- Embark on an interplanetary journey with us as we explore the mysterious moons of Mars, Phobos and Deimos! From their unusual characteristics to the perplexing question of their origin, join us on a space odyssey of Fear, Panic, and Hope.
I have to congratulate Simon on being able to say 'four space hemorrhoids clinging to Uranus' in the same sort of businesslike tone that David Attenborough might use to describe backyard birds.
Simon is a better man than I
Had to have taken multiple takes. If this was a blaze he'd have been on about it for ten minutes. Then told Danny to go back to the basement.
Honestly that's what I miss about the channels he left behind. The new guy isn't formal enough
@@thedarkonestaint6105Am I right, Peter!?
@@Rich-fr2yvnew guy is great, Simon has plenty of channels
I dont think i'm alone in saying the planetary science stuff was the absolute highlight of Simons Geographics tenure. They're often my sleeping playlist. So good to see him bring the same stuff in house.
Correct, my fav channels from him are this one and Warographics
Mega projects is pretty awesome too
ME TOO. I don't know how I'd ever sleep without Simon & Morris M teaching me about space (over and over and over) 😅
@@DerptyDerptyDUM and SEA!
@@johndc2998the Warographics Situation Room is one of the best things to come out of 2023 for the Whistlerverse. Incredible material, particularly for how timely it is.
“Four space hemorrhoids were found clinging to Uranus”
-Simon 2024
Holy shit I'm dying help
Kepler just guessing that there are two moons around Mars is hilarious! Kepler was such a character
"4 space hemroids had been spotted clinging to Uranus."
👌
"Space pebbles" sounds so wholesome. 🥰
This is fast become one of my favorite channels. Almost nobody covers our solar systems moons and I'm weirdly and inexplicably obsessed with them
Theres a ton of astronomy channels that cover them. SEA, Astrum, and John Michael Godier just off the top of my head are good ones.
@@jameshall1300 I've watched all of those and am subscribed to JMG but I still want more moon documentaries. Especially some of the less popular moons
capture near-earth asteroids by nudging them into stable orbit, mine the metals, collect the rest around Venus as a long-term terraforming effort to give Venus a moon.
you can gravitationally influence spin, tidally influence tectonics and atmosphere, create accretion disk shade, etc. Deimos clearly cleaned such a disk with regolith that deep.
@@kingmasterlord I think that is an excellent idea
@@johnfyten3392 I think it's what we should be doing instead of war
I get so excited every time a new video from this channel pops up!
“Honey, you should definitely keep looking for those moons…the neighbor insists our chimney needs more sweeping.”
Thank you for that space hemorrhoid joke - that made my day.
I've also heard a hypothesis that Phobos and Deimos are themselves fragments of a much larger moon that broke apart when it drifted to close to Mars, turned into a ring and then coalesced back into the moons we observe today.
In my hypothesis I believe that one of those moons it's actually the ocean that belongs to Mars.
Perhaps play plan to be desired to put it back on the surface of Mars, the planet could be habitable within 80 years.
Simon! I didn't realize you narrated this channel, I just found it today (LOVE Brain Blaze, DTU, etc.). Awesome.
Hey Simon! Did I say you could have another channel? Geez, just crank out another one on your day off.
Thanks, man. Love your work!
As a non native English speaker I must confess that the only way to keep up with Simon velocity speaking is by watching on 0.75x speed haha
But anyway, great content
So that’s why Doomguy never took any fall damage…
Olympus Mons Supereruption not an option?? Volcanos can launch debris into space... that degree could coalesce the same way an impact moon would form, only smaller...
This is my favorite Simon channel
Clinging space hemorrhoids… 😂 Good one!
According to Arthur C. Clarke, "any sufficiently advanced technology is indistinguishable from magic." So, yes please on Magic-O-Graphics. An entire channel dedicated to mind bending moments in technological achievement? For example, the device I am typing this message on would have seemed like magic just 100 years ago.
Omg i’ve never been this early but i’ve been WAITINGGGG for this channel ever since i found the whistlerverse ! keep these videos coming ❤
I was glad to see this video. The most I heard about these moons was from an unreliable source: three scary Doctor Who audio adventures. Phobos got one adventure named after it, and Deimos had a namsake audio plus a follow-up story. Both suggested that the names were no coincidence.
