I wonder if the human race would ever considered space travel and colonizing planets possible if we didn't have a moon just sitting out there within our grasp?
If we didn’t have a moon, I don’t think you and I would be sitting here as we are now. It has contributed so much to our life here with the way it has went hand in hand with our own planet with lunar tides, slowing down the spinning (which basically curbs strong winds and storms along with giving us a vital amount of daily sunlight for photosynthesis compared to the estimated 6hr days we’d have without it), likely more asteroid impacts on Earth with no moon to pull them to its gravitational field, our own gravitational bubble would be nonexistent, plate tectonics would basically be null (which has helped shape our terrain), and even precious metals that we use in our every day life even rely on our moon.
It’s but a small rock in the sky to gaze at to many, but if it wasn’t there, we couldn’t even be able to sit and fantasize or imagine how life would be without it because life would be significantly altered intelligence-wise.
@@TwoBs that's not what he means
@@jesuschristlovingyou Still answers the question, what's your point?
@@TwoBs That's dangerously close to invoking the anthropic principle. The fact is we don't know what the requirements are for life and it may have still been possible for complex life to develop even absent a large moon.
@@ratemisia this comment is below me.
I remember reading an SF novel describing a mission to the Moon's pole, and those electric charges where a BIG problem for the explorers. They had a problem with the visor of their suits not getting the same charge as the dust around them and getting covered with dust, blinding them. It got worse when they realized that the dusting pads they have would generate a positive charge on the visor.
whats the novel called?

We've conquered Earth and destroyed it. We'll try to conquer space and get crushed.
@@lorenzoblum868 destroyed it??? You're still here and breathing aren't you. You still have food to eat and apparently an internet to make your stupid comment with. But yeah destroyed planet and all yeah I get it... Go virtue signal somewhere else. Maybe a bar you might get laid for once who knows.
I also understood that a massive issue is the physical properties of lunar regolith itself. At the microscopic level it has very sharp and tiny edges, that wore into the Apollo suits...when examined upon return to Earth, it was calculated that that suit technology was beginning to fail on the longer missions, and that a suits usefulness was to be counted in days, not even weeks.
This is one reason I am very sceptical about a Mars colony, or even mission, in our lifetimes.
I think, and I might be wrong it was a while ago, they’re looking at a way to counter that by giving the suits surfaces negative electrical charge relative to the regolith to reduce the effect.
Moon is way more hostile than Mars. Mars has an atmosphere and lower extremes in temperature.
it will take another century before we have humans on mars
In scifi movies when the heros spaceship breaks down they need to find a source of immense energy to repower their ship. Usually a lightning bolt, or some other natural phenomenon. It would be really cool to see them use the electrical energy from a solar wind crater!
I was thinking the same, it’s a high voltage battery waiting to be tapped. All they need is a faraday cage, like the ones Tesla built. Plus it’s the least hot area, and where the water is.
I never knew that electricity could be such a problem regarding returning to the Moon and going beyond.
Thanks you Astrum !
It's not
Shocking, ain't it.
I'll see myself out
It’s almost like we’re living in an… Electric Universe!
The shock to the astronaut is relatively easy to solve by adding conductive materials into the suit, allowing it to act like a faraday cage. More of a problem for the sensitive electronics that assist the astronauts, and any vehicles they are in. In fact, if done properly this phenomenon could be used to recharge batteries.

Great video. Now in August 2023, India's Chandrayaan-3 has soft landed successfully on Moon's south pole , becoming first country to land on south pole 🎉🎉. It would provide polar region data to NASA to support incoming Artemis missions to moon
China was there first

