Is anyone familiar with resources/video compilations that go into college-level detail of spacecraft, preferably free? Or is this moreso something you’d have to find at a university?

How would you compare, using everyday Earth examples like airliners or ships, the necessary structural strength of:

a) spacecraft during launch and landing?

b) spacecraft in orbit or interplanetary space?

For those of you who haven't seen this. This link follows the European Juice spacecraft. You can also follow 160+ other spacecraft, including the Europa Clipper. You can fast-forward by days or months per second, and zoom in. It has great detail on planets and moons.

The Europa Clipper is going break-neck speed to the Jupiter System. Juice is taking its time and has a much more elegant approach, and actually goes into orbit around moons. But Juice is a year late to the party.

I'm doing research on human-automation authority in spaceflight, and am trying to figure some things out.
Lets say that post lift-off, an engine gimbals incorrectly, the autopilot fails to function correctly, or something else happens resulting in a less-than-nominal/incorrect trajectory towards where ever the vessel is going.

Is it possible for human intervention to save the launch trajectory?

How much of modern spaceflight is actually automated? (I'm assuming almost 100% based on what I know about SpaceX flights).

How much of what the automated systems are doing is actually shown to the pilot/astronauts? Do modern spacecraft systems engineers care about automation transparency?

Will it just become trackable space junk? How long would we expect the majority to remain in orbit?
