A Man From Planet Earth (eBook)

Sometime in the not-too-distant future ... unbeknownst to Earth, the Galaxy is home to a number of spacefaring societies. This confederation enforces a strict protocol forbidding any contact with civilizations that have not yet achieved both a substantial spacefaring capability and sufficient maturity to control the technology explosion before triggering their own extinction.

While this policy is intended to only bring in peaceful new members, matters change entirely when the confederation is threatened by some unknown entity - is the menace real or imagined? The confederation decides to break with the rules and sends a delegate to Earth to hire one of the supposedly belligerent Earthlings to investigate and to revive the confederation's long-unused starfleet. The Earthman agrees, but demands a high price: should he succeed, the confederation will have to accept Earth as a new member. As the threat becomes ever more acute, the question soon becomes which mission will prove harder - saving the confederation or convincing it to accept the deal!

The extensive appendix, written in non-technical language, reviews the scientific and technological topics underlying the plot - ranging from the Fermi paradox, space travel and artificial/collective intelligence to theories on possible universal convergences in technological and biological development.

Professor Giancarlo GENTA, an expert in space flight technology, holds degrees in Aeronautic Engineering and Space Engineering (his thesis was on electric propulsion orbital transfers). Until 1996 he was head of the Mechanics Department of the Politecnico (Technical University) of Turin, in Italy. He is Director of the Italian SETI (Search for Extraterrestrial Intelligence) study center and is a full member of the International Academy of Astronautics. He has written more than 300 scientific papers and 11 scientific books, some used as textbooks in Italian and American Universities and translated into Russian. Among his popular science book are 'Space: The Final Frontier?', published by Cambridge University Press in 2002, as well as 'Lonely Minds in the Universe - The Search for Extraterrestrial Intelligence' (2007) and the Science Fiction Novel 'The Hunter' (2014), both published by Springer.
