We Don’t Know Why Astronauts Get Motion Sick

A majority of modern astronauts experience any one of a suite of symptoms scientists collectively call Space Motion Sickness, or SMS. But despite knowing about it for nearly as long as humans have gone into space, we still don't know exactly what causes it, or how to predict which astronauts might lose their lunch.

But this channel is my favourite of sci shows 😭

[joshsickles]

I know it doesn't change the amount of content for Sci show space(I hope), but I am still sad to see it go. Sci show space was my favorite from the team.

[waylontmccann]

I remember when the Sci show first branched off into its various flavors. Has it been so long? Well, as long as we still get to see our favorite faces and get regular space news and information, I'll always be satisfied. Thanks for all of the hard work!

This is the last SciShow Space video on this channel?? I'm glad to have here to witness it so soon after it was uploaded. Looking forward to seeing the hosts on the main SciShow channel continuing their journey to teach us wonderful space facts and share fascinating space news 🖖

[jscotthatcher]

awww. well i hope the amount of the space videos doesn't slow down much. and hopefully this will help boost the viewership/reach of the main channel.

Aw man your getting rid of scishow space too:( and so soon after scishow psychology. Sad times but glad it's continuing on the main channel <3
Hopefully none of the series from this channel get axed, they are all so good!!

[JonathanMickelson]

Sad to hear the move, as there are fewer quality SpaceSci specific channels. Thank goodness PBS SpaceTime will still hold that beachhead!

[ArchAnjell]

What I liked about Sci Show Space was that it collected the space stuff in one spot. I could subscribe and not have clutter of other science stuff I wasn't interested in my feed.
And now it's gone.

Does this mean episodes will come more often? I don't mind the two channels I enjoy them both. But if they will become one, it would be nice to see a extra video or two each week. It's nice to learn about the world and universe, especially new things I'm not in the loop about.

If you use Virtual reality head sets for VR games, there is a rating for games that may cause motion sickness such as roller coaster rides or ISS simulator. Your eyes are telling you one thing and your vestibular system is telling you something else and you can become quite sick. I think that subjecting astronauts to such games would be a way to know who is subject to motion sickness or not. And it lends weight to the sight V vestibular system hypothesis.

space dizzies sound a lot like VR dizzies. takes a few days to get over the motion sickness of playing VR also. interesting to think it could be ear crystals that cause such a difficult transition on the perception of movement in uniquely different environments than we typically need to make our way through.

I love this channel! Thank you for amazing content for the past nine years! I’ll be looking forward to seeing more space stuff on the main channel!

[lovejonas]

Goodbye SciShow Space! I'm glad that you guys will still be making content on the main SciShow channel though!

[graemehirstwood]

Tis is a total bummer. I look forward eagerly to SciShow Space episodes coming out and this will leave a big hole in my viewing pleasure. Perhaps a final farewell retrospective episode should be aired?

[euchiron]

I remember hearing about tests involving simulators which showed a video feed that differed from the motion of the simulator, and that seemed to cause the greatest motion sickness. The otolith asymmetry hypothesis seems promising

[kissmeimarockstar]

A genuine thank you to everyone involved in the SciShow Space page and content, see you next time on SciShow!

[mouser]

I remember when SciShow space broke off of SciShow T-T

[jerelull]

Sea sickness is definitely a "thing", which seems related to SMS. The one thing that I noticed "water world" got *right* was "land sickness". After being on the water a few weeks, sailors definitely can get nausea from the world NOT moving constantly.

[CaptainMarvelsSon]

I watch the channels collectively not paying attention to which channel I am on, but this will probably confuse a lot of not-regular viewers.

[majorfrostbyte]

A few years back they split the patreons and I felt bad because I could only support one, so I stayed with the main channel even though I liked both. Now they are combining the two channels, so I at least feel like I'll be giving Space the love it deserves again. But I wonder how they'll handle it on Patreon. In any case, my support at the main channel will continue.
