We welcomed back Dr. Vadim Rygalov and for the first time UND SpSt graduate student Annie Wargetz to discuss her exceptional research regarding dietary & nutritional requirements for deep space mission astronauts. Using Earth models such as submarines, extreme habitats, historical explorations, the Antarctica habitats, plus the ISS, our two guests shined an important light on a seldom discussed set of issues regarding astronaut nutritional challenges for deep space missions. In the first segment of this two hour discussion, Dr. Rygalov introduced the subject to us & then he introduced us to Ms. Wargetz to discuss her work, research, & findings. Many topics & issues were covered in this segment ranging from a broad discussion about extreme historical exploration missions, Earth habitats, submarines, the ISS, & more. We learned what is known about deep space nutrition & astronaut food, eating, & caloric issues. Annie talked about what we have learned from the different terrestrial models referenced in our discussion, plus many other issues presenting challenges such as food preparation, the lack of anything fresh, the lack of color in food, & the use of processed & chemical foods as is the standard for today. She also talked about plans to mitigate these challenges on deep space mission flights. Bringing fresh vegetables, seeds, even small animals on a mission are plausible & were addressed. One caller asked for a definition of a closed life support system. Both our guests went into detail about this, including partially closed systems, bioregenetive systems, physical/chemical systems, & hybrids. Vadim brought us current with our existing technology & what is likely to be available in the near term. This is a comprehensive discussion pertaining to deep space environmental systems. We started the second segment with our guests answering a question from the firsts segment about married couples in space. Don't miss their response & what Vadim said was his choice for the first crew for a deep space mission & why. Mars 500 & Biosphere 2 were mentioned in their response. Two other issues that were discussed were transit times to Mars with the faster travel time mitigating some of the human factor challenges including nutritional issues. Also, it was clearly stated that to take on board the right type of nutrition, fresh items, seeds, perhaps small animals like chickens, a heavy lift launcher such as SLS was needed as the nutritional/food items will consume payload on the mission. Vadim said heavy lift was needed to carry out the mission in one launch given the need for substantive payload dedicated to food/nutrition & astronaut well being. Gender differences were discussed which is why Vadim suggested an all male first crew. Other questions were asked about artificial gravity, developing & using a nutritional pill for space missions, issues about why astronauts don't eat much on the ISS & more. Please post your comments/questions on The Space Show blog. You can email our guests through me.

About our guests...

Dr. Vadim Y. Rygalov
Vadim Y. Rygalov, Ph.D. in Physics & Mathematics, is a biophysicist and has worked in the area of Closed Ecological Systems (CES) studies and Bio-Regenerative Life Support since 1979 after his graduation with MS in Ecological Biophysics from Krasnoyarsk State University (KSU), Central Siberia, USSR. He is also an Associate Professor, UND John D. Odegard School of Aero-Space Sciences, Space Studies Department Consultant for KSC NASA Space Life Sciences Lab. During his education in KSU in 1969 – 1977 he was participating in a series of pilot researches related to investigation of human physiological and psychological limits. He received his Ph.D. for work ‘Systems Analysis of Environment/Organism Optimal Interaction: Sea Macro-Algae Growth and Development’ in 1987 from Institute of Biophysics, Siberian Branch of the Russian Academy of Sciences (Krasnoyarsk, USSR) and Pacific Research Institute of Oceanography & Fishery Sciences Ministry of Fishery Industry USSR (Vladivostok, USSR). His current interests involve studies of closed ecological system functioning and their applications for human life support in space; limits of stable human/environment interactions; human factor limits & control algorithms in high risk operations, etc. He is also interested in applications of developed technologies for human life support in unusual (primarily extreme) environments: years 1999 – 2004 he spent at the Space Life Sciences Lab KSC NASA working with Low Pressure Space Greenhouse prototypes.

Annie Wargetz
Annie Wargetz is a passionate space cadet who is currently a graduate student working towards a Master of Science in Space Studies at the University of North Dakota. She is focusing on the history, policy, psychology, and physiology of human spaceflight and will be defending her thesis in the spring on how to select and train a crew for a long-duration planetary mission. She is a research assistant in the Human Spaceflight Laboratory at UND and volunteers as the Fundraising and Outreach Coordinator for the UND Observatory. She also recently accepted the role of Advisor for the Astrosociology Research Institute and has joined the Outreach Committee at UND’s chapter of the American Meteorological Society. Annie has presented her poster on crew accommodations design for the Human Spaceflight Laboratory’s Planetary Exploration Initiative at several conferences, including the recent North Dakota EPSCoR conference. Annie gained more than eight years of experience in education/public speaking in the software industry before deciding to pursue her dreams of a career in space and its related industries. Prior to that, Annie graduated from the University of Houston with a Bachelor of Arts in Communication, where she focused on corporate communications, public relations, and advertising and minored in mathematics. Annie speaks English, French, and Spanish and hopes to someday soon be fluent in Russian, and also aspires to become the next “Carl Sagan” who gets the public excited about space once again. You can find Annie on Twitter as @SETIgal1124.This summer, Annie worked with Dr. Vadim Rygalov at the UND Department of Space Studies to research the effects of food and nutrition on human performance levels in extreme isolated and confined environments, the topic for which she is present on today’s show.
