The Moon has been one of the most important theoretical stepping stones to our understanding of the universe. We’ve long understood that it could also be our literal stepping stone: humanity’s first destination beyond our atmosphere.

Because we're running low on cheese.

Where shall we go the day we run low on crackers?
"We could only pretend that we are the center of the universe for so long when we can literally see the detailed surface of another world with naked eyes" *quote of the decade*
I mean to be fair to scientists of the past observing the heavenly bodies, it does appear as if everything is orbiting around us at first glance.
@@erric288 Not just that, but if the stars were infinitely far away, then it is impossible to tell which is the real center without a third object outside the system. Until we had telescopes able to measure stellar parallax and see the stars do indeed shift as we move around the sun, it literally was an unanswerable question.
And you cant be faulted for being wrong on something it was impossible for you to prove one way or another anyway. Pre-renaissance astronomers were not ignorant they were just limited.
Well we are all at the centre of our own observational universe. So they were kind of right
@B0tch0 You guys ain't getting the quote, he doesn't mean that they had to have all figured out but that the process was inevitable and inevitably quick
Counterpoint. I am the center of my light cone and therefore the center of the universe from my perspective.
"Okay, boss. We finished building your lunar base!"
"Why is it shaped like that?"
"You wanted a **checks notes** crude lunar base."
"I wanted a CREWED lunar base."
My eyes kept swinging to the subtitles to confirm that no, he did NOT say crude.
If Spinal Tap went to the Moon...
I read a sci-fi short story once in which many of the people watching the eclipse were disguised aliens here to just go "Wow, that's crazy!"
Name?
Oh my Glorp! Do you see that Worm Monkey!? Not in 10 trillion parsects can such a spectacle beheld by the naked photosensitive organ!
@@GreenPixel-Moosie I'd have said if I remembered. It was just one of thousands of short stories I've read over the decades.
🤣😂 wow, that's crazy!😂
That would be a huge improvement on silly doomsday invasion stories if, instead of wanting any resource we have, they just wanted our great views.
China was not the first unmanned probe to return rock samples. The Soviets did it with Luna-16 and 20 returned rocks,. and Luna-24 drilled and returned a two-meter core sample.
If You believe everything that soviets or russians tell you, they even have an unicorn, builded the moon, Putin was first to carry those heavy bricks there.... Shirtless... On a bear.... One hand driving the bear, no joke!
@@iamgroot4080 The Russians have a long history of either telling the truth or saying nothing. Unlike the US who lies and or has lied about absolutely everything you could possibly lie about. If the Russians said that they had put a man on the moon, then I would believe that the US probably had too. But when it's something that only the United states of liars claims, I have no reason to believe it.
Wow, curiously to know the weight of the 2 meter core？
@@akakakakakak3084 en.wikipedia.org/wiki/Luna_24
I think Mars is interesting from a scientific perspective, but from an engineering perspective for a society who is looking to expand beyond Earth, the Moon is the easiest way to develop technology and procedures for continued expansion.
we already got to mars, people dont need to go to mars, there are planned sample recovery missions that got their budgets continually cut overtime, sending people would be so much more expensive than a robot that is objectively better for taking measurements because it eliminates human error, the biggest issue in human led testing.
LoL.
I keep hearing people say that, none of them have a business plan, and half of them are Communists.
I'm going to Mars, not "we", I don't identify as a waste of oxygen earthling. I'm just a temporarily embarrassed multi-planetary trucker.
@@jtjames79 you don't hear people when they speak.
@@jtjames79 I, a venture capitalist and ore processing tycoon, wish to go to the moon for the much closer and much less EPA regulated moon rocks.
I think Moon would be a great place to practice before moving on to bigger things. If astronauts get seriously hurt, ill or things go wrong on the moon, then people on Earth can render aid from not too far away. But planets are too far away for those on Earth tondo much to help.
I kept hearing 'crewed' as 'crude' and thought that was a pretty bold comment on the sophistication of those missions
always cc activated for me because I keep mishearing things :(
They ate with their hands
Any space faring vessel we can build with our current technology are doomed to be crude in comparison what we will need to really explore and colonise our own neighbourhood.

