During the third lunar day of Change'3 surface operations the lander operated normally, performing ultraviolet astronomy and imaging Earth's plasmasphere. The rover's instruments were working, but the rover did not move.

Curiosity has tested a new driving mode -- backwards -- and achieved their longest single-day drive in three months. And they've committed to driving to the spot formerly known as

I've been fascinated by Mercury's hollows ever since MESSENGER discovered them. Two recent papers look at where they are found to try to figure out how they form.

Upcoming deep space missions will venture right to the heart of the Solar System.

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.

A few days ago, Curiosity looked westward after sunset and photographed Earth setting toward the mountainous rim of Gale crater.

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.

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

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.

In honor of the 10th anniversary of Spirit's landing on Mars, here is a new view from near the end of that mission.

A pile of Chang'e 3 photos has been released to the Web, and they are much, much better than what I've seen before. They include, for the first time, photos of Earth from the lander.
