Gregory T. Shanos, PharmD, is a pharmacist by profession and NASA Solar System Ambassador by passion. Greg is an avid amateur astronomer and member of the St. Petersburg Astronomy Club (SPAC) Local Group of Deep Sky Observers (LGDSO) and Museum Astronomical Resource Society (MARS) in Florida. Greg’s interest in astronomy began in 1985 with the apparition of Halley’s Comet. His passion for meteorites began a year later when Sky & Telescope advertised authentic meteorites for sale. After purchasing three iron meteorites for a total of $60, he was hooked for life! Dr. Shanos has also published over 30 review articles in Meteorite magazine regarding organic compounds in meteorites. Greg has lectured extensively on various astronomical topics and has submitted observational data on meteors, comets and grazing occultations that have been published by the International Meteor Association, International Occultation Timing Association and Smithsonian Astrophysical Observatory. He has also participated in distributive computing projects such as SETI@home and Stardust@home. An avid eclipse chaser, Greg has witnessed thirteen total solar eclipses, three annular and the entire transits of Venus from Greece and Hawaii. Recent advances in digital technology have led Dr. Shanos into planetary and deep sky astrophotography. Other hobbies include playing folk and pop classics on my Guild D55 acoustic guitar. In addition, Greg has been studying the martial arts and earned his blackbelt in Mi Zong Long Horn, a Northern Shaolin Kung Fu System in 2007. Currently Greg is studying Chen Style Tai Chi and Yoga.
