Got to be so mentally frustrating to spend hours suiting up, performing vehicle ingress and pad closeouts, vehicle fueling, then making it to 140 seconds to ignition before hearing „nevermind“. Then you have a few hours wait while they safe and drain the booster and get the closeout crew back to the pad. And that doesn’t even consider the emotional fatigue of having to redo the whole family goodbye event when you know you aren’t going to see your spouse or kids for at least six months. These people are made of sterner stuff than me.
