Planned Mercury suborbital flight. Cancelled July 1961; delays in Redstone flights meant Atlas orbital flights were imminent.
Slayton would probably have flown the fourth manned suborbital Mercury. But after the Russians began orbiting cosmonauts, NASA cancelled further suborbital flights. The MR-6 mission was cancelled by NASA administrator James Webb at the beginning of July, 1961.
