After nearly seven years of asking, "Are we there yet?" the Cassini-Huygens mission is poised to enter Saturn's orbit this evening.
Saturn is now a day away for the Cassini spacecraft, a seasoned traveler that began its journey nearly seven years ago.
On approach to Saturn, data obtained by the Cassini spacecraft are already posing a puzzling question: How long is the day on Saturn?
Irregular bright and dark regions of yet unidentified composition and character are becoming increasingly visible on Titan's surface as Cassini approaches.
Like a woolly mammoth trapped in Arctic ice, Saturn's small moon Phoebe may be a frozen artifact of a bygone era, some four billion years ago.
After completing a successful trajectory correction maneuver on Wednesday, the Cassini spacecraft is now on its final approach to Saturn.
Images from Cassini's flyby of Phoebe show evidence that the tiny object may contain ice-rich material, overlain with a thin layer of darker material.
First images from Cassini's flyby of Phoebe reveal it to be a scarred, cratered outpost with a very old surface.
With its flyby of Phoebe, the Cassini spacecraft has completed the first satellite flyby in its four-year tour of the Saturn system.
The most complex interplanetary mission ever launched is about to meet one of the solar system's enigmatic moons.
The international Cassini-Huygens mission is poised to begin an extensive tour of Saturn, its majestic rings and 31 known moons.
The Cassini spacecraft successfully performed a critical six-minute trajectory correction maneuver May 27 to put it on course with its first encounter, Saturn's outermost moon Phoebe, set for June 11.
NASA and European Space Agency officials will discuss the Cassini-Huygens Saturn mission next Thursday at 10 a.m. EDT.
Both Cassini and the Earth-orbiting Hubble Space Telescope snapped spectacular pictures of the planet and its magnificent rings.
The Cassini spacecraft caught two storms in the act of merging into one larger storm on the ringed planet.
The camera aboard the Cassini-Huygens spacecraft sent its best color postcard back to Earth of the ringed world.
