Chinese Team Heading for Coldest Spot on Earth
LMCBoy writes "Dome A is the highest point on the Antarctic Plateau, and it has never been reached by humans. It is thought to be the coldest place on earth, and is certainly among the most remote. Yesterday, a team of Chinese explorers set out from Fremantle, Australia to reach Dome A and set up a robotic weather station which will monitor the local conditions for up to five years. The team is expected to arrive at Dome A in early 2005."
So what happens when the temperature (down to -90C) goes below the sublimation temperature of CO2 (-76C, if I recall correctly)? Does it just freeze out of the air? I'm sure these guys will be heating (and probably humidifying) their air supply anyway, but do they need to add CO2 to keep the breathing reflexes working right?
I've had this sig for three days.

Chinese Team Heading for Coldest Spot on Earth
Let me know when they find my girlfriend's heart.

Bleah! Heh heh heh... BLEAH BLEAH!!! Ha ha ha ha...
It's good to see the spirit of exploration is not dead. I am slightly puzzled by the story though. Why, if Australians are training the Chinese expeditioners, are they doing it in Fremantle?
That really doesn't seem a close match for the climatic conditions in the Antarctica. It may be far too easy compared to the high altitudes they are facing.
It would also be interesting to learn what challenges are involved in building those automated weather recording stations. How *do* they keep it running unattended for 20 years with batteries?

No, it's not.
Next question?
My sig is blank, I typed this by hand.
I mean, really. Look at all the things China is doing vis-a-vis science, technology, exploration, etc. They're like the Soviet Union of the 50's, involved in everything from space exploration to breaking records, to generally advancing its culture and playing a greater role in the world. Just a thought - don't grill me about their deficiencies.
A blog like any other.
China seem to be determined to push boundaries at the moment. Putting a man in orbit is no mean feat. Yes the US did it along time ago, but I don't see them doing it at all at the moment due to the shuttle grounding. Now pushing for the still unexplored regions of the world. I wonder if they have any deep sea missions planned for some time in the next few years. China has definitely decided that they have somethign to prove. The impressive part is that they aren't doing a bad job of proving it.
And this really ought to mildly concern people in the US. Yes the US already has done most of these things or something similar (they have a couple of Antarctic bases, one at the pole I believe). But that's the key point. The US has done such things, but doesn't seem to be expending quite the effort they use to on pushing boundaries of exploration and science. Increasingly it seems to be Chinese and Indians with the real fire to try and push ahead. And all the better I say. The US seemed to slacken off and grow complacent, so its about time there was some serious competition again.
Go China.
(Hopefully they can break new ground sorting out their political issues too)

The Chinese aren't going there as a big PR exercise. If you haven't noticed, the Chinese aren't big on grand, meaningless showboating: they do what they do because it furthers their long-term objectives, not because it wins them short-term positive press coverage.
The long-term thinking and objectives behind this sort of expedition is space exploration. If the Chinese can successfully establish a base in one of the least hospitable places on the planet, and overcome the physical, logistical, pyschological and other hurdles that such an endeavour involves, then they will have gained valuable experience and climed another rung up the ladder towards the eventual establishment of a populated lunar or Martian base.
They aren't going there for the scenery, they're going there to take some hard knocks and learn from them.

To an Australian living in Sydney, Fremantle is the coldest place on earth!
Couldn't they just air-drop the monitoring equipment? Parachutes, the whole nine yards. Almost like they do/did with the Mars rovers.
if they can survive 3 weeks in Jersey they can take anything else the Universe can dish out.
What, this far into the thread and you weren't expecting cracks about Jersey?

The coldest spot on earth is in a laboratory in Finland:

Dome A is the coldest naturally occuring spot.
Not trolling, I'm Chinese. Usually the US is fanatical about data-gathering. Thought hottest/coldest places on earth were visited and studied long ago.
Guess despite for all our telecommunications, earth's still pretty damn big.

