Thanks for all the news, Fraser! 😊
Stay safe there with your family! 🖖😊
IO-IO... come one.That's worth a chuckle.
Your content has spiked into the excellent category over the last few weeks! 😃
ugh this coulda gone on forever :')
im so happy to have stumbled across your channel recently! I really like the minimalist theme for the coverage dude ^__^
-it almost doesnt feel right saying that as I feel we're used to minimalist being reductive cuz ..duh? lol.. However, I feel you guys add the minimum amnt of 'frills' needed to convey the experience and leave it at that.. I find it SUPER complimentary ^__^
Nice content as always :)
I just recently joined as a patreon, and must say I'm enjoying membership thus far. Your "nerdy" discord chan is great, for example ^^ Thanks!
My minor was astrophysics back in the early 80's. I've been watching your channel through 2022 ( mostly because there was nowhere to go... just kidding). I get the pessimism folk throw at you. One title: The Moon Is A Harsh Mistress. Keep it up and I'll keep the faith. DH
Hey love the show! Keep it up
I was very disappointed when the Asteroid Redirect Mission was canceled. So many people seemed to be saying "Who cares about asteroids, let's go to Mars."
That mission would have helped us not only progress with the kind of tech needed for Earth protection, but also with in-situ mining and manufacturing; things that will help get us to Mars.
It seems that people who only know space based on the 6-o-clock news, are slowing our progress.
Man, with all due respect to the JWST, the DART mission should have been the space story of the year. Webb is great and all, but we've had great telescopes before and will have more in the future. The DART mission represents the start of mankind's ability to protect itself from existential threats, and affect the cosmos for our benefit. That's bigtime.
DART wasn't a first either. The deep impact mission did something similar almost 20 years ago. The difference is that the deep impact primary mission wasn't to change the orbit if the asteroid but it was a secondary mission. So they hit a larger asteroid that didn't have a companion and weren't able to measure a noticeable change in it's orbit.
If you haven't heard if that mission (I'm not saying you haven't) check it out because it's pretty interesting. It was caught on video like DART was.
You know they've been working on JWST for over a decade right? The technology wasn't there for dart at that time. The lessons learned and technology developed with JWST are what make dart possible.
100% agree
@@christopherleveck6835 20 years on JWST and the project was much more complex than DART. Yes the tech for DART was there, they did a similar mission in 2005 I mentioned above, it was called deep impact and they also recorded the impact from the impactor and the orbiting mission satellite.
100% agree.......big W
Thanks!
Thanks 👍 👍
Thanks Fraser. It's a shame the Near-scout mission attached to Artemis failed. It was a super interesting mission with an interesting technology test.
Lagrange points!!😄 And congrats to South Korea! 👍👍
Awesome show
Hi Fraser, love the show. Just noticed when looking at the amount of twilight that I get in Toronto that it is longer near the solstices but shorter at the equinox, why is this and does it vary due to latitude?
Thanks
Did ya hear about that restaurant somebody opened on the Moon? The food is pretty good, but its got no atmosphere.
4:30, peak fraser cain
10:11 very neat idea for this MPS for Moon with visual identification of one's surrounding.
also, printing a landing pad on Moon from orbit via huge microwave laser, with possibility to speed-up via some rovers on ground managing 3d-printed layers, sound nice unless you think about this big laser over one's head while walking
@FraserCain regarding binding agents for building structures on the moon, how strong an agent is needed? With low gravity and no wind, isn't it possible to build sizable, durable "sand castles" as we do on a beach? Meterorites and moonquakes aside, it would seem like a weak binding or minimal support structures would be needed to hold up the regolith. Also, does it make more sense to build up, vs. digging down to make a shelter? How difficult would it be to make underground tunnels and cities? (I realize the tunnels need to be closed off to keep in the air, etc.) It would be interesting to have a story discussing more of the issues and ideas for building stations on the moon.
Colonies on the moon make a lot more sense that colonies on Mars.
Especially on the way to Mars, as you already have Moon's orbital V and zero atmosphere to fight and the possibility for in-situ fuel generation from regolith.. I don't understand why it's such a hard concept.... would you drive to New York for a big mac?
