Few endeavors are as technologically demanding as the design and operation of rockets and robotic spacecraft. A deep space mission is a lengthy sequence of critical events, all of which must be achieved, either in a straightforward manner or by a work around. For example, the Cassini-Huygens mission must survive in space for seven years, flying a precise course, simply to reach its target, Saturn. It could all too easily suffer an irrecoverable failure at any stage. In fact, throughout the "Space Age" a range of systems failures has frustrated missions. These have included total booster malfunction, by rocket upper stages failing to ignite or misfiring, by being stranded in parking orbit around the Earth, by being sent on the wrong trajectory, by loss of control during mid-course correction maneuvers, by failure to deploy their communication antennas, by missing their targets completely, by crash landing, and by instrumentation failures.

This book provides a concise but broad overview of the engineering, science and flight history of planetary landers and atmospheric entry probes designed to explore the atmospheres and surfaces of other planets. It covers engineering aspects specific to such vehicles which are not usually treated in traditional spacecraft engineering texts. Examples are drawn from over thirty different lander and entry probe designs that have been used for lunar and planetary missions since the early 1960s. The authors provide detailed illustrations of many vehicle designs from different international space programs, and give basic information on their missions and payloads, irrespective of the mission's success or failure. Several missions are discussed in more detail to demonstrate the broad range of the challenges involved and the solutions implemented. This will form an important reference for professionals, academic researchers and graduate students involved in planetary science, aerospace engineering and space mission development.

Lifting Titan's Veil is a revealing account of the second largest moon in our solar system. This world in orbit around Saturn is the only body in the solar system with an atmosphere strikingly similar to Earth's. Titan is like a giant frozen laboratory that may help scientists understand the first chemical steps towards the origin of life. Beginning with its discovery in 1655, the authors describe our current knowledge of Titan, including observations made before the space age, results from the Voyager missions of the 1980s, and recent revelations from the world's most advanced telescopes. Ralph Lorenz includes his personal experiences in preparing for the Cassini mission, which will reach Saturn in 2004 and release the Huygens probe into Titan's atmosphere in 2005. This book is a splendid introduction to Titan, and will appeal to anyone interested in astronomical discovery and space exploration.

For twenty-five years following the Voyager mission, scientists speculated about Saturn's largest moon, a mysterious orb clouded in orange haze. Finally, in 2005, the Cassini-Huygens probe successfully parachuted down through Titan's atmosphere, all the while transmitting images and data. In the early 1980s, when the two Voyager spacecraft skimmed past Titan, Saturn's largest moon, they transmitted back enticing images of a mysterious world concealed in a seemingly impenetrable orange haze. Titan Unveiled is one of the first general interest books to reveal the startling new discoveries that have been made since the arrival of the Cassini-Huygens mission to Saturn and Titan. Ralph Lorenz and Jacqueline Mitton take readers behind the scenes of this mission. Launched in 1997, Cassini entered orbit around Saturn in summer 2004. Its formidable payload included the Huygens probe, which successfully parachuted down through Titan's atmosphere in early 2005, all the while transmitting images and data--and scientists were startled by what they saw.One of those researchers was Lorenz, who gives an insider's account of the scientific community's first close encounter with an alien landscape of liquid methane seas and turbulent orange skies. Amid the challenges and frayed nerves, new discoveries are made, including methane monsoons, equatorial sand seas, and Titan's polar hood. Lorenz and Mitton describe Titan as a world strikingly like Earth and tell how Titan may hold clues to the origins of life on our own planet and possibly to its presence on others. Generously illustrated with many stunning images, Titan Unveiled is essential reading for anyone interested in space exploration, planetary science, or astronomy. A new afterword brings readers up to date on Cassini's ongoing exploration of Titan, describing the many new discoveries made since 2006.

This volume reviews both historical and current studies of desert whirlwinds called dust devils on Earth and Mars. These include field measurements, orbital observations, modelling of dust devil formation and structure, studies of their population and statistics, and their atmospheric and climate impact.Dust devils have captivated humankind since antiquity, and yet also assume importance in that most modern of activities, planetary exploration. The close investigation of the planet Mars by an armada of spacecraft in the last couple of decades has stimulated extensive research on these desert whirlwinds, supported by improvements in field instrumentation on Earth, laboratory experiments and powerful numerical simulations. This convergence of capability and interest stimulated the workshop 'Dust Devils on Mars and Earth', conceived by Dennis Reiss, Ralph Lorenz, Matt Balme, Lynn D. Neakrase, Angelo Pio Rossi, Aymeric Spiga and John Zarnecki, held under the auspicesof the International Space Science Institute in Bern, Switzerland, during the week of February 16–20, 2015. The workshop drew not only planetary scientists, for whom terrestrial dust devils are a convenient proxy for their Martian cousins, but also scientists studying the impact of dust on the terrestrial climate.Originally published in Space Science Reviews, Volume 203, Issue 1-4, November 2016