An exam question on Momentum, Heat and Mass transfer: Is hell exothermic (gives off heat) or endothermic (absorbs heat)? Justify your argument.
Most of the students wrote proofs of their beliefs using Boyle's Law or some variant.
One student however wrote the following:
First, we must postulate that if souls exist they must have mass. If they do then a mole of soles can have mass. So at what rate are souls entering Hell and at what rate are they leaving?
Making the assumptions that once in Hell a soul cannot leave. Therefore no souls are leaving.
To determine how many are entering we must look at the different religions.
Some religions state that if you are not a member of their religion you will go to Hell.
Because there is more than one religion that states this and no one is a member of one of more religion we can postulate that all people, and therefore all souls, go to Hell.
With birth and death rates as they are we can assume that the number of souls in Hell are increasing exponentially.
Now look at the rate of change of volume in hell.
Boyle's law states that in order for the temperature and pressure to say the same, the ratio of the mass of souls and volume needs to stay constant.
Case 1: If Hell is expanding at a rate slower than the rate at which souls enter Hell, then the temperature and pressure in Hell will increase until all Hell lets loose.
Case 2: If Hell is expanding at a rate faster than the increase of souls in Hell, then the temperature ad pressure will drop until Hell freezes over.
So which is it?
If we accept the postulate by Theresa Banyan during my first year " it will be a cold night in Hell before I sleep with you" and taking into account I have not had sexual relations with her, Case 2 cannot be correct.
Thus Hell is exothermic- QED!

I'm an American businessman in the import- export business, so as you might guess, my frequent travels take me to many places around the world, on every continent. Anyhow, I wanted to share my experience in the "great" country of China.
;-)
:-P
;-)
Just to get it out of the way, I'm an American businessman too, that lives and works mainly in Tokyo Japan. I too travel all around the world, but so far business hasn't taken me to Antarctica yet. (Every continent, eh?) That said...
Anyways, when I stepped off the train from Hong Kong (which was no paradise itself, as that place has gone down the shitter since the Brits left) I was shocked. The whole place smelled like a combination of vomit and dog shit that had been left out in the sun for a day or so.
Reminds me of NYC.
And it was probably BECAUSE there was vomit and dog shit all over.
Yep, bingo, NYC! (Well, it's more vomit and urine, and less dog shit...)
People spit everywhere. Trash litters the streets. I found myself looking DOWNWARD much more than looking FORWARD when I walked.
Chill out, it's a cultural thing. If you're not used to it, the spitting can gross you out, but there are plenty of other things that we do that would gross out alot of other people. For example, not using a specialized tongue cleaner every day sorta grosses out the Indians. Using PAPER to wipe our asses is considered incredibly unhygenic (and in a sense it is) as far as most people in the middle east and asia are concerned. On the other hand, the thought of wiping our asses with water, USING OUR HANDS, grosses us out equally.
It doesn't help that their infernal language consists of abrupt rapid fire tones that is a cacophony for any human ear to bear. How do they speak and listen to that shit without going crazy all day long is beyond me.
If that's what you have to say about Chinese, you don't want to know what most people think of Yankee, Aussie and Kiwi English.
Anyways, Chinamen stink -- literally. There is no concept of personal hygiene whatsoever. Meetings with even top officials were hourlong sessions of having to endure hot sweaty bodies and rancid breath eminating from mouths missing a few teeth. Geez, at least use deodorant for crying out loud.
Americans stink too. It's not that rare that you'll run into a white american manager that apparently has never heard of deoderant. Soggy, dark sweat stains under their pits. I know many Chinese, and just like us Americans, there are dirty ones and clean ones, and nationality seems to have little to do with it. That said, Europeans have a much higher rate of having really bad BO, than Asians. Even with the deoderant, the Japanese seem to be able to pick up this scent, and will gag and puke behind your back. Again, this is all relative.
The hypocrisy, corruption, and double-standards from the highest levels of government on over are the norm at the same time China opens up to the world. Foreigners get charged as much as five times for transportation, lodging, food, and everything else.
Okay, I have to agree with this. There are a lot of back-stabbing double-standard corrupt "high" officials in China. This certainly has room for improvement. However, it's not that unusual in developing countries. Ever been to Indonesia?
Traffic is horrible. Rules are non-existent except for at traffic lights: red means to go fast, green means to go REALLY REALLY fast.
Ever been to Rome?
The Chinese people themselve are pretty apathetic and everyone just wants to get out of that hell hole, so you see smuggling rings shipping people out hidden in truck beds and ships, all too often with tragic results.
As far as the apathy, I wouldn't count out our own country. I guess we don't have people smuggling themselves accross the border to Canada though. Yet.

