As one of the first generation of NASA astronauts, John Glenn would be the first American to enter Earth's orbit. After many successful years in the U.S. orbit. After many successful years in the U.S. Senate, Glenn would shock and delight the world by returning to space almost forty years after his pioneering flight. His incredible, action-packed life story is told with great zest and is further enhanced by dozens of full-color NASA photographs.
