Guest essay by Eric Worrall
The humble potato is apparently so adaptable to different climatic conditions, NASA scientists are conducting serious tests, to see if the hardiest varieties could grow on the planet Mars. My question – what does this radical adaptability say about climatic food resilience, back here on Earth?
Echoing Ridley Scott’s The Martian, Nasa is running tests to see if potatoes could survive the climatic extremes of the red planet
…
“The Martian is completely possible,” says astrobiologist Julio Valdivia-Silva, the principal scientist working on the experiment in Peru.
Valdivia-Silva says the technology is growing at an “exponential” rate just as efforts to learn more about Mars are gathering pace.
Valdivia-Silva and his team aim to replicate Mars-like conditions on earth using a dome to create the same atmosphere, and soil consisting of sands brought from the Pampas de la Joya desert, part of the Atacama desert in southern Peru and one of the world’s driest and most nutrient-poor ecosystems.
Why the potato? The resilience of the humble spud combined with its huge number of species, genotypes and varieties means it can be grown from sea level to 4,700 metres above sea level while resisting drought, extreme heat and cold, salinity and UV radiation. It is also pound-for-pound one of the most nutritious staples as it is packed with vitamin C, zinc, iron, proteins and carbohydrates.
But Mars may be a whole new league of inhospitability. Temperatures on the planet vary wildly, between a high of 20C (68F) at its equator in summer to a low of -153C at the poles, according to Nasa . Its atmosphere is 95% carbon dioxide, 3% nitrogen and just 0.13% oxygen, which means the potatoes may grow fast but end up undersized. In addition, the dusty planet lacks ground water and there are winds of up to 60mph.
Water might be the biggest issue. Air pressure on Mars is so low, any liquid water usually just boils away. Even attempting to trap the water vapour in a plastic greenhouse, like the movie “The Martian”, might not help. All the potatoes I have ever grown love their water. But these conditions, low pressure, low water boiling point, extreme dryness, also apply to a lesser extent to the thin air of the High Andes, the source of some of the varieties of potatoes being tested.
One thing for sure – if a major, staple food crop is so adaptable, there is a realistic chance of growing it on another planet, claims that a few degrees global warming might cause mass starvation are utterly implausible. Absolute worst case, we might all have to develop a taste for more potatoes.

Actually it’s not. They all died when the hab failed.
Also The Martian was written by Andy Weir not Riddley Scott.
It sucked, no matter who wrote it !
Yes, the film was pathetic scientifically. But this question of terraforming Mars is highly relevant to all the money that is being thrown into climate modelling.. The carbon scare tactics are just an excuse for the tens of billions of investment. The danger is that thwy will similarly try to use carbon scare tactics to justify doing there initial testing on our home planet rather than Mars.
RS just directed it.
Marcus: Did you read the book or just watch the movie? The book was an excellent traipse through the difficulties he faced.
Well isn’t that special ! Did you ever see such a culturally diversified mess of potatoes in your life ??
You can buy that same exact trial mix at the Sunnyvale Farmers Market on Saturday mornings. All organic and bristling with carbon.
g
Egad. Did NASA never hear of Lichen?
Lichen is pretty much plant, animal and fungus in a single organism. A self contained ecosystem, where the waste of one component is food for the next. If Lichen can’t terraform Mars nothing can.
Don’t you need minerals there ferd, to make a quorum ??
g
But will they be baked or mashed ?
Boil ’em, mash ’em, put them in a stew!
Gollum gollum
Roast ’em with Lamb and green peas, along with some mint sauce. Good enough for Christmas dinner. Follow it up with Christmas pudding, containing thrupenny bits, to cut your teeth on.
The coinage needs to be cauterized in HF followed by DI water, before cooking them in the pudding.
Otherwise OSHA will get you.
g
Probably Freeze Dried
Baked in duck fat.
French fried.
Wouldn’t any Humans on Mars have to live in a pressurized environment any ways ??
Yes, but if food can grow in near Mars ambient conditions, it drastically simplifies the job of keeping the people in a permanent colony fed. There are plans to make the atmosphere of Mars more human friendly, most likely utterly unaffordable for today’s global economy – but a century or two from now, who knows?

