My bad!

To add: Orion will circle the Earth twice, then ending its test mission. A NASA spacecraft with humans on board hasn't been outside of low-Earth orbit since the last Apollo mission, over 40 years ago. This test will help bring us there and beyond.

Lots to be excited about.

But I never see things like this live... watching it on tv or youtube just isn't the same.

For some who might we wondering what's up with all the finicky delays.

Previous attempts to use this launch system in the past have resulted in *partial* failures because of cavitation and resonance - which is fairly common for rocket set ups of this size (the Soviet N1 project and the Apollo missions both had catastrophic failures due to cavitation and resonance). Pressure in particular is going to be something they'll have to be *extremely* careful about to prevent the liquid fuel they're using from forming bubbles so large that they implode (and cause damage to the rocket).

Resonance is another concern with rockets this big - where basically everything is shaking around a lot and the very noise of the rocket, and noises created by moving and flexing parts of the apparatus, can cause components to break down (and fail).

They also had a few fuel valves fail pre-launch tests - which is something, particularly NASA, is extremely paranoid about.

If you're interested in more factoids:

The launch system (not the Orion craft strapped to the top) costs 375 million dollars a pop.

This is essentially a do-over of the Apollo 4 mission, essentially proving that Orion works properly and that they've got everything sorted out.

The hardest part of these "big rocket" missions is getting the actual launch system off the ground and into space without it tearing itself apart :(

If you're launch crazy - here is what a Delta IV *heavy* taking off properly should look like: https://www.youtube.com/watch?v=oxMuxZWtiOU

The main difference here being that I assume the Orion payload is a bit heavier than your average satellite.
