  • Not Spacy but love the Podcsdt

    I listen to the first half of this podcast every weeknight. I am not in the space industry and know little about it but I find the news updates fascinating. I feel like I’m learning and I had no idea of the rich news about space there is. Sometimes I listen to second half of the show but not always. A lot of that is a little “in the weeds” for me.
