A poetic odyssey through space with the groundbreaking Voyager 2 probe--past Earth, into deep space and beyond. In 1977, a space probe was built to help human beings learn a little more about outer space. Soon, along with its twin, Voyager 2 slipped through the clouds and left Earth behind. The spacecraft traveled for years through the deep, infinite night. At last Voyager 2 reached its first goal: Jupiter. Then it met the spellbinding sight of Saturn. Then, going further than any previous mission, the probe visited the blue ice giants Uranus and Neptune. Past the boundaries of our solar system, Voyager 2 sails on, carrying a Golden Record for any new friends it makes in interstellar space...This lyrical, atmospheric book introduces young readers to a pioneering NASA spacecraft that has spent over forty-five years observing and exploring our galaxy. With stirring poetry, luminous art, and fascinating back matter, The Sky Is Not the Limit will inspire future scientific innovators and foster a sense of wonder at our universe.