Fraser, I've really tried to understand your FERMI position, and I know you've said that if you don't understand the paradox, you don't understand it properly, so WHERE can I find your best explaination for your position?
Thanks for all your great work.
That telescope at L1 scanning for asteroids will also be useful for identifying asteroids that are easy to reach for mining purposes, I'm excited what space-industry opportunities will come from that. On the other hand, I wonder if North Korea or another nefarious entity can redirect a risky asteroid (that is predicted to not strike earth by a medium-small asteroid) to strike a specific city?
This might be your best video thus far. Thank you
Harvesting energy from space ??! I like that idea ! Are we attempting to climb the Kardashev scale ? 🌞 interesting..
It sounds like we will have to build structures on the Moon from the Moon itself (At the very least it would be much more convenient)
1 Can we figure out how to do this on Earth
2 Or do we need an airless environment
3 Or do we need to go to the Moon ourselves (maybe send a vehicle with the tools to attempt it; maybe even use remotely controlled vehicles to eventually build the base itself)
Thanks Fraser! Great content!
Is there a potential habitable zone around a black hole's accretion disk?
It would be great if we could create a telescope, that could see Oort Cloud objects. Even if it were objects passing in the line of sight,of distant stars.
Hell yeah!!!.. one on the "dark" side of the moon, for Oort Cloud objects, one on the Earth facing side for inner solar system objects when the Earth occults the sun. That would be sick! Would take quite a few trips though..) Isn't it stupid we're not using an existing massive satellite with a nice stable orbit? Even Mars missions make more sense from the moon, as you already have her orbital velocity, and no atmosphere to slow your ascent.. plus if you can get fuel from regolith............. We're really crawling at a snail's pace in the wrong direction.
The story of humanity is the story of the gradual removal of existential threats. Wolves, starvation, disease, no longer loom as causes of human extinction. Here's to adding planetary impacts to that list!
what happened to that asteroid observation mission that was planned to be on solar orbit between earth and venus?
the one that KSP referenced when asteroids were added?
Wait, Juneau is still active? I suppose it would, voyager was till not long ago, just haven't come across any updates for some time
Miss your outside videos. Don’t be scared of the 8ft of snow 😂
Hah, it's just so inefficient. I used to do a 3 minute video a week. Now I can do hours every week in my studio.
Hey Fraser, I think the space based solar power should be great once we can manufacture the solar panels in space from materials we harvest in space. Now, obviously, that is a loong way off, but it could be a good backup plan in we never manage to crack the fusion. Also, research in this could help fund the development of solar power here on earth, which could benefit us even in the short term.
May I ask why so many probes have been launched to jupiter, Saturn but except for voyager why no future missions to neptune and uranus
Hi Fraser Cain. The problem of navigating on the Moon is much simpler than you think (or the way you presented it here). One only needs to look at the Earth for navigation. The Earth stays at the same spot the whole time (the Moon turns once on itself as it goes onetime around the Earth). If you keep track of the position of the Earth on the Moon's sky you cannot get yourself lost. End even if you get yourself lost you can follow your footsteps back the way you came. There is no wind on the Moon to erase your footsteps or the tracks of your rover.
I read all about this as a child in the romances of Arthur C. Clark. One has to search for simpler solutions if one wants to colonize the Moon someday.
Very cool info, however, I think navigating on the moon it’s not about not getting lost, it’s about finding and going to a very specific location, for instance for collecting samples.
Where you live you don’t need gps to find your way back home, but sure you need it to deliver a parcel to an unknown address.
That only works on the near side.
Fraser is awesome....
Universe Today is awesome.....
thank you Universe Today team for your work and efforts
When the topic is the moon we always hear about regolitt, but are there bed rock on the moon?
I guess a space elevator would be a very good idea on the moon? But that must be anchored to something more than regolitt baked with magnetic stuff, or what?
Off topic, but why can't crew dragon bring the three soyuz spacefarers back. Can't crew dragon handle seven in a pinch?
