Book Description
Since the beginning of space flight, the collision hazard in Earth orbit has increased as the number of artificial objects orbiting the Earth has grown. Spacecraft performing communications, navigation, scientific, and other missions now share Earth orbit with spent rocket bodies, nonfunctional spacecraft, fragments from spacecraft breakups, and other debris created as a byproduct of space operations. Orbital Debris examines the methods we can use to characterize orbital debris, estimates the magnitude of the debris population, and assesses the hazard that this population poses to spacecraft. Potential methods to protect spacecraft are explored. The report also takes a close look at the projected future growth in the debris population and evaluates approaches to reducing that growth. Orbital Debris offers clear recommendations for targeted research on the debris population, for methods to improve the protection of spacecraft, on methods to reduce the creation of debris in the future, and much more.

Book Description
This volume collects 33 papers that were presented at the international conference held at the Faculty of Arts, Charles University in November 2015 to celebrate the centenary of Bedřich Hrozný’s identification of Hittite as an Indo-European language. Contributions are grouped into three sections, “Hrozný and His Discoveries,” “Hittite and Indo-European,” and “The Hittites and Their Neighbors,” and span the full range of Hittite studies and related disciplines, from Anatolian and Indo-European linguistics and cuneiform philology to Ancient Near Eastern archaeology, history, and religion. The authors hail from 15 countries and include leading figures as well as emerging scholars in the fields of Hittitology, Indo-European, and Ancient Near Eastern studies.
