Going boldly forth as a pioneer in the fledgling field of space archaeology, Dr Alice Gorman (aka Dr Space Junk) turns the common perception of archaeology as an exploration of the ancient on its head. Her captivating inquiry into the most modern and daring of technologies spanning some 60 years — a mere speck in cosmic terms — takes the reader on a journey which captures the relics of space forays and uncovers the cultural value of detritus all too readily dismissed as junk. In this book, she takes a physical journey through the solar system and beyond, and a conceptual journey into human interactions with space. Her tools are artefacts, historical explorations, the occasional cocktail recipe, and the archaeologist’s eye applied not only to the past, but the present and future as well. Erudite and playful, Dr Space Junk reveals that space is not as empty as we might think. And that by looking up and studying space artefacts, we learn an awful lot about our own culture on earth. She makes us realise that objects from the past — the material culture produced by the Space Age and beyond — are so significant to us now because they remind us of what we might want to hold onto into the future. ‘As charming as it is expert, as gripping as it is surprising, Dr Space Junk vs The Universe deftly threads together the cosmic and the personal, the stupendousness of space with the lived experience of human beings down here.’ — Adam Roberts, author of Gradisil

A pioneering space archaeologist explores artifacts left behind in space and on Earth, from moon dust to Elon Musk's red sports car. Alice Gorman is a space archaeologist: she examines the artifacts of human encounters with space. These objects, left behind on Earth and in space, can be massive (dead satellites in eternal orbit) or tiny (discarded zip ties around a defunct space antenna). They can be bold (an American flag on the moon) or hopeful (messages from Earth sent into deep space). They raise interesting questions: Why did Elon Musk feel compelled to send a red Tesla into space? What accounts for the multiple rocket-themed playgrounds constructed after the Russians launched Sputnik? Gorman—affectionately known as “Dr Space Junk” —takes readers on a journey through the solar system and beyond, deploying space artifacts, historical explorations, and even the occasional cocktail recipe in search of the ways that we make space meaningful. Engaging and erudite, Gorman recounts her background as a (nonspace) archaeologist and how she became interested in space artifacts. She shows us her own piece of space junk: a fragment of the fuel tank insulation from Skylab, the NASA spacecraft that crash-landed in Western Australia in 1979. She explains that the conventional view of the space race as “the triumph of the white, male American astronaut” seems inadequate; what really interests her, she says, is how everyday people engage with space. To an archaeologist, objects from the past are significant because they remind us of what we might want to hold on to in the future.

If we send a message into space, will extraterrestrial beings receive it? Will they understand? The endlessly fascinating question of whether we are alone in the universe has always been accompanied by another, more complicated one: if there is extraterrestrial life, how would we communicate with it? In this book, Daniel Oberhaus leads readers on a quest for extraterrestrial communication. Exploring Earthlings' various attempts to reach out to non-Earthlings over the centuries, he poses some not entirely answerable questions: If we send a message into space, will extraterrestrial beings receive it? Will they understand? What languages will they (and we) speak? Is there not only a universal grammar (as Noam Chomsky has posited), but also a grammar of the universe? Oberhaus describes, among other things, a late-nineteenth-century idea to communicate with Martians via Morse code and mirrors; the emergence in the twentieth century of SETI (the search for extraterrestrial intelligence), CETI (communication with extraterrestrial intelligence), and finally METI (messaging extraterrestrial intelligence); the one-way space voyage of Ella, an artificial intelligence agent that can play cards, tell fortunes, and recite poetry; and the launching of a theremin concert for aliens. He considers media used in attempts at extraterrestrial communication, from microwave systems to plaques on spacecrafts to formal logic, and discusses attempts to formulate a language for our message, including the Astraglossa and two generations of Lincos (lingua cosmica). The chosen medium for interstellar communication reveals much about the technological sophistication of the civilization that sends it, Oberhaus observes, but even more interesting is the information embedded in the message itself. In Extraterrestrial Languages, he considers how philosophy, linguistics, mathematics, science, and art have informed the design or limited the effectiveness of our interstellar messaging.

Grab your towel and hitchhike across the galaxy with Australia's most popular scientist Dr Karl Kruszelnicki. Learn about Dr Karl, the universe and everything, and discover how air-conditioning is sexist, how you can kill a spinning hard drive by shouting at it and how space junk is threatening our future capabilities for space travel. Could there be life on one of Saturn's moons? How much power could you collect from all the lightning on Earth? Why do books have book-smell? Why is 10 per cent of the Earth's land area prone to sinkholes? Why are some people chronically late? What would happen if the Earth stopped spinning? Why do most people hardly remember anything from the first half-a-dozen years of their life? How close are we to the Artificial Uterus? Why do some songs turn into "earworms" and stick inside your brain? Why does your hotel room access card get wiped so easily? And is your home WiFi really spying on you?

The next frontier in space exploration is Mars, the red planet--and human habitation of Mars isn't much farther off. Now the National Geographic Channel goes years fast-forward with "Mars," a six-part series documenting and dramatizing the next 25 years as humans land on and learn to live on Mars. This companion book to the series explores the science behind the mission and the challenges awaiting those brave individuals. Filled with vivid photographs taken on Earth, in space, and on Mars; arresting maps; and commentary from the world's top planetary scientists, this fascinating book will take you millions of miles away--and decades into the future--to our next home in the solar system.
