The city of Barstow and NASA’s Goldstone Visitor Center have a special speaker scheduled to make a presentation Monday night titled "Juno: Revealing Jupiter’s Interior."

Dr. Fran Bagenal will discuss Juno, NASA’s current mission in orbit at Jupiter, beginning at 6 p.m. in the Historic Harvey House, 681 N. First Ave., Barstow. There is no admission charge.

NASA’s Juno Mission began its orbit around Jupiter’s poles on July 14 as it carries instruments that probe Jupiter’s deep interior to measure the amount of water on the planet.

Bagenal will explain how water is an essential component of solar system evolution and reveal details on Jupiter’s aurora and more.

“They are making brand new discoveries, it’s breaking news,” NASA’s Goldstone Visitor Center Outreach Coordinator Leslie Cunkelman said. “They are just publicizing these new red spot findings.”

Bagenal recently retired as a professor of astrophysical and planetary sciences at the University of Colorado, however she has continued as a research scientist in CU’s labs. Bagenal has focused on NASA’s New Horizons Mission to Pluto and the Juno Mission to Jupiter for the past 15 years.

Before returning to the United States for research and faculty positions in Colorado, Bagenal spent five years as a postdoctoral researcher in England.

She has participated in a number of NASA’s planetary exploration missions, including Voyager 1 and 2, Galileo, Deep Space 1, New Horizons and Juno.

Bagenal’s expertise in the study of charged particles trapped in planetary magnetic fields correlated well with the Juno Mission as it was the first spacecraft to fly over Jupiter’s aurora, measuring the energetic particles raining down on the planet.

Although the presentation begins in the evening, the visitor center will open to the public at 10 a.m. Monday, including exhibit rooms with a number of NASA-related displays.

The all hands-on technology room for children features touch-screen pads that replicate the International Space Station along with earphones for listening to sounds of space and more. Each exhibit holds continuous video presentations as well, for additional information on the displays.

“This is geared for everybody but it is nice to have something extra for the children,” Cunkelman said. “We have a running loop of film. If they don’t want to hear us talk they can watch the TVs."

Bagenal’s presentation on "Juno: Revealing Jupiter’s Interior"will begin at 6 p.m. For more information, visit www.gdscc.nasa.gov.
