Spacepod by Carrie Nugent is hands down the best podcast about space. She interviews a different expert every week and gets them to share and explain their research. Fantastic. Hooked me from the beginning.

Some episodes are better than others, but they are always jam packed full of information.
Edit: Also, Carrie is an astronomer, so sometimes her and the guest fully geekout on a topic.
I’ve been thinking about upgrading my MK3. It was a hard choice between Prusa and bamboo. This makes the choice a bit easier.