Glad to have Simon to bring my imagination back down to Earth.
I love learning about space.
I wish Simon was my dad. Don't you wish Simon was your dad too? We'd be brothers.
I always assumed Phobos and Deimos were pieces of mars from a collision, maybe just 2 of hundreds or thousands of fragments thrown up into space with most falling back down, some being thrown into deeep space (maybe towards earth like that ALH meteorite) but 2 maybe thrown in just the right trajectory and speed to settle into orbit. With the orbital rersonance betweeen the two moons stabilizing their orbits. just my opinion.
That makes sense to me, too.
Careful with the magicographics joke. You made jokes about astrographics and warographics in previous videos and now they exist....
14:36 yooo, could this mean that that 3rd moon knocked out Mars’ earth like conditions when it fell?
Canadian Space Agency has been considering the Phobos Reconnaissance and International Mars Exploration (PRIME) mission to Phobos orbiter and lander since 2007.
Oh good grief. When does Magic-O-Graphics launch already?
No mention of the monolith on Phobos???
is this another new channel for Simon?
Oh yes, a fine addition to thyne holy whistling empire
Nope! He dusted off top tenz and renamed it astrographics.
(seriously, top tenz wasn’t his)
Oh my God this guy again how many different CZcams channels do you have man. It has to be dozens
Yoooo, another channel? I have opened my fridge this morning and there was Simon in it...
This dude is everywhere
I loved once proposed mission profile that usd both Moons
I wish Simon could have explained why the moons are too small to be the result of a collision with mars.
It's due to energy. Deimos is so far from Mars that an impact with enough energy to propel it that far should have sent far more material into orbit than is accounted for in the two moons. That's why the "third moon hypothesis" makes more sense.
Good vid
11:32-11:35
Simon doing the moon version of the Pokerap.
What about an eruption or two of Olympus Mons?
Since Olympus Mons reaches outside of Mar's atmosphere as it is, there had to be a time when it was still active and was at or near it's current height. I haven't done the math, but I'd imagine that already reaching outside the atmosphere, an eruption could launch a couple chunks of basalt into orbit, couldn't it?
22 and 12KM? How did the space stations from DOOM even fit on them??
At 1.8 g/cm3, Phobos is 30% void space. It's a fragile rubble pile.
I'm aware that there is a hypothesis where Phobos and Deimos were once part of one larger moon that broke apart into the two moons we see today. I then started to form my own theory around it where since Mars is much smaller than Earth, this hypothetical moon would have orbited much closer to Mars, causing it to be tidally locked with Mars where one side of the moon would always be facing the same side of Mars. This would also allow Mars' axial tilt to remain stable, and also cause internal heating in the planet's interior due to the gravitational pull between the two objects, allowing an early Mars to maintain liquid water on its surface. Then whenever the moon broke apart, Mars not only would no longer have been able to maintain a stable axial tilt, but would also loose it's source of internal heating. This would eventually lead to Mars becoming geologically dead and the weakening of its magnetic field; leaving Mars fully exposed to solar winds, which would strip Mars' atmosphere and most of its liquid water.
What if Olympus mons did a massive explosion and sent tons of lava into a space hardening into these two moons
What goes up must come down.
Anything leaving Earth and going into space will fall directly back down and crash back into Earth, that includes rocks, lava, rockets, etc. There IS gravity in space.
In order for anything to STAY up there, it has to be travelling at a very high speed. the reason it seems like there is no Gravity is that things like the space station are basically 'falling' back to Earth all the time, and so are the people inside, they are falling at the same speed, so it only seems like weightlessness. The forward speed keeps them from crashing into Earth. If the space station stopped moving at 17,500 miles an hour, it would drop like a rock.
So for Lava (ejecta) to be shot out of Olympus Mons and STAY up there, it would have to get shot straight up into space (60 miles minimum) then take a hard left, and accelerate to 17,500 MPH.
heeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeej .. keep it up... keep it up !!!
they were placed there. im assuming it has something to do with the phobos monolith
I believe that a significant problem with any theory about the two Martian being anything but captured asteroids is why does Phobos order Mars retrograde, while Deimos orbits in the "normal" direction?
