- Q&A with the Crew: • CU Boulder panel and Q...
Today we're discussing short-radius artificial gravity: everyone's favorite technology to criticize. In all seriousness, an experiment will be flying on the Polaris Dawn mission later this year that is going to answer the biggest open question about artificial gravity. I'm extremely excited and I hope you are too!

***Addendum, Hasn't some of this already been done by the ESA astronaut Tim Peake on the ISS. RUclips Video "Spinning Fast In Space Make You Dizzy? Astronaut Experiment | Video" My spin rate estimate is 90 RPM do a count and see if you come up with the same number...;-)
Oh wow, I had not seen that! That’s very promising. It sounds like he only moved his head once and did feel the cc illusion but didn’t continue. It’s still much better than it would have been on earth which is interesting. This experiment should give us a more systematic breakdown especially with multiple head movements
You could say they are going to _"Take the spacecraft out for a SPIN."_ 😉
I was at that talk! Wish I had met you during my time at CU - I did a project for Allie's EVA class on how to do a safe artificial gravity EVA on some hypothetical AG station needing servicing
This channel is amazing. I wish I found it sooner.
And another variable is that there is a very notable 1g force going downwards through the test subjects when building centrifuges here on earth.
One thing that people could be doing now, which I'm not sure we're doing, is to simulate the weather inside of a rotating space colony. I'm not so sure that the weather inside a full scale O'Neill colony would actually be pleasant.
That’s interesting, I couldn’t go too deep into weather but maybe I could look into air flow at different scales
@@ConHathy The way O'Neill colonies are lit will be very significant. The designs from the 1970's and earlier used windows. However, more recent designs use LEDs powered by solar panels. This has huge benefits in terms of structural integrity. The LEDs, even though they are efficient, would still produce a significant amount of heat. If the lighting is located at the spin axis, then I would expect air currents to not cool down the lights. Instead, the hot air would stagnate there. In fact, thinking along those lines, it seems like it would be hard to get air to circulate in general. I wonder if some open source weather modeling software might be tweaked, such that it could simulate weather in an O'Neill colony.
@@stcredzeroYou should check out the novel _Rendezvous With Rama,_ by Arthur C Clarke. It's about a human mission to explore a derelict alien O'Neill cylinder that passes through the solar system from deep space. It's been 20 years since I read it, but IIRC, there is a midship "sea" that circumnavigates the cylinder. This sea is frozen when the astronauts first arrive, but it melts from the bottom. The released water vapor forms a temporary "hurricane" aligned along the axis of the ship.
what an excellent channel! subscribed
Been waiting for this video lol
Absolutely awesome!!! Can't wait till July!!! Con thank you so much for the new video...;-) I will work on a table to quantify Coriolis force vectors, and how passenger movents change them. Coriolis push measured in direction, and "g." See the chart from the rotating room study in Pensacola Florida back in the 1970's. The bed rest study was done by ESA correct?
Yes, it was a combined effort between NASA and ESA
Here is an article from NASA: www.nasa.gov/feature/one-small-step-without-ever-leaving-bed/
Here is the actual paper: pubmed.ncbi.nlm.nih.gov/33811556/
What about cochlear implants to correct for the vestibular system confusion
I’m not sure, are they capable of “numbing” your inner ear, I have only seen them used to stimulate it
I wonder how much you can detect motion sickness in mice or other creatures, how it compares to humans, etc for maybe animal testing. You still might
Need to make same length centrifuge but feeding etc mice less than human, motor can be less powerful, mass savings, astronauts can do other things while experimenting, etc
I don’t think it would be very easy to detect assuming they get sick the same way as humans which seems unlikely. Being bipedal and large I would expect us to be more sensitive to lower speeds, also we get uncomfortable long before we’re physically sick
Do mice barf? Maybe that could be the way to detect motion sickness.
Just invent gravity in space like Newton did on earth!
Bad Jokes aside, just stumbled on your channel and man the content is a pure Goldmine!
I wonder if there would be anything of value to be learned from marine mammals (without performing experiments on living animals} re; bone and muscle strength. They experience virtually no gravity while in water. Wouldn't help with spinning of course.
Did you get new glasses?
Nope, rewatch all of my videos and you’ll see them in there somewhere
