ABOUT THE SPEAKER
Carolyn Porco - Planetary scientist
As the leader of the Imaging Team on the Cassini mission to Saturn, Carolyn Porco interprets and shares the pictures coming back from this fascinating planet, its rings and its moons.

Why you should listen

Planetary scientist Carolyn Porco studies and interprets the photos from NASA space missions like the renowned Voyager mission to the outer solar system in the 1980s and the Cassini-Huygens mission to Saturn. She leads a team of scientists from the US and Europe that has been analyzing the images Cassini has sent back since it left Earth in 1997. At Saturn, they have found new phenomena everywhere they've turned their cameras … in the planet’s atmosphere, within its rings and on the surfaces of its many moons. And they've produced spectacular images and animations of these marvels in the process.

Back in the early-1980s, while still working on her doctorate, Porco was drafted onto the Voyager imaging team to assist in crunching the mountains of data coming back from Voyager’s fly-by of Saturn. Her work on the planet's rings and their relation to its moons cemented her connection with Saturn. After Voyager had flown by Neptune and was nearing conclusion, she worked together with Carl Sagan in planning Voyager’s celebrated Pale Blue Dot picture of Earth.

Her ongoing work at the Cassini Imaging Central Laboratory for Operations (CICLOPs) has two goals: to process, interpret and archive Cassini’s images for other scientists, and to make sure the images -- in all their breathtaking poetry and mystery and sheer Save-Image-As-Desktop awesomeness -- connect with the general public. She is an advocate for the exploration and understanding of planetary space, and her frequent talks (as well as her "Captain's Log" memos on the CICLOPS website) speak to everyone, scientist and nonscientist alike. Her advocacy extends to Hollywood, where she was the character consultant on the 1997 movie “Contact,” and a consultant on the 2009 Paramount Pictures re-boot of “Star Trek.” In 2012, she was named one the 25 most influential people in space by TIME magazine.

Finally, in a twist on the Pale Blue Dot theme, it was she who conceived the idea to invite the people of the world to smile while Cassini imaged the Earth on July 19, 2013 in an event called “The Day the Earth Smiled.”

ternyata lebih rumit dari laporan kami sebelumnya.
02:05
While they're not aminoamino acidsasam,
42
107000

Senyawa tersebut bukanlah asam amino,
02:07
we're now findingtemuan things like

whichyang is a discoverypenemuan that suggestsmenyarankan
49
123000
2000
Penemuan tersebut menyimpulkan bahwa
02:23
that not only do the jetsjet come from
50
125000
2000
semburan tidak hanya berupa air dari
02:25
pocketskantong of liquidcair waterair,
51
127000
2000

02:27
but that that liquidcair waterair is in contactkontak with rockbatu.
52
129000
3000
namun namun juga bercampur dengan batuan.
02:30
And that is a circumstancekeadaan
53

Dan keadaan tersebut
02:32
that could supplymenyediakan the chemicalbahan kimia energyenergi
54

02:34
and the chemicalbahan kimia compoundssenyawa neededdibutuhkan to sustainmenopang life.
55
136000
3000
dan senyawa kimia yang dibutuhkan bagi kehidupan
02:37
So we are very encouragedmendorong by these resultshasil.
56
139000
3000
Sehingga kami sangat termotivasi oleh hasilnya,
02:40
And we are much more confidentpercaya diri now than we were two yearstahun agolalu
57
142000
3000
dan sekarang lebih yakin dibandingkan dua tahun yang lalu
02:43
that we mightmungkin indeedmemang
58
145000
2000
bahwa kami mungkin
02:45
