Shuttle Safe to Launch Friday, NASA Says

I was surprised to find an article that would so easily link to what we are doing in our physics class. This article is about one of the fuels cells having erratic readings in the coolent system. They have analyzed the problem and have assessed that it is not bad enough to stop the shuttle from launching. The weather looks good for the launch to be coming up soon.
I'd just like to say that everything in the space program has to do with physics, without knowledge of what was going to happen beforehand using mathematics, there's no way that they could send anything into space. I think that this particular article deals with what we have learned about margin of error. In physics, a scientist must always account for his tools margin of error in taking their readings. This article shows a fuel cell that has been taking erratic readings in the coolent system, but they are going to launch anyway; therefor they must know that their margin of error is still within what is good to launch. Also since the measuring device is taking erratic readings, it can be assumed that it has a greater margin of error than one that is functioning normally.
Another aspect of the space program is the measurement of distances to be used in the mathematics to make the whole program work. That is what the space program is about, and it basically desribes what physics is.