I've got a 17 and a 1/2 inch dobsonian what kind of gear do I need to look at the eruptions on Io? I'd like to give it a shot. A close friend nearby has A C14Hd Edge. I would think one of us could get something.. Can you put me in touch with the guy doing it now?
Here is a very short presentation by the guy th-cam.com/video/kUsRsVCoyD4/w-d-xo.html The telescope in the background looks smaller than yours. Here is an article, 14 inch www.psi.edu/news/iosodium
That method for navigation for the moon is called a resection, pre-GPS navigation 101 for earth. Basic Navigation.
Conducting a resection you need three or more identifiable far points ideally equality spread apart. Then record a back bearing, plot those back bearings on your map and if you have been careful and accurate you'll have small margin of error each plotted line makes when they cross over each other. You are in the centre of that. If you are good you can do this in a couple of minutes. Depending on terrain you might get away with one back bearing or even just a mental calculation if you are really good. Which is exactly the method Fraser referred to that humans do all the time, except in unfamiliar terrain using a map to make the terrain familiar.
Where do I place my order for a robot body so I can see all this stuff come to fruition?
It's not a matter of if It's a matter of how often ??
Note that while beaming space power to Earth is "inefficient" it is the only way aside from nuclear fission and fusion which can exceed Earth's total insolation budget which must be shared with all of the sun driven processes from the atmosphere hydrosphere biosphere etc. by the second law of thermodynamics.
Of course that only works if the arrays you are using are not absorbing light that would have reached Earth but does it matter how inefficient it is when those photons would have never reached Earth or any other solar system body in the first place as the traveled out into the galaxy at large? That is the use of space based solar because if you don't want to render Earth uninhabitable by destroying Earth's weather systems via overexploiting solar, wind hydropower etc. and you don't want to use nuclear fission and or don't have nuclear fusion(remember that the current reactors plans mostly depend on making tritium from the already highly scarce and finite supply of lithium).
That element is already very important with roles not only in technology but biology and such fusion reactors would irreversibly destroy it which is a problem because Earth as the largest rocky body represents the single largest accessible lithium source short of extracting the metal from the deep interior of Jupiter or the convective outer envelope of the Sun (Stars destroy their lithium). There is also talk of doing this for Beryllium and Boron which are likewise also extremely rare in the Universe as high energy cosmic ray collisions are the only way to make these elements. It is so short sighted and stupid. >_
An addendum to my previous question about the Chinese Space Program. Whether you make it a video, or include it in a question show, I would very much like to be anonymous for this one please and thanks.
I get that there's apparently a lot more water than we thought on the moon, but how does the water stay there? I understand hydration of minerals, just take some Epsom salts put in a pot and melt on your burner ,that's mostly water! But in the vacuum of space constantly under the sun's heat, how does it reach an equilibrium with that much water, seems like a lot, like someone's exaggerating numbers or unfortunately grabbed a mineral that has a lot of water naturally like Epsom salts..
Hello! where can i post a question for the Q & A section? or even find out if it was readed, in case there´s no answer? can´t find it on google (the answer to the Q i wanna make). Excelent content. Thanks
You just post it anywhere on my channel. I see everything.
@@frasercain I have! asked twice if stellar flares or stellar ejections have any effect on the orbit of his star, assuming a star is kind of a massive nuclear rocket (just remebering your Answers about ways to get us into space)... I assume that if there´s an effect, it should me minuscule, but i got curious. How goes the saying? theres no dumb questions, only dumb inquisitors. Hope this is neither...never know.
The flares happen randomly in all directions, so even if there was an effect it would be cancelled out.
hmmm
Wouldn't it be easy to create a lunar GPS satellite network? An LPS if you will. I don't see the point of an image based navigation system.
Hey Fraser, do you have a video about... the whole basics of the Chinese Space Program? I know you've mentioned various projects like the space station and moon landers and space lasers, but I think their whole program deserves a dedicated video. Do we even know what their goals are?
If you've already done it, just respond with the video title. Thanks.
Are you aware of a youtube channel called Dongfang Hour? A French guy who confines himself to discussion of only the Chinese space industry (in English).
re NEO Observer: what is "Earth's blind spot"? How does putting it at L1 improve observations compared with Earth orbit? If it's a sunshield like JWST's, it won't be able to look close to the sun.