India did it crazy.
I would think an insulator is the very last thing your want in a spacesuit to combat electrostatic discharge.
In fact, you want it to be conductive so that it discharges any field the astronaut wanders into. Basically, you're making them a walking faraday cage/lightning conductor.
👍Some people don't understand electricity. Faraday cage = GOOD. Let channels EEVBlog or Electroboom, put their 2 cents on this video.
Good call..) I think it would be very useful to high-altitude nuke a crater to melt the regolith and create a dust free environment for rocket landing and habitation.. doesn't have to be nuclear, could be chemical.. some sort of space thermite could work.. or maybe some acid that eats it up and lets it form something solid to land on.. Feel like Nasa is still living in it's space-port cardboard box and not letting anybody else in..)
You don't want it to be purely conductive, though. You do want electricity to discharge through the suit but you still need to prevent it from discharging through the wearer. As such, an outer conductive layer over an insulated inner layer would be closer to an ideal setup.
Yeah, a layer of a few atoms of Aluminium or Gold would help for the shock hazard, but would it also help against the Regolith sticking to any surface?
To act against electrostatic when weighing substances in the lab, earlier we used to dip the spatulas in Uranium solution. But maybe it's not such a perfect idea to dip astronauts in it ;)
Well there would need to be some way for any built up charge to be discharged without discharging through the person in the suit. Some sort of material between the wearer and whatever discharge system is implemented is definitely necessary.
What I find most appealing of the low temperatures on the moon, is that superconductors can be maintained without liquid helium or nitrogen.
Frictionless machinery and ultra efficient electronics.
The machines would warm up, though.
@@uku4171 maybe it would be cold enough around the superconductors and machines that passive cooling them with huge radiators would be sufficient.
@@ooooneeee Even if it required liquid coolant, youd just have a big tank of some pressurized gas with a small pump and a line running through the machine. Like a liquid cooled PC, the tank would remain at a constant temperature without refrigeration. Not sure if it could stay cold enough for super conducting though, and the added weight on a shuttle of giant tanks of coolant would be expensive to launch
@@ooooneeee maybe
@@uku4171 I’m sure there are work arounds. And with superconduction, the heat is greatly reduced. Electronics heat up because the system isn’t efficient. Electrons bounce around and create heat, as well as mechanical friction.
What I picture is an AC power generator where the superconductors use quantum levitation so they never physically touch anything as they spin through the coils to generate the electricity. If all the circuits were also superconductive, the heat generation should be near zero. In say a no gravity environment (not the moon obviously), they should spin for a real long time with minimal energy put into the system to maintain the spin of the generator. At least on paper...
The charged particles at the crater rim - This pretty much fully explains Transient Lunar Phenomenon (the flashes of light seen through telescopes etc but had yet to be fully explained). Fascinating stuff.
That would make sense.
Now if we can just figure out where the atmosphere that was found came from.
Thank you! That was a very interesting presentation of the electrical technical challenges to lunar exploration that I have never heard of before.

It's amazing that we're not only able to detect these hazards in extraterrestrial climes without ever coming into contact with them, but are able to devise finely-tuned countermeasures that are tested by accurate simulations that can be produced on Earth.
Cool story bro.
@@kurtpena5462 Humans can detect change and can make great discoveries, unfortunately the best bot sometimes, is a human bot.
You are actually, lol I don't watch many movies and I recognize the importance of robotics, but there's also something to be gained, such as any mis-haps being in orbit or the lunar surface, can be easier addressed. Plus if there's anything new or not in the computer, it may not know what to think of it, humans do need breaks, but while robotics are by idea, eternal, at least in a sense, people are good at going with the punches. I think sending both would be the best route, especially since something might break down, or may require some cleaning. So no movie for me! :D
cant wait for climate catastrophe counter measures ...oh wait were accelerating the wrong way !
@@kurtpena5462 I just think that if we're going to the moon, Best to have both during the mission, we definitely don't have the means to send off anything more than Rovers without any issues, we can however have a great team that's dedicated for the mission, I mean, no matter what we think, NASA does NASA stuff, but yee, I see both sides, and can definitely see where you are coming from, but I also agree, if they want to go back, bring some people there to help make things go smoothly, have a great and safe day!
India just landed there what is the problem, you were wrong
ISRO on its way.
Would it be a possibility to stick giant metal rods into the ground around these conductive areas to capture these ions and generate some sort of power for any human settlement?
Could we have a video about capturing that electricity?
No it's not that kind of electricity lol it's potential electric energy
That would be awesome. Can you imagine them powering a water collector using that energy. Generating all the heat they need to melt the ice and possibly if there's extra performing electrolysis on the water to make deuterium.
@@ItachiUchiha-br8ig While you are right, don't you think your degree would be better used helping others unterstand what you understand, rather than using it to make yourself look good, just to put others down?
@@SnakeBush It is actually the same kind of electricity, just not the same type of energy. Obviously the ground being charged like this is not the same as current running through a wire, but ultimately all you would need to change that is setting up wires correctly.
If one were to connect the positively and negatively charged parts of one of those craters, a usuable current would be conducted by that connection, as long as the solar wind keeps blowing, so that the charges are not equalized.
Ultimately, like with all types of potential energy, it just needs a small but spezific adjustment to make the energy usuable.

