SKY WALKING: AN ASTRONAUT'S MEMOIR

With humanity and passion (and less swagger than Mike Mullane), Jones powerfully brings to life the world of the modern NASA astronaut. Confined to low Earth orbit, no longer tasked with high-profile trips to the Moon, a small corps of dedicated professional space travelers work on serious science and dream of the day they will fly into space. Countless on-the-ground training hours prepare the astronauts for the rigors of space travel practicing an extravehicular space walk in a 10-million-gallon tank or being flung around in a 100,000-horsepower centrifuge to acclimate to the eight g's of force experienced on lift-off. A tested B-52 bomber pilot and planetary scientist, Jones still feels and expresses wonder at space flight: "I was thirty-nine when I stepped out on the pad [in 1994] with the rest of the crew, but I gazed up at Endeavor with a child's amazement.... I shivered with excitement at the sight of my now-ready spaceship." While the twin tragedies of Challenger and Columbia hang over the story like a pall, Jones still manages to fire the spirit and invite the reader to imagine a place for humankind beyond planet Earth.
