The letter is from Mr. Russell W. Bassel to Senator Robert S. Kerr expressing his belief that space research and exploration should be under civilian agency rather than military control. Bassel argues that relying on the military to solve problems will lead to a fixed ruling class and a ruled class, and that the means used to achieve a goal are just as important as the end result. He emphasizes the importance of using space exploration for the betterment of mankind rather than for gaining power over others. Bassel praises Kerr for his defense of President Truman's actions and urges him to consider the implications of military control in solving mankind's problems.