..Thanks
Wait…you mean it’s OK to change the atmosphere on a planet we do not live on, were not born on, did not evolve on…to invade like a plague and alter it to make it more human friendly…but it’s a moral, philosophical, scientific, and GREEN failing to have any affect whatsoever on planet Earth?? :-O
Buncha hypocrits. 🙂
I think you have been watching too many Sci-Fi movies Eric!
The physical properties of H2O don’t change just because it’s Mars. At Mar’s Low pressure – all the liquid water boils away at any biologically relevant temp for which the potatoe’s enzymes and cell walls evolved.
Dead is dead when the liquid water boils away or forms ice cyrstals rupturing cell walls and cell organelles.

Dude! They will just use heavy H2O man. That’s real heavy….man!
The first Integrated Space Plan of 1989 saw terraforming of Mars to begin around 2040, using asteroids to be brought in from the Asteroid belt and crashed into the poles thus creating an atmosphere that would produce a greenhouse effect….

Not sure how they will “solve” the magnetic field, gravity and radiation “problems” on Mars for current humans in their current form, but it seems they believe smashing rocks together is what we do best to solve problems! Does CO2 (~95% CO2 atmosphere) filter out UV? I don’t think so, so in that case the planet will be sterile (Given an earth based example). If we earth bound apes ever get to deposit our “DNA” on another rock, I am sure, given time, that life will evolve into a new species, humanoid, but not human as we know it. And this rock as well as Mars has a “shelf-life” of ~5billion years before being consumed by Old Sol!
I guess we had better get to it. Oh wait…we are still throwing rocks at each other, in disagreement as to which God is “THE GOD” and worrying about that deadly planet killing trace gas CO2.
Meanwhile, all OTHER life on this rock will continue, until it can’t, and it won’t be THEIR fault!
They cant get CO2 satellites into orbit mate. Strangely they are also with Orion doing work to make it safe for Astronauts to travel through the VA belts, but I thought we did that without any problems with 1960s tech.
I also fail to see how we can change the atmosphere for Mars when we can’t even figure out CO2 in our own.
NASA is one massive black hole (the only one ever found) for swallowing money
Patrick MJD March 16, 2016 at 11:37 pm
Haha…it was 1989, they were under pressure from Pres. Bush Snr to come up with a plan for the century ahead….and it was not intended for it to be in the public domain for people like you to questions…plus as they say…it seemed like a good idea at the time.. If you look at the website from which it came…the plan is being updated and problems wrt terraforming raised…
https://integratedspaceanalytics.com/cms/content/integrated-space-plan-2015-edition
Btw…there is a certain irony that if it weren’t for the primitive V2 era ‘rocks’ being thrown around at each other on Earth…this discussion about growing potatoes on Mars would not be taking place.. )
It is becoming economically viable to grow certain food-stuffs in vertical farms near cities. If growing plants indoors, under artificial light, makes sense on Earth, then surely doing so on Mars would too.
https://en.wikipedia.org/wiki/Martian_lava_tube
Aphan: Are you referencing the rise of genus homo?
Even you can’t grow them in a martian atmosphere, if the pressure and temperatures don’t have to be as high as required by humans, construction requirements and hence cost still go way down.
Patrick, a thicker atmosphere means liquid water becomes possible, with that you can get plants growing which in turn will create O2. Once O2 levels start building up, so will ozone levels, which will take care of the UV problem.
There is still the problem that the lack of a magnetic field means the solar wind will immediately start stripping away your atmosphere, but that will take millions of years.
One thing to pressurize a small house, some work facilities and their suits. Another thing altogether to pressurize acres of farmland required to feed people. Probably many acres based on how little sunlight they will be getting there compared to the closer Earth.
..Maybe they should try mushrooms…NASA is full of SHlT anyways…LOL
We can just suck all the CO2 out of the atmosphere there like they tell us is feasible here and cool that planet down to perfect. Humans are Gods…:)

