st jacques was carried from the pod
feeling the pull of gravity for the
first time
in months welcome to 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 as if i started crying my eye is
full of tears
but you can see it just forms a ball on
my eye sometimes i'll actually take my
comb
to help work it all the way to the ends
everything floats
there is no up or down for this list
we'll be going over some of the strange
and lesser known facts about spending
time in outer space
if you think we were out of our minds to
leave out some out of this world facts
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 is
but the most important calculation is
what things weigh
that's because it costs ten thousand
dollars 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 as
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 to 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 too in fact
bone density drops by over one percent
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 to astronauts
heights
blood flow also tends to move upward as
well giving space travelers a puffy face
a wider torso and giving the legs a
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 are 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 as far as soap is
concerned
it comes up in in pouches like this one
you need to add water
and then you get a nice liquid soap
pouch
which needs to last for about two weeks
and it's a no rains type of soap it
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 and sometimes i'll
actually take my comb
to 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 can
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 they constantly feel
like they're falling they can 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 can 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
are 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 to 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 seventy percent of first time
space bearers
the initial couple of days in orbit
means they will feel ill
similarly or rather opposingly
astronauts brains have a difficult time
adjusting to a lack of gravity
and the strain sense of motion while in
space and we think that that motion
sickness occurs
because of a difference between what our
eyes are seeing and what our inner ear
our 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 in space
but we have special
barf bags to deal with it number five
clothing the most famous pieces of
clothing astronauts wear 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 so it makes
a little difficult to get in
these are incredibly cumbersome and
difficult to put on but offer protection
from the conditions of space
then there are the flight and entry
suits done by astronauts as they ascend
or descend in a shuttle or re-entry pod
while aboard the spacecraft however most
astronauts wear pretty typical clothing
and so it's very rare that you either
get really cold or
really really hot and so so it's 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 water 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 bathroom's 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
and you'll be ready to 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 returned to earth
you take this red tab you pull it off
the rim and depends on how full the
container is
this one's about halfway through we do
have a stick
and you've 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 gases they're made of
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 gases they produce
that's one of the few smells you can
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
experienced 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 as much as 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 the astronauts and four 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 station's onboard
facilities
furthermore most of these deaths have
been either during takeoff or re-entry
that leaves only three deaths to happen
while in space itself
or above 330 000 feet 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 cosmonauts death is a
mystery
in the intervening moments between
signing off on the radio
and the recovering team's arrival
something has 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 top pick here are a
few honorable mentions
getting used to gravity again people
who've spent long durations in space
often drop things st jacques was carried
from the pod feeling the pull of gravity
for the first time
in months vents 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 iss 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 gases close to their mouths
astronauts can't belch basically the the
gas
and the liquid don't separate in the
stomach uh in the same way they do on
earth due to the much lower gravity
so uh it's much harder to come up with a
full burp there is no crying in baseball
uh
space tears form but they will not fall
so
just as if i started crying my eye is
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 in sufficiently 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 and 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 a 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 do you agree with
