SpaceX's Falcon Heavy launch will make you excited about spaceflight again

Watching a rocket launch into space is like nothing else. 

Your heart races. Your palms sweat, and when you hear that terminal count kick in – 10, 9, 8, 7... – it really hits home that this is a wondrous feat of engineering that you're fervently hoping will go right, but could also be moments away from turning into a ball of flame. 

It feels like seconds stretch into hours as you're waiting for the rocket to lift off, and then suddenly, in the blink of an eye, the rocket is in the air, moving swiftly up into the clouds.
