This week we have Fred Calef III hosting astrotweeps. Fred graduated from the University of Alaska Fairbanks (UAF) in Geological Sciences in 2010. His dissertation was on fresh small rayed impact craters on Mars, looking at ejecta retention rates and what they tell us about the current environment and geomorphic evolution of the surface. He postdoc’d at California Institute of Technology (Caltech) via the Jet Propulsion Laboratory (JPL) doing landing site analysis for the Mars Science Laboratory (MSL, aka Curiosity) as well as trained as an Engineering Camera Payload Uplink Lead (ECAM-PUL) for the Mars Exploration Rover (MER) Opportunity. Towards the end of his postdoc, he was hired at JPL as the Geospatial Information Scientist, aka ‘Keeper of the Maps’, and Co-Localization Scientist for MSL. Besides work on MER and MSL, Fred is on the InSight lander science team as ‘Keeper of the Map’ for placement of a seismometer (SEIS) and heatprobe (HP3) as well as doing landing site analysis for InSight and the Mars2020 rover.

He works on topics involving thermal and collisional evolution of planetary bodies (comets, asteroids and terrestrial planets) and early compositional evolution in the solar system. Most of his research focuses on relating thermo-physical, chemical and dynamical properties of various small body populations to their origin conditions and evolution pathways. The ultimate goal is to understand how planetary systems arrange themselves and promote habitable conditions.
Emily Rice is an assistant professor in the Dept. of Engineering Science & Physics at the College of Staten Island (City University of New York), faculty in Physics at the CUNY Graduate Center, member of CUNY Astro, and resident research associate in the Dept. of Astrophysics at the American Museum of Natural History. She studies low mass stars, brown dwarfs, & exoplanets by studying their spectra and modeling their atmospheres. Additionally she is a co-author of a new lab manual for introductory college-level astronomy courses.
She frequently give public presentations, including at the Hayden Planetarium. Emily also makes fun videos, organize astronomy presentations at bars, and share science fashion. Some past projects include AMNH’s Science Bulletins and Cosmic Discoveries iPhone app.

Dr. Barbara Cohen leads the planetary science group at the Marshall Space Flight Center. Originally from upstate New York, Dr. Cohen earned her BS in Geology from the State University of New York at Stony Brook and her PhD in Planetary Science from the University of Arizona. She is now a planetary scientist at NASA’s Marshall Space Flight Center interested in geochronology and geochemistry of planetary samples from the Moon, Mars and asteroids.
Dr. Cohen serves within NASA representing science interests and capabilities within human spaceflight planning. She is a Principal Investigator on multiple NASA research projects, a member of the Mars Exploration Rover mission team still operating the Opportunity rover, and the principal investigator for Lunar Flashlight, a lunar cubesat mission that will be launched in 2018 as an SLS secondary payload. She is the PI for the MSFC Noble Gas Research Laboratory (MNGRL) and is developing a flight version of her noble-gas geochronology technique, the Potassium-Argon Laser Experiment (KArLE), for use on future planetary landers and rovers. She has participated in the Antarctic Search for Meteorites (ANSMET) over three seasons, where she helped recovered more than a thousand pristine samples for the US collection, and asteroid 6186 Barbcohen is named for her.
