What If You Spend Just 30 Seconds on the Moon Without a Spacesuit?

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 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 if you liked the video give it a thumbs up don't forget to subscribe to the channel click on the