Correction 9:38 The Soviet Luna 16 (in 1970) was the first robotic probe to land on the Moon and return a sample to Earth and represented the first lunar sample return mission by the Soviet Union and the third overall.
Too bad Russians are more interested in washing machines and toilets these days
You're of course right, but with recent rabid Russophobia (bordering on 30s antisemitism levels) we'll soon read Vanguard was the first artificial satellite of Earth...
🤓actually
Crazy to think that until there hadn't been a single lunar sample returned since 1976. The entire Luna program brought back only a total of 326 g compared to 382000 g brought back by Apollo program which was even longer ago. Chang'e5 brought 1731 g in 2020.
Russia will never make it back to the moon. If they have a washing machine in Russian homes by the end of the decade, it's already a win for them.
After so many years, being 31 now, I was worried we've truly given up on space, felt like this quote hit too hard: "We used to look up at the sky and wonder at our place in the stars. Now we just look down, and worry about our place in the dirt" - Interstellar, but now seeing this gives me hope 🙂
“that PARTICULAR Cold War” 😬
I've been referring to it as "The First Cold War" for years now. I consider the proxy wars against Russia & China to be one unified "Second Cold War" but some scholars are saying they're 2 different new Cold Wars.
@@Nphen Instead of "Cold War II" It's "Cold War IIa" and "Cold War IIb" 🤣🤦♀
So I wasn't the only one who tripped over that sentence
Chilling.

I love the book, Artemis, written by Andy Weir. At the end of this century, we've colonised the moon and discovered rich aluminium oxide deposits. Andy Weir is the one that wrote The Martian, and Artemis is definitely as worthy of a read.
'We'? The U.S., a shareholder company, a billionaire, or the World, as defined in the space treaty? Or is the space treaty toppled with the Artemis treaty, that supersedes the UN one, and makes basically the U.S. the sole owner?
@@chiron9948 in my comment, I meant 'We' as in, the human race. I don't really recall that any politics were involved in the story. It was just about a space-age street urchin getting dragged into a conspiracy about factions vying for control of the aluminium supply. I think the organisations involved may have been privately owned. Read the book :P
Just wrapping up Hail Mary! I was skeptical about Artemis from the reviews, but I'll give it a shot now based on this comment. Thanks!
Crazy to think that one day soon, we'll have a 4k live feed from the Lunar surface.
With a 2+ second delay
I'm making sure that we'll never settle on the moon.

Lunar Time - needs its own episode surely!
14:09 time on the moon ticks a little bit faster (weaker gravitational field), not slower.
Maybe they meant slower because the Moon orbits the Earth at speed, so moving faster relative to us, and therefor experiences slower time?
@@abxorb Knowing that for GPS to work general relativity corrections on the satellite clocks count more than special relativity, this should also be the case but even amplified, since the difference in gravitational field, compared to the Earth surface, is even larger on the moon than on the satellite, and the moon is slower than the satellite.
I had to think about this for a second to be sure, but yes, the moon's surface is a lesser gravity well than the Earth, and the moon itself is further from Earth's gravity well itself, so it must have less total gravity than the surface of the Earth.
Yes. "To an observer on the Moon, an Earth-based clock will appear to lose on average 58.7 microseconds per Earth-day with additional periodic variations." This is an excerpt from the recommendation for Coordinated Lunar Time (LTC) from the US Office of Science & Technology, see page 2 of www.whitehouse.gov/wp-content/uploads/2024/04/Celestial-Time-Standardization-Policy.pdf
For each 1. 5 billion Earth seconds the Moon expiriences extra 1 second for observer down on Earth. That's one second faster per 47 and a halfish Earth years.
Wow those predictions are extremely optimistic to say the least.
Each country wants to claim with their plans that they'll have a base sooner than the others.
Excellent! Finally, and episode I understood from start to finish!
