Most rocky planets have pretty consistent surface features, with a fairly even mix of mountains and basins in each hemisphere. This is NOT the case on Mars! What do scientists know about this mystery?https://doi.org/10.1038/nature07070

Mar’s surface is actually a wasteland with buried city rubble caused by a nuclear weapon which destroyed martin civilization. There is strong evidence of nuclear fallout isotope that can only be created from nuclear related weapons
So, the first comment thing is 5 years too late, but
First Comment (I think)
Mars isn’t messed up, YOUR FACE is messed up! 😎
Mr Nerd is back
And this explains how the civilizations of Mars were destroyed or went into hiding!?
Why SciShow thumb?
HAAAAAAANK
Smh 🤦♂️ seriously?
It’s because the gravity pulls all the dirt down to the south…
Big NASA be spreading misinformation again 😔
Why are you guys not pbs
Plot twist, the northern hemisphere had a planetary annihilation device explode destroying all civilization on the planet in a galactic war between ancient Martians and another alien race, the millions of years that have since past has removed all evidence. Only DNA samples sent in a pod sent to Earth survived, we’re all descended from Martians.
/s
It’s probably a result of the war between the green and the white martians.
This is big news! Also it reminds me of the features on this side of the moon! Would both fenomena be related???
the doom slayer was on the north pole when he sneezed for the first time.
erm .. discreetly witty
nice 👋

*Mars’ not Mars’s.
Most Rocky planets have a version of the Rolling Stones.
It just occurred to me… could we drill into the mantle of Mars?!? We primarily stopped trying on earth because the rock started behaving more like plastics due to high temperatures, so with Mars being much cooler…. maybe someday?
Isn’t “Martian geology” a contradiction? Geology is the science of the earth’s topography… geo means earth.
If the southern highlands were made from massive amounts of lava, does that mean there should be hollow chambers under Mars’ surface?
Mars is the Roman counterpart of the Greek god Ares, the god of war. (He who lives by the can opener, dies by the can opener).
I wonder if the timing and masses would work out such that the Pluto sized object could have glanced off of Mars then impacted the Earth forming the moon. But I would imagine if the numbers worked out for that it would have been mentioned. If I had to guess, I’d say the timing wouldn’t work out as the collision that formed the moon was very early in the history of the Solar System.
Silly human, the forerunners planetary engineering failed. Mars and Venus were supposed to form another Earth / Moon double planet, but they missed..sigh…the best laid scheme of things..indescribable. Geoff Who read way too much Science Fiction in his youth. ;->
Throw some gorillas at it
Uh oh, got a new band name up for grabs. Please welcome, Martian Crustal Dichotomy. Opening for Coronal Mass Ejection, which actually is a real band, but they got sued because the name was apparently already taken,but the ones with the rights to the name, are truly undeserving in comparison when you listen to the band now regrettably known as Luminance. Which just sucks imo, but at least they got to name their first album CME.
“Mars’s”
Great video!
Yesssss
The north is going to be where there will be oceans on mars. *a single tear come out on one eye as country music plays in the back*
Engaging comment
You made this video because of Atlas Pro didn’t you? Anyone interested should check out his video on the subject, it goes much more in depth.
Nuclear weapons
So should we set a colony up in the north or south?
Call me stupid, but could just be where the ocean formed?
I’m curious as to why an oblique impact to Mars wouldn’t leave a crinkle or folds along the edge of the impact. Was ancient Martian geology deformable in that way?
Maybe mars collided with something, shearing off that area leaving it more prone to eruption. Then over hundreds of millions of years the planet rounded back out.. Maybe that’s why it has so many moons =)
What if the moon touched mars
What about the asteroid belt. Supposedly now a destroyed planet/s? How about Ceres in that same belt?
What about…. Martian Pangea? The planet just cooled too quickly for it to break up?
Lot could be from liquid water seasonal melting. But also bacteria plants animals greatly affected geology.
If. The sea&river beds gullies sendiments were billions of years old would they still be around and at rate of losing its atmosphere how far back in time before it gets thick .
I found calculations.
Maybe Earth is messed up and Mars is actually normal? We do seem to base our judgment on where we live.
Could a big enough asteroid hit the planet to cause the core to be displaced , where in the core is thrust to one side acting like the clapper of a bell.
