Mir To Crash Into Pacific 188
b0z writes "According to an article on Yahoo! the Russians are planning to dump Mir into the ocean in February. According to the article, the $40 million that MirCorp has raised is not enough to save Mir. Also, it is noted that Mir has been in use much longer than the engineers that made it intended." Of course, I'll believe this when I "see" it - the saga of Mir continues.

Note the volume of water in the ocean. Note mass of space station. Note delta T when station hits water.
Obviously, if there happens to be any sea life around where Mir hits, its not going to be around for long. But we're talking about the middle of the Pacific Ocean here. The concentration of life is not high. The amount of life killed or affected by Mir's landing will be low. Mir will have no lasting effect on the surrounding ocean. Any temperature elevation will be unnoticeable after a few days, probably a few hours.
As for warm water from factories effecting ecosystems:
In those cases, we are talking about lots of warm water, over a long time, into rather shallow and confined bays with high concentrations of life. Big difference.

We can point the jets at the sun all we want, but there's still that whole gravity thing to contend with. It's how objects either stay in orbit or fall back to earth.
It would take a lot more ooompf to get Mir to the sun than it would be to push it past critical orbit decay. Consider, getting to the sun would require competing not only with our gravity, but the moon's, venus' and likely Jupiter's. It's not just point it at the sun and let fly. Gravity has a nifty way of making satelites slingshot around larger bodies.
So what would we need? A booster to get it out of Earth orbit with enough juice left over for something of that mass to navigate though the solar system without orbiting something else. Not trivial. And probably more that $40 million and much riskier than the current plan.

Mir's orbit, already decaying naturally because of atmospheric drag, will be reduced to 80 km (50 miles), causing the space station to enter the dense layers of the atmosphere where most of it will burn up. The remains of the station will then fall in a sparsely populated region of the Indian Ocean.
"Everything will go according to the laws of physics: the station will burn and break apart," Blagov said, adding that the entire operation would take several days.

Puleeze. Mir is a pretty big chunk of metal as metal chunks go, but it is insignificant when compared with the mass of the ocean. Try heating a spoon to red hot, and plunking it into a glass of water. Sure, the water around it sizzles for a second, then the spoon is cold, and so for the most part is the water in the glass. Do the math comparing their mass and the delta T. If you have some thermo classes, it's pretty evident that Mir won't do squat to raise the temperature of the earth's oceans.

The political/economic system doesn't matter much. If you give smart people lots of resources, they can build some really cool things.
It also goes to show the major failing of ALL political systems - resources will get allocated according to political process rather than according to logic and common sense.
If russia was truely communistic, and truely believed in "the people" (afterall, isn't the basic tennant of socialism that the welfare of the people is paramount?) then maybe they would have allocated resources to raising the standard of living and producing enough food and goods for their entire populace - rather than trying to shoot cool toys into space and engaging in an insane arms race?
Of course the same could be said of the US. Armed forces Generals have been saying for years "We have enough nukes, we can stop making them" yet every year congress allocated more money to making new nukes.

I bet their won't be any part of Mir intact enough for pressure to be an issue
The end result - radioactive contamination will poison the ocean.
Any potential radioactive contamination will be far less then the contamination from all the nuclear tests that were conducted in the Pacific.
If they have to get rid of Mir by dropping it into the ocean, then they should damn well get rid of the hazardous material it contains first.

Oh, please! Let's imagine that when Mir hits, it is at the same temperature as the surface of the sun (5700 K), while the ocean where it lands has a temperature of 280K. Let's say that Mir is made of steel with a total mass of 100,000 kg.
Heat capacity of steel = 447 J/(kg*K) , heat capacity of water = 4169 J/(kg*K).
So the heat energy supplied by the station is (447)*(100000)*(5700 - 280) = 2.42*10^11 J. Dividing by the heat capacity of water, we get a result of 5.8*10^7 kg*K.
In order to calculate a temperature rise, we need to decide how much of the ocean's volume to consider. For the first calculation, consider a cube of water 100m on each side. I hope you will all agree that this is an absolutely tiny fraction of the entire Pacific ocean.
The volume of water in this 100m cube is (100^3) =10^6 m^3, and the density of water is 1000 kg/m^3. Therefore, the mass of water in this cube is 10^9 kg.
So, (deltaT)*(10^9 kg) = 5.8*10^7 kg*K
deltaT = 0.058 K (or 0.10 degF for Americans).
Now take a look at http://www.icess.ucsb.edu/geos/1112.html [ucsb.edu] , a page studying the El Nino phenomenon. Look at the satellite photos on that page, and figure out for yourself how much impact a 0.058 degree temperature rise in a 100m section of the Pacific ocean is going to have. Also note the section in the text which says "On warm sunny days, the surface waters can heat up by as much as 1-2 degrees C during the daytime hours".
Granted, any fish which happens to be at "ground zero" is going to get cooked, but the ecosystem is going to be completely indifferent to the event (at least from a thermodynamic perspective).
p.s. The environmental damage caused by industrial cooling-water is real. However, there you have a continuous source of heat energy rather than a one-time addition of a heated space station.

Anyway, even if Mir gets a good dose of beta radiation (free electrons for the uninitiated), any charge that builds up will just be 'absorbed' by the atmosphere. You probably get more extra electrons form solar wind in a second than you would form Mir no matter how long it had stayed up! As for alpha particles I think their only dangerous if their fast moving.
