卡罗琳·波尔科1953—

Carolyn C. Porco (born March 6, 1953) is an American planetary scientist who explores the outer Solar System, beginning with her imaging work on the Voyager missions to Jupiter, Saturn, Uranus and Neptune in the 1980s. She led the imaging science team on the Cassini mission in orbit around Saturn. She is an expert on planetary rings and the Saturnian moon, Enceladus.

She has co-authored more than 110 scientific papers on subjects ranging from the spectroscopy of Uranus and Neptune, the interstellar medium, the photometry of planetary rings, satellite/ring interactions, computer simulations of planetary rings, the thermal balance of Triton's polar caps, heat flow in the interior of Jupiter, and a suite of results on the atmosphere, satellites, and rings of Saturn from the Cassini imaging experiment. In 2013, Cassini data confirmed a 1993 prediction by Porco and Mark Marley that acoustic oscillations within the body of Saturn are responsible for creating particular features in the rings of Saturn.

Porco was founder of The Day the Earth Smiled. She was also responsible for the epitaph and proposal to honor the renowned planetary geologist Eugene Shoemaker by sending his cremains to the Moon aboard the Lunar Prospector spacecraft in 1998.

A frequent public speaker, Porco has given two popular lectures at TED as well as the opening speech for Pangea Day, a May 2008 global broadcast coordinated from six cities around the world, in which she described the cosmic context for human existence. Porco has also won a number of awards and honors for her contributions to science and the public sphere; for instance, in 2009, New Statesman named her as one of 'The 50 People Who Matter Today.'

In 2010, Porco was awarded the Carl Sagan Medal, presented by the American Astronomical Society for Excellence in the Communication of Science to the Public. In 2012, she was named one of the 25 most influential people in space by Time magazine.

Early life and education

Porco was born in New York City. She graduated in 1970 from Cardinal Spellman High School in the Bronx, New York City.

She earned a B.S. degree in Earth and Space Sciences from Stony Brook University in 1974. She received her Ph.D. degree in Planetary Sciences in 1983 from the California Institute of Technology in the Division of Geological and Planetary Sciences. Supervised by dynamicist Peter Goldreich, she wrote her doctoral dissertation focused on Voyager discoveries in the rings of Saturn.

Career

Voyager

In the fall of 1983, Porco joined the faculty of the Department of Planetary Sciences at the University of Arizona; the same year she was made a member of the Voyager Imaging Team. In the latter capacity, she was an active participant in the Voyager 2 encounters with Uranus in 1986 and Neptune in 1989, leading the Rings Working Group within the Voyager Imaging Team during the Neptune encounter.

Awards and honors

In 1999, Porco was selected by The Sunday Times (London) as one of 18 scientific leaders of the 21st century, and by Industry Week as one of 50 Stars to Watch. In 2008 she was chosen to be on Wired magazine's inaugural 'Smart List: 15 People the Next President Should Listen To.'

Her contributions to the exploration of the outer Solar System were recognized with the naming of Asteroid (7231) Porco which is "Named in honor of Carolyn C. Porco, a pioneer in the study of planetary ring systems...and a leader in spacecraft exploration of the outer solar system."

In 2008, Porco was awarded the Isaac Asimov Science Award by the American Humanist Association.

Musical interests

Porco is fascinated by the 1960s and The Beatles and has, at times, incorporated references to The Beatles and their music into her presentations, writings, and press releases. She visited 20 Forthlin Road, Liverpool, Paul McCartney's teenage home, after it opened as a Beatles Museum in 1995. The first color image released by Cassini to the public was an image of Jupiter, taken during Cassini's approach to the giant planet and released on October 9, 2000, to honor John Lennon's 60th birthday. In 2006, she produced and directed a brief 8-minute movie of 64 of Cassini's most spectacular images, put to the music of the Beatles, in honor of Paul McCartney's 64th birthday.
