Thought you'd like to know, MOON SHOT is back.

To commemorate Alan Shepard's 50th anniversary as the first American in Space, his and Chief Astronaut Deke Slayton's New York Times Bestseller has been republished as an enhanced ebook, including embedded video and new, untold stories about America's Apollo moon landings.

Most weren't around when Alan Shepard and his partner Edgar Mitchell took the longest walk -- more than two miles -- on the moon.
