explain biosuits to me. you tell me it is enough for the astronaut to just go out there in vacuum with nothing but a spandex on and they'll be fine?
what about direct sunlight exposure? will that thin layer of spandex be enough to protect the wearer? or extremely low temp of space?

I read the MIT article but I still don't understand how temperature will be managed and I find it difficult to believe that sweat will be enough to regulate the body temp under such extreme environment.
