Personal Spacecraft

It's really a miracle that men and women work outside of the international space station, often for hours without the benefit of a tether. The spacesuits they wear are in fact personal spacecraft providing everything they need to survive in the harsh reality that is space. These suits maintain a constant 72 degrees farenheit when the environmental temperature is +250 in the sun and -250 in the shade. Extraordinary engineering.
