tolga_photoTolga Guver

Tolga Guver is a post-doctoral associate at the University of Arizona, Department of Astronomy. He has finished his PhD in Istanbul University in 2008.

In the present he is working on high-energy astrophysical phenomena related to compact objects, black-holes, white dwarfs and neutron stars, he is especially using X-ray observations of these sources, obtained by Chandra and

XMM-Newton observatories. Guver is mainly concentrated on magnetars, neutron stars with very strong magnetic fields (10^{14-15} Gauss). His focus has been on the development of detailed models of phenomena that take place in the vicinity of magnetars and the application of these models to the spectral and timing properties of anomalous X-ray pulsars and soft- gamma repeaters.

As the most compact known objects without event horizons, neutron stars also offer a unique and extraordinary laboratory to study the equation of state of ultra-dense nuclear matter.  Tolga Guver recently undertaken a project to measure the masses and radii of the neutron stars in X-ray binaries. Using these mass-radius measurements it will be possible to define the equation of state of ultra-dense matter in the cores of neutron stars.


jenkins_jon_3_enh11 Jon Jenkins

Co-Investigator for the Kepler mission, SETI Institute

Jenkins, along with his team, many of whom are amateur astronomers themselves, “are the “dream team” of data analysis. This team is well aware that some of the calibrations and data processing algorithms may have to be altered as the mission progresses.

Jenkins recognizes that he is very dedicated to the Kepler mission. “In almost everything I do, I am very focused – somewhat obsessive. The fun for me in doing something is doing it well – taking my ideas, implementing them and improving upon them.” Jenkins understands this urge to work on something and make it perfect. Jenkins was part of the original proposal team for Kepler, and has been helping to make this mission perfect for the past 14 years.” From NASA’s website.

NickNicholas Previsich

A retired US Air Force avionics technician, Nick Previsich has had a lifelong fascination with spaceflight and the exploration of the Solar System. His earliest memories include waking up specifically to watch Gemini launches, and struggling to stay awake at the age of six to watch Neil Armstrong set foot on the Moon.

The tangible reality of the relationship between the larger Universe and the Earth was driven home to him on Aug 10, 1972, when he witnessed–and heard– the famous daylight fireball over western Montana. Another memorable experience occurred during the total solar eclipse of Feb 26, 1979, when by good fortune he encountered a group of JPL scientists who told him that Jupiter’s moon Io was looking “interesting” in far encounter images from Voyager 1; a week later, the world found out just how interesting Io really was!

Due to these and many other experiences, he is convinced of the overwhelming importance of spaceflight for both the present and future of humanity. Toward that end, he was honored when Rui Borges asked him to contribute his perspective to Beyond The Cradle in order to promote interest in what is arguably Man’s greatest and most crucial endeavor.

A frequent poster on the respected forum, Previsich lives in Los Angeles and works in the aerospace industry.


ppsDr. Paul Schenk, currently a staff (not staph) scientist at the Lunar and Planetary Institute in Houston Texas, is also a deep sea diver, scuba diver, traveler, mapper, and occasional dabbler in amateur stained glass.  Rejected from art school, he was lucky to discover the fascinating world of geology just as the Voyager spacecraft to the outer planets were on their way to the Outer Solar System.  He applied for and was awarded a NASA summer internship at JPL to witness first-hand the Voyager 2 encounter with Jupiter in 1979, including the first high-resolution images of Europa.  He did not quite suspect that decades later he would be making high resolution topographic maps and movies of the surface of this strange water world.  His parallel interest in antique deep sea diving with helmet and lead-soled boots does not make him an expert in extreme environment survival but he likes to think it qualifies him for future Europa exploration, despite the need for a 15 kilometer long airhose to get him beneath the outer ice layer.

Paul has been mapping the icy satellites of the outer planets since graduate school days at Washington University in Saint Louis and is currently assisting the New Horizons team plan Pluto encounter observations for July 2015.  He specializes in impact craters and their effects on icy satellites, and in 3-D imaging of their surfaces, which he uses to measure topography and create really amazing stereo views.  Over the years he has discovered plate tectonics on Europa, the highest mountains on Io (17 kilometers!), the compressional origin of Io’s mountains, diapirism on Triton, the impact of tidally disrupted comets onto the Galilean satellites, the thickness of Europa’s ice shell (roughly 15 to 20 kilometers), and polar wander of Europa’s ice shell, among other things.  Today he is working frantically to finish his new book, an Atlas of the Galilean Satellites highlighting the Voyager and Galileo missions to Jupiter, due out this fall.  He has received no major awards, for which he is grateful for not having to have given a long speech.

ps_01Phil Stooke is a planetary cartographer at the University of Western Ontario in London, Ontario, Canada. He works in the Department of Geography and is also affiliated with the Department of Physics and Astronomy and the Centre for Planetary Science and Exploration. His Ph. D. research at the University of Victoria involved mapping asteroids, work which included designing map projections and shape modelling methods for irregularly shaped small bodies. More recently he has worked on locating spacecraft on the Moon and Mars, and has compiled a historical atlas, The International Atlas of Lunar Exploration. This book uses maps and images to provide a uniquely detailed history of the exploration of the Moon.
He is now working on a similar atlas of Mars exploration.



Dr. Alexander Zaitsev is a Chief Scientist of the Radio Engineering and Electronics Institute, Russian Academy of Science. His career has been marked by three major areas of interest: First, radar devices used in the study of Venus, Mars, and Mercury, particularly direct digital synthesizers of coherent radar signals (the subject of his M.S. thesis, 1981). Second, near-Earth asteroid radar research (the subject of his Ph.D.dissertation, 1997). Dr. Professor Zaitsev has been able to successfully conduct international radar astronomy research projects with Europe, the United States and Japan. In 1992, he led a team of radar astronomers who successfully tracked the asteroid 4179 Toutatis to a distance of 3.6 million kilometers from Earth. This was the first non-U.S. asteroid radar experiment. Third – interstellar radio messaging (at present). He supervised the transmission of the 1999 and 2003 Cosmic Calls from Ukraine. In addition, under his leadership, a youth group in Moscow composed and broadcast a very moving Teen Age Message to ETI, including a beautiful “Theremin Concert for Aliens.” A pioneer in active SETI, he coined the acronym METI (Messaging to Extra-Terrestrial Intelligence), and dialogs extensively with both proponents and critics of this admittedly controversial activity. In 1985, Zaitsev received the Soviet Governmental Prize in Science. In 1980 he received the Koroliov Gold Medal of the Soviet Space Federation. In 1994 he received the Tsiolkovski Gold Medal of the Russian Space Federation. In 1995 the International Astronomical Union named the asteroid number 6075 as “Zajtsev.”