Chandrayan 3 landed on South Pole of the moon on 23rd August 2023 to confirm water presence.
Chandrayaan-3 did it
The "large" amount of water ice on the moon, really isnt all that much. Its actually slightly less than the total volume of water in Lake Erie, considering that water would be needed for industrial, farming, and survival. that isnt really a long term solution; especialy considering there is no way 100% of it could be converted without a statistically significant portion of it lost in processing or unobtainable due to location
All long term human space exploration is impossible as we cannot survive for long outside our environment however hard we try and replace ecosystems with machines ,let alone physical and mental health issues .
@@MyKharli they said we would never fly too…..
Let’s not be obtuse, how much is Lake Erie expressed as weight in the generic standard “cars”? Let’s be sure we’re comparing apples to apples here.
And you've been there lol
Spoilsport
If you want to protect astronauts from electric shocks, the last thing you want to do use use an insulating material. Weave metal into the suit so the electricity can flow harmlessly through it to ground.
Also - 100KV sounds scary but it's not the voltage that kills you in an electric shock. It's the current. How much charge is there above the lunar surface? A tiny amount is harmless no matter how high the voltage.
@Yummy Spaghetti Noodles LOL. I'm now imagining some kids saying, "High current? Nothing to worry about. Let's climb."
@Yummy Spaghetti Noodles
Because it does and with the current to go with it.
Voltage is what is recognized universally by even the poorly "edumacated"
the issue isn't just getting electrocuted tho, it's the charge sticking to suits and picking up the toxic/abrasive regolith. if the suit is so mediocre that it can't protect its wearer from 100kV... then what about cosmic rays and 200+C temps?
in the end, those issues are still less of a problem than tracking regolith into living areas, imo. even if you only pick up 1 grain per trip per person, the grains will eventually accumulate within the habitat and contaminate it. the solution has to be a very complete one, that can make sure any leftover grains after discharging the suits can be 100% vacuumed up somehow.
the electric charges on the moon is an issue mainly because these charges could make the regolith harder to manage.
@@alveolate who says the suits will have to come inside? It'd be easier to design them to be put on and taken off in an airlock so they never make contact with the living space than trying to find a way to completely clean them; that way they only need to be clean enough to continue operation and you can just have a full cleaning operation of them separately.
@@anthonymullings8539 you make it sound as tho you can just take em off and stash em outside like you don't need a connecting chamber
We have “high temperature” super-conducting tape that could be useful for draining the charge from a mass of solid water, provided the temperature were sufficiently low and was never exposed to solar radiation. I think there are some whose critical temperature is above LN (-196C). I don’t recall the surface temperatures that were mentioned (-230?) but it sounds as if a long tape that was below it’s Tc could be used as a tether, or unrolled / hurled /shot from a point of attachment just inside the rim of the crater, down into the center, to drain the charge, or create a path of equipotential for safe access. Just thinking “out loud”…
Great video!
Thank you Mr. McColgan, for your great work and precise research!

I read a pair of novels a few years ago discussing exactly the electrostatic regolith problem (and also moonquakes!), Moon Beam and Moon Tracks. Excellent writing and great science in there, and this video gives me even more explanation of just what's going on, when talking about the Moon's surface. Thank you for keeping everything so clear and straightforward - for someone like me who knows just enough to know I don't hardly know anything, it really helps me understand!
The electrostatic charge can be increased enough to levitate a vehicle a metre or so above the surface, if they have the same charge. An MIT experiment tested out the possibility in an Earth lab. The novel I'm writing now is about a lunar racing championship with such hover racers.
@@TroySpace Awesome!!!
The accumulation of static charge is like winning the lottery. Placing a large surface area antenna 1 or 2 km above the surface to collect the protons, and running a wire to a web of closely spaced copper wires placed over the permanently dark side of the crater will generate an electric current, which could be used to power machinery, lasers, etc.. As a very small bonus, the combination of protons and electrons will generate Hydrogen in very small amounts. The electrostatic potential difference, if held in check, could be released in bursts, into a pellet of He3-H2, creating fusion, and a huge amount of energy. Even without fusion, the use of the solar wind to generate energy will give Moon inhabitants an energy source that will last 1 billion years. It could also be used in low Earth orbit. This has already been researched and proposed
The uneducated here: Sounds like turning a problem into a solution. Which might be good. Would there not be an issue with the negative consequences of converting polarities of/on the moon to the other? [All things are interconnected.]
wow!! any links to some reading material about that?
Plenty of volts but not enough sustained current (amps)
When I heard 'free' running electrons I knew there was a boon to be had :))

