I'm so glad that Ms. Lynch immediately brought up the fact that Mars no longer has a magnetic field to deflect the solar wind. SO many people overlook that when bringing up the subject of terraforming Mars.

My Freshman Chemistry professor was a big fan of Perchlorate, did research on using Perchlorate Acid to transform oil shale for use. He was all about Perchlorate to the point his vanity license plate was HCLO4. Funny how things stick with you 33 years (since I was a freshman).

Kennda’s passion,enthusiasm and expertise made this episode absolutely delightful.

At first, I was very disappointed that Chuck was absent and replaced by someone completely unknown to me. I was wrong! He is perfect for this show. I laughed so hard ... and he had great questions/comments.

man that was very nice to watch. She is a very good science communicator and hope to see her more often. Also, even though it would be difficult to get and energy intensive at first, you could maybe build up a large pile of "regolith" that has been washed with water that is then later evaporated to get the perchloriates out. it should at least great reduce the concentrations.

I'm glad Kennda brought up the most difficult hurdle in colonizing Mars, and that's the lack of magnetic field. Mars' iron core stopped spinning long ago leaving the planet open to the Sun's radiation. Really great conversation overall.

On the perchlorate problem: Dechloromonas and Azospira are Dissimilatory (Per)chlorate-Reducing Bacteria (DPRB) which grow by the anaerobic reductive dissimilation of (per)chlorate - perchlorate and chlorate (ClO3−) - into chloride and oxygen.

Great episode. FYI, I used to listen to the StarTalk podcast but now I find myself actually watching it on youtube, so I appreciate the video editing.

She is amazing to listen to. Can’t wait for her to finish her project!!!

SHE'S PERFECT! She can't be more interesting, charming AND fun if she try. Loved her laughter and ease of explaining her field.

Soil Scientist here. Regolith is an example in which USGS terms don't match with USDA terms. USDA calls such 'regolith' accumulations as Miscellaneous Areas. Dirt is soil that is out of place, such as when it's under the nails, or behind the ears.

I would have like to learn more about the process of removing perchlorate from regolyth so that it would be possible to grow food on Mars. How difficult would that be and how would it be done?

Love Star Talk info and all its humor. Addicted. Guest's are always great. Neil's expressions are priceless at times.

This was a really fun, informative conversation. Love the guests.

WOW!I loved hearing from Kendra Lynch! Please have her back. She's wicked smart!

People should really read the Martian book. In the book it goes into way more science and accurate engineering. The movie cut ALOT out. For just one example. Watney had earth soil with earth bacteria with him on Mars for experiments that helped convert the the martian soil.. just a quick thing. The book had soooo much more in depth information. But I love the movie too.

Dr Lynch is awesome! This was both educational and entertaining.

I loved this episode ❤ Really great to hear from experts in the field. 👍🏻 Just a quick side note: It always bugs me when people only talk about the movie the Martian and not the book, which is much more complex and "accurate". For example, in the book he not only used martian regulus, but had some earth soil, which gave him lots of the microbes needed to grow plants. Of course the bad composition of mars regulus would have still been a problem,just saying that the book is better and more scientifically accurate.

Agreed! It's been while since I read the book but I definitely recall the perchlorates mentioned in the book and it was a problem Mark Watney had to fix, though I don't recall if that was in relation to growing the potatoes or just in general.

You can tell this was an exciting topic to discuss. I’m thoroughly entertained and informed! Kennda is an inspiration

On Mars, the only way to remove the Perchlorate will be by two means: 1.) Destructive Processes: Biological Reduction, Chemical Reduction, or Electrochemical Reduction. 2.) Physical Removal Processes: Anion Exchange and Membrane Filtration. Filtration is what we will use at first.

In a recent episode, Neil mentioned how we didn't make planes with the steam engine because it would have just taken too big of a steam engine to fly. Then we get the combustion engine, now we can get that much power in a small enough form factor. Exactly like this, we don't have the tech today to terraform a planet. But we're 1 key innovation away from it being possible. Not seeing this as not just as possible but inevitable (assuming we don't destroy ourselves) is short sighted imo.

