I think the main problem is repeated insertion/removal vs. semi-permanent installation.
USB connectors are designed to be inserted and removed over and over. They're held in by pressure against the connector, so they can be removed without having to push a tab or twist the connector to remove it.
UTP cables are designed to be plugged in, and then generally left alone. The UTP cable in my computer bag is in terrible shape.. the RJ45 connector is coming loose, the plastic retaining tab is broken off (so the cable often pops out of the jack on its own), etc.
I have USB devices which I've removed and inserted hundreds of times, and the connectors still work reliably.

You're absolutely right. At no point is a trip to the ISS actually scheduled, this is just the "first step" in your "training.."

That takes all the fun out of it, as far as I'm concerned.
