The Space Show, hosted by David Livingston under www.TheSpaceShow.com, will have the following guests this week:

1. Monday, October 18, 2010, 2-3:30 PM PDT (21-22:30 GMT)
Dr. Chris Koehler
, Chair of National Council of Space Grant Directors & Director of Colorado Space Grant with students Shawn Carroll and Emily Logan.

Chris Koehler
strongly believes in providing students with meaningful hands-on experiences centered on small satellites. He is the Director of NASA’s Colorado Space Grant Consortium, which is headquartered at the University of Colorado at Boulder. He is also the Chair of the National Council of Space Grant Directors. Mr. Koehler earned a BS in Aerospace engineering and a MS in Mechanical engineering from the University of Colorado at Boulder in 1992 and 1994. As a student, he and a team of students launched two Shuttle GAS can payloads in 1992 and 1993, two sounding rockets, and one hitchhiker experiment through the Colorado Space Grant program. After graduation, he worked at Lockheed Martin Astronautics in Denver designing propulsion and antenna systems for large satellites for six years as a senior engineer.



During his time at Lockheed Martin, he led over 75 high school students through a 40 week intensive hands-on Engineering Explorers program for 10 years. It was this interaction with students the made Mr. Koehler realize that what he really enjoyed was teaching and mentoring students. In May 2000 he re-joined NASA’s Colorado Space Grant Consortium as the Student Research Coordinator to spend the next portion of his career ensuring students continue to receive hands-on experiences with space. He became the director of the statewide program in November 2005. He began the BalloonSat program in 2000 which has given over 7,500 Colorado students these types of experiences and he has helped start 100 ballooning programs around the country. He created a new hands-on and multidisciplinary course for engineering and science students at the University of Colorado at Boulder. This course is one of the more popular courses in the college because student teams design, build, test, and launch a real working satellite in one semester. This course is now being taught throughout the country. He has lead the statewide program called DemoSat in which students from 11 Colorado colleges and universities work with engineers and scientists from NASA’s Jet Propulsion Laboratory to demonstrate ideas and technologies on high altitude BalloonSats. Students present their results from their missions at JPL each summer. Several students have gone on to work at JPL and other NASA centers. This program is currently in its eighth year. Chris has also led several national hands-on workshops that teach students and faculty how to build both BalloonSats and sounding rocket payloads. These workshops have helped create numerous new programs around the country for college students. Chris continues to work to add new and more challenging hands-on programs for students of the Colorado Space Grant Consortium so that current and future students can graduate with experiences they need to continue the exploration and understanding of space. Chris has managed over 130 student space projects and has mentored and taught over 1,500 hundred students.

Shawn Carroll is a graduate student at the University of Colorado at Boulder in Aerospace Engineering Sciences. Shawn grew up in Longmont, Colorado and has always had a passion for space and building things. Not sure exactly what he wanted to do with life, although it should have been obvious, Shawn completed two years of school at a community college in general education classes. In 2006 Shawn transferred to CU and began pursuing his education in aerospace engineering. During his first semester at CU, Shawn was enrolled in Chris Koehler’s Gateway to Space class, which introduced him to high altitude balloon payloads and the Colorado Space Grant Consortium. In the spring, Shawn took leadership of a high altitude balloon payload testing hardware for Space Grant’s CubeSat, Hermes. The program was rather successful, and Shawn moved on to manage a sounding rocket program at Space Grant. After one semester as the Project Manager of RocketSat, Shawn was offered the unique position to orchestrate and manage COSGC’s first hands-on sounding rocket workshop, RockOn. The first year was a phenomenal success and lead to the development of the RockSat-C program to offer students low-cost access to space via sounding rockets at Wallops Flight Facility. Under Shawn’s management in 2009 and 2010, the RockOn and RockSat-C program continued to flourish, and Shawn is currently managing COSGCs newest endeavor to put student hardware in space, RockSat-X.

Emily Logan is a junior majoring in Aerospace Engineering and minoring in Electrical Engineering at the University of Colorado at Boulder. I have four siblings and grew up in Colorado. Math has always been my favorite subject, followed closely by science. The Harry Potter series is my absolute favorite book, but science fiction books such as Ender’s Game are also fun to read multiple times. I also really enjoy watching movies. Until senior year of high school I was unsure what I wanted to do in college, but one day I was asked what I wanted to be (for the yearbook) and at that moment I realized I wanted to go to space as an astronaut and explore the completely new environment, or hopefully by the time I graduate, a whole other world. This newfound desire to be an astronaut led me to choose to study Aerospace Engineering.
At CU, I took the Gateway to Space class, which allowed students to send their own mini-payloads up to 30 km (or “near space”). The experience of designing, building, and finally watching our project soar away on the balloon really sealed the deal that this was what I wanted to do. After that class I got involved as a Mission Specialist on the RocketSat team. I worked on the summer team and help prepare the payload for launch in Virginia. I attended the launch, and this inspired me to come back to the project as the project manager. The next year I managed the entire team for the launch this past June, which was yet another incredible experience. Managing this project also solidified my desire to continue my work with the EE minor because the payload electronics were extremely temperamental. I really like the idea of the RockSat program providing launch opportunities to students because I had benefited so much from them, so I then took over the RockSat-C program to continue to lead and encourage students to use what they learn in class to build actual payloads to go to space!

2. Tuesday, October 19, 2010, 7-8:30 PM PDT (October 20, 2-3:30 GMT)
Dr. Robert Fitts
, Professor and Chair of the Department of Biological Sciences, Marquette University. Dr. Fitts will be discussing his latest study in conjunction with NASA regarding muscle deterioration and atrophy with astronauts.
Dr. Robert Fitts earned his B.S. in 1967 from the State University of New York-Cortland, his M.A.in 1969 from the University of Buffalo, and his Ph.D. in 1972 from the University of Wisconsin in Madison. He did Postdoctoral Fellow studies at Washington University. His laboratory’s primary goal is to understand how muscles generate force and elucidate what processes control excitation and contraction (E-C) coupling. In addition to these basic questions, we are evaluating how weightlessness (and models of weightlessness) and fatigue alter muscle function. Finally, we are interested in the effects of regular exercise-training with particular emphasis on its role in preventing the deleterious effects of zero-g and fatigue on skeletal muscle function. We have recently begun to study the role of regular exercise in improving the functional capacity of the whole heart and isolated single myocytes.
Our research effort is directed primarily on three projects: (1) the etiology of muscle fatigue, and (2) the role of high resistance and endurance exercise in improving heart cell function, and (3) the effect of microgravity on the structure-function relationship in skeletal muscle. Currently, we are evaluating the effects of long-term flight aboard the International Space Station. Our goal is to determine the time course of the deleterious alterations in muscle with microgravity so that we can model the expected changes that would occur on a very long duration flight such as a trip to Mars. Related projects are studying the causes of the increased susceptibility to muscle damage (and resulting muscle soreness) that is experienced by all crew members post-flight, and work designed to assess the effectiveness of current exercise countermeasures. Our fatigue studies have centered on 2 processes: 1) the role of excitation-contraction coupling (ECC) in muscle fatigue; and 2) the effect of inorganic phosphate (Pi) and H+ on the force and power production of isolated single fibers. The ECC studies utilize voltage clamped rat fibers to elucidate the cellular causes of a particular type of fatigue know as low frequency fatigue (where force is lost selectively at low frequencies). Preliminary data suggests the main problem involves a disruption of the SR Ca2+ release channel. Our studies on the role of Pi and H+ in muscle fatigue have concentrated on the role of these ions in directly inhibiting the force production of the contracting fiber. Details of our Pi and H+ experiments can be found in a recent publication