I love all knowledge of the moon (and the universe). Thanks for yet another educational video!
Perhaps the..."Aristarchus Crater" [docking bay entrance] on the Moon would be of interest. Mankind is "Project Organic Intelligence". MOONS - Main Observatory of Organic New Species. Xeno's Observe as their ants Split Atoms. Xeno's start to panic as their ants Collide Particles. Dark Matter will destroy the colony... If the "ants" play with it. Once they crank up the voltage at CERN and 3 upspin particles collide with 3 down spin particles - instant Black Hole. Can't turn that off or contain it.
Love the channel. The knowledge is great but the positivity is greater still
This was the most informative and most surprising thing I've seen in a long while with the negative charges, teflon and rigolite. I've never heard anything about it beforehand. Thanks for this video. Such problems like these are things that the common person would never be able to imagine.
I once became electrocuted by an electric fence of 10000 V DC, but it was conciderably less painful than being electrocuted in my left arm by putting my fingers into a lamp exposing me for 230 V AC, which was very painful. So even though a voltage of thousands of volt sounds bad, it might be ignorable depending on amperage.
You were zapped. Electrocuted means "death by electricity"
It's ignorable because of the negligible charge. You get the full expected amperage for an instant, but it discharges so fast that the voltage immediately drops to near zero.
Using the water/electricity analogy, it's like getting hit by a high pressure jet of water that's only a nanometer long. The high pressure jet might be able to cut steel normally, but it's so brief it can't actually damage anything before it dissipates its energy.
You were shocked, to be electrocuted you need to die.
Polysulfone would be a better replacement for rubber. It has a high dielectric constant and is resistant to temperature fluctuations, and is used in medical equipment because it can hold up in an autoclave
50 years since we have been on the moon. Shocking how long it has taken to go back especially considering the minerals up there.

This is really interesting because if we set up Lunar colonies elsewhere, apart from the poles, solar powered instruments would have to contend with long periods of time without sunlight.
thats why you don't use solar lmao, you use heat power storage to run stirling engines. that way you can use the natural hot and cold cycles to run a heat engine since both have compressive and expansive effects.
@@AppleManiagaming True. I was suggesting Solar for the polar regions (where it might be easiest to to account for the day/night cycle).
For your suggestion, it's fortunate that the Moon's orbit is so predictable.
You always produce such wonderful videos Astrum :)
Thank you Alex for the video! Electric field on the moon is one of the most scifi things I ever heard ever. Again, reality always stranger than fiction.
And chiming what others have said here, maybe we can utilise it in the future!
The electric field is generated by the sun, and reacts with planets and moons largely at their poles where it is mediated by any existing magnetic field. Electromagnetic forces and plasma fill the solar system. Accepted science--the gravitational model--has little to say on all of this, but being that scientists are constantly surprised by what we discover in space, adjustments to our understanding will have to be made.
Thank you for this video, it was very thorough and helpful to answer any questions for humans returning to the moon.

2:30 C'mon Alex... visualising water mass by comparison with cars? Seriously?
What about "600 billion kilograms of ice [provided billion means 10^9 in this case] are equivalent to 600 million cubic meters, or 240 million Olympic swimming pools, or one twelfth of Loch Ness (without Nessy)"? ;)
7:00 That's interesting. Usually, Teflon™ and other perfluorinated materials tend to a negative electrostatic charge themselves. So actually I'd expect that negatively charged particles are repelled and not attracted. Polyamides, e.g. Kevlar™, tend to a positive electrostatic charge, and might thus act attractive rather than repellent.
Maybe mixing those materials would help.

