Why Explore Space? A 1970 Letter to a Nun in Africa | Roger Launius's Blog. Ernst Stuhlinger (1913-2008) Ernst Stuhlinger wrote this letter on May 6, 1970, to Sister Mary Jucunda, a nun who worked among the starving children of Kabwe, Zambia, in Africa, who questioned the value of space exploration. At the time Dr. Stuhlinger was Associate Director for Science at the Marshall Space Flight Center, in Huntsville, Alabama.
Touched by Sister Mary’s concern and sincerity, his beliefs about the value of space exploration were expressed in his reply to Sister Mary. Dear Sister Mary Jucunda: Your letter was one of many which are reaching me every day, but it has touched me more deeply than all the others because it came so much from the depths of a searching mind and a compassionate heart. First, however, I would like to express my great admiration for you, and for all your many brave sisters, because you are dedicating your lives to the noblest cause of man: help for his fellowmen who are in need. The situation which we are facing today is similar in many respects.
