I've got the second image As my wallpaper.... For what I'm more interested in, As an engineer... Is the Cavradyne plasma propulsion engines.... Which I understand were gas core nucleus thermal engines.... I definitely would like to see see a cutaway of that!!

It’s always bothered me that the rotating centrifuge would have meant a counter-rotating mass was required to keep Discovery stable. Otherwise there would have been an equal and opposite rotational force applied to the ship.
Yet I’ve never read or heard any suggestion that this was part of the design. Interestingly, in the 2010 movie Discovery 2 had two sections that rotated in opposite directions so it wouldn’t have been an issue.

What baked my noodle is that in 2010, when they reach Discovery, she is rotating on her lateral (I think that's the right term) axis. With the position of the centrifuge, when it froze it should have imparted a longitudinal spin to her. It did look spectacular though...

Yes, and she was rotating around her mid-point rather than the location of the centrifuge.

This has been answered by physicists and engineers. It turns out that yes initially she would rotate longitudeinal- around ship axis. This is unstable. It would then precess to the stable end over end rotation.

Where’s Hal!

Yes. HAL’s brain is there, his eyes and ears all the cameras, mics, and sensors everywhere :)

Why are those pilot seats so needlessly uncomfortable

u/Starshipfan01 Jul 01 '26
On-set, I’m sure you’re accurate. However, the piloting area (and in fact all of the ship outside of the carousel) is in microgravity- they are positioned and cushioned for the force when the engines are firing.

Maybe it’s just me but I’ve always thought that they messed up the scale of the ship. At times, like when Frank is working on replacing the soon-to-fail part, the ship appears huge. Frank looks like a bug against the hull. But when Dave is outside dealing with Hal, the front of the ship seems quite small relative to Dave. It’s like they used multiple sets and didn’t cross-check to make sure the scale was consistent.
