Not particularly riveting stuff, but I found it interesting nonetheless. It's an interview with astronaut Stephen Bowen, who is aboard the International Space Station.

The audio only in the story is somewhat tightened up, but there's also an embedded video. For that, the actual interview starts at around 5:33.

as an aside the 3D-printed rocket sorta worked. I lifted off and made it through the second stage separation, but that stage failed to fire. So it did not make it to orbit as planned. However, it did prove the concept worked.

Thank you both for posting; I'd forgotten about Relativity Space's Terran 1 launch rescheduled and 3rd time attempt at charm middle of last night. It did survive "max Q" the greatest pressure from air during launch as the rocket accelerates through the thinning atmosphere, so it's a viable concept although I'm not completely sold on a LARGER 3D rocket in the future necessarily being able to survive, but I'm not a mechanical engineer or rocket scientist and I'm sure they've done their homework.

I also feel like a lot of the space startups - and even successful commercial providers - have issues with second stages. The Terran 1 second stage as well as Japan's new MH3 rocket both had 2nd stage failures (along with, if I'm not mistaken, Virgin Orbit in their debut UK and possibly final ever flight?)
