Would you trust Musk with hundreds of H-bombs?
Elon Musk Wants to ‘Nuke Mars’ for Humans to Live—But There Is One Problem
By Sissi Cao • 08/16/19 12:17pm
Firing nuclear weapons at Mars might have been the last idea on Elon Musk’s mind before going to bed last night. “Nuke Mars!” the Tesla and SpaceX CEO tweeted Thursday night a few minutes past midnight, prompting a Twitter frenzy with over 100,000 likes by Friday morning.
…
He later clarified that the plan is not to drop nuclear bombs on the surface of Mars, but in the sky above its two poles. Specifically, Musk wants to drop hydrogen bombs (which use fusion) into the atmosphere above the Martian poles every few seconds to release the carbon dioxide trapped inside Mars’ ice caps.
Because CO2 is a potent greenhouse gas, the more CO2 Mars can release into the atmosphere, the warmer the planet’s surface will be. The effect is similar to how the fusion process inside the sun produces energy to keep Earth warm.

The article goes on to cite a study which concludes that the plan is not feasible.
Inventory of CO2 available for terraforming Mars
Bruce M. Jakosky &
Christopher S. Edwards
Nature Astronomyvolume 2, pages 634–639 (2018)We revisit the idea of ‘terraforming’ Mars — changing its environment to be more Earth-like in a way that would allow terrestrial life (possibly including humans) to survive without the need for life-support systems — in the context of what we know about Mars today. We want to answer the question of whether it is possible to mobilize gases present on Mars today in non-atmospheric reservoirs by emplacing them into the atmosphere, and increase the pressure and temperature so that plants or humans could survive at the surface. We ask whether this can be achieved considering realistic estimates of available volatiles, without the use of new technology that is well beyond today’s capability. Recent observations have been made of the loss of Mars’s atmosphere to space by the Mars Atmosphere and Volatile Evolution Mission probe and the Mars Express spacecraft, along with analyses of the abundance of carbon-bearing minerals and the occurrence of CO2 in polar ice from the Mars Reconnaissance Orbiter and the Mars Odyssey spacecraft. These results suggest that there is not enough CO2 remaining on Mars to provide significant greenhouse warming were the gas to be emplaced into the atmosphere; in addition, most of the CO2 gas in these reservoirs is not accessible and thus cannot be readily mobilized. As a result, we conclude that terraforming Mars is not possible using present-day technology.

Its probably worth having a closer look at Mars before dismissing the idea. The opportunity is potentially so enormous we shouldn’t write off the plan based on an aerial survey; a ground based survey might settle the question more definitively.
But even if this daring plan gets the go-ahead, I’m not keen on Musk being the person in charge of all those H-bombs.
Elon Musk should not be in control of anything explosive, let alone an H-Bomb.
That’s why his cars have autopilot.
Too late, he has already created the ever explosive Tesla Battery Pack
Recently a Tesla S burst in to flames in Hong Kong, Tesla then deployed a software update to those vehicles that had their WiFi internet connections on and “downgraded” the performance of the battery. Tesla said it was an “upgrade” to preserve the life of the battery. Someone in America wasn’t too happy about that and is bringing a class suit action against Tesla over it.
Tesla: Saving the planet by consuming more resources in more cars!!
Forget using nukes to make Mars warmer. He’s going to have to change the composition of atmosphere to 78% N2, 21% O2 and the remaining trace gases including about 0.04% CO2 and with a pressure of about 14psi, so a very thick atmosphere on Mars. How is Musk going to get rid of 97% of the current Martian atmosphere, CO2, ‘coz nukes won’t do it?
Mars needs both more gravity aka mass and a magnetic field. Even when (if) Mars had water, per the information we currently have, the internal structure the planet is different so it will never again (if ever) have an Earth like atmosphere. It has little to no internal heat and is barely able to keep any solar heat with a what a 97% CO2 atmosphere already.
Any gas we managed to release will just be removed by the solar wind. Due to the aforementioned no magnetic field and not enough gravity to compress any of the gases out of the atmosphere into a liquid.
