Remote laser-based spectroscopic techniques have made significant impacts on the future of planetary investigations. The ChemCam instrument on the NASA Curiosity rover has been exploring Mars since landing on August 5, 2012. The ChemCam instrument is the integration of a remote Laser-Induced Breakdown Spectrometer (LIBS) and a Remote Micro-Imager (RMI). The ChemCam LIBS instrument focuses a 1064 nm laser on rocks and soils up to 7 m from the rover mast. This focused laser ablates material from these targets generating a plasma containing electronically excited atoms, ions and small molecules. A telescope is used to collect some of the emission as these excited species relax to lower electronic states. The ChemCam laser has been fired over 600,000 time, each laser shot produces a quantifiable LIBS spectrum.
The Mars 2020 rover is currently under construction and will start to explore Jezero crater in February 2021. The Mars 2020 rover includes several instruments capable of microscale geologic analysis including SuperCam and Scanning Habitable Environments with Raman Luminescence for Organics and Chemicals (SHERLOC). SuperCam contains an integrated suite of remote LIBS, 532 nm (green) Raman Spectroscopy, Time-Resolved Luminescence Spectroscopy (TRLS), Visible and Infrared Spectroscopy (VISIR), color RMI, and a microphone. The SHERLOC instrument is an arm mounted ultraviolet Raman and Fluorescence Spectrometer designed to detect organic and biological materials in Jezero crater.
Finally, the Venus Elemental and Mineralogical Camera (VEMCam) is currently under development as a potential instrument for future explorations of the Venus surface. VEMCam is the integration of LIBS, 532 nm Raman Spectroscopy, Time-Resolved Luminescence Spectroscopy (TRLS), and color imagers. The Venus atmosphere at the surface consists of approximately 92 atm of supercritical CO 2 at approximately 740 K. Landers tend to survive in this atmosphere for only hours and rapid analyses are required. The VEMCam instrument is capable of recording more than 1000 LIBS, Raman, and TRLS spectra within the first hour on the surface from within the safety of the lander.
This presentation will focus on the ChemCam, SuperCam, SHERLOC, and VEMCam instrument physics. There will also be a discussion on the Curiosity and Mars 2020 mission goals and the contributions these instruments make to realize these goals.
Presented by Science at Cal & the Department of Art Practice
Worth Ryder Art Gallery 116 Kroeber Hall, UC Berkeley
Opening Reception: Wednesday, Feb 20 4 – 7pm
This acclaimed program returns for its sixth, and to date most varied and provocative exhibition of the convergence of science and art. Presenting artwork and installations across a range of media and technologies, Vision + Light: Processing Perception offers stunning visual, mind-bending virtual, and intriguing tactile experiences to spark thought and inspiration. Meet and share ideas with the scientists and artists whose work is on display. Join us for conversations on science, image, connections and creativity.
February 20 – March 14, 2019
Gallery Hours: Mondays – Thursdays, 12 – 5pm
Extended hours Tuesdays, 5 – 7pm
ACS @ Berkeley and Alpha Chi Sigma presents:
Speed networking and dinner with professionals in chemistry, biotech, chemical engineering, and more!

Question: Wouldn’t it be great if there was a “farmers market” style event where teachers could talk with people from a wide range of science education programs, for FREE, while noshing and networking with fellow teachers, all at an amazing science playground? Plus, prizes?!
Answer: We think so! And that’s why Community Resources for Science has teamed up with Chabot Space and Science Center to present our Spring Field Trip for Teacher event! Come join us on Saturday March 16th. You’ll receive free admission to the science center, delicious breakfast nibbles, and have the opportunity to peruse offerings from about two dozen science providers. Discover great science resources – from field trips, to in-class programs, to lesson plans, to professional development and more – all under one roof. Chabot will provide behind the scene access to their displays, classroom programs, field trip offerings, and more!
*Registration required: www.surveymonkey.com/r/ResourceFair2019 .
Even if you can’t attend, we would love to have you share out about this free teacher event with your teacher community.
