  Preliminary Abstract:
     The Juno spacecraft entered into a polar orbit around Jupiter in July 2016 carrying JunoCam, a visible light camera. A new
understanding of Jupiter's clouds and storms is emerging from this unique perspective.

From Wikipedia:

"JunoCam (or JCM) is the visible-light camera/telescope of the Juno Jupiter orbiter, a NASA space probe launched to the planet Jupiter on 5 August 2011. It was built by Malin Space Science Systems. The telescope/camera has a field of view of 58 degrees with four filters (3 for visible light). The camera is run by the JunoCam Digital Electronics Assembly (JDEA) also made MSSS. It takes a swath of imaging as the spacecraft rotates; the camera is fixed to the spacecraft so as it rotates, it gets one sweep of observation.

JunoCam is not one of the probe's core scientific instruments; it was put on board primarily for public science and outreach, to increase public engagement, and all images will be available on NASA's website. It is capable of being used for science, and does have some coordinated activities in regards to this, as well as to engage amateur and as well as professional infrared astronomers."

Dr. Candice Hansen is interested in the seasonal behavior of volatiles not on Earth, atmospheres in vapor pressure equilibrium with surface ices (Triton, Pluto, KBO's), seasonal polar caps (Mars), erosional processes due to dry ice sublimation (Mars), outer planet satellites' tenuous atmospheres (Europa), and the plumes of Enceladus.

Dr. Hansen earned a Bachelor of Science in Physics from California State University, Fullerton, in 1976. The next year she began work at JPL, joining the Voyager Imaging Team as assistant experiment representative. Her task was to design the camera image acquisition sequences for every satellite flyby that occurred during Voyagers' encounters with Jupiter, Saturn, Uranus and Neptune. The Voyager encounters provided milestones marking many events in her life. From 1981 to 1984, the long cruise period between the Saturn and Uranus encounters, she worked at the German Space Operations Center in Oberpfaffenhofen. She worked on the Ion Release Module, the German portion of the Active Magnetospheric Particle Tracer Explorer, a multinational Earth orbiting mission designed to study the Earth's magnetosphere. After Voyager’s Uranus flyby she returned to graduate school at UCLA in 1987. In 1989, in the midst of preparing for the Neptune encounter, she finished her Master of Science in planetary physics and in 1994 completed her doctorate in Earth and Space Science, also at UCLA. Her dissertation included a thermal model of Triton's nitrogen frost and atmosphere, based on data acquired by Voyager during the 1989 Neptune encounter. She has also applied the thermal model to Pluto and other Kuiper Belt Objects. In 1990 Dr. Hansen began working on the Cassini mission to Saturn
with the Ultraviolet Imaging Spectrograph (UVIS) investigation team, responsible for planning and analyzing icy satellite data. She is still a UVIS
Co-Investigator as the Cassini project executes its extended mission phase. Her current research activity is studying Enceladus’ water vapor plume. Dr. Hansen
is also currently the Deputy Principal Investigator for the High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter. Her area
of interest is studying the seasonal CO2 polar cap of Mars.  She continues to pursue that interest as a Co-Investigator on the Colour and Surface Stereo and
Imaging System (CaSSIS) on the European Mars Trace Gas Orbiter in orbit at Mars. As a Co-Investigator on the Juno mission to Jupiter, that arrived at Jupiter
in 2016, Dr. Hansen is responsible for the development and operation of the JunoCam outreach camera that will engage the public in planning images of Jupiter.
Dr. Hansen retired from JPL in 2010 but continues in all her endeavors under the auspices of the Planetary Science Institute in Tucson. She was Chair of the
NASA Outer Planets Assessment Group from 2013 to 2016.

The Physics & Astronomy Department’s Bullitt Lecture is a free event aimed at the general
Since 2001, the Physics & Astronomy Department’s Bullitt Lecture has presented a
distinguished astrophysicist to a Louisville audience in the Gheens Science Hall and Rauch
Planetarium.  Gale Christianson, Hubble's biographer at Indiana State,
planetary expert Hal Weaver, stellar astrophysicists  James Kaler of U. Illinois,
C. R. O'Dell of Vanderbilt and Caty Pilachowski of Indiana U,  cosmologists Fang Li Zhi of Arizona,
J. Richard Gott of
Princeton, Alan  Dressler of the Carnegie Observatories and lunar experts
Ferenc Pavlics of GM and the Apollo project and Phillip Abel of NASA have been Bullitt Lecturers.

College and high school students, teachers, and many others from the community interested in
the impact and excitement that astrophysics has generated have attended Bullitt Lectures in
large numbers. The public and members of the University community are warmly invited!

The Lecture is endowed through a grant from the family of William Marshall Bullitt, the
Solicitor General of the United States under President William Howard Taft.  Here is
a brief biography and description of his connection to the University of Louisville.

Several of the 2006-2008 popular and Bullitt lectures are available in streaming (.asx) format in the
UL astronomy talk archive.