Hell where is the ethics and morality in this equation!?! There may be some life on the planet, not complex life. Should we not, at the very least, confirm that it is a biologically dead world first.
He wants our first act in colonizing a planet to start with a possible sterilization plan; to become a Destroyer of Worlds species. And people look up to this guy?!? –> almost makes me want to create a twitter accout
Honestly, a part me wishes we could do, to show once and for all that CO2 is not a zero-point module; perpetual motion molecule.
Some of the released CO2 may be carried away by the solar wind but most will just freeze again at the poles, restoring Mars to its stable condition. And that will happen pretty quickly, probably within a Martian year.
It would be far better to direct one or two hundred comets at the surface. What is missing is water – lots of it, to thicken the atmosphere, then bacteria to convert the available gases to something approaching that of a diving bell or earthship.
There is so little CO2 it will quickly drop as a % of the total.
The impacts would be far greater than a hundred h-bombs. It the comet’s (or asteroids) were well targeted, the orbit could be brought in towards the sun while speeding it up slightly to compensate.
We done have to do it in our generation, it is a long term project. The potential benefit is large, not to mention fun.
I’ll add that it is extremely likely there are life forms on all the planets, with Martian ones most similar to what we understand about microbiology.
Amen.
One word, magnetosphere. Even NASA knows there is none to protect any atmosphere on Mars.
“Therefore, it is Mars that is the real mystery: it is pretty cold and is quite like Earth in many ways . . . so why no magnetosphere?”
https://mgs-mager.gsfc.nasa.gov/Kids/magfield.html
In a few words…Cold Core
Hot > magnetivity
Ditto. … and the lack of a planetary magnetic field also results in no protection from cosmic radiation which makes human habitation almost impossibly difficult, if there was a reason ….
I have not heard of any commercial or human reason, for humans to travel to the planets. The old science fiction stories have become fantasy.
The old science fiction stories did not know about cosmic radiation and assumed the asteroid belt include material from the core of a Mars size object that Jupiter destroyed.
The purpose of space travel in the old science fiction stories was to get heavy metals from the asteroid belt. Science fiction stories assumed technology such as fusion drives which are no where in sight, to bad.
It has now been shown that there never was a Mars size object. The asteroid belt does not contain concentrated core material and heavy metals.
This finding disproved the so called late heavy bombardment theory which was created to try to explain why there is concentrated heavy metals on the earth.
Where has it been shown the asteroid belt does not contain disrupted core material? I grant you that of the few asteroids orbited the max gross density of 3.4 g/cc places limits on things, but icy crusts around dense cores is still a possibility. If dense cores are not possible, where do Iron-Nicole meteorites come from?
I believe they form based on temperature. There is also interesting evidence of flash burning of some of the material.
William Astley
“Based on temperature?” What does that mean? Also, what do you mean by “flash burning?”
The flash burning are meteoroids that have been exposed to high temperature. The assumption is the burning is due to some electrical discharge.
Temperature is the surface temperature of the object based on its distance from the sun with rocky planets forming close to the sun and gaseous planet in the outer orbits.

“NASA recently approved a mission to visit the metallic space rock, which orbits the sun in the main asteroid belt between Mars and Jupiter. The mission — the first to a metal asteroid — could reveal secrets about our solar system’s earliest days while setting the stage for a future space mining industry.
“We think the metallic class of asteroids are the remains of ancient cores of planets,” said Jim Bell, a planetary scientist at Arizona State University in Tempe and deputy principal investigator of NASA’s Psyche mission.”

“I have not heard of any commercial or human reason, for humans to travel to the planets.”
How about for exploration? We don’t need to live on planets and moons with hostile environments. Instead, we can build artificial habitats that orbit our objects of exploration, where we can make the environment suitable for human health and safety by providing artificial gravity and radiation protection.
Humans *will* be moving into space. That debate is over.
“which are no where in sight”
google “Project Orion”
The LHB hypothesis was to explain moon rock dating, not heavy metals on earth.
