About the book: year / One very unusual man pays an unexpected visit to an old friend who has considered him dead for more than half a century. Together they are preparing an experiment to influence history, and for completely practical purposes. And the main object of the experiment is the great space race that began in the middle of the 20th century. What if S.P. Korolev knew about the childhood illnesses of the “Seven” even before the first launches and did not lose two years and dozens of dead devices? What if I had kept Glushko among my comrades? What if he could put an onboard computer on the Soyuz, or even earlier ships? What if the States did not indulge the powerful naval lobby and gave Von Braun a chance to launch a satellite using available means immediately after the Soviet one? What if three quarters of the first US lunar probes had not gone “over the hill”? What if the unification and mobilization of forces for a space breakthrough had happened three years earlier? An ongoing space race between equal rivals who know in advance about their own and others’ mistakes! Where would it lead both superpowers in just a few years, when they reach the Moon together and go further, much further??
