Any of you guys ever seen "Moon Machines"? It's a multi-part documentary about the engineering behind the moon landing. Super cool.
One of my favorite of the Apollo documentaries. My favorite episode was the navigation computer.
Regarding Orion, I designed part of the pressurization system used for inflating the uprighting airbags after splashdown. Arguably not one of the sexiest functions of the spacecraft, but keep in mind that it needs to survive every part of the spaceflight including reentry and splashdown. I believe that system will be tested on this flight.
Also, in December it will fly on an Delta IV launch vehicle, not SLS which is not developed yet. Eventually it is planned to fly on SLS. I didn't watch the video, so maybe that is mentioned there.