NASA has a plan to give Mars an artificial magnetosphere:
https://www.extremetech.com/extreme/245369-nasa-proposes-building-artificial-magnetic-field-restore-mars-atmosphere
Why? Something whacked Mars good and hard, millions of years ago, when it still had surface water, and blew out the entire core through a massive crack (now a chasm) and three major volcanoes, and the magnetic core of Mars now sits on the surface as red dust. There is still surface water in the form of water ice on Mars, but if there is any below the surface, then only Gekko the Senior Martian and Willis the Bouncer know where it is and how to find it. (See “Red Planet” [Heinlein] for reference.)
Really, will someone please let me know when Elon Musk stops consulting with the Good Idea Fairy??? Thanks!!
“blew out the entire core through a massive crack (now a chasm) and three major volcanoes”
Someone who believes that is hardly the right person to ridicule Elon Musk’s ideas, wild though they may be.
Gee whiz, it’s a shame you can’t detect sarcasm and satire without those labels attached. You’re not real bright, are you, sport?!?
You’d think a reference to Heinlein’s Martians (who live deep underground) would be a clue.
Sorry that I missed the sarcasm, but after reading a number of apparently serious pressure-equals-heat claims one tends to think that any nuttery here is serious.
So you’re already used to it:

Jupiter radiates more heat than it gets frome the sun because of internal pressure:

Bingo!!
No large moon?
The gent is barking mad and believes in nonsense. “Because CO2 is a potent greenhouse gas”
He gives mad scientists a bad name.
Karabar
“Because CO2 is a potent greenhouse gas, …”
What if that belief turns out to be wrong?
Exactly, since CO2 is the world’s best coolant. Thermodynamic physicists cannot get CO2 to warm anything, but it’s a great coolant. Mercedes is now using CO2 in the auto A/C units and new skating rinks are using only CO2. The dirty little secret is that rising CO2 tends to cool the planet, radiating at night. However, as rising CO2 displaces absolute water vapor and water vapor is a more powerful radiative gas, rising CO2 very slightly does warm the climate, but only a a gnat’s wing thickness.
Charles Higley – August 17, 2019 at 7:58 pm
OH MY, …… so that is why Charles Keeling moved his laboratory to the top of Mauna Loa, ….. RIGHT?
This really is very simple. There is no need to debate a theory, as we have the evidence used to test modeller’s predictions. The models that are based on the assumption that CO2 is “potent” utterly fail to predict the much smaller observed change in the greenhouse where it will be a maximum if real. As measured by satellite and balloon since 1979 and reprted by University of Hunstville Alabama to the US Government by the scientists who created the award winning programme for NASA. . Of course this is hardly surprising as the modellers use arbitrary amplifications for CO2 that they simply make up to suit their rhetoric and grant funding objective, to prove CO2 a problem. In fact the contribution from CO2 is known to be tiny and its effect to decrease logarithmically with concentration through the band saturation effect, so in reality it is a LOT less potent than the dominant natural greenhouse effect of water vapour. The models are wrong.

At breakfast yesterday, we watched a CO2 truck charging the carbonating system of a restaurant across the street. As the fog of venting CO2 vaporized we could feel the heat wave engulfing the planet! /s
While we’re coming up with weird and wonderful ways to warm up Mars, I’m surprised Elon didn’t promote the solar panel route. One means suggested to ‘protect Earth from global warming’ was to place in Earth orbit a fleet of mirrors to reflect away the Sun’s light. Surely, this technique could be reversed for Mars in order to increase the amount of sunshine that hits the planet’s surface. Sending a load of high water content objects to crash into the planet would help to trap the extra energy.
Martian Bipolar Disorder created using nukes – a solution only Elon could imagine.
Let’s reanalyze this, shall we?
Barking mad to continuously pump up his reputation among the scientifically-uneducated and hysterically tout the evils of carbon dioxide at the same time? Relevant to the point may be the fact that belief in that mythology is necessary to drive government subsidies that are the entire source of his wealth.
Musk should have gone into the cologne business.He’s right up there in the ‘who’s who’ weirdo category along with Gore the bore.
