A catalog of archaeological artifacts that have been left behind in space as a result of human exploration, this work describes the remnants of lost satellites, discarded lunar rovers, depleted rockets, and various abandoned spacecraft. The book is divided into three parts covering distinct but interconnected issues of lunar, planetary, and interstellar archaeology. In Parts I and II, individual chapters cover each space mission and provide technical notes, and, in some cases, images of the artifacts. Part III explores the archaeology of mobile artifacts in the solar system and the wider galaxy, looking particularly at the problems encountered in attempting a traditional archaeological field survey of artifacts that may remain in motion indefinitely.