Always a great day when PBSST posts 🎉
Well, Charon probably doesn’t count anymore because Pluto is a dwarf planet these days…but Charon is crazy big compared to Pluto…
Probably also because I have seen more and more astronomers calling it the Pluto-Charon system. So it seems that it is slowly tilting towards being considered a bi-planetary system instead of dwarf planet and moon.
While it officially (as far as I know at least) is still classified as a planet and moon system that might change at some point in the near future. Which does make sense as the gravitational center of that system is somewhere between the two bodies instead of inside the bigger one as it is in all other planet-moon systems.
@@michs342 That definition of binary system always seemed weird to me, because if you moved Charon closer it wouldn’t be true anymore, but the system wouldn’t feel less “binaryish”, I would think only the ratio of masses ought to matter
Will it be called a bi-dwarf-planetary system?
@@michs342 Pluto is "Bi" confirmed.
Mercury and Pluto are the same size, (+- 300 miles) so there are really only seven planets :)>
Yeah that eclipse was so great, I really loved the cloud cover so thick I couldn't even tell where the sun was
RIP
3 minutes in, and you're blowing my mind more than any physics by putting the moon's significance into context. no wonder this channel is GOAT
14:08 Doesn't time tick a tiny bit slower on earth compared to moon's surface?
Yeah, this.
1) The Moon is further out of the Earth's gravity well than when you're on the surface of the Earth, so time will tick slower closer to the Earth, *especially* if you're following an Earth geodesic at the further distance, rather than resisting it as on the surface.
2) The Moon is following a geodesic with respect to the Earth, so shouldn't have any GR time dilation with respect to the Earth, right ?
3) If you're on the surface of the Moon, and thus not following a geodesic with respect to it you'll have GR time dilation there, but less than if on the surface of the Earth.
And if we trust Wikipedia to have been well sourced, and those sources correctly interpreted:
"The two main differences to timekeeping on Earth is the length of a day on the Moon, being the lunar day or lunar month, observable from Earth as the lunar phases, and the differences between Earth and the Moon of how differently fast time progresses, with 24 hours on the Moon being 58.7 microseconds faster," en.wikipedia.org/wiki/Timekeeping_on_the_Moon
(the citation is www.theguardian.com/science/2024/apr/02/moon-nasa-coordinated-lunar-time which says "ecause there’s less gravity on the moon, time there moves a tad more quickly - 58.7 microseconds every day - compared with on Earth.", which should perhaps be taken with a pinch of salt, given the source).
i thought i had relativity all wrong for a moment!
The Lower gravity on the Moon makes time tick slightly faster - 58.7 microseconds faster than on Earth - every day!
So I'm not the only one who got discombobulated hearing that... happy to read confirmation that among the inner planets we got the slowest time on surface 💪🏆
The measurement of time is nominal, and it was created on Earth, so Earth-time is the default.
My wife and I went to southern Illinois to see the eclipse and it was perfect. One of the highlights of our lives.
They are beautiful. I've seen two. 1979 and 2017, both in Oregon.
Why’s he looking so emotional in this one? Sparkly eyes… dude needs a hug!
0:52 - That intro moon-shot. Beautiful work, PBS Space Time crew.
I am really glad that you created an informative video about the moon's importance in our near future and how we can expect thing to unfold with future missions.
Surprisingly, approximately 43% of the oxygen is trapped in the lunar soil in form of minerals, which means that there is a plentiful supply.
I am proud to support this cause and be part of the research team that is exploring the extraction of oxygen using hydrogen, which will help in generating water on the moon and sustain life.
Excellent work as always PBS!
You're the best science communicator I'm aware of, thanks Matt.

One of my favorite topics. Thanks for covering it.
I saw the shadow of the eclipse a couple dozen times through a colander ... light is so trippy
I have 100s of pictures of the C shaped unshadows of trees and bushes.
Antishadows?