To turn it in to a largely frozen rock? Oh wait…
If it’s a dead rock, why not? A dead rock in a gravity well is almost useless to us.
But a living rock in a gravity well is exactly what all the exo planet hubbub is about.
If we can get that from mars in a few hundred years, frankly, it’s a no-brainer.
I’d love to see it commence in our life times.
Saves on all that tedious living in a plastic Martian Yurt complex, too.
I’m actually very excited to see what they do for Orion for some clues about what may have happened in 69. I believe we landed on the moon but dont necessarily believe the official narrative. There are a host of implausible explanations I’m sticking with my opinion that the money shot images were done on earth studios. Armstrong missed his calling as the next ansel adams without an eyepiece and camera strapped to chest. Beautiful shot after beautiful shot in sequence no accidental images of the ground or bad framing or missed f stop. N ever A S traight. A nswer
What specifically are you doubting? If we actually went to the moon, then anything we could do on the moon would be easier actually done there rather than faking it. Sorry, but this is one of the conspiracy theories that makes LESS sense when you try to meet it halfway.
As for the perfect shots, that’s because you saw about 2-5% of the photos, and most of those were cropped to center the image (perhaps they were otherwise retouched for magazines, but I have no information on that). Also, NASA has every last original negative in a vault in Houston, but most aren’t worth looking at because of the points you said. According to NASA, they brought 2 magazines (of 160 shots each) plus 33 rolls of film. They don’t say the number of shots in Apollo 11, but Apollo 8 brought back 1,100 photographs despite having less film. With that many tries, you’re bound to have a good number of perfect photos.

I came within a closed requirement of getting to work on the test code for the Orion project. That is I was told I had the job, but before the background check could be completed the req was closed.
Dang, that was one job I really wanted.
I really, REALLY hope my tax dollars aren’t paying for this.
I thought NASA’s current main goal was Muslim outreach 🙂
..That was the day I lost all respect for NASA !
“That was the day I lost all respect for NASA”
I’m betting that it wasn’t a task they requested.
“That was the day I lost all respect for NASA”
================
forit was the day NASA announced the early end of the moon program and there next great mission: “Mission to Planet Earth”.
Seriously you can’t make this stuff up. NASA’s great idea after the moon was to travel all the way to planet earth. And folks wonder if the moon mission was faked. Surely anyone with the technology to travel through billions of miles of space and arrive at earth could manage a trip to the moon.
No magnetic field.
I suppose Oxygen would be a wee problem too !
More than compensated for by the beautiful fertile, moist mud which is predominant on Mars.
I doubt you could grow potatoes on Mars without doing it in a greenhouse with some kind of climate control.
mars is 95% greenhouse gas. so according to NASA GISS that should make Mars super warm. I’d be surprised if Gavin wasn’t joining the potatoes on the first mission.
But…but…it only works here on planet Gaia.
Since water is so hard to come by on Mars, would it not make more sense to use some sort of closed loop hydroponics as a means of growing stuff? (Maybe even include a Tilapia fishfarm in the loop too to aid the nitrate / nitrite cycle)
Would enough of the water evaporate from the soil & plants be collected on the dome?
Would it not follow gravity and just sink down into the groundwater ?
Wait there’s groundwater on Mars ?!
Surely some of the water that shaped the canyons eons ago sank into the ground !
Send up the drilling rigs…
All you need is a Mormon, a few potato eyes, and you will have potatoes. In fact, if they ever colonize Mars, the first ones there will be Mormon agricultural companies. They are good at it.
Pamela! I have seeds, A purple potato that breeds true, grows in really tough conditions, long or short season. And is very tasty. But takes about 3 generations of tuber propagation to be able to produce 6 to 8 oz tubers @ur momisugly projected yield of 500 sacks to the acre. A good yield for any variety. After 3 years in the refrigerator the seed germination was over 70%. So I now have several hundred new plants to again test…pg
Maybe a better idea would be to use CRISPR–Cas9 and genetically modify humans to have reptilian traits. Take the best parts of snakes, lizards and turtles and cook up some really low metabolism features and edit our DNA. It maybe possible to drastically cut down our calorie/water/oxygen requirements. Throw in some gene-drive technology and we won’t even have to start from scratch with embryos we can just modify existing adult specimens. It’s a brave new world eh?
I think that’s how we were made. Tinkering with different DNA and monkeys. There is no fossil record to support that. No half or part human and ape fossils. Neanderthal is not the link. It’s human.
Yeah, but what about Piltdown Man!
Oh… wait… that was a different scientific f*r*a*u*d. Never mind.

Pilt down man was fake. Look it up

But not Piltdown Mann
I hear that Piltdown Mann was really good with a hockey stick.

