Looks much prettier as untouched nature.

Just kidding, I'd love you to have NASA's budget if you can promise me not to become as shitty as NASA. Bureaucracy is killing the agency and sucking up loads of that (now reduced, thanks Obama!) budget money.

It does work that way. You give me 65 kilotons of plutonium, I'll add 65 kilotons of antiplutonium.
Checkmate trolls.

Unfortunately, it doesn't work that way. Hence the trollpic.

Lemme just calculate this shit for y'all. If we take that we'd like to heat mars up to 5km deep (which is realistic enough), we'd need to heat up 4.213×10^8 km^3 of soil. According to [1], let's use 1.1 MJ/m^3. That amounts up to 4.634×10^17 MJ. Now, that's a fuckton of energy.

2.816×10^10 watts is how much mars receives erry second. Wanna calculate further?

People are constantly underestimating the amount of joules required to warm up trilions of tons of permafrost by just one degree kelvin.

Yeah, it's just that one could distinguish a person as a slav just based on looks. You could nuke poland or russia, but you couldn't kill all the slavs in other countries if they are smart enough not to raise hand if a nazi asks 'are there any slavs here'.

Fora je što imaš šanse da upadneš sve dok imaš scores preko minimuma (gledaju ti TOEFL i SAT više nego srednju). Jebiga, ako i ja ne upadnem, u još sam goroj situaciji nego ti. Ima i ovdje dobrih profesora, meni inače predaje profesor fizike koji je prije par godina otkrio neke potpuno nove formule u području magnetizma, zvali ga u USA da odradi neku prezentaciju + nagradu da dobije, on ih poslo u PM i reko im da dođu oni njemu ako ih šta interesuje. Nećeš ostat' glup, al nećeš baš ni proslavit se kao prvi čovjek na marsu. Takav grah pao.

How about a comparison - imagine all amount of iron ever mined in human history. Yeah, couple hundred times more. I mean, sure, we could theoretically find an asteroid with a large % of uranium ore, somehow slam it into a huge hole in mars and expect it to work. I have no fucking idea if it would, in any amount of time. Again, I'm by no means qualified, this is purely my own speculation, AFAIK it's completely impossible.

Jesmo se našli na 4chanu u pm. Diplomski, malko ambiciozno jeste, al imam dobre preporuke, rezultate s takmičenja, sve te pizdarije. Vrijedi pokušati, ako ništa, uvijek ima grad school.

I was joking, nukes are better than antimatter that my colleague suggested - they are radioactive, which is what runs our own core, if I'm not mistaken. It's just that you'd need billions and billions of tons of uranium or plutonium to make it works. Seriously, the amount is ridiculous, not to mention getting it 3k kilometers into planet's core.

This. As far as I can see now, we'll first try to raise air pressure and temperature using CO2, which will both plummet after we introduce bacteria into environment . It'll take some careful planning to balance it all out to get to a human acceptable levels. Actually scratch that, it's a fucking nightmare to balance it all out. We need CO2 for temperature and pressure but eventually we want CO2 of <1%, temperatures bigger than -40C and fucking oxygen. COmputer modeling it is, but we don't even have the starting conditions.

>>4020077
Unfortunately, I'm aware of that and worse, I have no fucking idea. Magnetic field is what we need to establish there and that, right now, is completely impossible.

>>4020085
tl;dr we are screwed.
Inurdaes has a good idea what we should do; make it economically viable (god damnit) to go there. After first cheap LEO launch will come asteroid mining with profits and Mars colonization should follow.

Or yeah, I could get Bill-Gates rich and do all of it myself.

>>4020029

Damnit.

Inurdaes je iz Melbourne (?), a ti serbian guy?
Vi ste sretni, ja sam još u ovoj shithole, ali se sljedeće godine nadam upisati na MIT Physics, imam dosta dobre šanse tamo.

Let's not derail the thread further.

What we need to have in order to stop speculating and start modelling are accurate information about the surface and air, which means a fucking landing and checking the soil and air in a lab. Until that has been done, all the terraforming talk is in face sci-fi.

Naravno ako već pretpostavljaš infinite monies, možeš da vadiš nitrogen iz tla. It's all about efficiency. Alge bi bile neloša ideja, ili neke druge anaerobne bakterije koje bi co2 pretvarale u o2, ali to je već too far fetched.

>a real source

Man, I'm all for Mars colonization/terraforming but a fiction novel is always a crappy source, especially if you look at the time it was written and all available data at the time.

>made a thread today
>flamed to death

Sup guys.

OP, it ain' continuous because you have 2 possible states - up and down/ head and tail. That was my (apparently) correct reasoning.
