Rare letter to his parents [Mr & Mrs Donald Chaffee, Wyoming, Michigan], beginning with family talk and his wife Martha before continuing with details of his work, 'We are well into our training program now and quite busy. We are studying geology, mineralogy, petrology (study of rocks), flight mechanics (orbits, etc.), physics of the upper atmosphere, digital computers, bio-astronautics, and astronomy, plus we fly quite a bit and take field trips. I was at the Cape to watch the Saturn launch a couple of weeks ago and the 5th and 6th of March we are taking a geology field trip to the bottom of the Grand Canyon.
