Apollo 11 astronaut Buzz Aldrin’s courageous, candid memoir of his return to Earth after the historic moon landing and his personal struggle with fame and depression. “We landed with all the grace of a freight elevator,” Buzz Aldrin relates in the opening passages of Return to Earth, remembering Command Module Columbia’s abrupt descent into the gravity of the blue planet. With that splash, Aldrin takes readers on a journey through the human side of the space program, as one of the first two men to land on the moon learns to cope with the pressures of his new public persona. In honest and compelling prose, Aldrin reveals a side of instant fame for which West Point and NASA could never have prepared him. One day a fighter pilot and engineer, the next a cultural hero burdened with the adoration of thousands, Aldrin gives a poignant account of the affair that threatened his marriage, as well as his descent into alcoholism and depression that resulted from trying to be too many things to too many people. He didn’t realize that when he landed on his home planet his odyssey had just begun. As Aldrin puts it, “I traveled to the moon, but the most significant voyage of my life began when I returned from where no man had been before.” Return to Earth is a powerful and moving memoir that exposes the stresses suffered by those in the Apollo program and the price Buzz Aldrin paid when he became an American icon.

More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.
