also Sheyna is such an incredible person!

Gary was on *point* in this episode. He brought the right questions and the right energy to the perfect kinds of questions to ask this particular person to get the most out of their specific circumstances.

Dr. Sheyna Gifford is such a wonderful guest, glad to have her back on StarTalk. She's got the smarts, she's got the comedy chops, and she's got a very passionate and enthusiastic way of talking that makes her an absolute delight.

We love hearing that you learned something! :)

[@ricardocnassif]

Dr. Sheyna Gifford is a force of nature. It'd be fantastic to have her back on the show in a not too distant future.

[@carolvega1982]

This is probably one of the best episodes of Startalk! A great mash up of an astrophysicist, comedian, sports commentator, football player, astronaut! So many perspectives on the physical, spiritual, and experiences of space travel and humanity in general all in one episode!!! BRAVO!!!! And encore, please!!!! 💋🤌 Thank you for this!!!

[@justinratcliffe947]

I met Leland Melvin at my local Barnes & Noble in 2017. Bought a copy of his book Chasing Space. Got his autograph and even my picture taken with him.

[@jackeddaniel242]

Glad you had Leland Melvin on the show, first heard of him and his journey watching the One Strange Rock series. It's also quite fascinating how physiologically tethered we are to the Earth, makes me wonder how humans would evolve over multiple generations in space

[@kassistwisted]

I'm sure this has been said many times before, but that is my favourite part of The Expanse book series. It imagines how humans born and raised in space would diverge from humans born on Earth and how those adaptations both helped and hindered them. I wish more sci-fi shows would explore this (although I recognise it's really expensive to CGI for the screen).

[@Borgone107]

This is the best podcast of all time. Where else can you increase your knowledge of all things science and laugh so much at the same time. Neil and Chuck are the best. Great Job!!! 👍😊👏

Hello Dr. Tyson! Just writing this up to say thanks for being an influence all these years. Been a huge fan and this year I’ve started my journey through college. Pursuing a degree in Physics! Strongly leaning towards Astrophysics. So thanks for being such a good influence in helping me see what I’ve wanted to do.

What happens to the sweat that’s given off when you exercise in space? Is there suction in the workout area that catches it? Or does it just float off everywhere? Especially from the skin areas not covered by clothes to trap it

[@nihilisticpuppy3799]

I heard in an interview with Scott Kelly that the I.S.S. is designed to absorb any moisture that is present in it's air, to maximize how much water they can recycle. So if any sweat floats aways, it will be filtered and reused on the space station. Plus, I'm pretty sure they also just use towels if they happen to be sweating too much.

[@aprylvanryn5898]

Crazy it cost 2,200,000 to send one person to space. We really need to fix this cost issue.

[@asquare9316]

Space is hard. Here we are, stuck at the bottom of a gravitational well. We have to do work to get enough kinetic energy to get even partway up out of that well to get to LEO. Costs a lot of money.

[@ashtreylil1]

One person who was rigorously physically conditioned using cutting edge techniques and educated by experts for years was sent in an aluminum can on top of an explosion of hundreds of tons of fuel accurately being guided 60 miles in 10 minutes into a radioactive, freezing, searing, blinding, vacuum and returned alive. This is amazing considering a f22 jet costs over $120 million, so we could fly a whole NFL team for the cost of one.

[@stanleydelano9169]

Good one 👍

[@Reno_Slim]

Just wondering about the 2 hours of daily exercise on the station is that all in one go or can it be done in intervals like 15-30 minutes at a time?

I still think a tension suit with magnetic footwear and a railing is a superior idea. It would allow astronauts to more effectively use their time in space by continually simulating resistance to their muscles, as they would feel on earth throughout the day, reducing the amount of time they would need to "work out".

[@TikkyTakMoo]

15:14 This sounds reminiscent of living on a boat and then walking around and feeling as though the world around is moving, which causes a loss of balance. I forget what it's called but it's definitely a.. "trip" 😁🤞

[@W1ngSMC]

That wouldn't work. You don't actually work out if your legs are glued to the floor. (your body is not weighing on your legs ...) The only thing that could work according to our current knowledge is a spinning station.

[@Izz_1321]

@@TikkyTakMoo strong magnetics up in the iss will probably mess up lots of thing pf there. No good

Wait a second, so the space station has 90% of earth's gravity, but astronauts still have this insane amount of muscle and bone changes? 10% makes that much of a difference?

[@W1ngSMC]

Because gravity is the centripetal acceleration keeping the station in orbit. A falling plane also has most of earth's gravity yet you are still "floating" inside of it. It isn't gravity keeping your bones "busy", but your weight.

[@kevinwalden4288]

@@W1ngSMC nice, I figured it was something akin to that. The fact that your bones are having to actively support your weight since sitting/standing etc is constantly applying stress to them

[@Gerard1971]

Compared to sea-level (r =6371000 m from the center of earth), the gravity at the altitude of the ISS (420 km or r=6791000 m) is 88% compared due to the inverse r squared in Fg = G*M1*M2 / r squared: 6371000 squared / 6791000 squared = 0,88. However, the ISS is orbiting the earth at a speed at which the centripetal force is exactly the same as the force of gravity, causing zero g or micro gravity. To calculate this speed: Fg = (G * mass earth * mass iss) / (r squared) Fc = (mass iss * (v squared)) / r If you set Fg = Fc, you can derive the speed at which the ISS must travel: v = square root (G * Mass earth / r) (as you can see, the mass of the ISS has no impact on the orbital speed) Plug in the numbers: square root of ( (6.67×10^−11 * 5.98×10^24) / 6791000) = 7663 m/s or 27586 km/h (17141 mph).

[@mmgibson1]

Chuck might be more useful than sitting in a cushy chair and drinking coffee. I bet Dr. Gifford knows that laughter is the best medicine - Chuck may be telling jokes to astronauts someday to help them focus more on the silliness of their situation instead of the seriousness. They do already like to play with zero gravity effects when they have the chance.

What if the MetaVerse creates a real time VR Experience with a satellite that traveled the Universe because none of us are going to live long enough to get most places in space and back. Humans only live maybe 70-80 yrs. So in the MetaVerse it could go on for hundreds of years with multiple people researching and experiencing real time space in a different part of the universe.
