Atlas MA-9 Last crewed Mercury-Atlas
Mercury-Atlas was a subprogram of Project Mercury that included most of the flights and tests using the Atlas LV-3B launch vehicle. The Atlas was also used for one Mercury flight under the Big Joe subprogram.

The Atlas launch vehicles used for Project Mercury were given a two- or three-digit number followed by a "-D", indicating that they were the "D" version of the Atlas.
