You know the human race has its priorities mixed up when a video of a cat walking into a glass door gets billion views, and something like this only gets a few thousand
I learned from this lecture that Mars was habitable at least for one hundred million years to as long as a billion years. What was not mentioned was that they were referencing Mars surface habitability, that after one hundred million to a billion years of Mars surface life, the surface life had to move underground to compensate for the dropping atmospheric pressure so that the theory is that Mars surface life evolved into Mars underground life and now resides 10 meters to a kilometer and more below the surface where it is thriving and releasing methane gas up through vents into the atmosphere.
Or came to earth. If an extraterrestrial species does exist. It’s much more likely they arrived on earth from either Venus or Mars a billion years ago versus having to tackle FTL travel and find us through interstellar space.
"Good evening everyone, my name is Andrew Fraknoi" - is there a better phrase to start a youtube evening? This is one of my all-time favorite lecture series.
So thankful, every Video posted full of fantastic information and especially after studies when bed calls my favorite relaxation background...my saying: When your online and your not learning something, it's a waste of time...
610 pa is nearly the triple point of water, which at 0.01 degrees C is actually 611.73 pa, so there could well be water in a valley or similar. And if this is true, then there must be life EVERYWHERE in the universe, which means that alien visitation must occur all of the time. Which means that the reason there is not missing link is because there never was one and we could've been genetically engineered by dolphin people who visited the Dogons ( or something like that.)
Very interesting lecture, thank you! I wonder if the samples of atmosphere from the meteorites can show some evolution in the martian atmosphere from more lighter isotopes earlier to the more heavy isotopes now with Curiosity?
Are those photos realistic 1:1 reproductions of the planet in it's true color scheme and brightness or have they been altered? I've read once that this is a common thing to do and I think it shouldn't be done because you want to know how the planet actually looks like.
They typically do that with photos of objects in space, but not with planetary images. Sometimes they do it to overlay various EM spectra on top of one another to show the different wavelengths of light and how they'd all look together, other times to falsely spruce up said image, which is kinda lame. "They" being amateur astronomers more often than not.
Much was lost to space but there is still a vast quantity there: "More than 21 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).[12] Even more ice is likely to be locked away in the deep subsurface."
I saw a fossil foot/hand next to a rover on google earth. Tried again to find it next day because I wanted proof and it was gone. I can describe it as a crocodiles foot or some dino foot. If someone finds it pls message me.
Wasn't Mars much closer to a much smaller sun and when Jupiter migrated outwards Mars followed outward at the same time the sun grew hotter -So wouldnt mars have been warmer or colder back then or about the same as today.
If Jupiter was so much closer as the asteroid belt wouldnt the gravity and sun start to make some gravital heating like on Io -a sligth anyway every few years.
mars was never like earth venus is where it all started, when sun was younger, smaller, and less strong, mars is in the process of being terraformed, not by humans, but because sun is growing, earth will replace venus, and mars will then replace earth, million years later
Can an artificial magneto sphere be invented to help teraform Mars?? What would be the first steps in reaffirming Mars? Humanity's future may depend on crazy ideas. I point to Isaac Asimov 's satellites. What about Venus??

Thank you *so* much for sharing this with those of us who can't be there in person.
2:43 is when it starts.
But our consciences won't let us skip Andrew.
Loved Dr. Ashwin Vasavada's passion and energy.

You're an idiot.

That laser joke was funny
I always think ive already seen this lecture based on Andrews introduction lol.
Andrew does need to change up his intro..lol.love the series
Lmao
Thank you so much for sharing.
Great to hear the latest news from the mission. And presented with such passion.
If they can make the Mar's Rover near indestructible why the hell can't they make a decent car that won't break down so much?
Thank you.

Great content
Nice one, thanks SVA

What a great talk.
Indeed.
Nothern California? You mean Vancouver?
Let's everybody give a big shout out to Bill Nye the Science Guy at 32:13 .......He's everywhere ........
What technology is used to remotely control the Curiosity Rover over the many millions of miles?
58:00 Mudcracks!, But no mud footsteps...(?)
50:00- what is that big round hole or round shadow by hematite unit?? anyone? anyone? bueller? bueller?

The picture at 1:01:33 is real (as our eyes would see.)
Where did the water go ?
Much was lost to space but there is still a vast quantity there:

This guy needs to sit down with the nut Corey Goode who says 20 thousand slaves there
Why be so surprised when it works ? wasn't it supposed to work ?
If everything was done right, than it shouldn't be a surprise that it worked.
No ice dams broke , a comet struck the Greenland ice sheet and immediately flooded the N American continent
Metric system please ! :)
I thought astronomers liked to use 'attoparsecs'.

Thanks for clearing that up 👍
Jurassic Park is a movie from 1993... and now it's 2018... He's gotta start watching newer movies
Jurassic World: Fallen Kingdom (2018)? :)

Love the enthusiasm of speaker, but program would have been 15 mins less without all the uhs and ums. That said, learned many things. Thank you

Save yourself from a boring intro...start at 7:40
"Dime-sized". Ugh, freedom units.
Mars NEVER was like Earth! It's way too small to have been ANYTHING like Earth. :-))
21:16 Sure you can. You're an american.
Mars was never like earth , LMFAO how did religions enter the field of science.
how do you know? were you there?

ADHD Americans...Calm down please when talking... taKE time to breath...
Europeans with superiority complexes, either show us your Mars rover or just sit down and shut up. You MIGHT learn something.