The partial pressure of CO2 on Earth is 400/1000000 * 101325 Pa = 40.53 Pa The partial pressure of CO2 on Mars is 95/100*610 Pa = 580 Pa. The GHE on Mars should be significantly higher than on Earth even allowing for the reduced TSI. Would increasing the amount of CO2 actually make a difference?
By my calculations, there is around 3 times more total CO2 in Mars’ atmosphere compared with earth, but the apparent greenhouse effect is only .5 degrees. On Venus, it too has an atmosphere that is almost 100% CO2 but has an atmospheric pressure at ground level of 92-93 times that of earth. Its greenhouse effect is of course huge. High school science- PV=nRT . Pressure creates the heat. CO2 probably has almost no effect whatsoever (if any) , but we are being fed the propaganda under threat of retribution. The “proof” is that speaking out against the “settled science” gets you blacklisted.
3x more C02 on Mars?
I thought the atmosphere was 1% of the density on Earth’s atmosphere. That would mean there is the equivalent of a 10,000 ppm CO2 on Earth (ie if ours was 1% CO2). That is about 25x as much CO2, if you compare an equivalent volume of atmosphere, rather than the whole.
Obviously, that is why it’s so tremendously hot on Mars…
Actually, sorry, it’s only 95% CO2 on Mars, so slightly less.
No, you have that backwards. Temperature is the independent variable. P=nRT/V. Temperature creates the pressure. The sun creates the temperature.
What would the atmosphere on Venus be if by some unexplained process, it was thrown out of orbit into intergalactic space?
The atmosphere would all freeze solid as the temperature drops to about 3K. Pressure and volume would go to essentially zero.
I’m not sure what greenhouse effect CO2 is having on Venus, but any comparison between Venus and Earth is absurd since the maximum CO2 concentration we could conceivably drive by burning fossil fuels would probably not even reach 1500ppm (0.15%)
In any case there is lots of other greenhouse gases on Venus, CO, SO2. N2O, HF, HCl, H2O (yes, there is some) and other stuff we don’t even know of, probably even some metal carbonyles.
The type and percentage of GHGs in Venuses atmosphere is not the cause of its extreme temperature.
The density of Venuses atmosphere and its axial rotation speed are the culprits, to wit:
Isn’t that contraband science, even on this website?
Pressure does not create heat. Pressure increase creates heat.
This idea of pressure creating heat has me weirded out. The bottom of the Marianas trench should be boiling hot and temperature in the ocean should go up with increasing depth. Okay, perhaps it only works with a compressible gas. But, but , but?
If you have ever had a propane grill for a summer barbecue, you’ve probably noticed that the tank (which stores the propane at about 10 times atmospheric pressure), tends to be red hot. And we all know that the elderly patients who use oxygen are constantly suffering burns from accidentally touching the tank.
Wait, is that right?
Maybe our Zeller-Nikolov experts can ‘splain this to us.
Not only does PV=nRT not explain temperature, it is probably not even an appropriate equation of state to apply in any case. The surface pressure is so high that you likely have to use a real gas law–I.e. use a compressibility factor, Z.
I thought you members of the “misapplication of the ideal gas law club” were banned at this site.
Perhaps we should first figure out why Mars has no CO2 in the first place – if it was never there then why? If it was there at one time why isn’t it there now? Did it escape? Swept away by solar winds? Would it stay if we put it there now – and for how long would it be around – and how much warmer would it be if it DID stay around?
Lots of questions, no answers, not even a MODEL by Mr Musk.
It has CO2 in the atmosphere. A lot more than Earth as a matter of fact. And even more in the polar caps, which probably evaporates periodically naturally due to Milankovich effects.
But unfortunately CO2 is a weak GHG, with narrow absorption bands. What Mars doesn’t have is the important GHG, water.
I had always assumed that the first step in terraforming Mars would be to drop large ice asteroids onto its surface.. .
