  • This Podcast Will Leave You Misinformed

    This podcast is not one I would recommend to anyone, much less anyone who is very much interested in learning more about space and space adjacent topics. The conversations are framed very poorly and can in turn mischaracterize the subject matter at hand, leading to people likely coming out with inaccurate understandings of the topics discussed. more
