Helium makes the rocket lighter, like a balloon.

It's also used to pressurize the propellant tanks.

Why don't they make the whole rocket out of helium?!

Galaxy brain idea!

It is also used so that the technicians on the pad can make funny voices to lighten the mood a bit when there are launch delays. Morale is very important to a successful mission.

I sent Wraith a PM and he just sent me his 30 page thesis on why Ed Baldwin should have landed on the moon during Apollo 10.

If Ed Baldwin had been commanding that mission, we would have one the space race on his bravado alone!