Also a nice coincidence that the timestamp is the 8bit max value. Both limits are Mersenne numbers, one of them prime (127)
you're a gift to humanity, thank you for this
@@creamwobbly probably not. I now edited my comment, because you made me realize it's more likely that it would be an 8bit signed integer
It seems like we would want to apply a voltage to basically anything we want to use up there. The dust is attracted electrostatically, but we can actually use that to repel it by charging whatever we are working with.
Whoever is scoring the music to this channel is killing it. Really cool stuff.
Very interesting video. The Rimworld music was a nice touch.

Thanks Alex
It seems to be a bit disingenuous to say how dangerous the electrical discharge can be. The voltage could be very high with little to no current. It would, like you said, be like being shocked after rubbing a carpet.
Ok then you test it out first.

@@Nah_Bohdi ikr love all the wanna be scientists in the video comments, I'm sure space agencies have thought of the basic solutions they all throw around
True, voltage is not even a unit of charge, and nasa is still planning to land there and not designing their suits to deal with a “high chance of being electrocuted” by static.
tHAT IS THE PROBLEM EVERYBODY HERE IS IGNORING. THERE IS ALMOST NO CURRENT FLOW AVAILABLE.
@Grace Jackson Actually simple electron leakage will discharge it.
Couldn't help thinking about those temperatures being so close to absolute zero and how superconduction might come into play with the materials and electrical fields on the Moon.
-290 is not cold enough for long enough times - superconduction calls for -274C. Doesn't happen until somewhere around Neptune.
@@jessepollard7132 I'll have to rewatch the video to see if the 247° temperature given for the permanently shaded areas were in Celsius.
Celsius for 0°K is 273°. Iirc, iron is around 230°C; the manmade copper compounds, which aren't probably there, is around 140°C.
That efficiency combined with solar cells to generate power for a permanent moon laboratory would be useful. However, being able to use the idea may not be worth it; it could go in a whole different direction such as transmitting power by microwaves.
But.. I'm digressing.
Very compelling copy! Bravo.
Very informative.
Could the build up in charge be mitigated with the use of a network of grounding rods and cables to provide a path for the charge to be neutralised? Alternatively could this charge be stored to provide a source of power?
exactly what I was thinking - just use some grounding rods and chuck some cables over the crater wall. Edit: better yet tether in some super-capacitors to capture that electricity, it's free real estate.
Came down to the comments to say something similar. It means we can potentially harvest energy from our star in a manner different to what we have used before. The question is... How effective will it be?
That's what I had in mind 🤔
@Brent Smith Ha ha. Got it!
static charge can't easily be converted to usable power. IF it could it would be done on Earth.
Truly brilliant, educational and entertaining content, consistently. We're so lucky to have access to this well made quality content. I've never said thank you so.. thank you!
Excellent closing statement!
2:26 If my math is correct, 600 billion kg of water ice when transformed into liquid water amounts to a cube with sides of about 8434 meters. Water ice however is about 9% less dense than liquid water. so that would mean one huge ice cube with sides of about 8680 meters (I think, not sure)
Water @10
Napkin math: 600 billion kg = 8434m, 600 million kg = 843m,
600,000 kg = 84m, 600 kg = 8.4m, 600g = 84cm?
Looks like you got the decimal point wrong (at least if 1 billion means 1000 million).
Achtsekundenfurz Lol 😂 @10 to the negative 11 Torr 🌝
It's 843.4 meters (for water), not 8,434. A metric ton of water cube has a 1 m long (tall, wide) side.
600 bln kgs of ice is 600 mln tons,or 0.6 cubic kilometres
Is there any footage from inside the lunar landers? It'd be quite fascinating to see people in low gravity minus the cumbersome spacesuits.

There wouldn't be any way to tell that it was low gravity. The LM cabin was TINY, with barely any room to move around in, let alone jump. In fact, there wasn't even enough room for both of them to lie down, one had to hang a hammock across the cabin and sleep above the one sleeping on the floor.