@@christophermullins7163 Ashadow
Careful with that. If you look through the colander, you'll strain your eyes. 🙂
@@Merennulli lol, to clarify, the eclipse went through the colander. My eyes were on the ground (to clarify again, looking at a piece of paper on the sidewalk). Seeing so many of them, each per hole, reminded me of looking through a kaleidoscope, and it's weird that if you joined any adjacent holes, they would become one larger eclipse per joined holes, or maybe not? after all if you joined all the holes you wouldn't see anything ..hence trippy

@@jamesmnguyen not even remotely. Which makes it even more terrifying in a way. Earth wasn't habitable at that time but if you stood there, the whole ground would be shaking and deforming from tidal forces probably hours before the actual impact.

ruzzians should be banned in space then. That'd be great.
How fascinating! This was one of your best videos I think!!! 🙏🙏🙏
GREAT EPISODE!
Feels so Sci-Fi, but the way Matt presents it, it seems really possible!
Thank you for the explanation, and let's hope we can see soon astronauts back in the moon!
That mechanism of solar wind hydrogen reacting with oxides on the lunar surface also explains why phosphine might be found in Venus's atmosphere. It has gaseous phosphorus oxides, which could react with enough solar wind to form PH3 and H2O.
Small correction, Falcon heavy will launch Dragon XL, a new larger cargo dragon.
It's not clear at this point that dragon XL will ever be built or that FH will have any part to play in Artemis..one thing that is clear and omitted by Matt is that starship is needed and will be used for early human moon landings.
Unless I'm missing something, aren't the Artemis missions using the SLS and the Orion craft, which are both NASA-developed?
@@gh0stcassette Orion is not a lander.
@@samuelprice538 Falcon heavy will launch Dragon XL, Unless Starship replaces it wholesale. Better? :V
@@demondoggy1825 yeah I guess. That "unless" is doing more lifting than FH though🤣 I'm pretty sure dragonxl has been dropped. Once SS is flying reliably falcon will only be used for meat, and then only until SS is human rated.

Absolutely love your videos! Thank you so very much!
We’re late on some books we checked out.

I was already pretty convinced on "rare earth hypothesis" of fermi paradox but after watching this video I am 100% sure we are way ahead of any aliens. It looks like it's designed to help humans develop faster.
Yes. Maybe we don't see alien empires colonizing the whole galaxy because none of them could figure out there was something to colonize up there in the first place.
Would we have figured out that the planets of our solar system are more than just moving stars in the sky, if we didn't had our moon as an example of such object ? Would we have built tools to magnify these objects, if we didn't know there was actually something of interest to observe ? And then, how do you get to the idea of gravity, without these observations ? How do you get to relativity without a concept of gravity, and no way to test it without access to space ? How do you understand nuclear reactions without E=mc² ? How do you get from there to quantum physics, to electronics and the wide set of technological advancements those theories provided us with ?
It may be that most alien societies in the galaxy are at best stuck at an industrial level, for the sole reason that they don't have such object in the sky to drive their curiosity.
And it even may be that those societies, without access to space, wouldn't even realize the damage their activity do to their own environment, and are stuck in a cycle of societies rising and self-destructing.
Imo Fermi Paradox is simple, you don't get to have FTL travel. At least as far as we know, this seems pretty fundamental to our reality. And rare earth is also something that looks very much plausible.
We are alone. It is our duty to populate the galaxy. At the least.
If you do a little more digging, Zoo Hypothesis also makes a lot of sense. Our cage is on the edge of the oort cloud.
My take is that we are not alone: we are isolated.
While planets with all the prerequisites for a space-faring technological society may be rare, there are enough galaxies for even low-probability situations to abound. But with ever-increasing distances between galaxies, we'll never be pen-pals, let alone actually meet. (Even the Star Trek warp drives couldn't put a dent in the distance to Andromeda - and it's part of our local group!)
I really appreciate the focus on the moon and just how unique it is. Nobody ever really talks about it. I never realized that our moon and its size relative to our planet is such a rare occurrence. Super cool!
I'm in awe of the moon every time I see it, I may not clap, but I am humbled and appreciative of its beauty. I happen to have a tattoo of the moon so perhaps I'm biased
Really it's because with every year that passes where we haven't gone back conspiracy theorists have even more ammunition to say we've never been 😂
My favorite show. Hooked for life!!