The idea is that in space, you can't see the dark side of an object. Thus any object between earth and sun is invisible because the illuminated side is facing away from the earth. To see an object in this zone, you have to get between it and the sun.
Maybe we can get a weeks warning before the next Chelyabinsk meteor comes from the direction of the sun.
I mean with ESAs moonlight Initiative PNT on the moon shouldn't be an issue soon anyway.
Is Io I/O located in Iowa or Ohio (please)?
I don't know.. but the way they pronounce it, it makes it really hard to rhyme with anything... I say we pronounce it identically to Yo, yo! And a new generation of nerdy rap songs will be born.
Arizona, guess it is dry and clear skies there.
Question about building on the moon:
What is the melting point of luna regolith? And, is focused sunlight enough to melt it?
Using micro waves feels energy intensive when solar is free.
If solar is free then use it to make microwaves since it's so much more efficient than sunlight for heating.
@@filonin2 The light from the sun has about 1.36 kW/m². Solar panels have an efficiency of ~20%, so you get 272 W electricity of a square meter. A good micro wave has an efficiency of 40%, so the output in micro waves is ~100 W. Now comes the part I don’t know, how much of that micro waves is absorbed and actually used for heating the regolith, I guess not all.
The average albedo of the moon is 0.12, meaning it reflects 12% of the sun light, and absorbing 88%. 1200 W of that sunlight per m² will convert to heat. The complexity of a parabolic mirror is way less than that of a setup with large solar panels and micro waves.
Only huge advantage of micro waves I can see is, it is easier to direct to a small target.
11:00 다누리 = Dah-new-ree
But your Korean pronunciation is still better than most of our Chinese 😆
Io, is the moon, Vulcan, the name is Vulcan.
Need the the equivalent name for ice liquid eruptors
Crycan Cryocan .
if we could transfer power between orbit and the earth surface, clearly we would use that to transport power to sattelites. not the other way around.
❓ Can we expect to see future Starships delivering packages around the world like FedEx and UPS? “SpaceXpress”
Planet Express a la Futurama 🙂
9:53 topology? I'm sure you meant "topography"
cool your hypercube..)/*
I don't understand why they don't send a lander to Io. It would get several mega rads of radiation a day but it is nothing a mechanical computer can't handle.
Space power = orbital weapons platform.
Moon base for mars. Mars base for asteroid mining, asteroid mining for metals, far solar system moon mining for energy. Methane.
Convert the methane into what you want for fuel.
Y’all know that one episode from Love, Death and Robots?
I hope if this infrared Near Earth Object Surveyer can actually see the infrared light signal coming from the micrometeorites that can potentially hit James Webb... If we somehow know that th e space patch is clear, we can point james webb in the direction of its velocity ( risky direction) and can take multiple images... By the way, why is James Webb not sending any image back to earth? It has passed 20 days...
That’s cool that the sun is making water on the moon, means it’s happening elsewhere in the galaxy, which should increase the chance of life, eh? And also Fraser, just to be pedantic, that isn’t a photo of the earth rise, from the moon the earth will stay in the same place (won’t it?….)
Did that Chinese returned lunar sample confirm how much helium-3 there is available on the moon?
Take a look at "Markus Kayser - Solar Sinter Project" on TH-cam. Direct 3d printing with a giant Fresnel lens in the sand, could be scaled up to building size on the moon.
I have seen that. Whatever can get the energy into the regolith will do the trick.
We already have a space force, so it only makes sense to have a space power. Hope they won't try to zap me from orbit though.

With technology. Whoever controls space will have the strongest military. Advanced military technology is nothing without satellites
I understand that it's more expensive to get to the L4 and L5 points than L1, but L4 and L5 are inherently stable whereas L1 is not. Therefore any mission to L1 is limited to the amount of fuel the craft has onboard, whereas L4/L5 have much longer lifespans, plus L4 and L5 can still cover the blind spots.
Can't wait to see the results of the Caltech experiment!