I'm no aviator, so I don't know why the team has to slog it there on foot. Why can't they simply drop in with a helicopter? I'm sure there's a simple reason I'm overlooking.

It appears that it takes liquid CO2 to make dry ice.
e _makers.html
From a google search.
Basically, dry ice is frozen carbon dioxide (CO2). CO2 is usually found as a gas -- it's what we exhale. To make dry ice, CO2 is compressed, and it liquefies at a pressure of approximately 870 pounds per square inch. The dry ice press then reduces the pressure, and part of the liquid CO2 sublimates (meaning it turns from a solid into a gas). The remaining liquid freezes into flakes that are compacted into solid blocks. The resulting dry ice is denser, heavier, and colder than ice made from water.
Here is a link to a machine that can make a block of dry ice in 60 seconds with just a liquid CO2 cylinder, and it costs less than 600 USD.

They are going there in Early 2005, and that peak summer in antartica. So temparatures will not be dropping below -50C. :)

if you happen to live in Taiwan.
Germany also doesn't deny their warcrimes unlike japan.
The chinese have plenty of reason to threathen japan. If they send a nuke or two over then it is just delayed justice and really no different then America invading Iraq.
No if you want to blame china for anything do it for their actions in Tibet. That is nasty enough for anyone.
If you are really serious about peace-loving nations not working together with more aggressive nations then america would be in total isolation right now. China is just saber rattling. Making sure that past war criminals do not get the idea they could do it again.
For the near future China has a booming economy that could only be hurt by going to war. They like being the maker of everything sold in the entire world. Why risk it all with a war?
It is roughly the same reason you hear nothing about Tibet. The western powers that be like having everything made cheap in China so China can go ahead with its own crimes as long as it doesn't do it accross its borders.
Money is a powerfull motivator for peace but peace can only happen when you remind people that they will loose if they are not peacefull.
America uses its fleets and the occasional invasion. China hold big parades and sends some parts of its fleet on excersises.
So far it seems that the biggest threat to world peace is firmly in the west.

On another note, does anyone know the approximate population of Antartica? Just curious how many people are camping out at those research stations.

Helicopters suck donkeyballs in thin air. They also guzzle fuel like their is no tomorrow. Check docu's on the artic. Ever seen a chopper in it?
Basically the area to be travelled in is to high, to far and to cold for helicopters to operate in.
However walking there is a proven techinique. It has worked for decades. Why develop a 1 use aircraft when you can simple hire some idiots^H^H^H^H^H^Hbrave men to haul your stuff there?

It's amazing the lengths people will go to show that the USA can or has been beaten. Even if the USA won, they'll concoct a reasoning that shows that they really lost.
I think there's an irrational hatred of the USA in general which causes people to want the US to fail. I don't waste my time bashing other countries highlighting all their failures, I want them to succeed. But I also want things to be kept in perspective and not sensationalized or overlooked. Saying that a country "can" do something that another country already has done is cheap talk. Let's keep it real- until they have, they haven't.
Your reasoning was pretty good, but it still was a stretch... it seemed like you were really reaching for something. Neither the USA, Russia, or China are going to build a "castle" on the Moon or Mars and defend it against exploration by another country. Space exploration is usually an area where countries help each other out even if they're enemies in another regard.
It is important to push emotions aside and keep things in perspective. Even if you don't like someone you should still be objective. Spinning the truth to make them sound like a failure only uncovers your bias against them.