It is totally beyond me how you could have possibly missed the sarcasm in my remark (dripping with sarcasm and even included a /sarc tag) about Piltdown Man.
Might be that’s why I labeled it f*r*a*u*d and provided a link?
I know it was a fake. How did it go to me not realizing it???? I KNOW I didn’t come from monkeys how about you?
1wanderingtruthseeker
No kidding…
Really. You’re going to have to help me. Please re-read my response to you. How is it humanly possible that you missed the dripping sarcasm, the link to a detailed description of the fakery and the /sarc tag thingy and the end of my comment?
Modify our calorie/water/oxygen requirements yes…but then….what critters do you come up with for us to eat that will thrive on Mars?
Mars bars.
Then why not just stay here? Genetically modify humans to withstand deadly 500ppm of CO2 and a horrific 1.1C of warming? Potatoes grow pretty good here.
Yes!!! The Matian guy grew them. Plants give off oxygen. If they had big better habs, They could grow trees!
Why not? My wife’s potato salad tastes out of this world.
But then you have the Martian Mayo issue.
Even if there were sufficient carbon dioxode, water, oxygen, and daytime highs near 70 degrees Fahrenheit, the extreme cold occurring every night, well below freezing, simply precludes the growing of nearly all plants without special protection, such as a greenhouse.
The extreme cold of Mars prompted me to pose the hypothetical question: If CO2 is a greenhouse gas that traps heat, then how much CO2 do we need to add to Mars’ atmosphere to produce a warmer climate?
That’s when I learned that Mars’ atmosphere is already 95% CO2. And, there is no formula for how much heat CO2 traps. We can’t even formulate an equation for the “greenhouse gas” property of CO2 when it makes up 95% of the atmosphere. We should be able to measure how much heat and for how long the Mars’ atmosphere traps when the sun goes down. Alas, there is no such formula and there is no way to measure the greenhouse gas property. Is it the only property that can’t be measured? If NASA did have a way for the Mars’ Rover to measure the heat trapping effects of the atmosphere, it would necessarily be on the same order of magnitude as how long a room full of mirrors stays lit after turning off the lights.
Three sister planets with relatively similar sizes and distances from the sun:
Venus 95% CO2
Earth .004% CO2
Mars 95% CO2
One of these planets supports Carbon-based life forms which consume CO2 when considered in totality.
Mars actually has more CO2 in it’s atmosphere than the earth does. Not percentage, but total.
That’s assuming a lot about access to different crops, knowledge of their cultivation and climatic limitations, understanding of the different hardnesses to different environmental stresses, and acceptance of the change in food.
This is the reason why a lot of adaptation to climate change goals align with development goals in the world’s poorest places. The key element is going to be education.
The rainfall in Africa is very sensitive to SST, and it is often considered that the droughts over the past 30 years may have been contributed to by AGW. “May well have happened already” is probably more accurate than “utterly implausible”.

