Alfred Worden 
Astronaut Al Travels to the Moon [PDF ebook] 

As the command module pilot for the 1971 Apollo 15 mission to the Moon, Astronaut Al Worden remained in orbit to observe and take photographs while his two crewmates explored the surface. On the return-flight to Earth, he became the first person to walk in deep space. In Astronaut Al Travels to the Moon, his fourth book, Worden vividly depicts space travel as only an astronaut can. Join him for a lyrical journey to the Moon and back that captures first-hand the essence of hurtling through the cosmos, an adventure for both children and adults.
