QUESTION: I am doing a project in which we build a model of the place we're going to live on Mars. I am in charge of personal hygiene, ergonomics, and exercise. I was wondering if there were any facts that would affect these categories in any way about Mars. ANSWER from Jack Farmer on July 21, 1997: In responding to your question, I contact Dr. Marc Cohen, a colleague in the area of human space exploration who suggests the following for information: Contact for information: Man System Integration Standard (MSIS) Manager Code SP3 NASA Johnson Space Center 2101 NASA Road 1 Houston, TX 77058-3696 Important references: Connors, M.
