About the Author

Gerda Horneck and Petra Rettberg are the leading astrobiologists of the German Aerospace Center (DLR) and have outstanding renommee on both sides of the Atlantic. Gerda Horneck and Petra Rettberg serve as heads of the photo- und exobiology group at the Institute of Aerospace Medicine of the DLR. Their research interests focus on exo-/astrobiology, radiation/photo biology, e.g. including the effects of radiation of various kind on biological systems. Dr. Horneck has been principal investigator of several radiobiological and exobiology experiments in space on Spacelab, LDEF, EURECA, FOTON and ISS as well as coordinator of research projects for both ESA and NASA. Petra Rettberg's research activities included research projects at NASA Ames and in Japan and investigations of past and future space missions. Numerous board memberships and publications round off their portfolio. Extensive teaching experience make them ideal editors for this book.

Reviews

"...the book would be a valuable addition to the library of any institution concerned with microbiology." (Microbiology Today, November 2007) "This up-to-date resource is based on lectures developed by experts...and carefully edited by [...] leading astrobiologists..." (Lunar and Planetary Information Bulletin, December 2007) "...this is an elegantly written and edited book ... it is a good value for individual purchase." (Origins of Life and Evolution of Biospheres, December 2007)
