Absolutely fascinating video. Thank you for your work preparing this. Wish I could be some cyber type man and just explore these places on foot. Some extraordinary bizarre landscapes. Mars is an amazing place.
As it’s the deepest part of Mars, would that be where the Martian atmosphere would be thickest? That would be a point in its favour to be the first colony site, maybe?
The atmosphere is indeed the thickest at this point. A research colony site could possibly be set up at more interesting parts of Mars but this looks like the best place to set up a semi permanent base.
But if one of the initial goals is to increase Mars pressure ~6x this location may often be just above the Armstrong Limit making it more survivable in the event of unexpected depressurization, which I personally believe is the most important variable. So long as you dress warm, practice your breath hold and/or carry a mini Spare Air bottle then emergencies should go from being catastrophic to inconveniences. Add in an orbiting centrifuge station for 6 month rotations and limit unshielded radiation exposure to 8 hours a day and this Mars thing just might work. Really hope they pick the lowest point on Mars for the colony so long as ice is nearby
Great video just one error at 5:18 the space probe that you are referring to is not 60 years old its only around 18 years old launched in 2005 called mars reconnaissance orbiter
It would get old very quickly. What the hell do you do in Mars? Can't go anywhere, can't travel, zero infrastructures, all alone, trapped in a small base... To live there must be a nightmare.
@@kerolokerokeroloinitially agreed but once you got multiple large domes interconnected. As well vast underground City's won't feel small but being able to walk down see the ocean I get you
I had wondered about Mars colonies being established in deeper areas, where the atmosphere was thicker and more stable and would provide more protection from Solar radiation. I was wrong about here. Being deeper and with a thicker atmosphere, but with greater surface area, means more air movement and more dust storms, the opposite you would want for a colony. Thanks for showing me that! Marnier Valley is still in the running though.
Hellas is huge and very deep. Generally speaking, Valles Marineris is also 7km/4mi deep. Another way to say atmospheric pressure of 1200 Pascals is that it is 12 millibars or 0.174 pounds per square inch. That means Earth's atmospheric pressure is 84.5 times greater than even the Hellas Basin.
Yes, I wonder if this area was filled with water, like a little south ocean, separate from the giant one in the northern hemisphere, or had it been just a giant crater depression during mars’ liquid water days. now if mars had pressure just like ours in the old days to sustain water on surface (which evidently it had), the deep craters and depression were probably roasting maybe even 40 or 50 degrees if we think mars had mild climate, lets say average 5 or 10 degrees (celsius I mean, Idk Farenheits srry😊)
It's kind of crazy when you think about it but just about damn near everyone, past and present, has been drawn to Mars in some way or another; Some people are just fascinated with the planet whereas others literally yearn to step foot on it despite how unrealistic that may be.
Was it an asteroid that caused such a large crater? I wonder if maybe once Mars had some form of plant life and what caused Hellas crater killed everything.
Very good, informative video with nice graphics. Since I am a researcher and Mars is my specialty, let me assist you with the pronunciation of "Planitia". It is pronounced with the "SH" sound like this: Plan-ish-uh. Keep up the good work.
Is it true that transient liquid water flows might persist in the depths of Hellas Planitia? It's a tantalising prospect but it's not something I can find much information about. From what I understand, at 1200pa the boiling point of water is roughly -21°C, and the average temperature on the western side of the crater is roughly -45°C on average. The conditions might be ideal at certain times of the year for liquid water or brines to exist on the surface, no?
So on Earth the pressure at 20 000 m are 5475 Pa and in that deep crater on Mars 1200 Pa - I assume some life might or might be possible in that crater if there is oxygen down there in the soil -Why not examine this in chamber on earth whats possible.
Thanks for covering this, finally a nice little video about this intriguing hole that we always see but not know much about, Im actually surprised that scientists dont really seem to be interested in the deepest parts of the planet, it would be super cool to measure that higher pressure and to see if the terrain is any different under such. probably wind is stronger there and weather in general is more extreme in such depts, maybe it would be risky to send an expensive rover there, but still, dang id love to see a probe in both Hellas Planitia and famous Valles Marineris, like, a freakin glacier is there, how cool is that?!
What are we supposed to do? Use the native martian name? And if you think mars is bad, wait til you hear what they let the nerds name all the stuff on Pluto.
Gravity is too low to compare it to Earth, Venus mountains would be comparable... We really need to send a giant robot over there to do some proper digging around, literally with wrecking balls for testicles.

