About us…

The Mineralogical Society of Southern California is dedicated to the dissemination of a general knowledge of the mineralogical and related earth sciences through the study and collecting of mineral specimens. Organized in 1931, it is the oldest mineralogical society in the western United States.
The MSSC is a scientific non-profit organization that actively supports the Pasadena City College Geology Department,   Field Science Scholarship Fund.  Support is also given to Mindat.
The MSSC is affiliated with the California Federation of Mineralogical Societies and American Federation of Mineralogical Societies.

Program Notes: Join us Friday, October 8 at 7:30 PM for a presentation on Exploring Jezero Crater, Mars with the Perseverance RoverPresented by Dr. Sarah M. Milkovich

 For hundreds of years, the idea of an inhabited Mars has captured our imaginations, but our first close-up view of Mars showed it to be a cold, barren desert. For decades, NASA has been exploring Mars with a fleet of spacecraft to understand the role of water in its history and look for areas that in the past could have supported life. This work has paved the way for the Mars 2020 Perseverance Rover, which landed on Feb 18, 2021 in Jezero Crater with the ambitious mission to search for evidence of ancient bacterial life and to collect rock samples for eventual return to Earth. In the short time since landing, Perseverance has already been hard at work testing out its new capabilities and getting to know its new home.

Bio: Dr. Sarah M. Milkovich is a planetary geologist and systems engineer at NASA Jet Propulsion Laboratory, where she currently works on the Mars Perseverance Rover. Sarah specializes in the science operations of robotic spacecraft, bridging the science and engineering teams. In this capacity, she has spent over 15 years exploring Mars and Saturn with a variety of spacecraft. Sarah has won JPL and NASA team awards for her efforts to return the best possible science within spacecraft engineering constraints, as well as for excellence in outreach and public engagement. She holds a B.S. in planetary science from Caltech, and a M.Sc. and Ph.D. from Brown University in planetary geology with studies of ice on Mars, and volcanoes on Mercury.

***Participants who want to do this must respond to our Programs chair, Rudy Lopez at  no later than Tuesday October 5, 2021.  Please include “October  ZOOM Meeting” in the subject line of your response. This response date will allow time for us to send you the information needed to participate in the ZOOM meeting and also will allow time to get everything organized at Caltech.
