Ezhavathu Manithan (lit.
 "The Seventh Man") is a 1982 Indian Tamil film co-written and directed by K. Hariharan.
 Inspired by a real-life incident, the film focuses on environmental pollution and exploitation of industrial workers.
 Starring Raghuvaran in his first lead role, it features a host of newcomers playing other prominent roles.
 The film's soundtrack was made up from an album composed by L. Vaidyanathan with the lyrics of Tamil poet Subramania Bharati.
A Seventh Man is a book, in the form of photography and text by John Berger and Jean Mohr, on migrant workers in Europe.
 It was first published in 1975.
Joseph Albert "Joe" Walker (February 20, 1921 – June 8, 1966) flew the world's first two spaceplane flights in 1963, thereby becoming the United States' seventh man in space.
 Walker was a Captain in the United States Air Force, an American World War II pilot, an experimental physicist, a NASA test pilot, and a member of the U.S. Air Force Man In Space Soonest spaceflight program.
 His two X-15 experimental rocket aircraft flights in 1963 that exceeded the Kármán line – the altitude of 100 km , generally considered to mark the threshold of outer space – qualified him as an astronaut under the rules of the U.S. Air Force and the Fédération Aéronautique Internationale (FAI).
Charles "Pete" Conrad Jr. (June 2, 1930 – July 8, 1999), (Captain, USN), was an American NASA astronaut, naval officer and aviator, test pilot, and during the Apollo 12 mission became the third man to walk on the Moon.
 He set an eight-day space endurance record along with his Command Pilot Gordon Cooper on the Gemini 5 mission, and commanded the Gemini 11 mission.
 After Apollo, he commanded the Skylab 2 mission (the first manned one), on which he and his crewmates repaired significant launch damage to the Skylab space station.
 For this, President Jimmy Carter awarded him the Congressional Space Medal of Honor in 1978.
Double Star is a joint satellite based space mission by the China National Space Administration (CNSA) and the European Space Agency (ESA).
 It is the first space mission launched by China to investigate Earth's magnetosphere.
 It consists of two satellites: an Equatorial satellite (TC-1) and Polar satellite (TC-2).
 Double Star follows in the footsteps of ESA's Cluster mission by studying the effects of the Sun on the Earth's environment.
 After a nominal mission of one year (from the launch of TC-2 in July 2004), the Double Star mission was extended twice by both agencies till the end of September 2007.
X-15 Flight 91 was a 1963 American manned mission, and the second and final flight in the program to achieve sub-orbital spaceflight—a flight over 100 km in altitude—which was previously achieved during Flight 90 a month earlier.
 It was the highest flight of the X-15 program.
 It was the first flight of a reused spacecraft, as plane number three flew the previous sub-orbital flight on July 19.
 This mission was piloted by Joseph A. Walker on August 22, 1963, with the air-launch occurring from a modified Boeing B-52 Stratofortress support plane over Smith Ranch Dry Lake, Nevada, United States.
 Walker piloted the X-15 to an altitude of 107.96 km and remained weightless for approximately five minutes.
 The altitude was the highest manned flight by a spaceplane to that time and remained the record until the 1981 flight of Space Shuttle Columbia.
 Walker landed the X-15 about 12 minutes after it was launched, at Rogers Dry Lake, Edwards Airforce Base, in California.
 This was Walker's final X-15 flight.
STS-26 was the 26th NASA Space Shuttle mission and the seventh flight of the orbiter "Discovery".
 The mission launched from Kennedy Space Center, Florida, on 29 September 1988, and landed four days later on 3 October.
 STS-26 was declared the "Return to Flight" mission, being the first mission after the Space Shuttle "Challenger" disaster of 28 January 1986.
 It was the first mission since STS-9 to use the original STS numbering system, the first to have all its crew members wear pressure suits for launch and landing since STS-4, and the first mission with bailout capacity since STS-4.
 STS-26 was also the first all-veteran crew mission since Apollo 11, with all of its crew members having flown at least one prior mission.
STS-61-C was the twenty-fourth mission of NASA's Space Shuttle program, and the seventh mission of Space Shuttle "Columbia".
 It was the first time that "Columbia", the first operational orbiter to be constructed, had flown since STS-9.
 The mission launched from Florida's Kennedy Space Center on 12 January 1986, and landed six days later on 18 January.
 STS-61-C's seven-person crew included the second African-American shuttle pilot, future NASA Administrator Charles Bolden, the first Costa Rican-born astronaut, Franklin Chang-Diaz, and the second sitting politician to fly in space, Representative Bill Nelson (D-FL).
 It was the last shuttle mission before the Space Shuttle "Challenger" disaster, which occurred just ten days after STS-61-C's landing.
Mercury-Atlas 9 was the final manned space mission of the U.S. Mercury program, launched on May 15, 1963 from Launch Complex 14 at Cape Canaveral, Florida.
 The spacecraft, named Faith 7, completed 22 Earth orbits before splashing down in the Pacific Ocean, piloted by astronaut Gordon Cooper, then an Air Force major.
 The Atlas rocket was No. 130-D, and the Mercury spacecraft was No. 20.
 This mission marks the last time an American was launched alone to conduct an entirely solo orbital mission.

Question: In what year did the mission, piloted by the seventh man in space, occur?
Answer: 1963
