The mighty Saturn V rocket that took the United States to the Moon had a lift capacity of 260,000 lb (120,000 kg) to low-Earth orbit. That’s 130 tons, or 116 “tonnes.”

So in other words NASA is prepared to spend tens of billions of dollars to deliver a rocket probably 3 years late and more billions over budget that can do what the Saturn V could do?

The Saturn V couldn’t take a person to Mars.

The Saturn V wasn't designed for a Mars mission. It was designed to attain LEO and put the CM/CSM/LM on a trajectory to the Moon.

It could never be used to do the same for a Mars mission.
