None of the seven Mercury astronauts flew to the moon. The Mercury program focused on sending astronauts into space for short periods of time and did not involve missions to the moon. The Apollo program, which followed the Mercury program, was responsible for sending astronauts to the moon.

Seven men were selected to be astronauts, only six actually went into space.
NASA first recruited astronauts in 1959 as part of the Mercury program, with the aim of selecting and training individuals to participate in human spaceflights. The original group of astronauts, known as the "Mercury Seven," were selected based on their experience as military test pilots.
Astronauts don't go to Mercury it's too hot and they could send probes or spacecraft there much more cheaply, safely, and easily if they really needed to.
