Subbed!!!
How about get off the couch /pc for FREE?
Scishow is fabulous enough for me.
Right?
I see what you did there
1:39 I'm pretty sure that blue spiky stuff on the wall is extreme soundproofing and I can't be the only one who finds its location hilarious.
The year: 2097. Humans have explored the solar system and colonized mars. The "life finds a way" reference still exists, Jeff Goldblum is still alive.
And still being happy being Jeff Goldblum.
Won’t happen by then, not even eletric cars will be the new thing by then, sorry to say it
That sounds nice but many countries are intent on destroying the world just so they can have more power o er smaller countries and take more resources instead of working together. Who really cares which country is more powerful? That does nothing to improve the eorld.
@@tacobell5928 You're correct of course, especially the way Humanity is going lately, the amount science deniers, idiots and Karens coming out of the woodwork I'd be surprised if humanity itself even exists that far into the future, unless we stand up to the derp our planet and species is doomed! 😱
Imagine being a fuzzy worm in space then getting touched with a wet cloth then exploding.
. . . Huh! I DREAM of being a wet cloth. . . you can keep the bit about exploding though. . . 💣💥
Bless the maker and his water
I'm awarding you 10 trillion internet points for this blessed comment
Do the astronauts use UV light to kill bacteria? At the hospital, whenever a terminal clean is performed after an MDRO patient discharges, a big UV lamp is used after standard cleaning protocols. We call it the bug zapper.
Perhaps the radiation up there is much stronger than a safe UV light would? So the organisms growing probably are ones that have extra resistance to radiation.
@@ImTHECarlos98 Radiation exposure on the ground is on the order of a few millisieverts per year. On the ISS, it's around a hundred millisieverts per year. Sounds significant, until you figure how great a dosage UV lamps put out. One Sievert can be defined as one joule of ionizing energy received per kilogram of body mass. A reasonably strong UV lamp installed in an air duct would give an irradiance per area of somewhere on the order of tens of milliwatts per square centimeter, if not greater. Assuming that one square centimeter is covered by 0.1 grams of bacteria (really grossly high value), this gives a rate of 100mW/gram. Converting this to joules per mass, this is 100J/kg per second. That's a a hundred Sieverts per second. For reference, ten Sieverts is guaranteed to be fatal to humans. This is ten times that, per second. This level of radiation would be like standing in the maw of Chernobyl Nuclear Power Plant's Reactor 4 just hours, maybe minutes, after it exploded. Now, bacteria and other small organism *are* more radiation-hardy than humans, but at this scale, it doesn't really matter; survival time is measured in minutes at best.
Those lamps are UVC which is not great for humans.
Important people to make an astronaught team : compitent leader, software engineer, mechanical specailist and your high school janitor
easy solution, is to just open the windows, and air them out from time to time.
😂
In space, no one can hear you clean
I've never considered getting sick in space. That would suck!
I'd be tempted to space myself to get relief from sinus pressure.
Yeah. Sneezing would catapult you backwards.
@@lonestarr1490 Only slightly. Your mass is high enough that inertia alone would nullify most of the force. So you'd barely move.
Microbiota? Different than microbiome?
“Microbiome” can refer to a group of microorganisms in addition to the micro-environment they inhabit, which forms specific ecological niches. The term Microbiota specifically refers to only the communities of microorganisms themselves. Although the term Microbiome is often used interchangeably with Microbiota.
@@ninboy01 thanks you internet dude:)
It's pretty incredible the lengths these little guys will go to just to find a way on the space station. I imagine if we let them go long enough they would eventually eat the whole thing and adapt to living in the debris field that litters low earth orbit. This is a problem without a solution, I think. Except maybe a bioship, but that's outside of our ability for the time being
Breaking down the rubber seals, you say? So, the Andromeda Strain was a prophecy, then? Good to know.
Imagine getting bored, or even annoyed that you have to clean in micro gravity. Floating around at all angles, spinning, and zooming from one side to the other.. while muttering that it's your day to do the dusting. I can't. It MUST happen.. it's a chore, right? But still... I just can't imagine doing anything but smiling while doing it up there.
I’d be mad. You have to dust EVERYTHING because nowhere is floor.
You also shouldn't leave lobster in the fridge for too long.
What about using controlled ultraviolet for surface disinfection in addition to disinfectant wipes which can't be used everywhere.
Exactly what I was thinking.
Its now becoming somewhat more common thanks to COVID but I've been using UV as a cleaner for my business for nearly 10 years.
Edit: Apparently, parts of the UVC wavelength don't produce ozone. So, the stuff below may not apply depending on the type of light source used.
