Gary Gindler, American Thinker
In 2005, American scientists deliberately sent a rocket to collide with a comet. After the collision, scientists were able to conduct a detailed analysis of the internal composition of the comet from the spectrum of debris ejected from the crater. It was a considerable achievement. But my friend working for NASA commented on this event differently: “You have no idea how many doctoral dissertations were thrown in the toilet yesterday.”
