Portraits of a planet.

The majority of Dawn's time in the Ceres approach phase will be devoted to continuing ion-powered flight. Let’s take another look at how this remarkable technology is used to deliver the adventurer to the desired orbit around Ceres.

A beautiful Mastcam panorama from sol 528 shows a landscape so much more like Earth than anything we've explored on the Martian surface before.

At long last, on sol 526, Curiosity imaged the part of the weather instrument that was damaged during landing, but no obvious damage is visible, to me anyway. On sol 527 they drove even closer to Dingo Gap, with plans to drive onto the dune in the sol 528 drive.

As a lifetime listener of National Public Radio, it's beyond strange to hear my voice on All Things Considered! I wish it were for a happier reason, but I was invited on by Geoff Brumfiel to talk about the fate of poor Yutu.

The next major mission to Mars will push the technological envelope in way that preserves its budget and fulfills the scientific goals set by the planetary community for this decade.

You thought you were rid of us...but we're back! Following the spectacular and, quite frankly unprecedented, success of the Comet ISON Observing Campaign, we are launching a similar venture for another unique cometary encounter that's happening this year. In October 2014, comet C/2013 A1 (Siding Spring) will pass extremely close to Mars.

Cosmos stumbles with an episode that is plodding, scattered, and more than a little preachy. This episode will only persist in my memory as a shadow of what could have been.

The Sun has set for a second time at Chang'e 3's landing site on the Moon. The lander is operating normally and shut down to sleep as expected, but the rover is not responding properly to Earth command so could not prepare properly for the oncoming lunar night, and likely will not survive it.

The Planetary Society released an official statement today recognizing the unprecedented achievement of maintaining an operating rover on the surface of Mars for a decade.

Over the last few days, Curiosity made steady driving progress to the southwest. For several of those days, an intriguing feature has appeared on the horizon in her images. UPDATE: The Curiosity team has now decided to drive the rover toward the feature, which is now named

Lockheed, the prime contract on the now-defunct Advanced Stirling Radioisotope Generator program, is closing out the project and transferring its hardware to NASA's Glenn Research Center. NASA expects to save about $55 million per year.

In the last month, Curiosity put 222 meters on the odometer in 12 short drives, while regularly assessing the wheels for damage. The rover performed touch-and-go analyses of rocks including Oneida and Kodak, and also took some ChemCam RMI mosaics of rocks near the base of Mount Sharp.
