Hi everyone, Alex here, welcome to the remaster of the video that made this channel possible! It was my first ever video to take off. I've come a long way since then, and wanted to revisit this amazing planet with updated visuals and audio. I just wanted to say thank you to everyone who joined Patreon. Your membership is what allows me to keep Astrum what it is, and not what the algorithm looks for. bit.ly/4anEb5u

[@Abcdefghlll708]

3days how?

[@phloxie]

Cool video thanks ♥ it but why does mars have so much xenon-129? always wondered about that :o

[@alexneff]

Hi Alex, Alex here love your work thank you you have put me to sleep many nights and kept me up many more

[@HypnoPol1499]

Love it and love your voice. So helpful with anxiety. Thank you.

[@JHorkan]

I watched that again a couple of nights ago. Must have watched it dozens of times now.

[@Ericaodd]

Did you have to re-upload this because the preview bots thought Olympus Mons was a nipple?

[@dew12u]

Only reason I clicked on it.

[@cosmolosys]

I came for the boobies. I thought it was an ornithology video 😉

[@alexneff]

Hahahah likely

[@tjallingdalheuvel126]

I have a theory on how the Milkyway came into existence now.

[@drgonzo123]

Whenever I think of how Earth looks to other planets, I think of Carl Sagan’s “pale blue dot” quote, and everything in my life feels so small and meaningless. Instead of feeling depressed or horrified, it calms me, and helps me distress a little just knowing how insignificant we are in the grand scheme of the universe.

[@Ciacien-ke7ot]

i think you meant "destress" lol the only reason i bring it up is because "distress" means literally the opposite of what you're trying to convey 😂

[@ioanwib]

The grand scale of the universe makes me reflect back on what we call life in utter amazement, it really is a miracle. It makes me want to work for a better future to uphold this mantle of life. And maybe one day we'll be lucky enough to see it touch the stars.

[@robertnewhart3547]

Fact. Lol

[@MadHax-wt5tl]

Many years ago a friend of mine got himself a telescope. When he first trained it on Mars, the planet was experiencing a global sand storm. He described it as an orange fuzz ball. We both got better views later, and could make out features like the polar ice cap. I'm totally glad I got that opportunity.

[@cristinelcostachescu9585]

The only thing I regret while watching your videos is not having a 70" 8K TV, and a surround audio system. Man, what an experience your videos would be.... Great work, as always, Astrum!

[@Car_guy31]

I took your advise and got off the iPad, turned on the TV (55" qhd+, 4k, cuz that's all I have) and got my Sony XM1000 headphones on (late at night for surround speakers). Made a HUGE difference to the experience..❤ Thanks.

[@JusNoBS420]

Thank you Astrum team!! The way you communicate astronomy is second to none! And I'm sure many enjoy the podcast but wish it were longer lol. I personally use it while I drift off to sleep. And the soft music you play at the end of the cast is perfect 👍

[@d-boyzinfinity1614]

Love the remasters for this series. We know so much more than we did back then and it gives you a chance to make a video of higher quality. I’m pretty new to this channel but it’s become one of my favorites and I’ve gone back and watched your older videos, especially about stars. I find stars and light to be very fascinating. It’s amazing too the images we can get now from Hubble, modern ground telescopes, rovers, and probes. We can see the wonders from space from our own little neighborhood here around the sun all the back to the distant past of the universe. There’s so much beauty on this planet that it’s a marvel to see the beautiful features of places we most likely won’t get the opportunity to go to. Keep up the good work

[@Beryllahawk]

Mars will always be near and dear to me. The landing of the Pathfinder/Sojourner mission was a big part of my first date with my now-husband, and sometimes I go back and look at the little collage I made - this was the 90s, it must have taken me hours to find and print out two dozen different images of the rover and of Mars. Good times! I'll always be fascinated by this planet and your videos in particular have been a joy for me. Whatever you choose to remaster next, I'm here for it!

[@CasuallyCold]

<a href="#" class="seekto" data-time="708">11:48</a> That particular Dust Devil was about the same height as an average tornado here on Earth which they can get over a mile tall or 1.609344 Kilometers.

[@MadHax-wt5tl]

And I'd rather get hit by the Martian tornado, as the low air pressure would make it no stronger than a slight breeze. But I'm guessing we all knew that already..

[@CasuallyCold]

Yeah. & I think due to the low air pressure I think the dust devils want really to pick up stuff beside small dust particles.

[@robinson-foundry]

Yes!! I've been waiting for this for years!

[@paulspaws1521]

I love your channel, I love the videos, the information and your voice the words of presentation. It is so fascinating. Every video ist a work of art in science.

[@ParrishRobbins]

Thanks Alex. Happy to see all your video's on solar system bodies remastered.

[@StretfordEndGaz]

im 52 and i dont think i have 20 years left in me, i do hope in my lifetime i see human on mars seeing how space exploration has moved along in my life, seeing mankind land on mars would be the pinnacle

[@badram0204]

I'm in the same boat, im 57 , where has the time gone. If anyone can do it it's ELON MUSK

[@heinrichagrippa5681]

Damn, not making it to 72? That's kind of grim. Or at least it seems that way to me, as my dad actually _is_ 72, is more physically in shape than I am despite being a little over twice my age, and it doesn't seem like his health is going to fail any time soon. Hell, his _mom_ is still alive and will be turning *103* in November. So I hope you were just being pessimistic and that outlook is not due to an actual medical condition.

[@StretfordEndGaz]

[@liisabjork76]

Just beautiful and fascinating. I love everything about space. So cool that i was in that photo!

[@mikezizis3725]

Thank you so much Alex! Your presentations are always wonderful and your enthusiasm is infectious. I need to mention a fact that is never covered in the presentations of Mars in anyone's video but is truly astonishing. There is so much water on Mars that if the surface water was melted including the hidden glaciers it would comprise an ocean of about hundred and 15 feet deep over the entire planet. Could you please and a feature video give this theme sometime? From Wikipedia:A bundant water ice is also present beneath the permanent carbon dioxide ice cap at the Martian south pole. More than 5 million km3 of ice have been detected at or near the surface of Mars, enough to cover the whole planet to a depth of 35 meters (115 ft).[13] Even more ice might be locked away in the deep subsurface.

[@damianpokarier2965]

My favourite Mars fact: we're yet to visit in person. We live in very exciting days

[@stuarttunstead6616]

[@tonyjohnson8929]

My favorite fact, which I just learned, thanks Alex, is the reason Mars has that color. It also got my imagination zooming thinking about the megastructures that had to have been there to create that much rust. The Fe was mined from that used to be Grand Canyon size, crevasse Valles Marineris. That's where all the oxygen hiding. When we go back and start building again, more iron we use, easier it'll be to breathe. Now that's one helluvan incentive right there. Lol

I did not know that Mars had a tilt... and therefore seasons. Thank you for sharing this.

[@Penfold101]

It does have a tit apparently.

[@bimblinghill]

It does, but also, unlike Earth, the eccentricity of its orbit also has a big effect. These add together to make the southern hemisphere have much more extreme seasons.