Your poker face has improved Simon
There are other possibilities for the origin of the moons of Mars. Perhaps two separate impacts created the two different moons, or a giant impact created one moon, and that one moon had an impact that broke it into two different moons. I could go on, but you get the idea. There are thousands of options for the source of Mars' moons.
Very cool
i worry for anyone named mos. simon repeatedly tells them to die.
im also on the lookout for this "Foe Boss"
And, speaking as an American ... it's real nice to be getting science results that AREN'T coming out our tax dollars!
1. Theia impact is not a known fact, it is a hypothesis. A leading one, yes, but still a hypothesis.
2. Quite optimistic to assume most of us can do 12 km casual run 😅
The moon is big because it has to match the ego of earthlings
7:35 You talked about the two moons, one getting closer while the other one is getting farther away. But what did the report say about the speed of the two moons? Where their orbits speeding up or slowing down?
You see, as an orbiting object (Phobos) gets closer to it's parent. The orbit should increase. When this happens, it should slow it's decent into the parent object. If this keeps happening, it would be possible that the decaying orbit will stop all together and even move away. But this will happen over a long time. As in thousands of years.
Likewise, the same thing could be happening to Deimos but in reverse.
Pretty sure the scientists thought of those things
Phobos will reach the Rosch limit and vaporize itself well before that would happen.
Question: if those two pebbles were any bigger and rounder, would they have a bigger impact on Mars?
Deimos shipyard makes the best warships
I’m having a tough time trying to imagine why Japan didn’t think to include a kind of reverse orientation retro ion thruster system on the lander as a safety measure to keep it on the surface of the moon and ensure the 1/1000 gravity wouldn’t be an issue
Simon just gave the shout out to his next channel... Magicographics
It sounded like you said hemeroids hang on to Uranus 😅
He did
@@captainspaulding5963 lmfao 🤣 he did!
Earth: If those are moons then Pluto is a planet
could they be from volcanic activity in mars past, it does have the largest known volcano in the solar system
Reminds me; I challenge the Chinese, Japanese, and Indians to go for another first, one of you should do a Neptune orbiter mission.
One of those moons is actually the ocean that belongs to Mars .
One of those moons it's about 80% of ice perhaps you should put it back on the planet from where it came from .
And you could quite possibly have to start of a habitable planet within the next 80 years
You can tell the image of Kepler was AI generated, he has six fingers on his left hand.
Bing probably knows tons of information about Kepler's scientific work but it doesn't know how many fingers he had. 🙂
Maybe it's a reference to The Princess Bride?
What about Pluto? It has a huge moon by comparison and they appear to be of the same material, most likely forming together.
Personally my thoughts line up with the 3rd Moon Theory more. Even more than my own original theory that they were small pieces that escaped our gravity during our Moons birth. Did they ever run those in their computer program? You figure there were chunks floating within the Earths orbit for some time, millions of years even, and they all went somewhere. Venus, Earth, Theia, and Mars were too close within the system to have collected that much of a difference in dust in the proto-planetary disc of dust stuff when they were growing. They all should have some common building structures of the planet.
What magnification do we need to see these moons of Mars?
Some meteor fell to Earth from Mars. Some Theia smashed into Earth making the moon and sending chunks to Mars.
I wish we had a moon orbiting our moon. And an even bigger second moon that was mostly visible in the daytime. That would totally fucking rule!!!
Probably not something to wish for... it would interfere with the natural ebbs and flows of the oceans. This in turn would reek havoc with weather patterns. Probably not a fun time and since the weather would provide plenty of clouds... we wouldn't be able to get a great view of the moons.
@@darrenlane6316 what if this was always the norm??? And we evolved with the extra satellites from the beginning of time??
12:34 *giggles like a child*
Idk enough to know if this is a stupid idea, if it is pls tell me why. But what if Mars and Earth were close-ish when Thea crashed into Earth - could Phobos and Deimos be chunks that were thrown out from Earth/Thea impact and then captured by Mars? Would the age of this impact explain the elliptical orbits? Ie they have become elliptical over so much time, but were more eccentric previously? Someone smarter than me, pls tell me if this makes any sense at all!
Maybe that's possible. But, once they figure out what they are made from, they can confirm or deny it's origins being from Theia or Earth or Mars itself.
