We welcomed Dr. Bill Rowe back to the program to discuss cardiovascular issues for human spaceflight & EVAs, plus many other issues pertaining to long duration spaceflight. Note that we experienced serious phone line issues with Bill about 12 minutes into the program forcing us to stop for repairs. Evidently the fiber phone lines now serving Dr. Rowe cause broadcast equipment problems. Bill was able to go to a neighbor’s house to do the show but you will hear some line issues plus unusual cuts as I spliced together part of his opening to the point we were able to resume with a good phone line. Once past that point, there were no further phone line issues. During the first segment of our 2 hour 11 minute program, Dr. Rowe introduced us to his discussion main points and we began using his website for references throughout the show. It is important to be on his website and go where he points at various times in the discussion (see http://www.femsinspace.com). While parts of the discussion relied on medical terms and descriptions, our guest did an excellent job of breaking it down for us non-medical types to easily understand the information he was sharing with us. Among the issues we talked about were cardiac issues that don’t present symptoms, plus the problems with increased adrenalin secretion in the body which happens in space. Dr. Rowe spent significant time discussing the adrenalin issues citing known astronaut examples. In fact when talking about the adrenalin levels in space, he said that within five days of being in space the levels are twice that of being on Earth. Another issue brought up was possible cardiovascular damage for excessive exercise and here he cited the research projects he had been involved in with marathon running athletes. He strongly suggested the use of regularly taken electrocardiograms on the crews while in space. Next, Dr. Rowe talked about EVA issues, specifically cooling. He explained other risks and made the case for future robotic EVA missions instead of human mission. Before the segment ended, he had much to say about exercise in space.
In our second segment, Bill reviewed for us his comments on oxidative stress and suggested we follow along with his website submarine model, http://www.femsinspace.com/Oxidative_stress.htm. A listener then emailed in that the ISS did have an ultrasound on board which could be used for the purposes Dr. Rowe suggested (see http://www.nasa.gov/mission_pages/station/research/benefits/ultrasound.html). Bill talked more about lunar dust toxicity plus magnesium and calcium usage in space and in general. He referenced former astronaut Jim Irwin losing consciousness for a brief time on the Moon & he provided the reference for that fact. Rodent research on the ISS was discussed, then he got a listener question about possible different health standards for government trained and fit astronauts as compared to space tourists and possible private sector astronauts. Near the end of our discussion, space tourism came up and he pointed out risks for the middle age, overweight segment of the space tourism market. Bill spoke to pharmaceutical use in space and the issues with it. Just before ending our discussion, he pointed out that for Mars he thought an all female crew was best given the advantages they have over men. He did explain his comment.

We welcomed Dr. Rowe back to the program to discuss his latest findings regarding four Apollo astronauts, lunar dust, microgravity, and cardiac conditions. His work is presented on his website so do check it out, www.femsinspace.com. Dr. Rowe’s latest findings came from his research using the Freedom of Information Act to get medical data from NASA after the recent passing of Neil Armstrong. During our first segment, Bill explained what he found, what specific blood pressure and other information strongly suggests, and his comparison of the Armstrong data with that of several other Apollo astronauts per available data. He also brought our attention to the problem independent researchers have in getting Apollo information and medical stats from NASA. Bill used stress test blood pressure numbers and other medical information from the astronauts in question to illustrate his points and to back up his conclusions. Most of our first segment was devoted to Dr. Rowe putting forth the information and his conclusions. Bill took several email questions and listener calls, often wanting more information than he could provide because the reality is that there is an absence of additional information or relevant studies suggested. One listener was asked if the ISS astronauts evidenced similar cardiac problems. Dr. Rowe was unable to answer that question due to the absence of information.
In the second segment of this 2 hour 20 minute program, Dr. Rowe connected problems of lunar dust with urban pollution, suggesting microgravity studies that would benefit millions on Earth given how widespread the problem of urban pollution is on the planet. One of the studies he proposed would use 30 female rats subjects to different calcium/magnesium rations on the ISS for six months. Bill spent time in this segment explaining the importance of the calcium/magnesium ratio and what this means in space and for us back here on Earth, hence the rat study. Dr. Rowe also talked about the difficulty of having a quality exercise RX for microgravity. A listener asked about studies related to the Mt. St. Helens eruption several years ago re dust exposure. Near the end of our discussion, Bill talked about their being no hurry to go to Mars, suggested many of the near term human spaceflight missions such as one way trips to Mars won’t happen for a long time because the human issues will not be resolved in the near term. He also advocated the Moon first. We talked about artificial gravity and I mentioned what other human factor gusts have said on air in that artificial gravity may not be the same as 1g here on Earth and may prove to not be a solution. Listeners did not like hearing that as they kept saying there would be an engineering solution to the microgravity issues. Listener disagreements about artificial gravity not being the same as earth gravity continued long after the program ended.
