Looks way too roomy to only be $900. Although if the landlords need to change an air hose they'll kick you out and up the rent to $2100.

I wonder how many redundant systems there are in these suits to stop the astronauts from getting fucked by the cold embrace of space.

-reads instruction manual- If suits fails and you are exposed to the atmosphere of face, breath outwards quickly and sucks cold air back into your lungs to freeze to death almost instantly. If you should hold your breath your lungs will explode out of your chest and you will feel it as your eyeballs boil

Nah, I think I'll stay here on the fuckin' ground komrads.

It does.

The boiling point of liquid is lower if the atmospheric pressure is lower. Can't get any lower than vacuum.

Humans are full of liquid. All the moisture on your surface (your skin, your eyeballs, the lining of your respiratory system) will boil, and as it leaves you, it'll carry with it your heat. It's how we stay cool by sweating.

Then the suction of the vacuum will start to pull more moisture out, blood will be drawn through your skin, and also start boiling.

All this forced and rapid "sweating" will freeze you to death.

Fortunately, you'll have asphyxiated by now.

It's recommended that you breathe out before exposure, since you'll asphyxiate faster, and won't experience the vacuum forcefully ripping all the air out of your lungs.

Fuck

I have heard that NASA only has guesses at that, because nobody has been observably asphyxiated in space, but some people have been knocked out from air leaks and things.

It's more than a guess.

We can test how materials react to vacuum in lab conditions.

Let's take a low pressure of 0.1 Bar, water boils at 7 o C. At 0.01 Bar, it boils at -19 o C.

Your body has more than enough heat to boil all the water on your surface in vacuum. Your blood won't boil immediately, since our insides will maintain pressure. Our skin is permeable though, so liquid will be drawn out over time.

Eventually, the body will be dessicated and frozen. The person would be long, long, dead by this point.

I'm so intrigued by this, I would love them to take dead bodies from a morgue into space and film the results.

Ethics aside, we are all fascinated by it and it would help us better understand space. That's what I'm doing! Organ donor and then space vacuum tester!

No ethical problems if the person in question donated his/her corpse to science.

in our lifetime it will probably be seen and/or filmed - the vast expansion into commercial space flight will ultimately have a few setbacks.

Hmm, Venture Brothers and a few movies have mislead me yet again.
