luther beegleDr. Luther Beegle

Dr. Luther Beegle is the group supervisor for the Planetary Chemistry and Astrobiology Group. He is an experimental astrophysicist by training and is currently researching the potential distribution of life in the solar system including methodologies for identifying biosignatures. Dr. Beegle has extensive experience developing and designing instrumentation such as organic molecule extract techniques, charged particle optics, ion mobility spectrometers, and cylindrical ion trap mass spectrometers for space and terrestrial applications. Part of his astrobiology related interest is how robotic sample acquisition techniques physically and chemically alter the components of samples on current and future in situ missions. Dr. Beegle is currently a Surface Sampling Scientist on the Mars Science Laboratory where they work with the science team to identify suitable high valued scientific samples that will not damage the Sample Acquisition, Sample Processing and Handling (SA/SPAaH) on the MSL rover.

Description: Jennifer BlankDr. Jennifer Blank

Jennifer is a geochemist who likes to study life that walks on the wild side. Testing the extremes of biochemistry is more than just setting records, however. Since most of the worlds beyond Earth sport conditions that are far less friendly than those of our own, it may be that the vast majority of all life is, in fact, of the extreme variety. By heating and squeezing molecules in fluids, Jennifer has learned that some fluid-based organic molecules that would simply disintegrate when heated in a laboratory beaker maintain their structure when the fluid is under pressure. This could clearly be an encouraging finding for those who hope to find, for example, life near a hot vent at the bottom of a deep, alien ocean.

She’s also learned that if you apply sudden pressure (and concomitant heat) to organic molecules, some will survive, and others will often reassemble, or polymerize, into yet more interesting biologically relevant compounds. Imagine amino acids formed in the icy interior of a comet that later smashes into a planet. Some of the amino acids will survive the impact, and others will polymerize into peptides, which is also a biologically important compound. It seems that life’s precursors don’t mind getting smashed.

Description: r bonacorsiDr. Rosalba Bonaccorsi

Dr. Rosalba Bonaccorsi is an interdisciplinary scientist working at NASA Ames Research Center. In 2001 she obtained her Ph.D. in Geological, Marine and Environmental Sciences from the University of Trieste (Italy). Since 2005 she has expanded her interest to the habitability of mineralogical Mars analogs, and very dry desert regions worldwide, including the Mojave, Antarctica, Atacama (Chile), and Australia, often as a NASA Spaceward Bound team member. Rosalba joined the SETI Institute in 2008, and is keen to achieve a wide picture of where life and its signatures are most successfully distributed, concentrated, preserved, and detected. Since 2008, Rosalba has been working in Death Valley on the Ubehebe Volcanic Field. In 2012 Rosalba joined the Volunteer Program as Field Researcher in support of the Resources Management’s conservation effort in Death Valley Natl. Park. In collaboration with NASA scientists, she is applying results from this research to Mars Science Laboratory mission objectives. Formerly a teacher, she has been involved with Education and Public Outreach with non-profit organizations since 1989.

Teresa Jiles

Teresa is a Research Associate with Colorado State University's Cooperative Institute for the Research In the Atmosphere (CIRA). Her primary duties with the Night Skies team are night sky quality assessment fieldwork, park lighting projects, education outreach, and volunteer coordination. Teresa has a B.S. in Geology from Arizona State University with additional studies in astronomy and planetary sciences, as well as graduate research work in astrobiology. Prior to the joining the Night Skies team, Teresa's professional experience included working in research teams at NASA Johnson Space Center and The University of Arizona Steward Observatory. Teresa often spends June of each year, for the past 15 years, at The University of Arizona Alumni Association's Astronomy Teen Camps as a senior counselor. Her passion for astronomy education drives her commitment to share and preserve dark night skies for future generations. Teresa will never forget her first trip to Grand Canyon National Park as a freshman on a geology field trip. Standing on the edge of the south rim on a dark night, she witnessed a faint light beautifully reflecting off the light-colored rocks on the canyon walls. To her surprise the light was coming from the planet Venus. As she stood astonished, she recalled the Greek tale of Venus, the goddess of beauty and love, watching it shine so brilliantly high in the sky, she finally understood why they believed this "little wanderer" was the goddess of true beauty.

kirschvinkDr. Joseph Kirschvink

Joe was born and raised in the Southwest United States, which does not necessarily explain his infatuation with geology and biology, but it helps. Rather than attending an undergraduate university on the East Coast, where all of the rocks are covered with green goo, Joe chose to pursue his undergraduate education in Pasadena, California, where the atmosphere itself in the early 1970s was capable of cleaning the rock surfaces to show the beautiful geology underneath. However, upon the advice of two mentors (one with his magnetic mind in the stars, and the other more mindful of the magnetic minerals made by microbes), he reluctantly agreed to serve time in the East among the Ivy leaves at Princeton for his Ph.D. Joe did this, however, by traveling through Australia for a year (he recently went back, and is shown here standing on the Hamersly banded iron formation), and by spending about 50% of this time as a graduate student somewhere "in the field". He abandoned his experiment with the East Coast in 1981, and has been on the faculty back at Caltech ever since.

Joe has a lot of fun creating "nutty" ideas like the snowball Earth, and confusing paleontologists by trying to convince them that the Cambrian explosion was caused by a series of interchange events in the orthonormal Eigenvectors of Earth's Moment of Inertia Tensor. (A good number of paleontologists actually know what a tensor is, and realize that a moment of inertia is not just what keeps them in bed in the morning.) Joe even pretends that animals can predict earthquakes, just to keep his seismological colleagues on their toes. His major claim to being a paleontologist is his prediction and discovery of magnetofossils, which are not very useful for biostratigraphy but are wonderful as a Martian biomarker and for increasing the NASA Astrobiology budget.

Joe likes to swim and ski, and to explore the hot mineral waters produced by Mother Earth. He is married to a neurobiological electron microscopist, Atsuko Kobayashi, and they have two children (Jiseki and Koseki), whose names mean "magnetite" and "gemstone" respectively in Japanese. As a result, the children will probably grow up to be bloodsucking lawyers. And his family still doesn't know if home is in Pasadena or Osaka.
