Welcome toe watch Mojo.

And today we'll be counting down our picks for the top 10.

Craziest things you didn't know about living in space.

So just a Ziff.

I started crying, my eyes full of tears, but you can see it just forms a ball on my I.

Sometimes I'll actually take my comb.

Help work it all the way to the ends.

Everything floats.

There is no up or down for this list will be going over some of the strange and lesser known fax about spending time in outer space.

If you think we were out of our minds toe, leave out some out of this world.

Fax.

Please share them with us in the comments.

Number 10 Cuisine.

Most people have probably heard of Tang, but food eaten in space has come a long way since the early days.

In the early Apollo days, NASA's space food team developed improvements in freeze drying technology.

That same technology makes it possible for food to remain shelf stable at ambient temperatures for long periods of time, while significantly reducing the weight of the food.

Food taken into space used to be packaged in tubes to prevent spillage and for ease of consumption.

But it's a lot more normal these days.

Like most things, weight is a major consideration, since it's more expensive to transport the heavier IT ISS.

But the most important calculation is what things way.

That's because it costs $10,000 for every pound blasted off to the astronauts.

Nutritional value and the food shelf life are also important factors, as it needs to provide everything.

Astronauts need to stay healthy for a long as it can, Often packaged in lightweight, specially sealed containers, space food comes in plenty of variety these days, particularly on the international space station, with hundreds of different dishes to choose from.

Very good number nine body proportions change.

The human body isn't exactly made for being in space, so there are some side effects.

Is spending a lot of time up there to help with this.

Astronauts wear compression cuffs on their thighs to help keep the blood in their lower extremities.

These effects can range from vision problems to muscle deterioration without gravity working on your body, your bones and muscles start to break down to.

In fact, bone density drops by over 1% per month, But one of the most pronounced changes is the shape of the body itself.

Without gravity pulling on it, the spine straightens out, adding toe astronauts heights.

Blood flow also tends to move upward as well, giving space travelers of puffy face ah, wider torso and giving the legs of shrunken appearance.

This extreme makeover space edition is just temporary, however.

Number eight hygiene problems Staying clean is tough enough on Earth, but space adds plenty of its own problems.

Naturally.

Showers and baths air untenable In a zero G environment, we can't take a normal shower because the water doesn't know where, how to find the drain so we don't have a regular shower, so astronauts are forced to use sponges to wash themselves.

Special soaps and shampoos that don't require rinsing are also used to cut down on water.

Faras soap is concerned.

It comes up in pouches like this one.

You need toe add water and then you get a nice, uh liquid soap pouch, which needs to last for about two weeks, and it's a no rains type of socket doesn't make a lot of foam, and it doesn't really need to be rinsed.

Speaking of which, because surface tension keeps liquid close to the skin, they can make do with a small amount of water overall.

Sometimes I'll actually take my comb, help work it all the way to the ends.

They also have to be very careful when shaving or combing their hair, because loose hairs float freely and could be inhaled or get in people's eyes.

Number seven.

Sleeping Difficulties You think getting a good night's sleep is tough?

Try doing it in outer space.

Trying to sleep in space would probably be a nightmare for insomniacs.

It's so bad that they have to actually take bungee cords and strap them down to a wall to make them feel like they're laying on something, because otherwise, the constantly feel like they're falling.

They could never get to sleep.

For starters, the international space station rotates around the Earth multiple times per day, leading to each day, being only around 90 minutes.

This could play havoc on sleeping schedules.

In addition, astronauts must be strapped in so they don't knock into anything while floating, plus the insides of the station are actually quite noisy, as all the machines produce sound, necessitating earplugs or sleeping pills to help put the astronauts out the pills they're taking our reportedly prescribed to treat insomnia and anxiety, or even brain disorders and muscle tension on the ground.

Users of these hypnotic drugs have experienced amnesia and anxiety, even behaviors like sleep driving.

Although there are some benefits, such as a reduction in snoring, the journey toe unconsciousness is an uphill one for many number six space adaptation syndrome.

Motion sickness is what happens when your brain can't reconcile the fact that we're immobile yet in motion on Earth, everything floats.

There is no up or down, and for 70% of first time spacefarers, the initial couple of days in orbit means they will feel ill similarly or rather, opposing Lee astronauts.

Brains have a difficult time adjusting to a lack of gravity and the strange sense of motion while in space.

And we think that that motion sickness occurs because of a difference between what our eyes air seeing and what our inner ear or vestibular system is sensing.

And that disconnect tells the brain that something weird is going on and gives you that sense of nausea or motion sickness.

Space adaptation syndrome occurs usually upon reaching space, with over half of space travelers experiencing illness, vomiting and other discomfort as a result of the sudden change.

Even the specialized training astronauts undergo to withstand nausea isn't enough to eliminate it completely.

We're getting queasy, just thinking about it.

So, yes, astronauts do occasionally get sick and space.

But we have special, uh, barf bags to deal with it.

Number five clothing.

The most famous pieces of clothing astronauts.

Where are the spacesuits used for moving around in the vacuum and getting the entire suit on requires a bit of help.

There's many layers of this.

It makes a little difficult to get in these air incredibly cumbersome and difficult to put on, but offer protection from the conditions of space.