The UV-C light that is used for disinfection also generates ozone when it strikes oxygen molecules in the air. It is toxic to both microbes and humans so you'll usually want some good ventilation to keep ozone from accumulating indoors. The UV disinfection box I'm using uses the ozone generated to kill microbes where the light can't get to them directly. Leave it on for 30 mins and you can smell the ozone when the box is opened.
Unfortunately, It would probably be too much of a breathing hazard on the ISS.
Good question! I was on the team that was tasked with disinfecting the bellows of the air pump used in the ISS. The bellows began to form a biofilm, so we designed a system of UVC LEDs to disinfect the non-uniform surface of the bellows.
@@Hafiere I was thinking ozone would be good; it has a half-life, so you don't necessarily need ventilation, and the ISS presumably has air locks, so you wouldn't have to be in the same room as the ozone. It does corrode exposed metal though.
@@Hafiere As far as I know, which could be incorrect, the wavelength of UVC light used for disinfection does not produce Ozone. The peak wavelength we used on the ISS was 280nm; we used a bandpass of +/-25nm. To create Ozone you need < 240nm.
maybe they should work on how to civilize the microba, and provide wood surface for microbe to chill into and die graduate (in compare to plastic, cutting boards material experiment)
Thank you
3:20 Imagine we could be using these new microbes on earth for recycling tires or mining metals!
Bringing a bacteria like that to earth could be a disaster . 😄🤟
Especially the rock/metal eating ones.
I wonder how we started calling germs "bugs" when they're so very different from insect bugs
Would be very interesting to see a video on what happens if someone passed away while on the ISS, I've not seen what the procedure would be
To clarify, I mean natural death on board rather than exposure to space, there are many videos on that but nothing on the procedure for death, as in do they bring the body home or jettison it into space, I can't imagine a decomposing corpse in a sealed environment being a good idea
There must be some plan for that if someone is up there for a long period
u tel it not to come back
Journey to the Microcosmos: Orbital Eddition!
What a beautiful shift.
This is bringing up War of The Worlds visions.
I never thought about the complications of microbe colonies running rampant on like a stasis or intergenerational starship
Are the experiements they do on the ISS public? Actually pretty interested in how bacteria and fungi be have in zero G
my mind: "Oh, it's like in that film, Gattaca"
Open the airlock & whoosh!
I wonder how well a UV light ball would work, like toss one in the module as you leave and it just floats around and glows UV. Maybe it could have a little vibration motor that activates occasionally so it continuously moves around. The ball could be whatever the best size is so that it doesn’t get stuck anywhere. Maybe it could be inflatable. Just an idea
Why not just sunlight
@@saynotop2w can they have like straight sunlight entering the station or would that like blind everyone? Not sure how that works in space.
Pretty sure I've discovered some new species in the McDonald's ice machine!
so would time with your crew before be a worthy excuse to build. immunity in my anime
There were blobs growing on the MIR station.
4:01 ive seen comments on videos on this subject talking about using microbes to fight microbes, since eventually theyll become resistant to the sanitization wipes, so "natural" "disinfectants" may have better effects in the long term ((affects? i always mix those up))
Effect is End result Affect is Action
@@Astrochellie ty ty
Okay if no one else is gonna say it?
I love you Hank.
Any studies of dust mites on the ISS?
I'm tempted to suggest ozone, but it also corrodes exposed metal, so maybe not.
I imagined they could just open the airlocks and let the vacuum of space do the rest :D
Ask the bacteria to leave
How are bacteria in/on our bodies changed by being in orbit?
Bacteria is an integral part of human life.
I imagine they make use of UV light as well.
Very Mass Effect Quarian vibe
Just grab 'em and put em outside bruh
Thanks. Eating away the plastic & rubber seals? Andromeda strain. Yikes! tavi.
A giant leap for those microbes.
my brother in law told me they have gold-eating bacteria up there, still not sure if that's true (how do they eat something that's chemically inactive?)
Leave it out in space in direct sunlight.
Obviously through the bio filters.
Seems like they could seal off sections and vent them for a couple days.
Wouldn't need to vent. Just use ozone generated from electricity and the onboard oxygen.
How about UV light to kill germs?
I though this was going to be about using gamma lasers to blast bacteria into oblivion.
Vent to space
Life tries to find a way
Humans: I am sorry we don't do that here
My first thought would be to remove humans, replace them with robots. Saves me a lot of money I can use on actual space exploration, beyond low earth orbit.
Lysol
Sorry, what? What's Funjeye? Do you also say funjus for the singular?
microbes on surfaces? dont they wear clothes until it's crunchy af and then burn them?
Space Poggers.
Very carefully
i hope spacex in particular considers this when sending cargo, crew, and other variants of the starship to mars in 2024 and later
I can virtually guarantee you SpaceX isn't going to be the first people on Mars, but govts. By the time they get there'll be strict rules to follow. Bureaucracy has infinite reach. :)
Your video interesting
How awful would it be to accidentally spread microbes to places like mars then we discover large bacteria and fungus colonies thriving later when we return?