So what was the cause of death?
The astronaut received a mild electric shock.
And that caused her to die?
Well it made her arm jerk, which caused the rover to accelerate off the edge of the cliff...
Wouldn't it be more effective and logical to have kind of a "lightning rod" going from head to toes? So it would lead electricity thru it.
Or better yet, why not make use of the FREE energy and turn it into power to charge batteries? If batteries are full, then extra energy could be simply turned into heat or light, just have powerful heater or lights on the suit, so when batteries are full, rest of it is just spent on lights or heater.
NOT ENOUGH POWER AND NOT SUITABLE FOR BATTERIES.
I'd guess the ground isn't conductive enough to just stomp around and maintaining good contact.
You could walk around with a ground wire tether, but, assuming this static electricity can be used at all, it might be better to do that in fixed stations.
Even if you can lug around a lot of equipment with 1/6 of earth gravity :)
That's too interesting, I didn't know even a little about that dangers. Would do Mercury have the same dangers?
Thanks this proved another idea
Awesome channel with awesome content and great quality as always say 🌍💯
Heck yeaaaaaaah new astrum videooooo heck yeaaaaaaah
Thanks!
Pretty interesting; thanks!
watching on 3:27 am morning in India
How have I missed something this big? How did I not know of the moons electrical nature? 😦
Because they invent new stuff on a daily basis.
@@wurzelbert84wucher5 😂 wtf kind of answer is that? 😂 sling your hook bro lmao
Think that's cool, check out Io's electric nature. It's effectively a giant dynamo using Jupiter's magnetic field.
@@jeffspaulding9834 Alright, thanks for the heads up 👍
As a big space fan since I was a child. I LOVE THIS
This is facisnating. Thank you. It would be fantastic if you could include a bibilography or list of sources in the description!
yes!
Chandrayan 3 🇮🇳 landed on the Lunar south pole. India is the first one to land there. If we are looking at setting up a base there, India will have its stake.
Something i just realized. With no dense atmosphere and winds to carry dust, the moon could be a potentionally better place to use solar panels to generate electricity. Of course there is the matter of protecting the panels from solar winds and many objects falling at speed at the moon surface.
Solar wind is not a problem. Your run of the mill solar panels would do just fine against it. The falling object problem is unfixable though so best you can do is pray nothing hits it but the odds are low of it happening anyways.
As tres catorce suggests, the Moon's surface itself is something like a solar panel.
You could protect the solar panels by putting them under the ground....oh, wait......no,.... forget it.
so, how exactly would these solar panels be used?
I am not sure if NASA had found water on the moon first however even if it did find it did not disclose the finding, so effectively it makes chandrayaan the first mission to find water on moon.
Static charges are relatively easy to deal with. just puting some metal on the suit would eliminate the charge buildup by leaking the electrons.
Some poorly written parts to this video about regolith. The Apollo lander had no airlock. This is why Moon regolith was in the lander cabin.
Future human lunar missions will have airlock compartments where outside contaminants will be contained.
* PS. regarding the solar wind/electricity problem. (See an article titled; "Hazards of Solar Wind On Moon" by the NASA Solar System Exploration Research Virtual Institute). From that article;
"The question of how to safety discharge static electricity in space is an old one, notes Goddard Space Flight Center scientist William Farrell,...
As they shuffle along, the astronauts will be like people rubbing their feet on a woolen rug in the winter. Farrell says they may have to wait 100 sec. to discharge the static electric forces they build up after a single step."
* NASA has instruments which can measure static electricity using a sensor that is sensitive to any voltage changes in the environment.
(See the "Voltage Sensors Monitor Harmful Static" article from NASA Spinoff)
With instruments that can measure static electricity, astronauts will not have an insurmountable problem, though moving to and within these craters will be very slow.
- The electronics in current robots however would be vulnerable to such high levels of static electricity.
There are some designs that would entirely keep contaminants out, but a simple airlock would not (though better than Apollo). That stuff will get everywhere.
@@agsystems8220; My basic point about lunar regolith in my original post was to mention that no mitigation information for this was provided in the video.
* The video correctly states that the problem of lunar regolith for astronauts has been known since the Apollo landings.
- What's missing are proposals which have been made (in terms of airlock designs) to mitigate the problem.
- Similar mitigation designs have been proposed for Martian habitats because of perchlorate in the Martian regolith.