I wish elon musk woud land there, IT might sound pointles at first but you get more temperature and double of pressure compering it to normal one at mars, i think it woud be great place for marsian base
I've always wanted someone to speak about Hellas Planitia in entire mini documentary form. My wish became true.
I think hellas means Greece? Because in greek we say Ελλάδα(Hellas)or Ελλάς(hellas) which is the same.
Or you might've heard the word "Hellenic"(Ελληνικό)
Το put it in another way Hellenic(Ελληνικό) means Greek(Ελληνικό)

Another video, so fast as well. Keep up the great work; you're my favorite astronomy channel!
Another video in 2 weeks! Glad you’re still going strong
I watched this video last night and the wait was worth it.
Your content is amazing 😳
You're always so well spoken. Thank you for another fascinating video sir.
I like the eerie but peaceful music in the background of every video. Helps me fall asleep.
Great video man, I would love to see more of these in depth looks are specific regions.
Some seriously powerful things happened on Mars it seems. Great filter level events Im guessing. Great video
Best way to end a Friday!
Too bad that I can’t wait to watch this tonight. I’ve been waiting too long.
Absolutely
As it’s the deepest part of Mars, would that be where the Martian atmosphere would be thickest? That would be a point in its favour to be the first colony site, maybe?
I made the comment before watching the video….. lol…..my question was mostly answered during the first few seconds…
The atmosphere is indeed the thickest at this point. A research colony site could possibly be set up at more interesting parts of Mars but this looks like the best place to set up a semi permanent base.
"Thickest," by Mars standards, which isn't very much. And still multiple times below the Armstrong Limit.
But if one of the initial goals is to increase Mars pressure ~6x this location may often be just above the Armstrong Limit making it more survivable in the event of unexpected depressurization, which I personally believe is the most important variable. So long as you dress warm, practice your breath hold and/or carry a mini Spare Air bottle then emergencies should go from being catastrophic to inconveniences.

Um yes.
SpaceX needs a landing site in Hellas Planitia.
YOU’RE BACK!
He… uploaded 13 days ago… chill man.
I definitely needed this today. ✌🏻

So good
Amazing vid. Can't wait for humans to get to Mars. Imagine standing in one of these long valleys, the view must be amazing.
We would be dead by then:(
I understand, I frequently go there in Space Engine just to dream :)

Works so beautiful with the music from Prometeus

A great documentary ! 🧡🧡🧡
Thanks for another great video
Amazing tours of the Martian surface.
Interesting upload 👌🔭
I love this channel so much
Excellent Video. Hellas deserves a rover.
Could this be Phobos and Deimos that we see now ?
Hey drek 👍
Thank you derkler for another great video!
thank you for your work!
Good stuff.
Thousand times my favorite video❤❤❤❤❤❤
happy new year
Happy Friday dreksler astral
Good work
The very best place on Mars to find liquid water is in the Hellas Basin in summertime.
thanks for the content :D
Awesome vídeo !!!! 👍🏻👍🏻👍🏻

Real question is how do we dome over entire hellas region (para terraforming) for what likely become future site of the great hellas ocean
@@thomas.parnell7365Less of an ocean, more of a lake. A sea at best.
Amazing video with great information, thanks;)
Is Hellas Planidia a good place for a human colony? Or would Vallis Marineras be better?
If you watch star trek from TNG onwards you will hear the correct pronounceation of the wotk planitia/ {rpnounced Planishiuj.
Seems as mars could have had life at some point but was bombarded by continent sized meteorites so it had no chance
That crater could contain the building blocks of life.
Which means a habitable dream for us all❤🎉
Cool 😎 👍
Great
So on Earth the pressure at 20 000 m are 5475 Pa and in that deep crater on Mars 1200 Pa - I assume some life might or might be possible in that crater if there is oxygen down there in the soil -Why not examine this in chamber on earth whats possible.
Great to see the appreciation of Greek culture on earth being extended to mars

Video idea. What if venus had no/less clouds
ELLAS the land of light
every video is about balls in a different size and color basicly 😁😁😁
Every crater a direct hit, no directional debris fields. What are the odds on that? Electric Universe Theory.
Some lake been there
Wow
6:18.. "Alien Covenant" kinda cool twisted rock things..😅
It is somewhat more commonly pronounced Hellas "Plan ee sheeah".
😎
Wish we had a good topographic map of mars.
pronounced Planishia..... poor Dreksler 😉
A better image of badwater crater would be well worth getting
Earthly humans naming everything in the universe whatever they want it named 🤦🏾♂️
What are we supposed to do? Use the native martian name?
And if you think mars is bad, wait til you hear what they let the nerds name all the stuff on Pluto.
Must have been the location of the ancient impact that decimated the planet. Look how huge that is.
There’s a theory that the northern hemisphere of mars is lower than the southern is because it’s actually a colossal impact crater.
Yes, definitely looks like a hit.
i just cant wait for us to send someone out on mars and see the complete nothingness 😆
Gravity is too low to compare it to Earth, Venus mountains would be comparable...
We really need to send a giant robot over there to do some proper digging around, literally with wrecking balls for testicles.

I couldn't get past the pronunciation, sorry. It's Pla NEE shuh, not Pla NIT EE UH.
tomato tomato
Well, the correct Latin pronunciation is PLA - NI - TI - A, so exactly how it's written.
hes also from somewhere in eastern europe
@@tysonwastaken I think he pronounced it correctly.
Hellas, Phobos, and Demos. Mars has a distinct Greek culture 😅