DART will be able to carry twice as much fuel. If JWST can loiter around for 20 years. .
@@christopherleveck6835 this is not a DART mission, it's an observation mission looking for asteroids inside the orbit of the earth.
2:08 What do you mean by "Earth's blind spot"? What and where is "Earth's blind spot"? - Can we not look at the sky from anywhere we want?
We can't look too close to the Sun.
@@frasercain Oh, I see. Thanks. But wouldn't those asteroids move away from the Sun periodically if they were to hit the Earth...
@@frasercain And one more thing. Since it is located at L1, wouldn't it have the same difficulty to see objects close to the Sun?
If it looks "out" from L1 towards the Earth and its surroundings then we can get a warning the next time a Chelyabinsk meteor is coming, not a warning long in advance but a few hours or days could help too. Public warning to stay away from windows and a heads up to emergency services.
Thank you to China for making Congress loosen its pure strings, it seems nothing gets done when there is no real competition.
I wish I could be optimistic about the space race with China, but I’m actually convinced they have major military objectives, including on the moon. China has a history of claiming resources for themselves and using military force to maintain control of what they lay claim to, and I honestly don’t see that trend changing in space. I think western space journalists should be a bit more critical when covering the implications of the new space race. If you are taking China’s state media announcements at face value without weighing what western militaries and intelligence agencies are warning about, I’m not sure you are getting the full picture. Even NASA’s Bill Nelson is sounding the alarm on China’s real objectives.
I recommend listening to Peter Zeihan on China. As it’s future is not going to be as dominant as we were led to believe.
They're still quite a bit behind. The rover they landed on mars was far inferior to the spirit rover nasa landed over 20 years ago and was a basic cheap copy of the design. I think it only survived a few months. The biggest worry in the short term is if they are able to steal tech from the U.S private industry like Spacex and leapfrog western space agencies.
Their mission failures aren't reported often either, not even by western media.
In time they will develop this stuff in house, they have good universities and a lot of students studying.
China is insidious and oppressive… The very culture is corrupt and dishonest right down to young children…
@@kadourimdou43 massive demographic collapse is coming and it will shrink their economy in a devastating way… couldn’t happen to a better country…
Military Madness was a sweet game back in the day.. Lunar warfare.. it'll come to that..
The last "planet killer" was when? Ok. In all probability you're diet is going to you. But its fun pretending.
Umm, we've been using "Space Power" since pretty much the beginning of life. Ok but that's not electricity... even then we have been generating electricity from space for over 100 years (hydro) and even directly with Solar Panels for decades now. Power in space? Yup we do that too. It's how the ISS keeps going (and most other space craft). Oh, you mean beaming power. We've been doing that a long time too. They are called radio waves and the old crystal radios converted this signal into power since the dawn of radio... spark gaps before that. So none of this is particularly new. People don't normally use high power microwave feeds but people have already been injured by the microwave transmitters (cooked, got radiation sickness, etc.) and so sending power in this fashion is in general limited in power for that reason. That is, it is not something we can't do already (we already have the tools) but something we limit for safety (or something that has already been weaponized and not talked about much).
Like
If NASA detected an asteroid that was going to hit China/Russia/adversary, do you think they would warn them? Would they dedicate resources to a deflection?
Yes cuz it would still affect the rest of the world.
Question: if I had an amazing cryogenic sleep pod and wanted to witness the end of the Sun, what would be the best way of surviving?
I thought of digging a deep hole in the moon to be safe from meteor strikes and waking up for a week every million years to check for any new threats but I I'd be dead long before the Sun 'died', even at the rate of one week every million years.
0:33 we don't have to go back 65 million years to know that, just 7 or 8 years will be enough. thats when chelyabinsk happened, innit?
10:44 are they gonna do that for the whole moon? YIKES, that's gonna be one GINORMOUS database...
16:18 i think this power transfer is an even dumber idea than solar roadways, which is of course not worth anything.
The water comes from Earth as the Moon spends time in the trail ?
Now, there is an interesting idea! Looking forward to some isotope measurements of the Lunar water.
Between jobs...
If the universe isn't infinite what would be beyond here it ends?
