Hampson Monalisa Foster J.L. Curtis K.S. Daniels Les Johnson & Ken Roy Praise for A Travelers Guide to the Stars by Les Johnson: We effortlessly travel round and round our sun, and we wonder: How hard would it be, really, to travel to another star? Les Johnson shows us the rocket science wed need; thats easy enough. But then he describes with wonderful detail the Starshot nanocrafts, chipsats, Starwisps, worldships, and metamaterial LightSails that we might use. Its a flight of imagination backed up with real out-of-this-world science. Bill Nye Les Johnson is that rare breed of writer who can make rocket science comprehensible even to the layperson. He has more than paid his dues in the field, and his enthusiasm for the cause of interstellar exploration shines through. But so does his sense of humor, his humanity, and his zest for life. This is highly recommended stuff. David Weber Is humanity ready to take on the immensities outside our solar system? This travelers guide lays out methods and means that may enable our first steps into the great unknown beyond the suns familiar campfire. David Brin Praise for Mission to Methone: The spirit of Arthur C. Clarke and his contemporaries is alive and well in Johnsons old-fashioned first-contact novel, set in 2068. . . . Theres a great deal here for fans of early hard SF. Publishers Weekly Praise for The Spacetime War: Johnson, a NASA physicist, brings verisimilitude and scientific accuracy to this adventure, and his passion for the details of space travel will undoubtedly please readers looking for old-school hard science fiction. His narrative enjoys a slow-building sense of development as he gradually unravels multiple mysteries . . . Johnsons fans will find plenty to enjoy.