The pressure measured at Mars’ surface is equal to the weight of the column of atmosphere per unit area from the surface to infinity. Since Mars’ surface gravity is 0.38 that of the Earth, however, the total mass of the Martian atmosphere in that column would be 1/0.38 = 2.63 times that of the mass in a 1 g field. So the corrected corresponding partial pressure compared to Earth is 2.63 x 580 Pa = 1,525 Pa, the mass of CO2 in Mars’ atmosphere per unit area is about 37.6 times that of the Earth’s atmosphere. Mar’s radius is 0.53 times that of the Earth, so its total surface area is 0.53^2 = 0.28 times that of the Earth. That brings the total atmospheric CO2 content on Mars to 0.28 x 37.6 = 10.5 that of the Earth’s.
That’s more than enough to work with. What Mars could actually use more of is gases that absorb in the UV and above, such as oxygen and nitrogen.
“Since Mars’ surface gravity is 0.38 that of the Earth, however, the total mass of the Martian atmosphere in that column would be 1/0.38 = 2.63 times that of the mass in a 1 g field.”
So:
less gravity –> more atmospheric mass
no gravity –> infinite atmospheric mass
Got it.
Pressure is force/unit area, where the force is a weight of material. Force = mass*acceleration, or in the case of this example Weight = mass*(acceleration of gravity).
1 Newton of weight could correspond to 1 kg(mass)*9.80665 m/sec^2 (the gravitational acceleration at the surface of the Earth. A Newton is 9.80665 kg-m/sec^2. Thus 9.80665 kg-m/sec^2 of weight on Mars, where the surface gravitation is 3.711 m/sec^2, would require a mass of 2.643 kg.
To put it in more basic terms, mass is an inherent property of matter. Weight is not; it’s derived, and depends on the local gravitational field.
Using the surface gravity of each planet to compare surface pressures is of course an approximation. It assumes a uniform gravity field to the top of the atmosphere, among other things. So it’s a linearization, but not a bad one in this case.
If a small asteroid had a surface pressure (and temperature) equal to Earth’s, it would approach your zero g infinite mass case, but the problem is so non-linear by that point the linear comparison would be meaningless.
“What Mars could actually use more of is gases that absorb in the UV and above, such as oxygen and nitrogen.”
Asteriods and comets have oxygen and hydrogen in them. Musk should probably change tactics and build himself a nuclear orbital transfer vehicle that can go fetch suitable asteriods and comets and bring them to Mars and crash them into Mars’ atmosphere. Build up the atmosphere nice and thick and up come the temperatures, and it takes thousands of years for the atmosphere to dissipate so that leaves plenty of time to keep it topped up. 🙂
Colonizing Mars is much more difficult than simply building suitable human habitats in space.
Musk should probably get together with Bezos and concentrate on building an O’Neill Habitat in orbit around Mars. Then, once this orbiting infrastructure is in orbit, we can explore Mars at our leisure, without putting humans at risk of excess radiation exposure.
Exploration crews can move from the radiation-shielded O’Neill Habitat to the radiation-shielded underground Mars base, with the only exposure being during surface operations. The crews spend short periods of time on Mars and longer periods of time protected in the O’Neill Habitat.
This method, along with using an artificial gavity, radiation-shielded Aldrin Cycler/s as the means of transport between Earth and Mars, will reduce radiation exposure time greatly, compared to current plans.
Musk and Bezos should start out by building a demonstration O’Neill Habitat in Earth orbit. They can move it to a more preferable location, such as orbiting the Moon, after it is completed.
I have visions of O’Neill Habitats dancing in my head! That doesn’t mean much. Jeff Bezos has visons of O’Neill habitats dancing in his head, too. That could mean a lot! 🙂
No,it’s pseudoscience. It’s the mass of the atmosphere that is important.
If you divide the partial pressure by the gravity (Mars: 3.72 m/s^2) you get the amount of CO2 in kg/m^2. For the Earth is that 6.43 kg/m^2 (taking account for the ratio of the molecular weight of CO2 versus that of the air: 44/29), for Mars is the amount 164 kg CO2/m^2. The ratio of CO2 per surface area between Mars and the Earth is 25.5, the ratio for the total atmospheric amount is 7.2.
