[url=http://curiositywatch.com/curiositys-first-weather-readings-are-in-you-could-probably-survive-for-some-minutes/]Source[/url] [quote]I always thought of Mars as a really hostile planet, making it impossible for a human being to survive longer than a couple of seconds without a spacesuit. I mean, there’s almost no atmosphere on Mars and the planet is much farther away from the Sun than Earth (1.5 AU). But then I saw the first temperature diagram Curiosity sent after her landing on Mars, recorded by the REMS instrument (Rover Environmental Monitoring Station). REMS collects data about wind, pressure, temperature, humidity, and ultra violet radiation. [B]It’s cold, but not super cold [/B] This diagram shows air temperature (blue line) and ground temperature (red line), covering Sol 10 (Aug. 16, 2012) to Sol 11.6 (Aug. 17, 2012): [img]http://curwatch.s3.amazonaws.com/img/temperature-mars-2.jpg[/img] Image source: NASA Air temperature is peaking at -2° Celsius (28° Fahrenheit) and going down to -75° Celsius (-103° Fahrenheit) at night. That might sound pretty cold, but let’s take a look at the lowest temperature measured on Earth. On July 21, 1983, the Vostok station in Antarctica recorded −89.2 ° Celsius (−128.6 ° Fahrenheit). 1 And in Siberia, temperature regularly goes down to −50° Celsius (−58° Fahrenheit) – and still there’s people living there. [B]The pressure’s (not) on[/B] So we might survive the cold temperature for a while. But it’s not only about temperate, but also about atmospheric pressure. And that’s where the problem begins. Here’s the exact readings from Curiosity’s REMS covering Sol 9.5 (Aug. 15, 2012) to Sol 13 (Aug. 18, 2012): [img]http://curwatch.s3.amazonaws.com/img/mars-pressure-2.jpg[/img] Image source: NASA Mars’s atmospheric pressure was fluctuating between about 6.9 millibars (690 pascals) and 7.8 millibars (780 pascals). This means that the atmospheric pressure on Curiosity’s landing site is only about 1% that of Earth. And that’s just too low for a human body to survive. [B]You would not explode immediately and your blood wouldn’t begin to boil instantly, but you probably wouldn’t stay conscious very long. [/B]2 So in theory, you could stay alive for a couple of minutes – but you wouldn’t be in very good shape after that experience, because the Sun’s UV radiation goes down on Mars almost unfiltered. Also, you should not try to hold your breath on Mars as this will most likely damage your lungs.[/quote]
What fucking sort of scientists measures temperature in degrees of Fahrenheit?
American Scientists. Alternatively, they could've just converted it from the actual data for the graph
So it is, in fact, a really hostile planet I mean not compared to venus or pluto I guess but we ain't gonna be fucking around there setting up cold stone creameries in the near future informative I suppose but I don't see the point of this article
[quote]Air temperature is peaking at -2° Celsius (28° Fahrenheit) and going down to -75° Celsius (-103° Fahrenheit) at night. [/quote] I'd imagine that would be pretty uncomfortable for settlers.
You have the wrong graph for pressure in the OP. Pretty cool though. With the ground temperature at 37 F, liquid water could flow daily.

[QUOTE=Awesomecaek;37392709]What fucking sort of scientists measures temperature in degrees of Fahrenheit?[/QUOTE] None of them; check the graphs, they're all in Celsius. The author just added them in as Fahrenheit, presumably for ease of reading.
