I wonder what caused it to cool, and if it can be jumpstarted.

I'm gonna look into what may have caused it to cool when I get some time. I imagine it would take a crazy amount of energy in the form of heat to get it back to rolling again. I think the solution can be found if we really learn all we can about the red planet. There must be a way to extract some energy from the planet and target it at the core in the form of heat. We probably would need a solution to the gas problem of the atmosphere before embarking on this task.

It would be awesome tho.

Earth is probably headed for the same fate. Polar caps melting could be from the core losing heat (a unidentified type of global warming). Jumpstarting could probably be done in the form of a light nuke or something (if it didn't blow from the pressure).
Just my weird thinking at hand.

I'm thinking that we probably need a team of nuclear scientists and depending on how advanced nuclear science is ( I have virtually no knowledge of nuclear reactions all my related knowledge is of chemical reactions) they could create the elements needed from the elements found on Mars. Once the Scientists have created enough radioactive isotopes. (because nuclear reactions between elements can form other elements unlike chemical reactions which bond different atoms together) then we would need to have a way to plant those isotopes deep within the planet.

After the isotopes are planted deep within the planet we may be able to employ your idea and set off some nuclear reactions to get it really hot down there again. While the nukes start up the initial heat the radioactive isotopes could keep adding to the heat as they decay to keep it hot for millions of years to come.



Or maybe we need to set off the nukes first then plant the isotopes later. Idk

You said a trip to mars would be dangerous because of the radiation. You would actually be exposed to more radiation on the moon because the atmosphere there is negligible compared to mars. The only way you would be exposed to less radiation is if you cut the trip short, but you cant expect a 3 week visit to the moon to prepare you for a trip to mars. Not when the ride there alone is 80 days.

That's the whole point. You can come back. You face radiation on the way to mars and on the way to the moon. You face radiation on mars (no matter the amount, as long as it's enough to kill you, who cares?) and on the moon. Difference is, with the moon you can come back. Just like you can come back from the space station. That's big. You're just being argumentative. :smt003

The only way the moon can become a stepping stone to mars is if you have people actually stay on the moon as long as they would be away from earth on a visit to mars. During the test run if they get tired of it they can get back home relatively fast. The thing is, if you get sick of being away from the earth on a trip to the moon, then it will not make a lot of sense for you to go to mars which is of course much further from earth.

As I said, it's a stepping stone technologically. A moon base is also more feasible, and in the long run (a.k.a waaaaaaaaaaay before anyone could possible "terraform" mars), the moon could serve as a launch pad for other space missions.

Beasty said:
During the time away on the moon they would be exposed to more radiation than they would be on mars because mars has more of an atmosphere. Of course you would still need protection from radiation on Mars but that doesn't change the fact that you would be exposed to less of it.
The atmosphere of Mars does not provide sufficient protection from radiation by any stretch but in contrast to the moon some is better than none. Score one for Mars

Okay --instead of dropping you from the roof of a 140 story building, I'll drop you from the roof of a 130 story building. Score one for the 130 story building.

You have jokes about the Atmosphere being breathable on mars? The atmosphere there is mostly carbon dioxide. The molecular formula for carbon dioxide is CO2. One part Carbon two parts BAM. :smt066

So tell me why that's not a huge plus in comparison to the moon......I'll wait.

Last time I checked it was possible to synthesize CO2 into oxygen because its actually made of oxygen. It is also impossible to create it from nothing. So feel free to explain why the atmosphere on Mars is not a huge plus in comparison to the moon.

You mean like the oxygen in the H2O on the moon? Do you even science bro?

Beasty said:
Also you seem to understand that having less gravity is a challenge to human health. So explain why you think it's not a plus for mars to have more gravity than the moon.
Click to expand...

Don't forget the trip there, and don't forget the lower gravity on Mars -- which you can't come back from. Low gravity for a few weeks, vs low gravity with no return. Tell everyone which you would choose, so they can laugh at you.

Musk is talking about having oceans on Mars which would require the atmosphere to be compressed. I don't know how he could compress the entire atmosphere, but at least mars actually has an atmosphere to compress. If you read my previous posts in this thread you would know that I already understand that there must be a certain pressure for water to remain a liquid under a given temperature. So why bore me with the redundancy of needing a space suit?
Click to expand...

Terraforming mars is science fiction. If you think Musk can do that, I really don't know what to tell you. Mars is a planet dude. A planet.

Beasty said:
Another point goes to mars for actually having much more air molecules to compress to begin with. Even if the entire atmosphere can't be compressed its still a plus that mars does have more air because Musk could easily build buildings with compressed air systems.

I don't think we should abandon the moon altogether. I just think you should take up your ambition for the moon with the government rather than Musk.

Lastly to address your comment about giving Technology a trial run on the moon. What tech are you talking about? The suits get tested at the space stations. Any technology for the space ships must be tested in flight because that's where its going to actually be used.

Jeesh -- all I can say is it's a good thing you didn't make science your vocation.
 
musk talked about going to mars.
obama talked about going to mars.
bush talked about going to mars.

What's with this constant "end of administration" talk of going to mars? I'll tell you what it is -- it's bullshit. :mrgreen:

Lol.......I'm sure that's all you can say. Anyone could have came up with that. Bottom line is that you don't have logic to support your position that the moon is a stepping stone to mars or that mars is not more hospitable than the moon.

You have no idea what my background is. I've worked on technology that's used in flight. Miss me with your hubris.

Have fun using your water for oxygen. I can think of other uses for water.

A dangerous trip you can return from, vs a dangerous trip with no return.

A trip that's been done before, vs a trip with many "unknown unknowns"..

A trip with a payoff of helium three, great science & tourism that the rich would drool over, vs basically a "one off" suicide mission.

Okay - you got me on "logic". :smt083 You win the pork chop, bro. :mrgreen:

Your unproved assumption is that you know more about business and science than musk.

Lol

You can drop them jewels any day now. :smt005
 
Elon Musk says SpaceX is developing a 'bleeding' heavy-metal rocket ship. Making it work may be 100 times as hard as NASA's most difficult Mars mission, one expert says.

I think Musk plans to heat the polar caps on Mars. This would release more CO2 into the atmosphere and increase the air pressure, perhaps to a level that would allow liquid water to flow.

I wonder if, at least in theory, Musk has figured out a way to compress the atmosphere in smaller, man made areas rather than the whole planet? Say, areas the size of a small to medium city. From what I know (which is very, very little) that would seem more practical.

Turns out that they are thinking about heating the polar caps. This is a good comprehensive video. Start 8min in.

The Andromeda

It will collide with the milky about 4 billion years from now. It's the closest spiral galaxy to us at 2.5 million light years away.

A galactic year is about 250 million years. The last time the earth was in this position in the milky way the dinosaurs were just beginning to walk the earth.