How about injecting algae in the atmosphere of Venus?
My understanding is too much sulphuric acid, not enough water unfortunately.
But there is a proposal to build cloud cities floating above Venus, normal Earth air in a balloon is buoyant in Venus’ atmosphere, and at around 50 miles altitude temperatures are bearable.
Sorry make that 50km.
Why bother ? RC Drones could be 10X more productive…Let them build what is needed THEN send Humans in about 100 years…..
The martian atmosphere is already 95% CO2. Gassifying the polar water and dry ice caps would probably not heat up the surface enough to be habitable. Only in the dark winter do dry ice slabs deposit alternately on the permanent north and south polar water ice caps. Some 25 to 30% of martian CO2 moves into and out of the atmosphere in this way.
Thus, the greatest benefit would come from evaporating the water ice. However the very dry martian atmosphere, even with its density increased, would soon lose most of this water. Atomic oxygen from photolysis of CO2 in the upper atmosphere can escape to space, so adding water to the air would risk losing hydrogen and oxygen in the same way.
Elon just wants to distract us from noticing Tesla is slowly going broke.
We take him seriously at our peril.
Yep..that is what happens when you smoke too much pot. You fry your brain. I don’t have a lot of faith in Elon Musk anymore after watching him implode Tesla and Solar City with all that hype. If you can’t make money with all those subsidies and freeloading off shareholders, then something else must be wrong.
True – why would anybody trust him on this crazy idea when he cannot reach his output target on EVs and his solar company is close to going broke? He should stick to his knitting, which he is not very good at!
Just when you thought the insanity could not get any worse the Green’s Icon, comes up with about the craziest idea yet conceived.
They are that mad to even think about transferring hundreds of thermonuclear devices across the planetary divide to heat up some CO2 on Mars. It would just evaporate into space on the prevailing solar winds from a then irradiated world making it, an even more hostile environment that it was prior to their lunatic idea.
Complete madness.
If the CO2 in the Martian ice caps was previously in the atmosphere why didn’t it prevent the planet from becoming frozen in the first place? Or maybe the whole greenhouse warming thing doesn’t work.
Shhhhhhh!
Apparently, according to the never-wrong Wikipedia, the reason Mars is not a hothouse caused by CO2 is that there are not enough of the other greenhouse gasses. It must be true
Nobody mention the obvious conclusion to be drawn, that Earth’s climate is the way it is because of the abundance of other greenhouse gasses (ie water vapour), or people might get the impression that CO2 does not have much effect on our climate.
Before that, Mars need a magnetic field generator.
Not much point to do anything to free up CO2 if it only blows away by the solar wind.
Well, build nuke hrnerators around the equator and connect them…. turning Mars to a solenoid.
Just by introducing a magnetic shield would start the process of atmosphere building and protect human settlers. I don’t have the math skill to calculate how much strength need and what is realistically generated by such a system. But I would prefer instead of a unstable pot smoking dude blow shit up there….
An idiotic idea. Looks like he wants more attention .

“Because CO2 is a potent greenhouse gas, the more CO2 Mars can release into the atmosphere, the warmer the planet’s surface will be. The effect is similar to how the fusion process inside the sun produces energy to keep Earth warm.”
————
I read that. I just have a hard time realizing someone wrote it.
Mars already has more CO2 in it’s atmosphere than the Earth does.
It’s what happens without paragraph organization.
The problem is that Mars does not have a magnetic field, any atmosphere you produce will just get swept away by the solar wind.
Several years back, I proposed building some induction coils in orbit around the equator of the Planet. Once energized, the coils turn the entire planet into a giant induction furnace. (You just have to think Big!) This could remelt the iron core of the planet and recreate a magnetic field. Now you can profitably reintroduce an atmosphere and start terraforming activities.
For reasons unknown to me, the crowd here at WUWT was not terribly excited with my proposal. As we see now, I was just ahead of my time. All I need do is suggest it to Elon Musk, and my idea will have a wealthy, visionary backer. Certainly my idea beats the hell out of nuking the hell out if the Martians.
