    I like this podcast. Alex creates digestible episodes on what is happening “today in space.” Informative and well thought through. Interesting also learning on his insights on 3d printing and it’s applications in outer space

  • Dull

    Visit another podcast. Vague and vacuous. No information provided except for ‘I haven’t been diagnosed but’. ‘Build a solar power satellite…’. Save time and listen or read science as opposed to this nonsense.

    Everyday astronaut provides details. This podcast provides best wishes. Well intentioned and nice.
