Astronaut
The first civilian in space was Valentina Tereshkova aboard Vostok 6 (she also became the first woman in space on that mission).
Tereshkova was only honorarily inducted into the USSR's Air Force, which did not accept female pilots at that time. A month later, Joseph Albert Walker became the first American civilian in space when his X-15 Flight 90 crossed the line, qualifying him by the international definition of spaceflight. Walker had joined the US Army Air Force but was not a member during his flight. 
The first people in space who had never been a member of any country's armed forces were both Konstantin Feoktistov and Boris Yegorov aboard Voskhod 1.
STS-7
STS-7 was NASA's seventh Space Shuttle mission, and the second mission for the Space Shuttle "Challenger". During the mission, "Challenger" deployed several satellites into orbit. The shuttle launched from Kennedy Space Center on June 18, 1983, and landed at Edwards Air Force Base on June 24. STS-7 was notable for carrying Sally Ride, America's first female astronaut.STS-7 began on June 18, 1983, with an on-time liftoff at 7:33 am EDT. It was the first spaceflight of an American woman (Sally K. Ride), the largest crew to fly in a single spacecraft up to that time (five people), and the first flight that included members of NASA's Group 8 astronaut class, which had been selected in 1978 to fly the Space Shuttle. President Ronald Reagan also sent his personal favourite Jelly Belly jelly beans with the astronauts, making them the first jelly beans in space.
