amateur astronomy hobby in the east San Francisco Bay Area.
The Latest News & Upcoming Events
Lawrence Livermore National Laboratory built the gamma-ray spectrometer that flew on NASA's MESSENGER spacecraft to
the planet Mercury. We are presently building two new gamma-ray instruments to visit an exotic metal asteroid called
16-Psyche, and to visit the moons of Mars (Phobos and Deimos). Gamma-rays represent the highest-energy region of the
electromagnetic spectrum. They are scientifically useful because they help reveal the elemental composition of these
planetary bodies, which in turn helps us understand their formation and evolution. This talk will focus on the
technical challenges of building an instrument for deep space exploration, as well as the interesting science revealed
by gamma-ray spectroscopy at Mercury, 16-Psyche, and Phobos/Deimos.
Dr. Morgan Burks is a physicist specializing in instrumentation for high-resolution gamma-ray spectroscopy and
gamma-ray imaging. He has worked at Lawrence Livermore National Laboratory since 2002, and at Berkeley lab before
that. During this time he helped develop the first hand-held gamma-ray spectrometer based on germanium crystals, as
well as the first instrument that could take 360 degree gamma-ray images. Morgan helped build the gamma-ray
spectrometer that flew on NASA's MESSENGER mission to Mercury. That instrument took the first ever gamma-ray data of
the planet and the results have overturned our understanding of how Mercury formed. Morgan is currently the principal
investigator responsible for building instruments for a NASA mission to 16-Psyche and another to the Moons of Mars.
Dispose of your eclipse glasses!
Don't toss those eclipse glasses! Astronomers Without Borders has a
Eclipse Glasses Donation Program
to reuse eclipse glasses. TVS is registered as an eclipse glasses donation site, the only one in the Tri-Valley.
Bring your lightly used solar eclipse glasses to our general meeting, or mail them to our PO Box, P.O. Box
2476, Livermore, CA 94551 We will forward them to the AWB sponsor, Eclipse Scientific. They will be put to
better use than gathering dust in your attic!
