Was it Atlas V or Saturn V that took Apollo toward the moon?
Saturn V.
Saturn V, a much larger bird, which could put much more payload into near earth orbit.
The Atlas V rocket is the latest in a series of rockets with different sizes and configurations with the Atlas name. The original was built for the Mercury space program in order to launch the Mercury astronauts. The first two astronauts did not use the Atlas, but the smaller Redstone, but John Glenn was the first to ride the Atlas into orbit. After the Mercury program, I don't think they have ever launched another human, but have been in service ever since launching unmanned payloads.
