One of the shuttle crew's missions for this trip was to help in a renovation of sorts of the ISS, as they expanded it from three bedrooms and one bath, to five bedrooms and two baths. (I wonder how much that'll increase the property's resale value...and who the lucky realtor is who'll get to list it.)
Aside from other tasks such as completing spacewalks to clean and lubricate the ISS's solar alpha rotary joints, which keep the station's solar panels pointed at the sun for maximum production of electricity (talk about an argument in favor of solar power!), there was another experiment that caught my eye in the news stories I've read, and made me appreciate the gallon of water in my fridge.
Several crew members worked on a water recovery system to recycle urine and perspiration into drinking water. I'd tell you to go back and read that sentence again, but I'm betting that you already have.
I'll never look at a liter of Dasani, or a gallon of cheap Sam's Choice water, or even my not-so-delicious tap water in the same way again.
I wouldn't want to be on the team that has to troubleshoot the system and iron out its kinks before declaring it to be a working and fully functional system. Although one small sip should tell you if it's time to go back to the drawing board, or if the effort is a success.
The story in the link says that samples of the processed water were brought back on the shuttle for analysis before the station's crew can begin to use it. Thorough analysis, I hope.
It's amazing where we can fly...and what we can drink. Isn't it?
And oh, back to the "old hat"...
...during Endeavour's mission, it traveled about 6.6 million miles, and made 250 orbits around this big ball we call home.
Ridiculous numbers to fathom.