It would if there's enough CO2 on Mars to keep replacing the atmosphere eroded by the solar wind. The head of the MAVEN Mars orbiter says there's not enough left after billions of years to do that. Adding asteroids with volatiles would help, but it'd be necessary to do it slowly because a huge impact would blow away the atmosphere as well.

one can only hope. On the other hand, mankind has a pretty decent understanding now about physics and we reached some hard to break barriers created by nature laws. We also have a very good idea what would be necessary to "terraform mars", which makes it pretty unlikely. Even Scifi is not coming up with new stuff it seems. There is still a lot to understand in physics, especially how all the parts work together, but the probability of surprises gets lower and lower. For example, we have a good idea now how elements work and how they are created in stars and how much energy you need and how instable they are at some point. So the assumption that we will not find an alien ship build out of unknown elements is not nearly as "wild guessed" as it would have been a 100 years ago. Just a very educated guess now, so still a guess - fingers crossed.

600 years ago Da Vinci was designing flying machines, so maybe if you asked the average uneducated person 300 years ago if it would be possible to fly then they would have said no. But today most elementary school children have a broader range of knowledge, especially about science, than most people 300 years ago. That statement is a non starter because of the level of knowledge we have today compared to then, and we pretty much have figured out how everything technically works. No matter what kind of tech we have in the future we won't be able to terraform an entire planet to make it work like Earth because no matter what that tech may become physics will still be physics.

@@robo5013 to terraform mars you need to heat it up and preferably have a magnetosphere. We already proved on earth it’s possible to pump gases into the atmosphere to heat things up (without even trying). Making a magnetosphere is the tricky part, restarting the planets dynamo core is way beyond human control, even in 300 years, however an external way of making a magnetosphere is much more likely. There have been ideas of using orbiting shields, but my my favorite idea is using Mars’s moons as a station to fire off charged particles into Martian orbit creating plasma torus that’s acts as a artificial magnetosphere. This is not out of human control, escaping the solar system may never happen. If that’s the case then humanity better push to terraform both earth and mars in the coming centuries.

@@SolarisSaber Making planet sized shields is science fiction, not science. Same with plasma guns from those tiny little asteroids that orbit Mars and will one day crash into it. Where are you going to get the materials to create a planet sized shield? Don't say we'll just mine asteroids, see below about cost. How long would it take to construct? If you create a shield to block the solar winds you'll also be blocking the light. How do you propose to heat the planet? Build tens of thousands of coal and gas fueled power stations? Constantly ship that fuel there? Send hundreds of millions of cars and drive them around? That's part of what's heating Earth right now. By less than 2 degrees Celsius in two hundred years. You need way more than 2 degrees warming on Mars. Humans in space lose about 1-2% of their bone density in hips and spine per month. Women giving birth on mars will shatter their pelvises and break their spines. We don't even know if a human fetus will develop in space. What affect does weightlessness, or Mars' much lower gravity, have on a developing fetus? We evolved to live on Earth, not another planet. In the end, even if all the thousands of problems were technically solvable who's going to pay for it? It would require capitol to be invested in those solutions. Capitol is only invested for profit. What's the profit motive of colonizing Mars? Don't say to 'save mankind.' That's not a profit motive, just look at what people do to make a profit at the expense of other's well being throughout history and today. Human nature is human nature and will not change. There will never be a Star Trek like utopia. Colonizing Mars isn't science, it's science fiction. And remember that fiction means make believe. It's a fantasy, not something that will become reality.

KEEP LOOKING UP

I believe that we need a core like earth's inside mars to produce a magnetic area around the planet to maintain an atmosphere and I don't believe just teraforming will do that. So as far as a new life like planet like earth is really worth considering unless you can produce a solar storm protection system around mars.

In soil, you also usual have other referees like fungus usually, you could say that soils usually change through a sort of "adiabatic" slow process of succession, something dies falls onto an already established microcosm and so on, what this is about is trying to create a completely new simplified soil that is already in such a pseudo equilibrium, which is difficult, we have been dealing with the problems of that sort for a really long time, in agriculture, and whennwe do that it introduces a broken equilibrium in the succession process of soils as part of the biosphere, this problem is sort of the same kind of problem as that but in a more elementary way than changing the plants to grow there andnraking up the soil layers. I think we need more commedians on it. 🍻

What most people don't consider. You would not only have to generate enough atmosphere to make the planet livable but extra to compensate for what is constantly being lost. It's not like an atmosphere can be created then it will remain stable from that point forward. And who is going to pay for the extreme expense of doing that? Just imagine the power needed to do so. What no one ever considers when speculating about this kind of stuff is the capitol investment that would be required to do any of it and capitol wants to see a return on the investment. If there's no profit, there's no investment.
