a better earth

I re-read the letter from Dr. Ernst Stuhlinger, the associate director of science at NASA's Marshall Space Flight Center, in response Sister Mary Jucunda's query. Why should we spend billions of dollars on space research and exploration when there are so many children were starving on Earth? Stuhlinger's missive is long but I believe fair and balanced. In fact, he argues that space missions help everyone on this fragile planet. His message is hosted on Letters of Note blog. It is particularly interesting to me that he touches on international cooperation. Prophetic, for 1970.
