Mercury Seven: 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.

The Right Stuff (film): The Right Stuff is a 1983 American epic historical drama film.  It was adapted from Tom Wolfe's best-selling 1979 book of the same name about the Navy, Marine and Air Force test pilots who were involved in aeronautical research at Edwards Air Force Base, California, as well as the Mercury Seven, the seven military pilots who were selected to be the astronauts for Project Mercury, the first manned spaceflight by the United States.  "The Right Stuff" was written and directed by Philip Kaufman and stars Ed Harris, Scott Glenn, Sam Shepard, Fred Ward, Dennis Quaid and Barbara Hershey.  Levon Helm is the narrator in the introduction and elsewhere in the film, as well as having a co-starring role as Air Force test pilot Jack Ridley.

The Right Stuff (book): The Right Stuff is a 1979 book by Tom Wolfe about the pilots engaged in U.S. postwar research with experimental rocket-powered, high-speed aircraft as well as documenting the stories of the first Project Mercury astronauts selected for the NASA space program.  "The Right Stuff" is based on extensive research by Wolfe, who interviewed test pilots, the astronauts and their wives, among others.  The story contrasts the "Mercury Seven" and their families with test pilots such as Chuck Yeager, who was considered by many contemporaries as the best of them all, but who was never selected as an astronaut.

John Glenn: John Herschel Glenn Jr. (July 18, 1921 – December 8, 2016) was a United States Marine Corps aviator, engineer, astronaut, and United States Senator from Ohio.  In 1962 he became the first American to orbit the Earth, circling it three times.

USNS Wally Schirra (T-AKE-8): 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.

Mercury 13: 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.

Revolutionary Communist Party (Turkey): Revolutionary Communist Party (in Turkish: "Devrimci Komünist Partisi") was a clandestine communist party in Turkey.  DKP was formed following the third congress of Communist Party of Turkey/Unity (TKP/B), which was held in Greece in 1989.  The founder of DKP was the general secretary of TKP/B, İbrahim Seven.  Seven became the general secretary of DKP.

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.