Complete garbage Seth. If you support this post and it’s contents, you have no clue about weather in Africa.
Hi Patrick.
I’m trying to understand what you think is complete garbage.
Do you claim that both African rainfall is not very sensitive to SST, and that recent droughts have not been attributed in any part to AGW?
And is your very best evidence for your position “you have no clue about weather in Africa”?
Everything bad has been attributed to CO2, so the fact that a few nut cases are claiming that droughts in Africa were also caused by it is not evidence of anything.
Averages don’t matter to plants. It’s the extremes that make or break a successful garden. What does it matter if daytime temps on Mars are OK for potatoes if nighttime temps are not: “A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).” Note – minus 70 C at night even in summer!
Also, the air pressure is so low that there is no surface water (outside of polar ice).You would still need a greenhouse like structure to create sufficient atmospheric pressure to allow the soil to retain moisture.
(Low density of atmosphere makes movie plot thickener of winds (up to 60 mph) able to plow spaceship over impossible.)
SR
…blow spaceship over… of course
SR
> Low density of atmosphere makes movie plot thickener of winds
Just like on Earth, CO2 is capable of doing whatever is required of it to drive the plot forward.
I hear you, but there are some interesting features of the experiment;
1. Potatoes grown in the Andes must be very frost tolerant. I’m not sure if that means -70c frost tolerant, but a large part of the growing season nighttime would be very cold. Worst case it might be possible to drape plastic over the fields, the way plastic is used on Earth to protect fragile crops at the cold start of the growing season in Northern latitudes. Or it might be possible to warm the crop land a little, say with a microwave beam from a solar power satellite.
2. Air pressure is low, but partial pressure of CO2 is higher than Earth.
I agree about the water thing, but there might be possible solutions. Apart from the Matt Damon greenhouse idea (so maybe just enough above ambient pressure to make liquid water feasible), there are locations on Mars where the air pressure is unusually high, the bottom of really huge impact craters, that sort of thing, places where the surface is thousands of metres below Martian ground level.
e.g.
https://en.wikipedia.org/wiki/Hellas_Planitia
It would seem Eric, that a handy precursor would be to seed mars with Earth’s more hardy Antarctic bacteria and plants (not a lot of those outside the presence of liquid water) and let that run exponentially for a century, to help mobilize nutrients and build some essential carbon content as the basis for slow soil formation. You need dead bacteria in there to get the carbon build up.
Now if you could get a surface bacteria or plant bloom, such as a dark green lichen, for instance, that would made albedo much lower, so absorb much more of the radiation at surface, so you’ve just made life so much easier and introduced viable global photosynthesis.
High albedo and low light is after all Antarctica’s problem, for supporting life and thus limiting heating need for maintaining liquid fresh water.
If there are viable niches for extremophiles they’ll find it, but only if you distribute them on the air with drones, distributed at high altitude from a falling capsule and putting spores into the atmosphere, at a range of latitudes and altitudes.
So keep seeding the drone capsules for 100 years, year after year, and its bound to seed the planet and begin blooms in isolated locations. Then it’s a wait and see.
Lichen
Response to environmental stress
Unlike simple dehydration in plants and animals, lichens may experience a complete loss of body water in dry periods. Lichens are capable of surviving extremely low levels of water content (poikilohydric). They quickly absorb water when it becomes available again, becoming soft and fleshy. Re-configuration of membranes following a period of dehydration requires several minutes or more.
In tests, lichen survived and showed remarkable results on the adaptation capacity of photosynthetic activity within the simulation time of 34 days under Martian conditions in the Mars Simulation Laboratory (MSL) maintained by the German Aerospace Center (DLR).
The European Space Agency has discovered that lichens can survive unprotected in space. In an experiment led by Leopoldo Sancho from the Complutense University of Madrid, two species of lichen—Rhizocarpon geographicum and Xanthoria elegans—were sealed in a capsule and launched on a Russian Soyuz rocket 31 May 2005. Once in orbit, the capsules were opened and the lichens were directly exposed to the vacuum of space with its widely fluctuating temperatures and cosmic radiation. After 15 days, the lichens were brought back to earth and were found to be in full health with no discernible damage from their time in orbit.
https://en.wikipedia.org/wiki/Lichen
And remember those those windy Marian dust storms?
—
Reproduction and dispersal
Vegetative reproduction
Many lichens reproduce asexually, either by a piece breaking off and growing on its own (vegetative reproduction) or through the dispersal of diaspores containing a few algal cells surrounded by fungal cells. Because of the relative lack of differentiation in the thallus, the line between diaspore formation and vegetative reproduction is often blurred. Fruticose lichens can easily fragment, and new lichens can grow from the fragment (vegetative reproduction). Many lichens break up into fragments when they dry, dispersing themselves by wind action, to resume growth when moisture returns.

They need very clean air. New Zealand is a great place to study them, even hang from trees. I studied them in a place called Pitlochry in Scotland, a beautiful place by any measure, albeit a bit wet a lot of the time LMAO.
Pitlochry is beautiful, played on the golf course there once, a long time ago.
Averages don’t matter to plants.
That’s not exactly true, although it may not matter for cultivars as much.
Here’s a for-instance looking at Australian Eucalypts – While temperature extremes cover dozens of degrees, the majority of species are outcompeted outside a narrow range of mean annual temperature, of a few degrees. Fully a quarter of species are naturally constrained within a range of less than one degree celsius.
We present data on the climatic ranges of 819 species of Eucalyptus L’Herit in Australia, in terms of mean annual temperature and rainfall. 53% of species currently have ranges spanning less than 3°C of mean annual temperature, with 41% having a range of less than 2°C, and 25% with less than 1°C 23% of species have ranges of mean annual rainfall that span less than 20% variation. – Climatic Range Sizes of Eucalyptus Species in Relation to Future Climate Change

