What If You Spend Simply 30 Seconds on the Moon And not using a Spacesuit?

published on July 2, 2020

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 video 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

38 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
