    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.

Talking Points

Recent interactions between the hosts and their guests.

NASA Sending Crew 11 Home Early Jan 14th | Astronaut Med Alert Conference from LIVE Hangout Jan 8th
Q: Will NASA consider having an actual medical officer on board the ISS in future space missions?
All astronauts go through extensive medical training, but having a doctor on board would not necessarily change our response to medical issues.
NASA Sending Crew 11 Home Early Jan 14th | Astronaut Med Alert Conference from LIVE Hangout Jan 8th
Q: Can you say if this medical issue is related to an injury that was sustained on Space Station?
This is not an operational issue. The astronaut's medical condition is unrelated to operations on board.
The Road to NASA Administrator | Jared Isaacman Passes Senate Committee AGAIN
Q: Will you execute the funds appropriated by Congress for NASA's critical science missions exactly as Congress has directed?
Yes, sir. We will maximize the scientific value of every dollar that Congress affords the agency.
NASA & Interstellar 3I-ATLAS | Recap w/ My Thoughts & Press Q&A
Q: Did any of you seriously take seriously the proposition that this could be an alien spacecraft?
We certainly haven't seen any technosignatures or anything from it that would lead us to believe it was anything other than a comet.
NASA & Interstellar 3I-ATLAS | Recap w/ My Thoughts & Press Q&A
Q: Based on your latest observation, what more can you tell us about the potential shape of the comet? Can you fine tune any more on how big or small it might be, origin, all that sort of thing?
The size of the nucleus still has yet to be pinned down, but it's estimated to be somewhere in the range of a couple of thousand feet to a couple of miles in diameter.
