Some lovely, rarely-seen images from the MESSENGER mission.

The First Taste of Mars

Bill Dunford • March 11, 2013

Nearly four decades before Curiosity, we dug into Mars for the first time. The pictures are still amazing.

The Stormscapes of Saturn

Bill Dunford • March 04, 2013

Look past the rings, and Saturn is even stranger--and more breathtaking.

Galileo's images of Gaspra

Emily Lakdawalla • March 01, 2013

Last week I trawled the archives to find all of Galileo's images of asteroid Ida; this week, I turned to Gaspra.

Presenting a newly-processed version of Voyager 2's best images of Uranus' moon Umbriel.

Postcards from Clementine

Bill Dunford • February 25, 2013

Nineteen years ago this month, the Clementine mission sent some amazing views from the moon.

Galileo got so many more images of Ida than I realized

Emily Lakdawalla • February 22, 2013

While writing up the cruise-phase issues of the Galileo Messenger a couple of weeks ago, I came across a fuzzy montage of images of Ida that I had not seen before. So I decided to spend some time digging into the Planetary Data System to see if there were more images to be found. I found lots and lots pictures that I'd never seen before!

Arc of Ice and Light

Bill Dunford • February 18, 2013

When the sunlight catches it just right, Saturn's F Ring is something to see.

An evening that brought me very close to Curiosity

Damia Bouic • February 15, 2013

Damien Bouic received some well-deserved recognition from the Chemcam team for his great Curiosity image processing work.

The Earth is a Planet: Why We Explore Space

Bill Dunford • February 11, 2013

Why spend effort and scarce resources on space exploration when we have so many problems here at home? Turns out, there are some pretty good reasons.

Browsing Landsat data is a lot easier than I thought it was

Emily Lakdawalla • February 08, 2013

With the Landsat Data Continuity Mission scheduled to launch on Monday, there's been a lot of Tweeting about Landsat, and through one such Tweet I learned about a resource that I hadn't known existed before: the LandsatLook Viewer. This is a graphical interface to more than a decade worth of Landsat data, a tremendous resource for anyone interested in Earth's changing surface, natural or manmade.

Pretty picture: tessera terrain on Venus

Emily Lakdawalla • February 07, 2013

In which I dive into the Magellan radar data set and come up with some images of an unusual and possibly unique solar system terrain: tessera.

A new rover self-portrait and a new color image of Curiosity from orbit

Emily Lakdawalla • February 04, 2013

Curiosity is inching her way through her first use of the drill on a Martian rock. She paused in the proceedings to capture a second Martian "selfie."

Day Hikes in the Labyrinth of Night

Bill Dunford • February 04, 2013

Noctis Labyrinthus on Mars is an amazing place for an imagined day hike, courtesy of images from Mars Express.

Saturn's Hexagon Viewed from the Ground

Leigh Fletcher • February 01, 2013

For the first time, amateur astronomers are capturing spectacular images of Saturn's bizarre north polar hexagon.

Pretty picture: Neptune and Triton

Emily Lakdawalla • February 01, 2013

On a lonely evening, what is one to do but to dip into archival space image data and surface with a gorgeous photo of a crescent Neptune and Triton?

Enceladus: A problem of contrast

Emily Lakdawalla • January 30, 2013

Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.

Weather Report: Mars

Bill Dunford • January 28, 2013

Just like on Earth, clouds and storms often ripple through the Martian atmosphere. You can even check the daily weather report.

Voyager 1 revisited: Io and Europa transiting Jupiter

Björn Jónsson • January 22, 2013

What is the highest resolution global Jupiter mosaic that includes a satellite transit that can be assembled from Voyager images? Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

More Chang'E 2 Toutatis flyby images

Emily Lakdawalla • January 20, 2013

Last week at a meeting of NASA's Small Bodies Assessment Group (SBAG), Han Li of the Chinese Academy of Sciences gave a lengthy presentation on Chang'E 2. Her presentation included a new sequence of photos from the December 13 Toutatis flyby.
