The setback of the failure of that apparatus really showed me something truly important, which was: If you don’t test it, it’s not going to work. People sometimes would say to you, “Well, why don’t you just take a risk and push the button and it will work?” It might work. And I think we learned that that’s cheating. Nature knows when you’re trying to cheat. If you don’t build it right, it won’t work. So that turned out to be extremely important to me later, because when we were building the satellite, we knew that we didn’t have a chance to do it over, and so it darn well better work. So it gave me the heart to say, “You know, if we don’t test it, it won’t work.” That was pretty important at a time when the project that we were doing was running out of money and time and we might not be able to test it properly. So I finally said, “Well, you know, we’ve got to test.” And my colleagues at NASA, the engineers, they know this. They know if you don’t test it, it won’t work. They’re very determined. But it was really important for me to back them up and say, “Yes, we will test it.” So it did work and then it did wonderful things.
