The Space Show

The Space Show focuses on timely and important issues influencing the development of outer-space commerce and space tourism, as well as other related subjects of interest to us all.

Guest: Dr. Harvey Wichman
Dr. Harvey Wichman was the guest for this special Space Show program. As Dr. Wichman is an expert in human factors for space travel, suborbital as well as orbital, plus since he is the director of the Aerospace Psychology Lab at Claremont McKenna College having done various human experiments simulating space flight and cabin condition, we spent a significant amount of time discussing the wide range of factors that can and do impact people in space. Dr. Wichman was superb at breaking down what factors concern suborbital, orbital, and long term space flight. We made comparisons to humans in airplanes and at different altitudes and pressures. We discussed radiation and the impact on men and women. We even delved into the world of the rather "unmentionables" on the radio as we got a graphic description of using a space toilet and treating human waste. We even got a crash course on how vomit in special bags were one to experience space sickness. Dr. Wichman also stressed the importance of minimizing the G-force for humans, especially tourists, both in ascending and descending in space travel.. Pulling more than 2-3 G's was most likely unwise and even risky. He also talked about the importance of making sure space travelers got their money's worth for the trip, suborbital or orbital. He talked about the need to have very reliable cabins so that passengers did not need space suits but if such cabin pressurization systems were not sufficiently reliable and redundant, then he, like other guests, talked about the necessity of using space suits though they will be very uncomfortable and might cause the loss of paying customers. He also said it was very important to have the passengers experience Zero G and not a roller coaster type of Zero G. He mentioned loosely fitting straps or ways to allow the passenger to float free and if for whatever reason the passenger could not return to his seat and strap in prior to reentry, the cabin would be designed with safe zones in it so the passenger could lodge into a safe zone and safely "ride out" the return to Earth. Lots of other interesting design and requirements for humans in space are discussed during this interview so don't miss it. Dr. Wichman is one of the top authorities in the world on these subjects so I know you will want to hear what he has to say, offer, and suggest, especially given his commitment to see space tourism flourish as we become truly space-faring. You can send your questions or comments to Dr. Wichman to me at drspace@thespaceshow.com and I will forward them to him for a prompt reply.

About our guest...

Dr. Harvey Wichman
Professor Harvey Wichman received his B. A. and M. A. degrees from California State University, Long Beach and his Ph.D. in experimental psychology from Claremont Graduate University. He was a member of the founding faculties of both Delta College in Michigan and California State University in San Bernardino. He is Professor Emeritus at Claremont McKenna College (CMC) and Claremont Graduate University. He is currently Director of CMC's Aerospace Psychology Laboratory. Trained in both neuroscience and social psychology, he conducts research on the effects of working and living in severe environments. As a Fellow of the American Council on Education he spent a year at the National Institutes of Health. As a Sloan Foundation Fellow he worked for a year on the design of the International Space Station with Rockwell International. He is the author of the book Human Factors in the Design of Spacecraft, and has published articles in journals such as the Journal of Personality and Social Psychology, Space Life Sciences, Human Factors, and Aviation, Space, and Environmental Medicine. In addition to work with NASA and the Jet Propulsion Laboratory, Professor Wichman's space research has involved designing passenger compartments for civilian space flight on re-useable McDonnell Douglas Aerospace (now Boeing Aerospace) rockets for both orbital and sub-orbital flights. Most recently the same design activities are being conducted for the new two-stage Universal Space Lines rocket called the Space Clipper. The CMC Aerospace Psychology Laboratory has conducted research in simulated space flights and is currently developing a space flight simulator for the space museum at Alamogordo, New Mexico. In the field of aviation, Professor Wichman studies passenger misbehavior aboard airliners (he holds commercial pilot multi-engine, flight instructor and instrument flight instructor ratings). In social psychology he studies the variables associated with forgiveness.
