A close look at Saturn's closest moons

Emily Lakdawalla • June 26, 2014 • 1

A new composite image of the eight named moons that orbit closest to Saturn, and a list of all the best Cassini observations of these moons.

Deep Impact's last images

Emily Lakdawalla • May 27, 2014

Today I received an email notification of new public releases of some image data sets. I always love seeing new public space image data, but this notification was bittersweet: it included the first public release of the very last image data returned to Earth by Deep Impact, of a distant comet ISON.

Dust on, dust off: Before-and-after comparisons of rover decks on Mars

Emily Lakdawalla • May 19, 2014 • 6

Curiosity and Opportunity self-portraits show one rover accumulating dust, the other losing it. Check out these cool before-and-after comparisons.

Image processing trick: Removing interline transfer smear from Curiosity photos

Emily Lakdawalla • May 01, 2014 • 2

Curiosity took a new self-portrait on sol 613. This post contains a tip for would-be Curiosity image processors on how to make their Curiosity mosaics better: removing the smearing effect of bright objects in MAHLI photos.

Another Pale Blue Dot — Uranus Spied By Cassini

Val Klavans and Ian Regan • April 30, 2014 • 1

The Cassini mission has already returned an array of images of other solar system members from Saturn orbit: Earth (and the Moon), Venus, Mars, and Jupiter. It’s time to add another world to that list!

Pretty picture: Sunset over Gale crater

Emily Lakdawalla • April 14, 2014 • 5

Imagine yourself on a windswept landscape of rocks and red dust with mountains all around you. The temperature -- never warm on this planet -- suddenly plunges, as the small Sun sets behind the western range of mountains.

Look how clean Opportunity is now!

Emily Lakdawalla • April 09, 2014 • 1

While climbing Murray Ridge, Opportunity enjoyed a major cleaning event that has left the rover's solar panels more dust-free than they have been in years. The rover captured a pretty panorama of the newly clean deck with its Pancams, and James Sorenson processed the version shown here.

A little fun with Cassini rings images

Emily Lakdawalla • February 25, 2014 • 7

It's happened again; I went into the Cassini image archive looking for something specific and wound up spending several hours playing with totally unrelated image data. Here are several beautiful images of the rings from the archives.

The Two Faces of Phoebe

Daniel Macháček • February 13, 2014 • 7

Cassini flew past Phoebe on June 11, 2004, on its way to entering Saturn orbit. The flyby was almost perfect but overexposure of some images have prevented color mosaics from being produced. Even though Phoebe's body is gray and dull in color, the absence of color images always provoked me. By using VIMS data, I have now produced color mosaics.

New Hills, Old Secrets

Bill Dunford • February 10, 2014 • 1

Exploring a set of newly named hills on Mars reveals tantalizing clues to the planet's story.