* Your response;
@A G Systems wrote ; "a simple airlock would not..."
"...keep contaminants out...".
* I did not write; "simple airlock"
* I wrote; "human lunar missions will have airlock compartments where outside contaminants will be contained."
- I'll explain that sentence further.
Part of the design will be to keep the Extravehicular Activity (EVA) lunar space suits in a compartment separate from the inner living quarters compartment of the habitat. This separate suit compartment would be within an airlock.
- Reference; From NASA Technical Reports Server (NTRS) abstract;
Titled; “Lunar Habitat Airlock/Suitlock”
"... lunar airlocks are planned to be used much more often (every other day) in a dusty, gravity environment. Concepts for airlocks were analyzed by … NASA…”
“A Suitlock (SL) which shares a pressure bulkhead with the Habitat allowing rear-entry suits to remain on the dusty side while the crew enters/exits the Habitat.”
“Objectives… 5. Minimize the intrusion of lunar dust”
Just as well ISRO didn't bother watching this negatively charged video and got on with successfully landing on the moon's south pole.
Maybe machines are safe but not the humans
I love the idea of using the moon's high voltage to somehow install and charge a battery or somehow harnessing the power from almost infinite solar winds. Obviously it would be difficult but it's fun to spitball ideas!
Metal mesh outer layer of the space suit would be worth investigating (if not already done), as any electrical charge would be shunted directly to ground. It would also become a faraday cage, giving the wearer added protection against electromagnetic radiation.
I wonder if this phenomenon could be used as a power source?
If it can, is it more efficient than regular old solar panels? Either way, there must be some kind of shock prevention around buildings, so might as well harness it if you can.
@@MolecularMachine I.K.R?!?!? Tons of power, and we're too lazy to use it.. sounds like a space agency problem..) It's a big club and we're not in it..
Possibly a fair point about solar panels still being a better idea. But this might be a cheaper more primitive solution. I am guessing all you need is two sets of conductive sheet metal plates. One set for an anode and one set for a cathode. Easier to repair also.
I suspect that this may be possible, but nobody knows about the practicality of such a system since it can't realistically be tested here on Earth because the conditions don't exist. I would suggest that this may be among the early experiments on the Moon, and will require a period of development before it becomes practical. That said, lunar regolith is surprisingly similar to volcanic ash, and I experienced the ash cloud after Mount Saint Helens erupted in 1980. There was _substantial_ static electrical discharge (lightning) which was possibly the most terrifying part of the ordeal.
no
Couldn't the solar wind theoretically provide unlimited electricity for a colony under these conditions?
Yes, but at far lower powers than regular solar. No real advantages.
no
NOT USABLE.
Thank You. I've wondered but never seen or heard anything much about why we haven't gone to the moon's poles, where the alleged water is. As I've always said and still do: Learn to live on the moon first, before trying Mars. Seems simple common sense. Mars in my opinion, in the near future is a "one way mission". Thank You. This has been very educational and good narration.
You can't go to or land on the moon. Nonsense from every direction.
I wonder if it might be possible to use that electrical problem as an energy source. Conversion of this energy for use may be also a way to mitigate the problems.
"Shocking new discoveries made at the moon's polar regions." I'll see myself out ⚡️⚡️ ⚡️
Hehehehe... nice.
it actually seems like the best place to learn to thrive off earth considering there are atmospheres out there that would make things easier than on the moon
Thumbs up and subscribed!
Alex.... Your subjects are fascinating, but none so much as your segue to Henson Shaving !
First thing I thought of when hearing about the amount of electric charge was How can we tap into this to power our equipment?
As to the dust. It has a charge, so a wire mesh in the spacesuit should allow us to just repel the dust with a weak electric charge on the surface of the suit.
The mesh should also conduct any buildup of static charge to the ground before any significant voltage can accumulate.
Someone with practical brain. Thanks
Regolith causes red eye-ness? 06:51 Sounds exotic.
Yep, had to re-subscribe ... for some unknown reason I was unsubscribed... Love this channel's content, thank you!
Excellent
Didn't realize how our Moon could be so hostile. Well, at least it may serve as a convenient laboratory.
Convenient?
@@renejean2523 not convenient at all - going into a room and turning on a van-de-Graff generator will get you 300,000 volts in a few seconds.
Harmless to nearly everyone without a pacemaker (and even then mostly harmless).
the video is mostly overhype.
The moon is a harsh mistress
