Mercury Capsule #10
No, this one doesn't have a "7" designation, like Freedom 7 and Friendship 7. Only six Mercury capsules went into space between 1961 and 1963, but a total of 20 were built for the program. Mercury #10 was used for flight qualification tests in a vacuum chamber. You can see this stepping stone to our first trips to space at the Evergreen Aviation Museum in McMinnville, Oregon.