Caption correction suggestion: @5:09 - 5:11 Matt: "Please continue your regular activities", Caption: "Please continue your regular duties"
All i want is some hd footage from the trip to and from the moon. I would watch that on a loop.
I'd have thought we would be doing Mario kart on the moon at this stage seen as they were driving on it back in the day 🫤
I would have thought we would have been launching missions from the moon or a space elevator to an ISS, type station that we launch from.
I already knew h2o could be used to make rocket fuel, not because I'm smart, but because i watched breaking bad.
Excellent video, congrats.
The human landing system does not involve falcon heavy or the dragon capsule. It's based on Starship (the new one).
To expect warfare not to follow where humans go is the height of folly.
I think there were plans om how to wage one during the 1950's.
War never changes
So.... 'moon's not haunted yet, but it's gonna be?
i would also argue that presuming people wouldn't be there to oppose it would also be quite folly.
Muslims will never reach the moon so it's going to be fine
11:00 Major correction: Falcon Heavy will not launch Crew Dragon to the Moon. It will only launch Dragon XL, a specialized cargo spacecraft, to Gateway. That is after it launches a few elements of Gateway to the Moon. Lunar Starship, NASA's first choice for HLS (Human Lander System), will deliver crew to the Moon.
Can't wait 🖖 exultant vid again
Hey-o! Appreciate the Dune analogy!
Hang on, what's this about no humans on the moon for 50 years ? Wallace and Gromit went for a holiday to the moon not so long ago.
That was more than 30 years ago
Yeah and I saw a documentary called "Regular Show" where our two "cast members" went to the moon with a xylophone.
"A bunch of baby ducks, send them to the moon".
Didn't Gru steal the moon? That does count, right?
Wasn't there a secret Nazi base on the moon too?
Human "s"
When he said the space station would be crude and the lander would be crude I was thinking they should spend a little more and make it sophisticated.
The way he said "The rest" had me rolling. We'll get there.
That tiny clip you inserted of the moon speeding towards us in the daytime sky gave me such a horrible stomach churn, haha!
Dragon XL cargo craft. Though potentially Starship might fulfill that roll for an order of magnitude more capability instead if it becomes operational in time. NASA has been pretty quiet about Dragon Lunar Gateway progress.
Why does time tick slower on the moon?
Isn't it that time ticks slower the stronger the gravity is? So on earth time would be slower than on the moon?
the reason why Gateway is controversial is not because its in orbit, but which orbit it is in. it has much higher and more complicated orbit which achieves constant communication, but with such large tradeoff that its considered by some (and me) to be nearly infeasible for a gateway station. another of the main reasons it was chosen is because the rocket and capsule aren't actually capable of getting into more useful, low lunar orbit.
which frankly, should call for a redesign.
It's 9:30 at night and I definitely should be going to sleep but nope, I'm watching this instead.
Spacex's Dragon will not be involved in Artemis. Starship will. It's a pretty wierd mistake to make...
Time ticks faster on the moon not slower
Well faster from an earthing's perspective
You misspoke Matt. You said time moves slower on the moon. It moves faster. Love your show.
Pluto and Charon are a matched pair even if no longer planet.
National and international programs visiting the Moon are a win for humanity as a whole. Private missions take us a step deeper into dystopia.
Exactly... well said...
When I was like 10 or 9 I was thinking about the moon and figuring out we can have space station on it to have launching pad to the universe. How proud I was of myself when I saw the same exact idea few years later on some documentary show.
The issue is it's reliant on the idea we can make fuel on the moon. That's a pretty rough ask. At best we've made methods to make fuel on Mars or Venus. But the moon has no atmosphere. We'd have to process rocks to make fuel which is way more costly than on earth.
@@Skylancer727 Wouldn't it be severely damaging to the Moon, too?
@@Starchaser38 Not really. The moon isn't Earth sized, but it's still absolutely enormous on a human scale, we couldn't realistically damage the moon in any meaningful way even if we tried.
