土星光环:剧情介绍
Plot Summary:A mind-bending exploration of Saturn and its moons - and the possibility of life in the salt-water mists of one moon, Enceladus. Dr. Carolyn Porco leads NASA's digital imaging team on the Cassini mission, which has been exploring Saturn since 2004. Dr. Porco and her team have brought back breath-taking photographs, which transport us across Saturn's great luminous rings and onto the surface of its strange, extreme and wondrous moons.
