in relation to Mars...this is...
Paul Harvey referenced this story this morning:
Colder Than -- Mars! (Ithaca, NY) 01/15/04 - According to Cornell University News Service, the temperature inside the Gusev crater on Mars measured 12 degrees early Wednesday afternoon. In Rochester, New York it was just three degrees, according to the senior climatologist at Cornell’s Climate Center. It is day on Mars when it is night in the United States, but around the same time, January 14, temperatures in many northeastern cities were colder than Mars. ............................................. The view out our media window that we now have on the Martian landscape will be slowly seeping into our collective consciousness. Predictably, it will expand our conceptions of some things that are very deeply a part of our psyches - things like landscapes that appear in our dreams, the presence of robots in our lives, our very conception of what we call "life," and some things of which we probably still have no idea... As we come to better know our next-orbit neighbor, this thread can also be a place where we create a new bunch of aphorisms comparing "life" on Earth to "life" on Mars... It was as cold as Mars here in PA yesterday!

Don't you have to account for lower atomospheric condition on Mars to Earth? I wonder if they did that...

Good points Art, here's my Mars reference for the day.
With my roomate gone this weekend, the room has felt as desolate as Mars.

Air has alot to do with how various substance freezes on planets. For example, in the upper earth atmposphere, if the temperature was in 0 degree, water would be solid state. When the temperature changes to 20, water would instaneoiusly be vaperated, it would never even be liquid before going to gas state. My chemistry is rusty but that's why I remembered... I stick to computer programming b/c what I said still sounds bullshit to me

We will conquer mars....screw health care...screw poor people....lets take mars...
D-Day: War's over, man. Wormer dropped the big one. Bluto: Over? Did you say "over"? Nothing is over until we decide it is! Was it over when the Germans bombed Pearl Harbor? Hell no! Otter: Germans? Boon: Forget it, he's rolling. Bluto: And it ain't over now. 'Cause when the goin' gets tough . . . the tough get goin'! Who's with me? Let's go!

If you tossed some liquid water into 80 degree martian atmosphere it would freeze. Some of the water would rapidly evaporate in the dry thin air, the rapid evaporation would so cool the remaining water it turns into ice, then the ice would vaporize. |

Freezing point of liquids are a lot less affected by atmospheric pressure than are boiling points. Example: at sea level, water freezes at 32°F (0°C) and boils at 212°F (100°C). In Denver, water still freezes at 32°F (actually 32.00008, but you and I don't have anything to measure it that closely), but it boils at 195°F. If you bake anything, you notice high-elevation directions on the packages. The modifications are an attempt to compensate for the lowering boiling point.
The Martian atmosphere is sufficiently thin that liquid water cannot exist. Water ice vaporizes without melting when heated, similar to what dry ice (frozen CO2) does on Earth. If the Martian atmosphere were about 5 times thicker, liquid water could exist but only for a small temperature range.
