I am always striving to find analogies to explain the challenge of navigating a spacecraft more than 400 million miles and landing in an ellipse 40 long and 15 miles wide.
Well the head of space science for NASA – Ed Weiler came through for me (as he often does) with this one: It is like hitting a tee shot in Washington and making a hole-in-one in Sydney.
Thanks Ed. Helps history majors like me understand what rocket science is all about.
