Question: Whichof the original Mercury Seven Astronauts has an author credit on the book Moon Shot: The Inside Sory of America's Race to the Moon?
Context: The Mercury Seven were the group of seven Mercury astronauts announced by NASA on April 9, 1959.  They are also referred to as the Original Seven or Astronaut Group 1.  They piloted the manned spaceflights of the Mercury program from May 1961 to May 1963.  These seven original American astronauts were Scott Carpenter, Gordon Cooper, John Glenn, Gus Grissom, Wally Schirra, Alan Shepard, and Deke Slayton. Smart was the debut album of English Britpop group Sleeper, released on 14 March 1995 by Indolent Records.  It was mixed by Stephen Street.  The album's sleeve photo was of the Mercury Seven astronauts. Mercury 13 refers to thirteen American women who, as part of a privately funded program, underwent some of the same physiological screening tests as the astronauts selected by NASA on April 9, 1959 for Project Mercury.  The term was coined in 1995 by Hollywood producer James Cross as a comparison to the Mercury Seven name given to the selected male astronauts; however, the Mercury 13 were not part of NASA's astronaut program, never flew in space and never met as a group. Captain John Henry Ebersole, M.D., MC USN (26 January 1925 – 23 September 1993) a pioneer in submarine medicine and radiation oncology, selected by Admiral Rickover to serve as medical officer aboard the US Navy's first two nuclear powered submarines, the USS "Nautilus" and the USS "Seawolf."  He was the radiologist for NASA that screened the Mercury Seven astronauts for Project Mercury.  Ebersole was the radiologist responsible for the x-rays taken during the autopsy of John F. Kennedy on 22 November 1963 at Bethesda Naval Medical Center. Moon Shot: The Inside Story of America's Race to the Moon is a book written by Mercury Seven astronaut Alan Shepard, with NBC News correspondent Jay Barbree and Associated Press space writer Howard Benedict.  Astronaut Donald K. "Deke" Slayton is also listed as an author, although he died before the project was completed and was an author in name only.  The book was published in 1994.  It was turned into a television miniseries that aired on TBS in the United States in 1994.  The miniseries was narrated by Barry Corbin (as Slayton) and featured interviews with several American astronauts as well as a few Russian cosmonauts.  Slayton died before the miniseries completed production in 1993 and the miniseries is dedicated to his memory. Geraldyn ("Jerrie") M. Cobb (born March 5, 1931 in Norman, Oklahoma) is an American aviator.  She was also part of the "Mercury 13," a group of women selected to undergo physiological screening tests at the same time as the original Mercury Seven astronauts, as part of a private, non-NASA program. Donald Kent "Deke" Slayton (March 1, 1924 – June 13, 1993), (Major, USAF) was an American World War II pilot, aeronautical engineer, test pilot who was selected as one of the original NASA Mercury Seven astronauts, and became NASA's first Chief of the Astronaut Office. Walter Marty "Wally" Schirra Jr. (March 12, 1923 – May 3, 2007), (CAPT, USN), was an American naval officer and aviator, aeronautical engineer, test pilot, and one of the original seven astronauts chosen for Project Mercury, United States first effort to put humans in space.  He flew the six-orbit, nine-hour Mercury-Atlas 8 mission on October 3, 1962, becoming the fifth American, and the ninth human, to ride a rocket into space.  In the two-man Gemini program, he achieved the first space rendezvous, station-keeping his Gemini 6A spacecraft within 1 ft of the sister Gemini 7 spacecraft in December 1965.  In October 1968, he commanded Apollo 7, an 11-day low Earth orbit shakedown test of the three-man Apollo Command/Service Module.  He was the first person to go into space three times, and the only person to have flown in Mercury, Gemini, and Apollo, logging a total of 295 hours and 15 minutes in space.  He retired from the U.S. Navy at the rank of Captain and from NASA after his Apollo flight, becoming a consultant to CBS News for its coverage of the subsequent Apollo flights.  He joined Walter Cronkite as co-anchor for the seven Moon landing missions. Auckland Energy Consumer Trust (AECT), renamed Entrust in June 2016, is a trust for electricity consumers in Auckland, New Zealand.  Formed in 1993 as sole owner of the original Mercury Energy Limited, it is now majority owner of electricity and gas distributor Vector Limited, a child of the original Mercury, the other child being the retailing division of Mercury Energy.  The Trust will be wound up in 2073 (80 years after its formation) and its assets transferred to the local government authority or authorities in the Trust district (at present this would be Auckland Council).  There have been calls for the Trust to be wound up sooner. USNS "Wally Schirra" (T-AKE-8) is a "Lewis and Clark"-class dry cargo ship of the United States Navy, named in honor of Captain Wally Schirra (1923–2007), one of the Mercury Seven astronauts, who flew three times in space, on Mercury 8, Gemini 6A, and Apollo 7.
