There’s hardly any atmosphere left on Mars to terraform. Practically a whole new atmosphere would have to be taken there and released just to bring up the pressure. And with no magnetic field, that new atmosphere won’t last.
ОтветитьIt would be difficult to walk on an Earth 5 to 6 times more mass. Any life there would be highly compact.
Ответитьwatching Fraser reminds why 'journalism' is actually a profession, not a swearing word
ОтветитьHow many Trappist-1 exoplanets in habitable zone are also in ultraviolet habitable zone?
ОтветитьGreat explanations. I subscribed and hope you return the favor.
ОтветитьPeople who still believe in outerspace nonsense are lost never to be found.
ОтветитьSpoiler: no
ОтветитьMars has almost no electro magnetic field. Any atmosphere we could create there would be blown off fairly quickly by the solar wind, which is likely how Mars came to be as it is today.
ОтветитьWe will NEVER terraform Mars let alone any planet. Imagine how freaking stupid it would be to spend tons of resources terraforming a planet when you could just build three paradise stations.
Terraforming is becoming more over used then gaslighting
Is the creation of the maldives rising sea level
ОтветитьDoes the regolith on Mars resemble that of the moon closer to the surface and earth farther down since it had water farther back in time?
ОтветитьAbout the eyeball planet, your numbers are false : if the density is 20% less, then the size and mass compared to earth's can't be 1.7 times and 5.6 times. One of these 3 numbers is false.
BTW, with 1.7 and 5.6, this gives a gravity of almost 2 times that of the Earth (1.94) and the density would be 14% more than that of Earth.
Ultraviolet does not wear down ozone. Ultraviolet creates ozone. It splits the o2 in the atmosphere into o. That's why ozone measurements can only be taken over the poles in winter time because new o2 is not being produced there.
ОтветитьH2S is astonishigly lethal, don't go there
ОтветитьTeraforming Mars can never happen. It has no magnetic field. It's not even science fiction. It's just fiction.
ОтветитьPeople cant even get along on Earth nor can most farm or garden. Yet our hubris allows us to think we can GOD over other planets. Fkn hilarious
ОтветитьGood job recommending Anton/adding the link below. What goes around, comes around.
ОтветитьSo, when you say "Super-Earth," does that mean that the people who live on that planet are like Superman and that they all have the same list of super powers and abilities?
Ps: That's obviously a joke. Or it should be obvious...
Moss on Mars. Martian Moss. Mars Moss. There's a good product name here somewhere. Or a band name, whichever.
ОтветитьCan you start talking about a real more important topic called UAP that 60 plus percent the world's population knows are real and can only be explained as a non human intelligence and technology, please address this More and save yourself from being laughed at throughout history as another moron like Niel degrass Tyson, Mick West, Anton Petrov these wannabe scientist that cannot accept the most obvious and profound truth that were not alone , were being visited by a non human intelligence or future humans whatever, stop being stupid, stop searching for life when the proof is here that most common sense people can accept but your bias wannabe cool science is dumb
ОтветитьWill the ice shell of an eye-ball planet drift as the ice shell of Europa?
ОтветитьAs far as reusability and lower cost, as far as I know it costs the same money to reuse an F9 whether it's used once or 9 times, it's not like the price is down to 10 million for launch, so maybe not is so reusable. Idk maybe Fraser now more about that
ОтветитьQuestion: How do large hydrogen plants form. Do they need to have enough mass first to capture hydrogen? ie does Jupiter have a solid core?
ОтветитьI expect most launch customers care about whether a rocket gets their stuff where they want it and how much they pay, not how many times the vehicle has been used or whether it will be used again.
ОтветитьTidal locked exoplanets, although great for resources, and research. But I imagine we'd want something more earthy even if shorter or longer days, weeks years. Or even slightly different gravity, and atmosphere pressure.
But we'll definitely want the best for a second backup human home planet.
If we could somehow genetically edit these moss characteristics into edible food (or make an edible, coca like, version of this moss) (or biofuel producing plants) it would make farming on mars A LOT easier. You could depressurize the crops and repressurize them without killing the plants.
ОтветитьIs a world only made of water possible ? like a giant drop of water, no solid core. i think so.
ОтветитьOn reusable rockets the old Sea Dragon design from the 1960s should be taken into serious consideration. It would be a behemoth of a rocket, 490' tall by 75' wide. It would be capable of lifting 500 tons of payload into low Earth orbit for approximately $500 a pound.
It's simplicity would make it extremely reliable and its re-usability make it low cost.
Yummy information on a plant to terraform Mars. Wonderful. I'm already gathering information for a 2nd edition to my own book, Terraforming Mars: Remaking the Red Planet, Ready for Life. The book is only in hardcover at the moment, but there are plans for paperback and ebook formats. Of course these will come before a 2nd edition.

Looking for life on Proxima Centauri b is like searching for gold in a garbage dump! If life is common throughout the universe (and there is mounting evidence that it's impossibly rare), then all you are likely to find in the Proxima sub-system (of the Alpha Centauri, 3-star system) are microbes struggling to survive near the terminator of that tidally-locked world.
Whoop-ti-doo! Interesting to a xeno-biologist, but most people would merely yawn and shake their heads at the obtuse nature of such a discovery. I'd be thrilled to find the Klingon home world or Vulcans, or some non-fictional counterpart to them. But microbes? Sheesh!

