The Space Above Us – “A podcast about the history of NASA human spaceflight”

It's written/hosted by a systems engineer and a spaceflight enthusiast; has tight production with no ads; and often focuses on interesting or obscure aspects of space and shuttle technology or operations, that are often relatable to the world of (more terrestrial) software.
Quick scan, it looks like the average episode of "Space Rocket History" verges on ~60min, where "The Space Above Us" is about 20-30 minutes. For me, the shorter length has made it more "snackable".
