Introducing Fred Calef III

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.
