Especially after what happened in Apollo 1. Time, cost, quality: choose any two.

SpaceX.
Private enterprise, though.

Manned missions to the Moon?

Well, so far manned missions to orbit. As they say in astrodynamics, when you get to Earth orbit you are half way to everywhere else in the universe. (As measured by required delta-V.)

I think some of the greatest courage came on Apollo 8 with Frank Borman, Jim Lovell, and William Anders. The first manned spacecraft to leave the relative safety and pull of earth’s orbit, eject itself to a foreign moon, circle the moon, and then have the faith in the scientists and mathematicians that a certain length and power of burn would eject a spacecraft from the lunar orbit, point it to some precise point in space such that they will hit the earth’s atmosphere at precisely the right angle and speed, and not either A burn up or B bounce off to some other point in the solar system.
Oh, and the scientists and mathematicians used slide rules.
