Mercury-Atlas 7, launched May 24, 1962, was the fourth crewed flight of Project Mercury. The spacecraft, named Aurora 7, was piloted by astronaut Scott Carpenter. He was the sixth human to fly in space. The mission used Mercury spacecraft No. 18 and Atlas launch vehicle No. 107-D.
The flight was for three Earth orbits, essentially a repeat of John Glenn's Mercury-Atlas 6. However, a targeting error during reentry took the spacecraft 250 miles (400 km) off-course, delaying recovery of Carpenter and the spacecraft for an hour. Carpenter was held responsible, at least in part, for the landing error. Carpenter left NASA for the Navy SEALAB program in 1964.
