LLNL offers another exceptional season of Saturday science lectures

Lawrence Livermore National Laboratory's popular lecture series, "Science on Saturday," returns Feb. 4 and runs through March 3. This year's talks cover a wide range of current topics including the Lab's work on the Mercury Messenger; effects of earthquakes; space junk; and restoring sight to the blind.

The lectures are free of charge and will be held in the Bankhead Theater located at 2400 First St. in Livermore. Two presentations are offered at 9:30 a.m. and 11:15 a.m. This year the Lab is expanding the availability of the talks by streaming them live via the LLNL Facebook page .

"This is an excellent way to reach out to students no matter where they live," said Richard Farnsworth, manager of the Lab's Science Education Program.

Each lecture highlights cutting-edge Lawrence Livermore National Laboratory (LLNL) science presented by leading Lab researchers joined by master high school science teachers.

Kicking off the series of four Saturday sessions is: "The Gamma-Ray Spectrometer at Mercury: A Seven Year Journey to the Innermost Planet," by LLNL scientist Morgan Burks and teacher Dan Burns.

This lecture will discuss NASA's MESSENGER mission with a focus on the gamma-ray spectrometer and the importance of gamma-ray science in helping to understand the planet Mercury. This talk also discusses the science and engineering that allowed for the spectrometer to work at cryogenic temperatures in one of the hottest places in the solar system.