@@Skylancer727Moon has a very thin weak atmosphere technically 🤓
@@Skylancer727 No one was ever suggesting using the Martian atmosphere to make fuel (I don't know about Venus, that might be viable), the plan was always to electrolyze water from it's polar ice caps, which is pretty much exactly the same thing being suggested for use on the Moon here, with the added benefit that the Moon has much less intense surface gravity and doesn't have dust storms to cover up the solar panels powering the whole thing, and it's close enough to Earth that the people running the whole operation can be cycled out regularly and have halfway decent communication with Earth while they're there.
You should do a video on mars sample return. It would be great to go over some of the issues NASA is facing with the current plan and talk about past mars sample return mission concepts + potential new ideas on reducing cost and complexity.
Imagine the benefits to science and our species development if the nations of the world could overcome their differences and work together to achieve these huge milestones. Our potential for development would almost be limitless ✌️
It's an incredible time to be alive
It’s always an incredible time to be alive, whenever that time happens to be.
An important thing about the Gateway is that the NRHO orbit it is in has the lowest ∆V requirements to enter and exit from interplanetary space.
So its an ideal location from which to launch and receive anything from samples to a full Mars transfer vehicle (parts of which are to be prototyped on Gateway) which are also much easier to re-use. All thanks to how big our moon is!
Starship is the only rocket capable of bringing humans to Mars and back, and it won't use gateway. Starship makes so much of what NASA is doing obsolete.
@@firexgodx980 Starship can't do any of those things.
@@fwiffo What makes you think this? NASA's SLS (soon obsolete) is only capable of bringing people to the moon in NHRO. From there SpaceX Starship (and maybe others) will land them on the Moon and back. Starship (which is fully reusable) also will be the only solution to get huge amounts of resources needed into orbit. And it is designed to eventually take people to Mars.
It also has to do with maintaining communication with earth at all times and heat management
Lowest compared to what. A distant orbit about the lagrange points has an even lower Earth access delta-v, which is relevant because departures should have their periapsis as close to Earth as possible to convert all that potential energy into velocity
Nice new credits :)
This was fun!
It's all fun and games until bone loss enters the chat.
It's probably much better on the moon than zero g
they're not gonna spend their whole life there, just some short and long trips
@@ryanb9749 Unlikely, the lunar gravity is only about 1/6th of the Earth's
It's better, sure, but not by much
Mars sits at about 1/3rd, so still nowhere near ideal
And sharp, seal cutting, regolith dust
@@STho205 idk how we can fix that one. Artificial rivers prior to settlement?
A fuel depo or a base like the one in the video sounds dangerous due to meteors and so, or how they gonna protect against it?
I was imaging the Moon on a few nights (and days) this week. :)
None of this has answered WHY we need a CREWED mission on the Moon
We dont. He better served contacting the under ocean and under glacier aliens for some new tech stuffs. They're everywhere.
Well, with recent developments in fusion, fusion reactors are likely to become viable for large scale energy production in the coming decades, and the moon has a shitload of helium-3, which is an ideal fuel for fusion.
So landing on the moon isn't the goal, establishing a base (which would eventually grow into a mining colony) is. A lunar base would also serve as a launching point for asteroid mining, and any given asteroid is likely to have literal trillions of dollars worth of various metals.
because its hard. jfk 1962
@@gh0stcassetteflying robots should be cheaper. They have done it for 50y
I'll admit, I've long wanted to see crewed missions throughout the solar system, but those thoughts are holdovers of my childhood fantasies of myself going to space. In recent years, I've come to realize that space exploration is going to gradually drop off and be approached much like ocean exploration is now - by a relative handful of people with niche interests.
resources and control - that is what motivates any country
theres no resources on the moon and nothing to control once you are up there
it is not any more
most countries on the world had their last conflict with change of the actual border some ~80 years ago at WW2
the rest was civil wars and the 'cold war bullshit' between USA/sovjet union by provoking proxy wars in the middle east
Your statement is 100% true for the time when countries were controlled by nobility / monarchs
resources are exploited by private companies and they can not influence a democracy as easily as indiviuals (kings etc) to unprovoked attack/war - at least that is not the case outside of the US
To be true : it's what motivates any life form.
needing to get just to the moon and refueling from there fixes a lot of problems tbf! "the next" bigger space ship could be waiting for the crew at the moon and we just need a "light" rocket to get them there. I like all this :D
Love that we're getting back to our big night light. Hope we keep fair play up in space, even when companies and rivaling superpowers are at work.
