1. Monday, July 1, 2013, 2-3:30 PM PDT (21-22:30 GMT)
returns to discuss space radiation issues, especially issues relevant to recently announced HSF missions to Mars.
Dr. Marcelo Vazquez is an Associate Professor at the Radiation Medicine Department, Loma Linda University, CA.  Currently Dr. Vazquez directs several educational programs on radiation biology as well as develops translational research projects related to radiation therapy using protons.  He is also an independent consultant in space radiation, space radiobiology and radiation risks.



Dr. Vazquez worked for 11 years at the Brookhaven National Laboratory (BNL) supporting the NASA Space Radiation Health Program as a principal investigator, scientific liaison and program manager of the long-term support facility for NASA’s particle accelerator users.  Dr. Vazquez created, directed and managed the NASA Space Radiation Summer School at BNL from 2005 to 2006. After his work at BNL, Dr. Vazquez was hired by the National Space Biomedical Research Institute (NSBRI) at Baylor College of Medicine, to serve as the institute’ space radiation liaison to NASA as well as an advisor and senior scientist.  He also serve as a project manager for the NSBRI’ sponsored Lunar EVA Dosimetry project as well as the NSBRI’ Center for Acute Radiation Research.  Representing NSBRI, Dr. Vazquez was Field Research Participant at the NASA/Mars Institute/Haughton Mars Project station at Devon Island, Canada performing several experiments for NSBRI and NASA.  Scientific Interests: assess the effects of the space radiation environment on human health, develop medical countermeasures for deep space exploration, radiation oncology and first responders in case of a radiological accidents as well as the use of particle radiation to treat cancer.  Education and Concurrent Positions:  M.D. Nat’l Univ. of La Plata, Argentina, 1984; Ph.D. Nat’l Univ. of La Plata, 1990; Radiation Oncology Resident and Chief Resident, 1984-88; Doctoral Research Fellow, Radiobiology Department, National Commission of Atomic Energy, Argentina, 1986-90; Postdoctoral Research Fellow, School of Medicine, Uppsala University, Sweden.  Associate Research Scientist, Eye Rad. & Environ.

2. Tuesday, July 2, 2013, 7-8:30 PM PDT (July 3, 2-3:30 GMT)
of the BBC program, The Sky At Night. See http://www.bbc.co.uk/programmes/b006mk7h.
Dr. Paul Abel is a professional theoretical physicist at the University of Leicester- his work is in black holes and Hawking radiation. His first degree is in math, his PhD in theoretical physics. He has also been an amateur astronomer for many years, and has an observatory at my house where he does most of his lunar and planetary work.  He has known Sir Patrick Moore since the age of 12, and he got be started in astronomy.  He answered his letters and phone calls and helped me in my career as both an astronomer and as a science presenter.  I joined the Sky at Night in 2009 and I have been a co-presenter since then.  The Sky at Night continues to promote astronomy and space science to our diverse audiences.  Dr. Abel has written three books on astronomy.  His first ‘Visual Lunar and Planetary Astronomy’ by Springer is out at the end of July.  (http://www.waterstones.com/waterstonesweb/products/paul+abel/visual+planetary+astronomy/9634267/).  His  second book The Stargazer’s Notebook (http://www.waterstones.com/waterstonesweb/products/paul+abel/visual+planetary+astronomy/9634267/)  is due out end of November, and the third book he just finished &  is co-authored with Dr. Chris North from the Sky at Night  is called “How to Read the Solar System.”

3. Sunday, July 6, 2013, 12-1:30 PM PDT (19-20:30 GMT)
returns to discuss his work landing heavy payloads on Mars.
Dave Ketchledge who served as a submarine Nuclear Reactor Operator, a Control Systems Test Engineer for the Nimitz Class Carriers in digital instrumentation and as an instructor in core physics and material design. Dave has over 30 years in nuclear power field in Engineering.  His other works include a pair of books in Aerospace Engineering in Aerodynamics, Propulsion and RLV design. He has been a keynote speaker at the U of I  AIAA chapter.   For rocketry in 1993 he created the first Flight Dynamics software in Vertical Trajectory Systems which appeared in the Tripoli Journal in a 18 page article. Dave also contributed to the National Association of Rocketry on the design of multiplexed telemetry systems and in a report on Finite Element Mechanics for structural design. Dave holds two awards for his work with Computational Aerodynamics on Lifting Bodies from the NAR technical conferences.  As a Nuclear Systems Engineer he is involved in radiation monitoring systems and in core instrumentation for reactor safety.