Excellent up to 3m 55s. The notion that UV is needed for genetic variability to drive evolution is logically hogwash! I know this channel thrives on science and logic, but the "random mutation" model for evolution is perhaps the worst idea currently held by some scientists (perhaps in a feeble attempt to bolster their views on religion and spirituality which should NOT be a part of the logical calculus).
Imagine, if you will, a tiny island of viability where life thrives. Surrounding that island is a vast ocean of chaos where life is impossible. There are other islands, to be sure, but the distance between them is HUGE!
This is like using a random number generator to scramble the letters in a sentence. It doesn't take long before the sentence becomes garbage. And there is a lot more potential garbage than readable text from that point on.
Scrambling the "letters" of genetic code with random mutation from radiation (like UV) would far more likely produce death than life.
Molecular biologist, Douglas Axe, found that, "for every DNA sequence that generates a functional protein of just 150 amino acids in length, there are 10^77 amino acid Arrangements that will not fold into a stable three-dimensional protein structure capable of performing that biological function."
To put this fact into perspective, I remember reading that there are only 10^65 atoms contained in the Milky Way galaxy. And if the Milky Way is an average galaxy, then it would take 10^12 (one trillion) galaxies to contain 10^77 atoms. Are there even that many galaxies in the universe? I've heard estimates of billions, not trillions. So, it would be like looking for the one atom in our universe that would work, while ALL the others wouldn't.

MUST MOSSIFY MARS
ОтветитьAnton was mentioned, I am happy
ОтветитьIs the the current fuel to payload ratio of Starship good enough?
ОтветитьOkay, I'll say it: "Mars already has seasonal moss/lichen that can live there. Photos of it were released years ago." Honestly, for the last 40 years, the "space science organizations" have designed missions and done everything else they can to not-quite-yet discover life on mars, trying to creep up on it like Zeno's Paradox without actually being forced to confirm the Viking results. It's a combination of pride and economics.
Everyone wants to be the one to "finally" discover some kind of life on mars, but in their own name, not just confirming decades past that will give primary credit to someone else. Also, as long as they can dangle the bait of not-quite-yet discovering life, they can keep getting funding for everything that approaches it asymptotically, counting on governments to forget how easily the question could be answered after all. In both cases - ego and money - it's all about human politics, not about maximum revelation of the truth.
Well, you're gonna find out in about 10 years anyway, because SpaceX is going to do the politically incorrect thing and just send people there to look around and set up shop anyway. In their viewpoint "We don't care about Zeno's Politics, and we're not waiting a century for bureaucrats to play out the long con. We're just going on our own budget, so eat our dust."
You're welcome. If the powers-that-be in science/government funding don't like that post, they don't have to talk to me, nor give me ten billion dollars to not-quite-yet discover life on mars again. I guess I'm the cheaper alternative, but I'll remind you all of it if I'm still around for another decade :)
What would interest me is whether Syntrichia caninervis could grow along Mars' equator already now, during the phases of temperatures above the freezing point of water which occur there. For if this works, then one could perhaps use the moss already in the first period of a Martian outpost for the sake of reigning in the dust problem. I'd also love to hear more about how the scientists who consider the moss as potentially capable to survive on Mars have mimicked Martian conditions.
ОтветитьThe fastest way to terraform Mars is to build orbital habitats all over the solar system and let future tedium seekers mess with it. You know they will. We have nothing to contribute to the project except getting busy turning asteroids into I-beams already.
ОтветитьI am leaning in the belief that Earth is a one-off situation, and that we may be alone in the universe, which could be good for us. Makes this galaxy ours and eventually the universe. If we don’t eradicate ourselves, where will we be in a million years as an ancient civilization?
ОтветитьIt's pronounced Ari-Anne.
ОтветитьMars seem to be world for non biological life forms (= ?).
Maybe next evolutionary step to AI life forms?
So no plant life, no water, no oxygen atmosphere.
Can we detect magnetic fields around planets like Eyeball?
ОтветитьWe are NEVER EVER going to terraform Mars. It will NEVER HAPPEN.
ОтветитьWhat's the best software for exploring space? There used to be Google Sky, which did with telescope images & the celestial sphere what Google Earth does with satellite imagery and Earth's surface. It was awesome and had labels and constellation overlays, but it's been discontinued. I've found Celestia also good for exploring the Solar System and nearby stars and galaxies.
ОтветитьIs it possible that those high velocity stars are just passing by that cluster? Feels like just going by their speed is a limited evidence... Unless they seem to follow an orbit within that cluster.
ОтветитьPlease can we stop using the completely oversaturated and irritating "wow" sound fx that everyone plasters across their videos - we've heard it enough.
ОтветитьBasically, run!
ОтветитьTerraforming Mars is an incredibly stupid idea, and people who disagree need to go back to school. We live on Earth. Why terraform Mars when that tech could get Earth balanced first?
ОтветитьI don't think Ariane or ESA wants to do reusable just yet, as their low launch cadence in combination with reusable systems would mean less work to be done for everyone involved in between missions? Keeping the suppliers supplying and workers working, maintaining a healthy sector and expertise, seem to me to be the main benefit of the whole Ariane program. I could be wrong, and I am definitely a junior arguing the experts on this. Great video as usual, Fraser!