I see a bar laying on the ground. Depending on its diameter, your idea just might clear it.
Yes! Finally, a positive review.
I hope some of the other regulars at WUWT will weigh in with their thoughts on my fabulous idea.
Well, we should probably explore Mars for signs of indigenous life before we melt it. It’s probably our best bet for finding life outside the Earth. That’s one good reason to go to Mars, whether we set up permanent residence or not.
The Earth’s ozone in the stratosphere comes from EUV/UV bombarding O2 to make O3, and thus makes the stratosphere opaque to EUV and UV-C and most UV-B, and protects surface life from this strongly sterilizing radiation. The O2 comes from Earth’s copious oceans.
Without sufficient water on Mars, there is no atmospheric oxygen to be converted to ozone on Mars (either thru biologic photosynthesis or non-biologic dissociation). Thus any terraformed Mars atmosphere would still suffer sterilizing EUV/UV to the surface.
Musk and his nuclear bombs.
Gates and his chalk dust.
Have any of these obscenely rich types ever been psychologically tested for a God complex?
Earth is a gigantic nuclear waste cooling pool. Ni kidding. Where does geothermal energy come from?
Formation of the earth involved a huge quantity of radioactive elements that concentrated deep below the surface and still release considerable heat (energy) by their decay. Yep.
Geothermal is in fact nuclear. Somehow inconvenient for the radiophobic crowds out there.
Now, this radiogenic heat represents a very small percentage of earth’s thermal balance.
However combined with the primordial heat, in a very poorly understood climate system, this factor should not be neglected specifically in projects where proposed infrastructures involve massive underground infrastructures.
Even more so on a planet without water circulation system, hot sources and other underwater volcanoes.
Just one more self-promotion sensational insane green public-relation attempt.
https://physicsworld.com/a/radioactive-decay-accounts-for-half-of-earths-heat/
Looks as if radioactive decay and primordial heat loss presently contribute about equally to earth’s internal thermal profile.
Why all the H-bombs? All we need to do is build a nuclear reactor there, which when activated begins a chain reaction sublimating the turbinium, thus releasing great clouds filled with water vaper and oxygen. Duh.
Get your ass to mars!
Here is some useful information about the Martian atmosphere:-
Hayne, P.O., Paige, D.A., Schofield, J.T., Kass, D.M., Kleinböhl, A., Heavens, N.G. and McCleese,
D.J., 2012. Carbon dioxide snow clouds on Mars: South polar winter observations by the Mars
Climate Sounder. Journal of Geophysical Research: Planets,117(E8).
On Mars it snows carbon dioxide during the southern polar winter. In this respect the atmosphere of Mars is unusual in that it is the main constituent gas that freezes rather than a minor volatile component, such as water in the case of the Earth, methane in the case of Titan and sulphuric acid for Venus.
Also on the northern water ice cap in boreal winter. A thin seasonal veneer of dry ice is deposited each winter, adding 1.5 to two meters to the permanent water ice cap. In summer, the dry ice sublimates into the atmosphere. Mars’ seasons are similar to Earth’s, because its rotational axis has a tilt close to our own planet’s (25.19° for Mars, 23.44° for Earth at present).
At present yes. But in the absence of a stabilizing Moon the axial tilt is much more variable, and at times the CO2 in the polar caps probably vaporizes completely, giving rise to the characteristic “layered terrain”.
John,
I did a bit more digging and found this on Wikipedia
Martian polar ice caps:-
That is a really nice point about the Martian north pole having a lower average elevation than the south pole.
We can assume that on average the north pole of Mars has a higher surface air pressure.
So the north pole of Mars is warmer than the south because of what? – surface elevation or atmospheric pressure?
I do so love comparative planetology.
Hard to compare when Mars’ surface atmosphere is wispierr than our stratosphere.
I assumed elevation. although of course air pressure is related to elevation. Our North Pole lies at Arctic Ocean sea level, while the colder South Pole on land at 9301 feet, some 800 miles fom the nearest open seawater.
