[citation][nom]xxchocotacoxx[/nom]Good job making an ass of yourself. B-Unit is right: mettle is a word and it is a noun describing what a person is made of, usually meaning courageous. The word you're thinking of, however, is "meddle" and that is a verb with the meaning you described.As for the article, would it really benefit astronauts that much to be able to recycle their own urine? Instead of spending "hundreds of millions of dollars" trying to convert urine back to water, wouldn't it just have been cheaper to send up bottled water? I'm not well-educated on space travel so any insight would be appreciated.[/citation]
Ahh, maybe you're "write" on the meddle stuff. Oh well, not a real common word and, as always, I posted at like 5am. As for the sending up bottled water, no. It costs QUITE a lot to send up weight aboard the space shuttle. I'm too lazy to look up the cost per lb. but you can google it. It's ridiculous.