The lizard people that inhabited Earth before us pulled them out of the asteroid belt, into Mars orbit, and mined them for minerals. Along with other rocks, that have since fallen out of orbit.
Because they were so successful, they decided they could put an asteroid in earth orbit to mine. Something went wrong.
It looks Like the moons used to be 1, and collided with Mars look at the surface of Mars and you could see where the collision happened.
The left overs of the first nuke war
dibs if one's a ship
how many writers orbit the Whistlerverse? The world may never know.
So mars will have no moons one day ? Could mars moons be a part of our moon when it hit earth then got pushed out
18:17 I guess we'll find Anakin Skywalker on Mars as well.
Probably not, he hates sand... it gets everywhere. 😜
@@darrenlane6316 I should know. He hates me as well 😂
Did you ever read the "Colossus" series?
maybe when Jupiter was moving through the solar system it snagged enough material to starve the moons of any other material, leaving them as they are today?
They might be small but they would end most of the life on Earth if one hit us
Massive volcanic eruptions.
What about a massive explosion from Olympus Mons millions of years ago that ejected enough matter into space and it formed the two moons
You didn't mention the alien relic theory
I know nothing about astrophysics so this might be a silly idea but can anyone offer a reason why the formation of Phobos and Deimos isn't a result of an eruption from Olympus Mons?
I'd say due to the interior of Mars and then level of viscosity of the mantle.. it's highly unlikely. Think about how tall Olympus Mons is. It basically oozed out of mars to get that tall.
@@zerodadutch6285 fair enough
I love the topic. I can’t understand a word you said. I think maybe you’ve had too much coffee.
Kepler is Dr Strange.
12:39 "Deimos is orbiting too far away to have been caused by a giant impact" This doesnt even make logical sense. Obviously objects impacting planets can spray out material fast enough to escape its gravity well and reach earth. Which means the possible velocity range of chunks thrown ito space from a panetary collision get up to and surpass orbital speeds. I mean we have pieces of mars that have been found on earth. Therefore, to say any speed or trajectory that could result in high orbit around planet is not possible, when you have hard evidence for at least greater speeds than are needed, and can logically infer smaller speeds and trajectories with smaller radii (we have to assume that SOME of the debris from a planetary impact will fall back down on the planet itself) is ludicrous.
It also doesnt take into account the orbital resonance of phobos and deimos, which is 90 percent of the reason that one is moving closer to the planet and the othert is moving away. Orbit interactions between bodies in a three body system, where two bodies orbit a lrger central one and are allowed to achive orbital resonance, which two orbiters around a parent body will naturally fall into over time, leads to the outer orbiter being ejected, and the inner orbiter being driven towards the planet. Deimos orbit is only as far out as it is due to resonance with phobos.
17:41 "so close to mars its thought that phobos has over its lifetime, collected material from the red planet, bits of ejecta blown into orbit by meteor impacts" Ummmmmmm, how can this line, which clearly indicates material from impacts can reach orbit, or at least phobos orbit, and either hit the moon like a bullet on its way by, or falling into a similar orbit so as to run ito or be ran into by the moon as it orbits, also exist along side claims like, "It can be from an impact" it either can be from an impact because of either speed or trajectory, or there is a possibility it could be from impact. If impacts are casuing material to reach escape velocity, then there is however small a chance that some of that material is traveling at just the right speed to enter orbit. If trajectory is an issue, then you would have to explain why you can have a trajectroy that can reach earth, and a trjectory that falls back to the planet, but also why you couldnt have the inbetween trajectory that results in orbit. What physics rule prevents the middle velocity and trajectory, but allows the larger and smaller velocities and trajectories. it just doesnt make logical sense. at least not with my current information.
If we can't properly classify mar's moons... How can we class pluto? #plutoisaplanet 🎉
Would like to crash Phobos into Mars if I could I feel like it would
Really help to terriform Mars. depending on where you crash it,
It would add a large amount of
Co2 to the atmosphere mabe it would even trigger volcanic eruptions on Mars.
I think It's just what
this cold red rock Needs.
They actually do this in a book series by Kim Stanley Robinson ( called the Mars trilogy, for some reason 😂 )
They should name the 3rd moon whatever the Latin version of "Loss" is
Please do the math. Phobos is decaying 2 meters every 100 years, not every year.
Please edit or pin a comment highlighting the error.
