Saturn’s enigmatic moon Titan has turned out to be an unexpected treasure trove of Earth-like landscapes and bizarre weather systems – and there are even tantalising hints of a vast and warm underground sea sloshing inside.

Cassini Takes Close-Up of Enceladus Northern Hemisphere

Wednesday, December 22nd, 2010

NASA’s Cassini spacecraft will be making its close flyby of the northern hemisphere of Saturn’s moon Enceladus today, Monday, Dec. 20. The closest approach will take place at 5:08 PM PST (8:08 EST) on Dec. 20, or 1:08 AM UTC on Dec. 21.

NASA’s Cassini spacecraft successfully dipped near the surface of Saturn’s moon Enceladus on Nov. 30. Though Cassini’s closest approach took it to within about 48 kilometers (30 miles) of the moon’s northern hemisphere, the spacecraft also captured shadowy images of the tortured south polar terrain and the brilliant jets that spray out from it.

Status Update: Cassini to Resume Nominal Operations

Wednesday, November 10th, 2010

Engineers at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., expect the Cassini spacecraft will resume normal operations on Nov. 24. They have traced the steps taken by an onboard computer before Cassini put itself in precautionary “safe mode” last week.

Light zap in space hints at life origin

Thursday, October 28th, 2010

Scientists were tantalized when the Cassini spacecraft discovered molecules in the atmosphere of Saturn’s moon Titan that were too big for its onboard instruments to analyze.

The (Long) Weekend Warrior: Nine Moons, 62 Hours

Wednesday, October 20th, 2010

Taking a long-weekend road trip, NASA’s Cassini spacecraft successfully glided near nine Saturnian moons, sending back a stream of raw images as mementos of its adrenaline-fueled expedition. The spacecraft sent back particularly intriguing images of the moons Dione and Rhea.

New Views of Saturn’s Aurora, Captured by Cassini

Saturn’s moons team up

Sunday, September 12th, 2010

Saturn’s 62 moons range from overgrown rocks that are less than a half-mile wide to giant Titan, which is bigger than the planet Mercury. These pictures from the Cassini orbiter show off two “quartets” of moons against the backdrop of Saturn’s rings.

Cassini Captures a Divine Dione

Thursday, September 9th, 2010

Saturn floats on gossamer rings

Wednesday, September 1st, 2010

It’s been a year since Saturn’s equinox, but the pictures from that magical moment are still being processed and shared by the imaging team for the Cassini spacecraft. The latest image, based on data acquired in July 2009 from a distance of 1.3 million miles, shows the shadows from Saturn’s gossamer rings falling on the planet’s disk as a single narrow band.
