Explorers of the Outer Planets: The Journey of the Pioneers and Voyagers from Earth to Neptune and Beyond

In the book «Explorers of the Outer Planets: The Journey of the «Pioneers» and «Voyagers» from Earth to Neptune and Beyond», Igor Lisov vividly recounts the history of preparation, planning, financing, launches, and flights of the «Pioneers» and «Voyagers» —... spacecraft whose mission was to explore the outer planets of the Solar System. These expeditions provided incredibly valuable information about Jupiter, Saturn, Uranus, and Neptune — celestial bodies about which human knowledge was previously quite superficial. Two «Voyagers» are still in flight today: gradually losing power, they cease to transmit signals and move further away from Earth, beyond the Solar System. These ships are never destined to return, however, on board, the «Voyagers» carry messages from Earthlings to extraterrestrial civilizations — in case such a meeting ever occurs.
