Let’s chat about Space Fashion, shall we?
The bright
orange color astronauts wear to go out for launch is called International Orange,
and it’s the same shade as the paint that coats Tokyo Tower in Japan, and the
Golden Gate Bridge in San Francisco. However, once astronauts are in space, they swap orange
for snow-white evening wear. (It’s always evening in
space.)So what gives with the different colors? Well, there are actually two
main types of spacesuits. The first one is the Advanced Crew Escape Suit, aka
the "orange suit," aka the "pumpkin suit." Trick or treat! Astronauts
wear this full-pressure suit during "lift-off". These spacesuits are
crucial for those who are heading for super high altitudes. There, the pressure
is so low that people can't survive without a special protective suit... Anyway,
the orange suit is equipped with different stuff that can help an astronaut to
survive if something goes wrong during the launch or landing of the spaceship. For
example, a usual "pumpkin suit" is stocked with flares, survival
gear, medications, a radio, and a parachute. And a bunch of candy in case the
costumed kiddie s come to the house. Not really. Well okay, I get it,
astronauts wouldn't live through the process of leaving Earth without the
orange suit. But still, why this color? The main reason for picking orange is
that this hue is one of the most visible for search and rescue, including sea
rescue. Makes sense. Alright, well how about the white, bulky spacesuits? Ah,
these are EVA (which stands for Extra-Vehicular Activities) suits. And their purpose
is totally different from that of the orange suits. Astronauts wear EVA suits
when they go on a spacewalk! Such an outfit can protect them from the
unfriendly conditions of outer space, what with its extreme temperatures and
near-vacuum! Besides, the white suit can prevent small debris from hurting
space-travelers. You might have noticed that EVA suits are much bulkier than
the orange ones. That's because they contain numerous layers of insulation and
heavy protective fabric. On top of that, they contain breathable air, drinkable
water, and temperature controls. Also, every time an astronaut goes on a
spacewalk, they use a tether that ties them to the space station. However, in
case the tether tears, the EVA suit has a backup system. This system includes
small jet thrusters that can be controlled from the station with the help of a
joystick. As for the color, the white hue reflects the heat of the sun better
than other colors. As a result, astronauts don't get too hot. What's more, the
white color is best when it comes to spotting a tiny dot of an astronaut against
the vast expanse of black, black space. One curious detail: while white
spacesuits protect astronauts from getting too hot, they can't prevent them
from getting too cold. And that's when the spacemen's gloves come into play! Yep,
they have embedded heaters that keep astronauts' fingers cozy and functioning.
And speaking of cool, how about some more cool facts about astronauts that’ll
give you a sneak peek at their highly unusual lives! - While sleeping,
astronauts must have exceptionally good airflow around them. Otherwise, the
carbon dioxide they exhale can form a bubble around their heads, and they’ll
become oxygen-deprived. - When one astronaut threw a boomerang inside the
International Space Station, it returned to him. So, just remember that as long
as there’s some air which provides the necessary forces, even weightlessness
won't prevent you from having a bit of fun. - Astronauts have to get rid of
their clothes after each use. See for yourself: to bring a mere 1 pound of
laundry to the International Space Station costs more than $10,000. So, it
costs less to throw the clothing away when it gets dirty than to waste water on
washing it. - Skylab was the first American space station that operated for
about half a year from May 1973 to February 1974. Its interior was pretty big,
and astronauts sometimes got "stuck" in the middle. From there,
they’d have to wait for the currents of air to blow them closer to a wall or
try to "swim" back through the air. - Months after coming back from
long missions in space, astronauts still tend to let go of things while they’re
still in mid-air. They’ve gotten so accustomed to everything floating – they
get a shock when the objects simply crash to the floor. - There was an
astronaut who’d been waiting for a whopping 19 years before he finally flew to
space. The thing is that the mission he’d been selected to go on got canceled. Then,
he remained a backup for other astronauts. Only in 1985 did the persistent
astronaut managed to fly on the space shuttle. - All American astronauts have
to learn Russian to be able to run the International Space Station using
Russian-language manuals if there’s no alternative. - There’s a specially
trained person who smells every single thing that astronauts take with them
into space. It's done to protect them from unpleasant or toxic odors. The thing
is that you can't really air the room out in space if you don't like how it smells
inside. That's why NASA is extremely careful about what kind of odors are
allowed to pass through. - During space adaptation, 50% to 75% of astronauts
have highly unpleasant syndromes, such as vertigo, headaches, nausea, and
overall tiredness. Well, that doesn’t sound like fun! Luckily, everything goes
back to normal within 72 hours. - When astronauts are in space, they often see
random flashes of light - and it's not hallucinations! Cosmic rays that hit the
optic nerve create this effect. You don't see similar flashes here on Earth,
because the magnetosphere doesn't let cosmic rays reach you. And that’s a good
thing. - If an astronaut needs to scratch their nose while wearing the EVA
suit, there’s a patch of Velcro inside the helmet. I was always wondering about
that! - Before going to space, astronauts have underwater training, which is
supposed to simulate zero gravity. But in fact, it has nothing in common with
being in outer space. So, the main purpose of underwater training is to see
how future astronauts can deal with extreme environments. - If you've always
dreamed of growing a bit taller, you should probably go to space! Due to the
lack of gravity, astronauts grow, on average, 2 inches taller during their
mission. But, they shrink back several months after they return to Earth. -
Obviously, if someone gets injured on the space station, they can't be rushed
to a hospital right away. That's why each astronaut is extensively trained so
that they can deal with medical emergencies. - Before flying to space,
potential astronauts have to get through incredibly tough competition. According
to NASA, they accept only 8 applicants out of 6,000! On top of that, the
selection process takes around 18 months! - When an astronaut returns from a
long stay on the ISS, they feel incredibly clumsy. After being used to the lack
of gravity in space, it’s difficult to adapt to the necessity of climbing steps
or going around furniture. - The lack of gravity also makes sneezing inside a
spacesuit a serious problem. If they absolutely have to sneeze, astronauts bend
their heads downward and sneeze into their chest. Otherwise, their visors would
have to be equipped with windshield wipers! And that snot very pleasant! -
Astronauts have been replacing bread with flour tortillas since the mid-80s. The
thing is that crumby foods are understandably not allowed on the space station
because stray crumbs can damage the equipment. Tortillas, on the other hand,
don't present such a risk. Besides, they instantly became very popular with the
astronauts. They also fly very well in a weightless environment. - If an
astronaut cries in space, tears don't flow down their faces. Instead, they
gather into thick blobs of liquid around their eyes because the water surface tension
holds tears together. - Surprisingly, when coming back after a mission away
from the Earth, astronauts still have to pass through customs. For example,
when Apollo 11 returned from the Moon, the spacemen had to declare the moon
dust, moon rocks, and other samples they’d collected on their trip to a foreign
land. I mean really far away. - Astronauts who forget to attach themselves to
something when they sleep can easily float away and bump into a hard surface. That's
why they usually rest in sleeping bags in a small crew cabin. - To shower
without gravity isn't an easy feat. Thus, astronauts take a shower in an
enclosed cylinder which keeps the water from floating away. They use a no-rinse
shampoo, spray themselves with water to rinse off the soap, and finally, use a
vacuum hose that sucks up all the water from their bodies. - The ISS orbits
our planet at a very high speed. I mean, it only takes 92 minutes to make a
full circle! That's why astronauts see a sunrise and a sunset every 45 minutes,
which totals 15-16 sunsets and sunrises each day. And if you want to see the
space station fly over your house during the morning or evening hours, check

a heads up with the exact times when you can run out and wave to the astronauts
as they fly overhead.