SPACE RACE is the type of COMPETITION and RIVALRY we need. Not War for territories here on this rock.
So war for territory on a different rock.
mister Putin i challenge you to a race !
@@filonin2 still better than this shitty rock that everyone ever has had to die on. Im not interested in being like our primitive and uninformed ancestors.
No, we need the cooperation of all humanity, but I’m afraid this is impossible now and will only happen after some catastrophic event with billions of deaths.
@@filonin2yes
I hope one day in the future, all the nations can work together in the pursuit of space travel.
You should watch For All Mankind, it's set in an alternate history where the USSR beat the US to the moon, which caused the space race to continue escalating for decades, they had moon bases in the 70s, lunar mining operations in the 80s, and a Mars base in the 90s
@@gh0stcassette The premise is slightly flawed: the space race stopped, not because someone landed on the Moon, but because the USSR fell apart. E.g. right before its end, the USSR produced a mind-blowing Buran spacecraft.
@dionysusbacchus4321 it's hard to separate the two, the space race and massive military build up definitely played a part in the disintegration of the USSR
Not until religion is finally relegated to history where it belongs.
Never going to happen. Something about competition for things. Water, food, women.
Can we get an episode on orbital elevators? I’ve always wondered about the concept.
"If you've spent any time in Arrakis..." I was not expecting that line, lol.
It'd be really cool looking up and seeing human activity like lights and other artificial habitats on the moon from the earth. It'll be such a own to nature.
Wonder how flerfs will take such a sight.
"What's that on the moon?"
"...Drink...Coke?!"
Because it's always been our dream to set up a permanent Moon base and then go to Mars to do the same. Luckily with SpaceX's Starship this is finally possible. Previous rockets couldn't take the amount of mass needed to set up an actual outpost so all we could do is visit for a few days
That is: with SpaceX's Starship this might perhaps be possible in some undetermined future.
Starship has a long way to go, it is not a functioning rocket and who knows when it will be. People should stop thinking in fantasies especially when it comes to musk
If you think Starship makes this possible then you haven't paid any attention what so ever to Starship, lmao.
@@NeinStein It didn't take them that long to develop the move successful rocket ever.
@@oBCHANo Last test only failed on re-entry tho, right? Don't really need re-entry capabilities to plop some junk on the moon.
Like, if they quit now, that's still a perfectly good orbital delivery vehicle.
I feel like I heard the music of X-com UFO defense in the background :) Anyway, good to see that space and the moon get some place under the sun (pun intended) in these troubled time !
Since the Moon has less gravity than the Earth, time would tick faster there instead of slower due to General Relativity. However, because the Moon has a high velocity clocks would tick slower there due to Special Relativity.
Maybe they figured the last 50+ years they wasted that it was about time to get going again?
We know more exponentially more about Mars than 50+ years ago. But yeah, they wasted all that time eh?
They realized that creating a moon base is exponentially easier than even landing a human on mars.
It's only because China is going that all of a sudden it's now become a priority again. And China is only going to prove themselves. The whole thing is a boondoggle.
It is rather simple, really: Soviet Union started the entire competitive race thing, with the demise of the former the US lost any interest and motivation for doing meaningful things in space exploration. The only reason that the race is likely be renewed now is: China :) Simple as that.
@@garysnider5342 It is true, it terms of space exploration the time has absolutely been wasted. Thank the bing bang theory and religious institutions for the imaging technology (telescopes) being still developed. Otherwise - there is no interested parties to pay for any of this. Until now, when the military may get involved :(