Olympus munns cooled it way faster then they think i bet ,.
Northern half of the planet was an ocean
Hey wait is hank green and joe hanson different?
If the sea& River beds gullies and sendiments were billions of years old would they still be around.
At rate mars is losing it’s atmosphere how far back in time before it gets thick
So basically, Mars is weird? 😁
Giant impacts cause antipodal mantle plumes.
Fascinating!!
How long does it take for the poles to flip? I don’t mean how long between the poles flipping, but rather how long does the “flip event” take to complete.
Mar’s Southern hemisphere is thiccc
Our moon is roughly the size of Pluto…
Neat video! Thanks for uploading!
This is so cool!
Hank looks tan ;D
There are only 3 rocky planets that are close enough for us to have examined (we don’t really know anything about the surface of Venus thanks to its thick probe-destroying atmosphere.) I mean technically 2/3 counts as “most” but it still seems a bit of a stretch of terminology.
Maybe that possible collision was a bounce instead of a permanent collision. And one of the moons is the captured culprit?
I thought “The Martian Dichotomy” was the question about whether or not there were Martians on Mars 😞
How might this collision and the collision that we believe formed earth’s moon compare? What if, hypothetically, Mars hit earth at low speed and the moon was formed?
I love the word *smooth* it’s so…smoooth
wow, so the scientific establishment DOES know about Mars’ direct destruction of the ancient alien planet Tiamat… they just call it something else 👀
I feel ya Mars.. I had a crustal issue in high school.. it gets better. Hang in there.
Perhaps the erupting volcano, near the south pole, can help explain how Mars was warm in its early years? I don’t know; just a thought.
I think Earth’s hemispheres are also very different: the northern has most of the land, with almost 90% of the population as a consequence, while the southern is mostly ocean. this affects the heat distribution and the seasons in each hemisphere.
Mars was actually larger or might have been if vaporizer. Sulfur hydrogen bonds .
Carbon nitrogen bonds into the atmosphere that planetary material would blow away with the rest of the atmosphere. Plus how much of the earths gravity. Is water how much of earths geologic activity is driven by ocean Subduction
Every time I look at SciShow Space subscription number, I feel like there are way too few people who are interested in science and space.
Perhaps that explains why there might be more subscribers to Flat Earth theories and such.
It’s sad to see only 1.32M people on Earth that believes the earth is not flat, and not perfectly spherical either.
We told him he couldn’t just shoot a hole into the surface of Mars… He clearly didn’t listen
We had a map of Mars up for a long time, and I always found it amusing how the highest point was in the northern hemisphere and the lowest point was in the southern, at direct contrast to the averages of the two.
4:05 other than earth moon… lol
It’s great to watch videos that teach and inspire. Most of what I see these days is political and angry.
“Magma from the Martian mantle” is a splendid piece of alliteration.
Where’s Reed been lately? I’m starting to get worried about him….
“martian geology”? wouldn’t that be areology instead?
The geological differences between the northern and southern Martian hemispheres are a plot point in the Martian Trilogy beginning with Red Mars by Kim Stanley Robinson! If you’re into hard science fiction set on Mars with a political/sociological/psychological bent, then I highly recommend checking it out. Robinson’s descriptions of the Martian landscape are truly beautiful and get across how this barren, dead, alien landscape might also have some intrinsic value as it is now.
Nothing large enough hanging around mars……….
Phobos: WHAT ABOUT ME
If you found this interesting, you should watch a video made by Atlas Pro, about the geography of Mars. Very interesting watch.
Edit,: spelling
Solved: Mars is actually two half-planets glued together.
Mars: *minding its own business*
Pluto’s angry cousin: “I’m about to smooth this man’s whole career…”
“there aren’t any rogue pluto sized objects around mars these days” *eyes phobos & deimos’s orbits suspiciously*
I wonder if a moon de-orbiting is in the right speed range.
Perhaps not quite so extreme, but note that both Earth and the Moon have similar large-scale crustal asymmetries. With Earth, it’s the Pacific Ocean as a whole. With the Moon, note that all the maria are on the Earth-facing side. The far side is much more heavily and uniformly cratered.
it’s nice to see a resurgence in geophysics and mantal crust convection studies.. keep up the terribly fascinating work fellow humans