Then there are the flight and entry suits don by astronauts as they ascend or descend in a shuttle or reentry pod while aboard the spacecraft.

However, most astronauts, where pretty typical clothing and so it's very rare that you either get really cold or really, really hot, and so so it's a pretty much a shirt sleeve environment as we refer to it on Earth.

The main difference, though, is that they can't launder clothes due to the aforementioned water considerations and what it is very scarce in space.

We also recycle our water, and we only use it to drink or to wash.

Still, with less physical exertion.

They don't sweat as much, which means they can wear clothes for longer without changing and when they do get too dirty.

Clothes are generally disposed of with other garbage number four toilets.

So everything in space seems more difficult than it is on Earth.

I bet the bathrooms no different.

It's no different.

Curious minds.

Young and old have often wondered.

How do you go to the bathroom in space?

It's actually one of the questions astronauts get the most, probably because, like the famed book says, everybody poops.

Most of the toilets in space function using differential air pressure to dispose of waste.

But you see, it's pretty small, so you have to have pretty good aim.

Can you be ready?

Thio.

Make sure things get let go the right direction.

Liquids are sucked into a tube and eventually jettisoned into space.

Solids, meanwhile, are retained on board until return to Earth.

You take this red tab, you pull it off the rim on.

Depends on how full the container is.

This one's about halfway through.

We do have a a stick.

Then you push it down in there with all its other friends.

Sending poop hurtling through space at high speeds is apparently frowned upon.

We certainly wouldn't want that to be our first contact with an alien world.

Number three.

The Dangers of Flatulence No, we're not kidding.

Farting can actually be hazardous in space.

Farts may smell, but they quickly dissipate in the atmosphere.

Not so in confined spaces like space stations, shuttles or long car rides.

Well, we are in kind of a closed environment, but fortunately we have good filters that take care of things like that.

In space.

Farts linger because there's nowhere for them to go.

And while the odor might be bad, what's worse is the gas is there, made off.

Farts are flammable, and when their gas lingers in the air, the slightest spark could create an explosive situation.

Silent but deadly.

Indeed.

Thankfully, with a controlled diet, astronauts can reduce the amount of certain gasses they produce.

That's one of the few spells you could smell strongly, but it's not exactly a spring garden number two Few deaths in space at 11:40 a.m. This morning space program experience a national tragedy with the explosion of the space shuttle Challenger approximately a minute and a half after launch from here at the Kennedy Space Center.

For a Muchas, the idea of dying in space has ingrained itself in pop culture.

There have been relatively few deaths while in outer space.

As of 2020 there have been 19 deaths related to space flight, 15 of them astronauts and for cosmonauts.

So how is that possible?

Well, with really good technology and understanding of space hazards, the basic necessities food, water and air are either replenished by resupply missions or recycled by the international space stations on board facilities.

Furthermore, most of these deaths have been either during takeoff or reentry that leaves Onley three deaths toe happen while in space itself or above 330,000 ft, which occurred on the Soyuz 11 mission in 1971.

The three cosmonauts were killed after a vent valve defect caused them to asphyxiate in the cabin.

The cause of the cosmonaut's death is a mystery in the intervening moments between signing off on the radio on the recovering team's arrival, something is killed three people.

While fringe theories abound about undocumented space travelers, these three are the only people confirmed to have died in space.

As of this writing, before we get to our topic, here are a few honorable mentions getting used to gravity again.

People who have spent long durations in space often drop things.

ST.

Jocks was carried from the pod, feeling the pull of gravity for the first time in months.

Thence collect everything.

Whatever isn't strapped down gets sucked into them.

No alcohol, not letting people get intoxicated around expensive equipment is a smart move.

NASA has a pretty strict alcohol policy on the S and on the shuttle missions.

Space is dangerous, so being less than sober could cause injury or death.

You can't burp because gravity doesn't keep gas is close to their mouths.

Astronauts can't belch.

Basically, the gas on the liquid don't separate in the stomach in the same way they do on Earth due to the much lower gravity.

So it's much harder to come up with a full burb.

There is no crying in baseball space.

Tears form, but they will not fall.

So just a Ziff.

I started crying, my eyes full of tears, but you can see it just forms a ball on my eye Before we continue.

Number one space affects the brain.

Cosmic radiation is some hair stuff, folks.

Although Earth's magnetic field protects us and those insufficiently close orbit, astronauts are still affected.

More than most, being weightless challenges our internal navigation system.

This can be a problem, for example, if we have to find the nearest escape hatch in an emergency.

The radiation can affect cognitive functions in the brain over prolonged periods and can accelerate the onset of diseases like Alzheimer's that could have serious effects on your brain cells in your hippocampus in your prefrontal cortex.

These are all areas associated with memory, with decision making and literally.

The particles appear to sort of break off pieces of the synapses, and it has the consequences on behavior.

While most astronauts tours aren't long enough for it to be too extreme, planned missions to Mars and other solar bodies like asteroids could prove difficult unless space agencies discover a way to better shield astronauts.

Also, after long missions, scans showed an upward shift of the brain tissue against the top of the skull, as well as a narrowing in the space for the spinal fluid.

After all, we wouldn't want to send them all the way there if their brains aren't up for the tasks they have to perform when they get there.
