Space Underwear/new state of matter

July 29, 2009

Remember Star Trek IV? That was the movie where they ended up time traveling back to the 20th Century and got stuck there, needing some transparent Aluminum to create a holding tank for a humpback whale. Some scientists have now created just that, if only for about 40 femtoseconds. They say it’s an entirely new state of matter, because they used a high-powered laser to remove one of the core electrons from each atom in a tiny area of Aluminum. This allowed X-ray and ultraviolet radiation to pass through uninhibited, effectively making the Aluminum transparent. (Via LiveScience)

There are many common luxuries that we take for granted on Earth, such as being able to wash our clothes. Unfortunately, in space you don’t have that luxury. Just going to the bathroom requires a highly sophisticated and technologically advanced toilet system. When astronauts wash their bodies they use special soap and shampoo that doesn’t require water. But in a microgravity environment where droplets of water can float around and destroy sensitive equipment, washing their clothes just isn’t an option. Unfortunately dirty clothes must be simply discarded. But apparently some Japanese scientists are working to fix that by inventing clothes that clean themselves… or don’t get dirty in the first place, depending on how you look at it. Astronaut Koichi Wakata, who just left the ISS on Endeavour, tested these new clothes during his 4 1/2 moth stay. It sounds utterly disgusting, but he never changed his underwear while he was there. The high-tech material actually kills odor-causing bacteria and absorbs moisture. He says that even after 4 1/2 moths of wear, they didn’t smell at all. This is yet another great example of how manned space exploration drives innovation and ultimately leads to technologies that are very applicable here on the ground. This could one day lead to clothes that literally clean themselves, eliminating the need for washing machines and dryers, which are energy and water hogs. (Via Universe Today)

In a related note, Universe Today also posted a set of great photos from Endeavour’s mission. Check it out.

That’s all I have time for today!