We already did. Viking probe, step forward!
Sterility standards weren't all there at the time compared to now! Guaranteed it had some nano stowaways on the journey; nobody's THAT anal with space sterility, surely? Besides, our dysfunctional boi Elon has defo added to the mix with Cubesats aplenty, and plenty more due. Space biohazards! Can't wait for a Michael Crighton novel to unfold ( Andromeda Strain lol !) 😈☣⚠️
🚀🌙 "THE WRONG STUFF......" 🛰️🪐
#1: 👩🚀✨ STOP SNEEZING IN YOUR SPACE HELMET!!! 🗣️🦠🤧
#2: 🚽🧻 Avoid explosive diarrhea in zero-gee 💩......🤭🤢🤮
😂🤣 All of this reminds me of the story of Col. Hank Snart, who terrorized his entire crew by chewing tobacco in zero gravity
🤣😂😅
~~Live Long & Prosper 🖖🏻👽
🌌🔭
P.S.
In space, no one can hear you fart......
🍑💨
Come on guys, the best way to get rid of bugs is what my mom always said, Just open up the doors and windows and air the place out.....
Cells devide faster in lower gravity .
This good Europa and Mars but unfortunately for rest of the Galaxy most planet have heavier gravity then earth
You use a vacuum!
Open the hatch?
Space swiffer
Ok. So you’re essentially… let’s say… “immuno-compromised” if you do any kind of long term space travel. So it makes sense why so many futuristic depictions of space travel include sleek super clean interiors
Perhaps there’s health care in those universes. They wear masks when there’s a plague. Stuff like that
is this guy on speed?
What I'd like to know is how do you get rid of Russian satellite shrapnel in space stations.
It’s not a problem. It’s just passing through.
Balance it out with American Space Debris! Oh look, there's the old ISS toilet! And bits of Mikey's lost comms sattelite! And an old reactor!(👁👁) 👽
@@robinhodgkinson it's a Problem when it passes through you. 7 miles every second. Now work out how much kevlar you need to survive. Then again,stay home.
@@davidripley2916it’s just passing through… the space station. I didn’t think it was that subtle. : )
@@robinhodgkinson It's late ; so am I 😖
How Do You Get Rid of Bacteria in Space Stations
? ...with FIRE!!!
You should ask them how are they going to clean up their space 🚀 when they come back from space before get into the atmosphere 🤔 😏 🙄 🤣 😅
Don't astronauts use lysol spray on the ISS?
So not my initial idea of spraying everything with bleach while everyone is in a eva suit?
UV light
You dont! The bacteria gets rid of you!
Covering metal surfaces with silver doesn't just look nice...
SPACE IS NOT A VACUUM
Edit: Even if astronauts use vacuum cleaners!:-)
Prometheus
Being in space is super NASTY.
BY NR
🤔Just don't go to space and you dont have to work about "bacteria in space"
Open the door?
imagine all the new microbes we will find when we privatize space...yum
#CoolStoryBro, but can you now teach us how to do that to a play station instead? Or at least the controllers 😂
Stop using people all together use robotic arms and make the space stations the robotic cleansing approach
Sterilizing the stations combination of prsherized sea salts and a dry ice vapor mist by robotic interfaces with arms wet cleaner robotics and the elements like sunlight or laser to mimic it to dry them with lemon and lime and vinegar solutions acid it having a inviermentI wet station bypassing the use of humans all together and use robotic AVITAR's as drones man like drones the drones wouldn't have to bee bipedal at all the could be just the torsos and arms and head of said fixtures that putrid out on a jointed arm that comes out of a wall unit or injuction having full assembly and assessment of the spacecstation and little drones
This sounds like a question on the British panel show, QI.
Life as an astronaut is growing increasingly unappealing and unglamorous to my eyes.
It's like going to a camping trip with very basic facilities and you have to stay inside anyway because the outside is going to kill you.
Thanks, but no thanks.
Incas be like: Duh.
Rust blocks many forms of radiation
Not Gamma though.😈💥😯
Blow up one of your own satellites. Gets rid of bacteria, dust, astronauts, cosmonauts...
Fascinating topic, but not actually addressed in the video. Just the existing and possible sources of such in space.
No discussions on their remediation.
SciShow: It's hard to disinfect space stations.
Russian military: Hold my vodka.
With a title like that I'll always insta click
One is caught up playing the impassioned protagonist in one’s Subjective Narrative of Self 🎈
space COVID 🤔
Why not just vent it to space? Do that once a year will kill anything in there.
So, should we be concerned about Musk and Bezos personally infecting our planet?
If Russia try to test an anti-satellite weapon again, we might not have the International Space Station.
