The moon is the only space object
visited by man on July 20th 1969. the
Apollo 11 spacecraft landed on its
surface Neil Armstrong became the first
man who walked on the moon together with
Buzz Aldrin. they spent about two and a
half hours on the Earth's natural
satellite preparation for the flight
took several years and all of the
astronauts equipment weighed more than
80 kilograms or about a hundred and
seventy-six pounds. so ,what have you
found yourself on the moon without all
this protective equipment or a
protective suit. what a person be able to
survive on the moon for at least 30
seconds. by the way do you know how many
people have visited the moon you'll
learn the correct answer at the end of
the post.so let's imagine that you're
on the moon you have moon dust under
your feet and a black sky with stars
overhead but you have no time to admire
the scenery.
unfortunately ,there's no air for you to
breathe the moon has practically no
atmosphere compared to Earth's which is
10 trillion or 10 to 13th power times.
denser the moon's gas content is
considered to be a vacuum. in fact the
density of the atmosphere of the moon
can be compared with the density of the
uppermost layers of the Earth's
atmosphere. where the ISS the
International Space Station is located
but there is good news in such
conditions.
you won't die instantly you have about
15 seconds before you pass out from
hypoxia this is how much time your body
will have to use the remaining oxygen in
your blood to sustain brain function but
a lack of air is far from our only
concern you've probably seen memes of
the blobfish.
which is called the saddest creature on
earth.
fact it's a drop in pressure that makes
it so sad this fish lives at great
depths and there it has a very normal
look but when it's caught
due to the large difference in pressure.
it inflates on the moon you risk
becoming a sad blob fish since there's
practically no atmosphere. there the
pressure is extremely low on earth a
column of air with a mass of about 15 to
20 tons presses the entire surface of an
adult's body.
however we don't notice.
this firstly the air pillar presses
evenly from all sides and secondly
there's also air inside of our bodies
and the internal pressure is equal to
the atmosphere. but due to low pressure
on the moon nitrogen dissolved in the
blood and tissues will be released in
the form of bubbles in your blood your
body starting with your arms and legs
will swell like a balloon but you won't
burst the elasticity of your skin will
protect you from tearing. but don't try
to hold your breath and such a low
pressure you could face the same problem
as divers .when rising too fast to the
surface your lungs could burst a better
idea on the contrary is to exhale.
moreover under such conditions water
will boil regardless of temperature this
means that the liquid in open areas. skin
eyes will evaporate you'll feel how this
saliva boils on your tongue.
but the
blood will remain liquid the walls of
your vessels will protect it from
boiling we can't exactly call the
temperature on the moon comfortable
during the day the surface warms up to
127 degrees Celsius. that's 260
Fahrenheit and at night the temperature
can drop to minus 173 degrees Celsius
that's minus 279 Fahrenheit.
moreover a day on the moon is equivalent
to 29 earth days spending 14 and 1/2
Earth days in life and the same in
darkness .therefore like Apollo 11 it's
better to choose dawn for a visit to the
moon when the surface is not so cold. but
hasn't had time to warm up too much .but
even if you find yourself on the moon at
night. you won't freeze instantly there
are three types of heat transfer
conduction convection and radiation in
the vacuum of space there's only one
kind thermal radiation. so you'll lose
heat very slowly. but you're not just in
space you're standing on the surface of
the Moon .which means that there's
another kind of heat transfer in
addition to thermal radiation conduction.
but the surface of the Moon doesn't
conduct heat very well .
so you won't turn
into ice at least not in 30 seconds.if
you find yourself on the moon in the
afternoon.then within a few seconds
instead of panic you'll get burned by
solar radiation on earth. the ozone layer
protects us from the dangerous
ultraviolet radiation of the Sun and on
the moon. you won't have such protection.
in addition it will be unbearable to
stand on the hot surface.
also the natural satellite of the earth
has a very weak magnetic field. this
means that once on the moon you'll be
attacked by streams of solar and
galactic cosmic rays. according to
scientists the approximate level of
radiation on the moon throughout the
year ranges from 100 to 380 millisievert.
you would receive about 1 millisievert
by getting 3 chest x-rays that is if you
stay on the moon for a year you'd
receive the same dose of radiation as if
you would receive from 300 to 1140
x-rays in the future. you would face big
health problems but not in those 30
seconds if only your stay on earth
satellite doesn't coincide with the next
cycle of solar activity. which happens
every 11 years during that time flares
on the Sun emit a particularly large
number of x-rays and gamma rays in this
situation.
you're very likely to die
instantly another trouble that awaits.
you on the moon is dust called regolith
this is where Neil Armstrong left an
imprint of his boot. since there's no
wind on the moon it has survived to this
day and if you had more than 30 seconds
you could find it true you definitely
need a spacesuit without one moon dust
carries mortal danger for you have you
noticed the huge number of craters on
the moon
these are traces of meteorites falling
the active bombardment of the moon ended
3.8 7 billion years ago nevertheless
meteorites still fall on its surface
sometimes they are tiny and sometimes
they are incredibly huge for example in
2014.
Spanish astronomers recorded the
collision of a meteorite weighing more
than 400 kilograms or 882 pounds if you
find yourself near the place of the fall
of such a giant then you're 30 seconds
on the moon will expire much earlier
when meteorites fall.
regolith forms as a result of crushing
of lunar rocks under vacuum. its
particles are very small ranging in size
from point zero three to one millimeter
that's point zero zero one two point
zero four inches however they're very
sharp and can easily damage your lungs.
moon dust is constantly bombarded by
solar wind particles which is why it
acquires a positive electric charge
therefore it seems to rise above the
surface of the Moon
so regolith will cause you. I irritate
and sinusitis so you're thirty seconds
on the moon have expired these were not
the most pleasant seconds in your life
but the good news is that you're still
alive but what if you stay there longer
without a spacesuit in the end the lack
of air can kill you.
oxygen starvation will occur and then
damage to your brain cells but if after
90 seconds of being on the moon you're
able to return to livable conditions
then there is a high probability you
will survive but if you want to take the
same long walk on the moon as the
American astronauts then you still need
reliable protection NASA just introduced
a new lunar spacesuit. in which the
Americans hope to return to the moon
it weighs 91 kilograms or about 200
pounds but since the gravity of the Moon
is six times weaker than on earth the
developers are sure that it will be
comfortable to move in astronauts will
not have to jump on the surface of the
Moon like their predecessors.
they can
literally walk the new suit will also
protect against moon dust and radiation
it's designed for moon walks lasting up
to eight hours the Americans hope to fly
in these protective suits to the moon by
the Year 2024 and in 2028 the first base
should be built on the moon.
NASA's new lunar program is called the
Artemis program and finally the answer
to the question. how many people have
visited the Moon in the period from 1969
to 1972 under the Apollo program six
flights were performed with a landing on
the moon twelve people visited its
surface the longest walk on the moon was
made by Gene Cernan and Harrison Schmitt
during the last Apollo flight it lasted
seven hours and 36 minutes and astronaut
Alan Shepard was even able to play golf
there as you can see despite the harsh
conditions the moon remains the most
hospitable object in the solar system
and perhaps walks on Earth's satellite
in the near future will become a reality.
