nuncius, and new understandings about the political complexities of Galileo’s work.

Publication of Galileo's Starry Messenger in 1610, detailing startling observations with the newly invented telescope, sparked immediate furor among the astronomers and philosophers of the day. The discovery of the "Medicean stars" (the satellites of Jupiter) was pronounced a hoax, an optical illusion, a logical and theological impossibility. Stillman Drake, one of the world's foremost Galileo scholars, recreates in Telescopes, Tides, and Tactics the fascinating aftermath of the publication of the Starry Messenger. Drawing on Galileo's scientific working papers and the letters and notebooks of his colleagues, Drake presents an imaginative Galilean dialogue using the text of the Starry Messenger as a departure point for discussions of appropriate scientific method, new discoveries, and the emergence of a new world view at this early stage of the Scientific Revolution.

Drake has revised his earlier abridged translation of the Starry Messenger, and for the first time the entire work is presented here in modern English. No other edition or translation of this famous work has analyzed Galileo's recorded observations in detail, compared them with modern calculations, or explained the later use he made of them. In the accompanying fictional dialogue, Salviati, Sagredo, and Sarpi reread the Starry Messenger in 1613 and discuss events and issues raised in the three years since its publication. Much of the dialogue is based on archival materials not previously cited in English. Drake has unearthed a wealth of information that will interest the lay reader as well as the historian and the scientist—descriptions of the various and occasionally bizarre critics of Galileo, a reconstruction of Galileo's promised book on the system of the world, his tables of observations and calculations of satellite motions, and evidence for an early tide theory. It was this theory explaining tides by motions of the earth, rather than the influence of Platonic metaphysics, Drake argues that played a major role in Galileo's acceptance of Copernican astronomy.

Telescopes, Tides, and Tactics is a thorough portrait of Galileo as a working astronomer. Offering much more than a commentary on the Starry Messenger, Drake has written a novel and absorbing contribution to the history of physics and astronomy and the study of the Scientific Revolution.
