Question: What capsule showcased at the National Air and Space Museum was flown by the first American to orbit the Earth?
Context: The Gnome 7 Omega (commonly called the Gnome 50 hp) is a French seven-cylinder, air-cooled aero engine produced by Gnome et Rhône.  It was shown at the Paris Aero Salon held in December 1908 and was first flown in 1909.  It was the world's first aviation rotary engine produced in quantity.  Its introduction revolutionized the aviation industry and it was used by many early aircraft.  It produced 50 horsepower (37 kW) from its capacity of 8 litres (488 cubic inches).  A Gnome Omega engine powers the 1912 Blackburn Monoplane, owned and operated by the Shuttleworth Collection, the oldest known airworthy British-designed aeroplane worldwide.  A two-row version of the same engine was also produced, known as the Gnome 14 Omega-Omega or Gnome 100 hp.  The prototype Omega engine still exists, and is on display at the United States' National Air and Space Museum. The Wide Field and Planetary Camera 2 (WFPC2) is a camera formerly installed on the Hubble Space Telescope.  The camera was built by the Jet Propulsion Laboratory and is roughly the size of a baby grand piano.  It was installed by servicing mission 1 (STS-61) in 1993, replacing the telescope's original Wide Field and Planetary Camera (WF/PC).  WFPC2 was used to image the Hubble Deep Field in 1995, the Hourglass Nebula and Egg Nebula in 1996, and the Hubble Deep Field South in 1998.  During STS-125, WFPC2 was removed and replaced with the Wide Field Camera 3 as part of the mission's first spacewalk on May 14, 2009.  After returning to Earth, the camera was displayed briefly at the National Air and Space Museum and the Jet Propulsion Laboratory before returning to its final home at the Smithsonian's National Air and Space Museum. The Center for Earth and Planetary Studies is a research institute affiliated with the Smithsonian Institution.  Based in Washington, DC, the Center, which was founded in 1972, conducts scientific research related to planetary science, geophysics and the biophysical environment.  As a Regional Planetary Image Facility, the Center hosts for NASA data including images and maps of planets and their satellites.  It also houses images taken by the Space Shuttle.  Both of these date collections are accessible to researchers.  The Center, which is located at the National Air and Space Museum, curates two of its galleries, "Exploring the Planet" and "Looking at Earth", as well as contributing elsewhere in the museum. Air & Space/Smithsonian magazine is a bimonthly magazine put out by the National Air and Space Museum.  Its first publishing was in April 1986.  Because the museum is a part of the Smithsonian Institution, which puts out its own "Smithsonian" magazine, the magazine's full title is "Air & Space/Smithsonian".  Therefore, the word "Smithsonian" appears on the cover, just beneath "AIR&SPACE", in a much smaller size. The National Air and Space Museum Film Archives, part of the Archives Division at the National Air and Space Museum, Smithsonian Institution, holds over 20,000 films documenting the history of aviation and space flight. 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. Robert M. Stanley (August 19, 1912 – July 16, 1977) was an American test pilot and engineer.  He became the first American to fly a jet aircraft on October 2, 1942, as a civilian test pilot for Bell Aircraft.  He flew the Bell XP-59A Airacomet, which was the United States’ first turbojet aircraft.  The flight took place at Muroc Dry Lake, California.  The Airacomet is on display at the National Air and Space Museum in Washington, D.C. Louis Rayfield Purnell, Sr. (April 5, 1920 – August 10, 2001) was a noted curator at the National Air and Space Museum and earlier in life, a decorated Tuskegee Airman.  At the museum, he became expert in space flight artifacts, particularly spacesuits, and was instrumental in curating artifacts related to space exploration, during the 1960s and into the 1980s.  Purnell was the first African-American to become a curator at the Smithsonian Institution.  As a captain in the Army Air Corps and a fighter pilot, he served in the European and North African theater during World War II.  For his service during the war, he was awarded the Distinguished Flying Cross and the Air Medal with six Oak Leaf Clusters. Kathryn Dwyer Sullivan (born October 3, 1951) is an American geologist and a former NASA astronaut.  A crew member on three Space Shuttle missions, she was the first American woman to walk in space on 11 October 1984.  She is the most recent Under Secretary of Commerce for Oceans and Atmosphere and Administrator of the National Oceanic and Atmospheric Administration after being confirmed by the U.S. Senate on March 6, 2014.  Dr. Sullivan's tenure ended on January 20, 2017 with the swearing in of President Donald Trump.  Following completion of her service at NOAA, she was designated as the 2017 Charles A. Lindbergh Chair of Aerospace History at the Smithsonian Institution’s National Air and Space Museum. The National Air and Space Museum of the Smithsonian Institution, also called the NASM, is a museum in Washington, D.C..  It holds the largest collection of historic aircraft and spacecraft in the world.  It was established in 1946 as the National Air Museum and opened its main building on the National Mall near L'Enfant Plaza in 1976.  In 2016, the museum saw approximately 7.5 million visitors, making it the second most visited museum in the world, and the most visited museum in the United States.  The museum contains the Apollo 11 command module, the "Friendship 7" capsule which was flown by John Glenn, Charles Lindbergh's "The Spirit of St. Louis", the Bell X-1 which broke the sound barrier, and the Wright brothers' plane near the entrance.
Answer: Friendship 7
