Fabulous!

That doesn't make sense, Space is cold yes but it's also empty so you only lose heat from radiation.  I would think that the rate of heat loss encountered on a windy night in Antarctica would be much higher than that found in space.  The same way that it's much worse to be in cold water than cold air of the same temperature, and in a still fluid rather than a flowing fluid.

Read TFA.  It's not a space suit.  It's clothing that they wear inside.  The reason they test space stuff in Antarctica is that it's a good example of the close quarters, isolation, and other psychological stresses.  And this clothing is loaded with sensors to measure physiological response to stress.

Space doesn't have a temperature. It's a vacuum.

Yes, for example:  http://www.space.com/21987-how-nasa-spacesuits-work-infographic.html

Note the "liquid cooling garment to keep the astronaut from overheating" bit.

Similar to the chiller suits that maintainers wear when servicing aircraft sitting on blazing hot runways in Iraq and Afgh. They may also drink Tang. Not sure what came first, but it seems like a tandem development happening.

No, it's only *mostly* a vacuum.

I was just being an annoying pedant.