Plants know and understand averages, a human, made up, construct? Really?
I kinda favour steering a few wet comets into Mars. Without any life forms beyond soil bacteria and maybe mushrooms that live on them, what’s the issue? Mars used to be wet and watery. We can just fix that up. The atmosphere has to be initiated at a scale large enough to support a plant system that can maintain it for a few hundred centuries. By planning the impacts carefully, the mass and orbit can be tweaked to match well. Once there is enough atmosphere to support liquid water, the biomes can be established.
There may be a heck of a lot of water underground. The Earth’s mantle contains about twice as much water as the surface oceans.
The Horizon spacecraft fly past Pluto last summer and discovered the dwarf planet’s surface is covered with water, mostly ice, H20. Water has been observed to flow on Mars. We are essentially certain oceans were once present on Mars. Water seems to be present in massive quantities on some of Jupiter and Saturn’s moons. Even the dwarf planet Ceres in the asteroid belt is thought to have liquid water beneath it surface.
What is the source of all this extra terrestrial water? Maybe there are more wet comets out there delivering water than we suspect. http://smallcomets.physics.uiowa.edu/
Averages don’t matter to plants.
=============
don’t let Mikey Mann hear you. a whole branch of science believes you can calculate the average temperature of the earth based on what trees have to say, so long as you make sure to chose the right tree. Not all trees have the story right. The skill is in recognizing those trees that grew up telling lies, and those trees that grew up telling the truth. That skill requires a true scientist.
A better solution than actually going to Mars would be to have people surreptitiously live in a televised Martian movie set here on Earth – you know, like Big Brother.
They need to plant a bin of the potato’s garden cousin, tomatoes. And basil. Otherwise, I’m not going.
With all that fossil fuel burning, global warming and stuff, shouldn’t they rather be testing conditions like on Venus? ’cause that’s where we’re headed. /sarc
The Irish largely colonized Aust so we know who to send to Mars.
Nope! The Abo’s beat them, me, you, us to it!
“That’s not a colonization … this, … is a colonization!”
Just a potato joke. 😉
I guess you have not been to France/Belgium with a toothache. The pain killer will fit, not sure about the potato tho!
The Irish never had ships at that time to journey that far…
They went there in leg irons chains Patrick. Got a sense of humor?
I don’t know why they’re going through all the trouble to do some actual testing of potatoes growing under harsh conditions – why don’t they just model it?
Here’s the answer:

Phil, thanks for the illustration of the model results. Seems to match reality quite closely.
That’s about what a potatoe Gen3 would look like after about 300 sols of Martian surface cosmic ray bombardment DNA damage… If it grew at all.
Ah but that model was derived from….yee gads, OIL!!!!
They need Monsanto to gene modify to withstand those nasty conditions and then slip in some weed mod’s to accompany so they could sell Roundup. Hey, Just started another conspiracy theory!
It makes more sense for NASA to research growing potatoes on Mars than speculating about temperature rise on earth.
Why force plants to grow in marginal conditions for marginal yields? Why not pamper them and harvest abundance?
http://www.gefoundation.com/the-future-of-agriculture-indoor-farms-powered-by-leds/
BTW, is there a way to simulate Mars gravity in NASA’s experiments?
They’re not simulating gravity. RE pampering, you are of course right – its a tradeoff between low yields and the cost of pampering, with a likely sweet spot somewhere between the two extremes. Of course, if by some miracle you could get a potato to grow outdoors, in unimproved Martian conditions, the vast land area available might make up for low yields.
So, let me get this. NASA thinks a plant that evolved in conditions on this rock, will be OK to plant on another completely different, un-earth like, rock? And here’s me thinking NASA lost it with the Muslim Outreach program. NASA seems not to be too worried these days about earth organisms contamination a alien world.
Agree. NASA is screwed up thinking long term manned space flight beyond LEO has any realm of reality. Potatoes…. Shheeeesh!!! The research grants given out to study these things.
I’d rather they work on GM potatoes to grow here on old Terra where people can actually live.
You might like this…”What about the veg….”
Comments? Comments? Please people. We don’t need no stinkin’ comments. Some stories just speak for themselves. As for me, I’m speechless.
The one thing that amazes me about folks who want to go live on Mars…. WTFO!!!
It’s colder than Antartica, lethal in atmospheric pressure, and sterilizing for life due to solar UV and cosmic ray bombardment. Again … WTFO???
One word…. Robots.
While I sit by my pool on a comfortable summer night enjoying an adult beverage, some AI-enabled robot can tell how fucked up it is on Mars via my iPad.
