I agree somewhat with the last 2 post, BUT,, the temp gun, and the cat scan were invented here, on earth. They just used them on the moon/ outer space.
Im not so convienced on "global warming". Global warming is a trend in temps that happens here on earth. Theres records to prove it.
I DO apreciate the satellites, and they are a positive, USEFULL product of NASA I suppose, but like I said, we should understand whats on and beneath our planet first. It just seems more promissing for the greater good to me.
