As command module pilot for the Apollo 15 mission to the moon in 1971, Al Worden flew on what is widely regarded as the greatest exploration mission that humans have ever attempted. He spent six days orbiting the moon, including three days completely alone, the most isolated human in existence. During the return from the moon to earth he also conducted the first spacewalk in deep space, becoming the first human ever to see both the entire earth and moon simply by turning his head. The Apollo 15 flight capped an already-impressive career as an astronaut, including important work on the pioneering Apollo 9 and Apollo 12 missions, as well as the perilous flight of Apollo 13. Nine months after his return from the moon, Worden received a phone call telling him he was fired and ordering him out of his office by the end of the week. He refused to leave. What happened in those nine months, from being honored with parades and meetings with world leaders to being unceremoniously fired, has been a source of much speculation for four decades. Worden has never before told the full story around the dramatic events that shook NASA and ended his spaceflight career. Readers will learn them here for the first time, along with the exhilarating account of what it is like to journey to the moon and back. It's an unprecedentedly candid account of what it was like to be an Apollo astronaut, with all its glory but also its pitfalls.

Since the beginning of civilization, the origins of the Earth and Moon have been the subjects of continuing interest, speculation, and enquiry. These are also among the most challenging of all scientific problems. They are, perhaps to a unique degree, interdisciplinary, having attracted the attention of philosophers, astronomers, mathematicians, geologists, chemists, and physicists. A large and diverse literature has developed, far beyond the capacity of individuals to assimilate adequately. Consequently, most of those who attempt to present review-syntheses in the area tend to reflect the perspectives of their own particular disciplines. The present author's approach is that of a geochemist, strongly influenced by the basic phil osophy of Harold Urey. Whereas most astronomical phenomena are controlled by gravitational and magnetic fields, and by nuclear interactions, Urey (1952) emphasized that the formation of the solar system occurred in a pressure-temperature regime wherein the chemical properties of matter were at least as important as those of gravitational and magnetic fields. This was the principal theme of his 1952 book, "The Planets," which revolutionized our approach to this subject. In many subsequent papers, Urey strongly emphasized the importance of meteorites in providing critical evidence of chemical conditions in the primordial solar nebula, and of the chemical fractionation processes which occurred during formation of the terrestrial planets. This approach has been followed by most subsequent geochemists and cosmochemists.

One of the earliest science fantasy stories ever written, From the Earth to the Moon follows three wealthy members of a post-Civil War gun club who design and build an enormous columbiad -- and ride a spaceship fired from it all the way to the moon!

"The authoritative masterpiece" (L. A. Times) on the Apollo space program and NASA's journey to the moon This acclaimed portrait of heroism and ingenuity captures a watershed moment in human history. The astronauts themselves have called it the definitive account of their missions. On the night of July 20, 1969, our world changed forever when Neil Armstrong and Buzz Aldrin walked on the moon. Based on in-depth interviews with twenty-three of the twenty-four moon voyagers, as well as those who struggled to get the program moving, A Man on the Moon conveys every aspect of the Apollo missions with breathtaking immediacy and stunning detail. A Man on the Moon is also the basis for the acclaimed miniseries produced by Tom Hanks, From the Earth to the Moon, now airing and streaming again on HBO in celebration of the 50th anniversary of Apollo 11.

From writer Stacy McAnulty and illustrator Stevie Lewis, Moon! Earth's Best Friend is a light-hearted nonfiction picture book about the formation and history of the moon—told from the perspective of the moon itself. Meet Moon! She's more than just a rock—she’s Earth’s rock, her best friend she can always count on. Moon never turns her back on her friend (literally: she's always facing Earth with the same side!). These two will stick together forever. With characteristic humor and charm, Stacy McAnulty channels the voice of Moon in this next celestial "autobiography" in the Our Universe series. Rich with kid-friendly facts and beautifully brought to life by Stevie Lewis, this is an equally charming and irresistible companion to Earth! My First 4.54 Billion Years and Sun! One in a Billion.

Explores the cycles of the sun and moon and discusses early calendars and the work of ancient astronomers and mathematicians.
